Acid reflux and hoarseness: 12 ways to restore your vocal cords

Prolonged hoarseness, a burning sensation in the throat, or a feeling of a lump in the throat may not only be due to pharyngitis or talking too much. Acid reflux causing hoarseness is also a common cause, especially when acid or stomach fluid flows back up into the throat and larynx, irritating the vocal cords. A type of reflux called laryngopharyngeal reflux (LPR) can occur without the typical heartburn symptoms.

If this condition persists, the vocal cords can become irritated, leading to a hoarse, weak, or easily fatigued voice when speaking. In this article, Tiptory will help you understand how to treat reflux laryngitis, control irritating factors, and apply simple methods to restore vocal cords such as voice rest, adequate hydration, and avoiding smoke. By addressing the root cause, your throat has a better chance of recovering rather than just trying to "cure hoarseness" temporarily.

Part 1: How to protect your vocal cords when you have reflux

Method 1: Control reflux to protect your vocal cords

Controlling reflux is an important step to reduce laryngeal irritation

• When stomach acid frequently refluxes into the esophagus and throat, the irritation can contribute to hoarseness, coughing, or discomfort in the throat. Therefore, if you are looking for ways to treat reflux laryngitis or restore vocal cords, controlling the cause of reflux should be prioritized over just focusing on your voice.

Adjust diet and eating times

1. Monitor which foods make your symptoms of acid reflux causing hoarseness more pronounced. Common triggers include fatty foods, chocolate, coffee, mint, spicy foods, alcohol, and some acidic foods. Not everyone is sensitive to all of these groups, so it's best to identify triggers specific to you.

2. Avoid eating close to bedtime. People with reflux should try to finish their meals at least 2–3 hours before lying down. This habit helps reduce the likelihood of stomach fluids refluxing when the body is in a reclining position.

Adjust sleeping position

• If you often experience nighttime reflux, you can elevate the head of your bed by about 15–25 cm using a wedge or appropriate risers. Simply stacking more pillows often does not provide as effective an elevation as raising the head of the bed.

• This is one of the practical measures that can help reduce stomach reflux into the larynx, thereby limiting further irritation to the throat and vocal cords.

Change some daily habits

• If you are overweight or obese, losing weight can help reduce GERD symptoms in some people. Additionally, you should avoid smoking as tobacco can worsen reflux.

• Avoid wearing overly tight clothing around the abdomen and pay attention to activities or times that increase reflux symptoms. Resting properly after meals also helps limit situations that easily worsen symptoms.

Consult a doctor if reflux persists

• If lifestyle changes do not alleviate hoarseness due to acid reflux, a doctor can assess whether you truly have GERD, laryngopharyngeal reflux, or another cause. Do not assume that all cases of hoarseness are due to stomach acid.

• When medication is needed, proton pump inhibitors (PPIs) are one of the main classes of drugs used to control GERD. The choice of medication, dosage, and duration of treatment should be based on diagnosis and doctor's guidance.

Surgery is only for specific cases

• Anti-reflux surgery is not the first option for everyone. A doctor may consider this method when GERD has been objectively confirmed but is not well controlled with medical treatment, the patient is intolerant to medication, or falls into an appropriate indication group.

• Before surgery, patients typically need thorough evaluation to confirm that reflux is indeed the cause of the symptoms. Therefore, do not seek surgery simply to recover vocal cords quickly.

The goal is to prevent further damage

• Treating reflux laryngitis is not just about short-term relief of burning sensations or hoarseness. More importantly, it is about reducing reflux, limiting repeated irritation, and creating conditions for the larynx to recover.

• If hoarseness persists, difficulty swallowing, a feeling of food getting stuck, shortness of breath, vomiting blood, or black stools, seek medical attention instead of self-treating at home. These could be signs requiring evaluation for more serious causes and complications.

Method 2: Eat small meals to reduce reflux

Eating smaller, more frequent meals can help limit reflux

• Instead of three overly large meals, you can divide your food intake into smaller, more frequent meals throughout the day if this works for your body. Eating too much at once can overfill the stomach and make reflux symptoms more likely to occur.

• However, not everyone needs to eat 5–6 meals a day. More importantly, it's about controlling portion sizes, avoiding overeating, and monitoring which foods or habits worsen your symptoms of acid reflux causing hoarseness.

Do not lie down immediately after eating

1. After a meal, you should maintain an upright posture and avoid lying down for about 2–3 hours, especially if you often experience nighttime reflux.

2. Avoid bending over or applying strong pressure to the abdomen immediately after eating. These changes can help reduce the likelihood of stomach fluids refluxing into the esophagus and throat.

Avoid eating close to bedtime

• If you frequently experience hoarseness due to acid reflux, try to finish your dinner at least 2–3 hours before going to bed. This is one of the lifestyle changes often recommended to reduce nighttime GERD symptoms.

• If symptoms still occur when lying down, especially heartburn, regurgitation, or coughing at night, consult a doctor for evaluation and appropriate treatment guidance.

Avoid eating too close to exercise time

• Avoid eating a large meal right before exercise, especially activities that involve abdominal compression or frequent bending. If you need to eat before exercise, choose a moderate portion and allow enough time for digestion.

• The goal is not to starve yourself before exercise but to prevent an overly full stomach, thereby reducing the risk of stomach fluids refluxing into the esophagus and larynx.

Support vocal cord recovery

• When reflux frequency is well controlled, the throat and vocal cords will be less exposed to irritating factors. This is an important foundation in addition to voice rest, adequate hydration, and avoiding smoke if you are recovering your vocal cords.

• If hoarseness persists or recurs frequently despite changes in eating habits, do not continue self-treatment. A doctor may need to check if reflux is truly the cause or if there are other laryngeal issues.

Method 3: Limit foods that cause reflux

Limit foods that can worsen reflux symptoms

• Not everyone with acid reflux causing hoarseness reacts the same way to food. However, some drinks and foods can make GERD or laryngopharyngeal reflux (LPR) symptoms more pronounced in individuals.

• You can try reducing or temporarily stopping groups often associated with symptoms, such as:

  • Coffee and caffeinated beverages.

  • Alcoholic beverages.

  • Chocolate.

  • Carbonated soft drinks.

  • High-fat foods or spicy dishes if they cause you discomfort.

  • Acidic foods like oranges, lemons, and tomatoes if you notice they trigger symptoms.

Prioritize simple, easily digestible foods

1. When managing reflux, prioritize moderate portions and foods that your body tolerates well. Rice, bread, oatmeal, vegetables, and some low-symptom fruits can be good choices.

2. Bananas can be consumed if you find them easy to eat, but they are not a mandatory food for treating reflux laryngitis. More importantly, build a balanced diet and identify the specific foods that trigger your symptoms.

Monitor foods that cause hoarseness

• Instead of avoiding too many types of food at once, you can keep a record of what you've eaten and when heartburn, regurgitation, coughing, or hoarseness due to acid reflux occurred. This helps identify triggers more clearly and avoids unnecessary dietary restrictions.

• If a food or drink consistently increases symptoms, reduce the amount or temporarily eliminate it to observe the change.

Protect vocal cords by controlling the cause

• Food is not the sole cause of laryngeal damage from reflux. Overeating, lying down immediately after eating, smoking, being overweight, or nighttime reflux can also contribute to persistent symptoms.

• Therefore, to restore vocal cords, dietary adjustments should be combined with other reflux control measures rather than just focusing on avoiding acidic foods.

Do not over-restrict your diet

• If you have to eliminate many food groups due to persistent symptoms, consult a doctor or nutritionist to ensure you still get enough energy and nutrients.

• Especially if hoarseness persists, swallowing pain, difficulty swallowing, persistent cough, or symptoms do not improve despite dietary changes, you should be examined to determine the cause rather than assuming it is acid reflux causing hoarseness.

Method 4: Limit foods that cause reflux

Limit foods that can worsen reflux symptoms

• Not everyone with acid reflux causing hoarseness reacts the same way to food. However, some drinks and foods can make GERD or laryngopharyngeal reflux (LPR) symptoms more pronounced in individuals.

• You can try reducing or temporarily stopping groups often associated with symptoms, such as:

  • Coffee and caffeinated beverages.

  • Alcoholic beverages.

  • Chocolate.

  • Carbonated soft drinks.

  • High-fat foods or spicy dishes if they cause you discomfort.

  • Acidic foods like oranges, lemons, and tomatoes if you notice they trigger symptoms.

• If a food or drink consistently increases symptoms, reduce the amount or temporarily eliminate it to observe the change.

• Food is not the sole cause of laryngeal damage from reflux. Overeating, lying down immediately after eating, smoking, being overweight, or nighttime reflux can also contribute to persistent symptoms.

• Therefore, to restore vocal cords, dietary adjustments should be combined with other reflux control measures rather than just focusing on avoiding acidic foods.

Do not over-restrict your diet

• If you have to eliminate many food groups due to persistent symptoms, consult a doctor or nutritionist to ensure you still get enough energy and nutrients.

• Especially if hoarseness persists, swallowing pain, difficulty swallowing, persistent cough, or symptoms do not improve despite dietary changes, you should be examined to determine the cause rather than assuming it is acid reflux causing hoarseness.

Method 5: Speak softly to allow vocal cords to recover

Speak at a natural volume instead of whispering

• When vocal cords are irritated by acid reflux causing hoarseness, many people tend to whisper, thinking it helps "save" their voice. In reality, whispering does not always help the vocal cords rest and can increase vocal strain.

• If you need to communicate, speak in a natural voice, at a moderate volume, without trying to speak loudly or forcing your voice down into a whisper. This is an important principle when recovering vocal cords.

Avoid shouting and trying to speak loudly

• Shouting, cheering too loudly, or speaking loudly for extended periods can increase the impact force on the vocal cords, especially when the vocal cords are already inflamed or irritated.

• If the environment is too noisy, instead of trying to speak louder, move to a quieter place or use sound amplification devices when prolonged communication is needed.

Give your voice time to rest

1. Limit long conversations when you are hoarse or have a sore throat.

2. Avoid constantly clearing your throat. If you feel a lump in your throat, sip water or swallow gently instead of forcefully clearing your throat.

3. Do not overuse your voice while your vocal cords are recovering. Adequate voice rest can help reduce further irritation.

Combine voice protection with reflux control

• Changing your speaking habits alone will not address the cause if laryngopharyngeal reflux persists. Acid or stomach fluids continuing to contact the throat area can prolong hoarseness.

• Therefore, treating reflux laryngitis should simultaneously focus on controlling reflux, limiting voice-straining behaviors, and maintaining adequate hydration.

When should you see a doctor?

• If hoarseness due to acid reflux persists or recurs frequently, especially if you have rested your voice and controlled reflux but there is no improvement, consult an ENT doctor.

• Persistent hoarseness is not always due to reflux. A doctor can examine your larynx to find other causes and determine the appropriate method for vocal cord recovery.

Method 6: Avoid clearing your throat to protect your vocal cords

Limit throat clearing when your throat is irritated

• Gastric reflux hoarseness can cause a sensation of a lump in the throat, itching, or mucus in the throat, leading to a constant urge to clear your throat. However, strong and repeated throat clearing can cause vocal cord structures to collide, thereby increasing irritation and making voice recovery difficult.

• Instead of trying to clear your throat to "cleanse" it, try gentler methods to alleviate the discomfort.

Replace throat clearing with gentler actions

1. Take a sip of water: Sip small amounts to moisten the throat and reduce itching or dryness.

2. Gentle swallow: When you feel the urge to clear your throat, try swallowing once instead of applying strong force to your larynx.

3. Exhale gently through your mouth: You can exhale gently to reduce the sensation of a lump in your throat without putting strong pressure on your vocal cords.

4. Gentle cough when truly necessary: Do not try to suppress a strong cough caused by phlegm or irritants in the airway. The goal is to avoid continuous coughing or throat clearing when unnecessary.

Do not strain your voice when hoarse

• When vocal cords are irritated, constantly clearing your throat, coughing, or trying to speak to check if your voice has "returned" can cause the laryngeal area to continue to undergo mechanical stress.

• If you are looking to recover your vocal cords, prioritize drinking enough water, speaking at a natural volume, and reducing activities that strain your voice.

Control the cause of reflux

• Throat clearing is merely a reaction to irritation; it does not address the underlying cause. If laryngopharyngeal reflux persists, the sensation of a lump in the throat and hoarseness may recur.

• Therefore, treating reflux laryngitis requires combining reflux control with voice care, rather than just trying to eliminate the sensation of a lump in the throat.

See a doctor if hoarseness persists

• If you frequently need to clear your throat or cough, experience persistent hoarseness, pain when speaking, difficulty swallowing, or worsening symptoms, you should see an ENT doctor to examine your larynx.

• Do not assume that all cases of hoarseness due to gastric reflux originate from acid. Allergies, infections, vocal cord damage, smoking, and many other causes can also lead to similar symptoms.

Method 7: Be cautious with throat-drying medications

Be cautious with decongestants when hoarse

• When you have a cold or stuffy nose, decongestants can help relieve symptoms, but some can cause dry mouth and respiratory tract membranes. Dryness can make your throat more uncomfortable and hinder the process of vocal cord recovery. Voice care guidelines also recommend paying attention to medications that can dry out the throat when assessing hoarseness.

• However, you should not stop decongestants or prescribed medications on your own just because you are hoarse. Whether medication changes are needed depends on the type of medication, the reason for its use, and each person's health condition.

Check for medications that can dry out mucous membranes

• In addition to decongestants, some groups of medications can also affect mucous membrane moisture or contribute to hoarseness. Antihistamines, anticholinergic drugs, and some diuretics are examples that have been noted to have a drying effect on mucous membranes.

• Therefore, if gastric reflux hoarseness persists, inform your doctor about all medications, supplements, and over-the-counter drugs you are taking. This is important information to distinguish symptoms caused by reflux from medication side effects or other causes.

Do not stop underlying disease medications on your own

1. Check the name and side effects of each medication you are taking.

2. If you notice dry mouth, dry throat, or hoarseness appearing after starting a new medication, talk to your doctor or pharmacist.

3. Do not arbitrarily reduce the dose or stop antidepressants, Parkinson's disease medications, or neurological disorder medications. Your doctor may consider adjusting the medication or choosing an alternative if truly necessary.

Keep your throat adequately hydrated

• Drinking water regularly throughout the day can help reduce the sensation of a dry throat. When treating reflux laryngitis, maintaining adequate hydration should be considered part of voice hygiene, in addition to limiting smoke and avoiding excessive voice use. AAO-HNSF guidelines on hoarseness also emphasize the role of adequate hydration and avoiding irritants.

• However, drinking a lot of water does not eliminate the cause of hoarseness if the problem is actually laryngopharyngeal reflux or another laryngeal condition.

Don't assume hoarseness is due to reflux

• If hoarseness does not improve or lasts longer than 4 weeks, professional guidelines recommend a laryngeal evaluation with endoscopy or referral to a doctor capable of performing laryngeal endoscopy.

• This is especially important if there is shortness of breath, difficulty swallowing, a neck mass, a history of smoking, or other risk factors. Correctly identifying the cause will help select the appropriate way to recover vocal cords, rather than just focusing on treating reflux.

Method 8: Avoid smoke to protect vocal cords

Quit smoking and avoid smoke

• Cigarette smoke contains many irritants that can dry and irritate the vocal cords. Smoking can also cause coughing, putting additional strain on the larynx and making hoarseness difficult to improve. The NIDCD recommends not smoking and avoiding secondhand smoke to protect vocal health.

• If you are recovering your vocal cords due to gastric reflux hoarseness, consider avoiding tobacco as part of your voice care process, in addition to controlling reflux and limiting excessive voice use.

Avoid secondhand smoke too

• Not only direct smokers are affected. Smoke in homes, restaurants, workplaces, or enclosed areas can also irritate the respiratory tract and larynx.

• If you must be in a smoky environment, actively move to a well-ventilated area, avoid enclosed spaces where people smoke, and keep your living environment clean and free of irritants.

Pay attention to air quality

• Polluted air, dusty air, or air containing smoke and irritant particles can also affect the voice. Professional guidelines on hoarseness note that smoke, particulate matter, pollution, and dry environments can increase the risk of voice disorders.

• When outdoor air quality is poor, prolonged exposure to polluted environments should be limited. Indoors, you can keep the space well-ventilated and maintain appropriate humidity if the air is too dry.

Don't just focus on the vocal cords

• If laryngopharyngeal reflux persists, quitting smoking will not replace treating the underlying cause. Simultaneously control reflux, drink enough water, rest your voice appropriately, and avoid factors that irritate your throat.

• The goal of treating reflux laryngitis is to reduce inflammatory and irritating agents to allow the vocal cords to recover, rather than just trying to get rid of hoarseness in the short term.

Persistent hoarseness needs to be checked

• Do not assume hoarseness is due to reflux or smoking. Hoarseness can stem from many different causes, including laryngitis, voice abuse, vocal cord damage, and more serious conditions.

• If hoarseness does not improve within 4 weeks, the American Academy of Otolaryngology guidelines recommend a laryngeal examination or referral to a doctor capable of performing laryngeal endoscopy. For individuals with a history of smoking or serious signs, evaluation may need to be done sooner.

Part 2: How to soothe vocal cords affected by reflux

Method 1: Humidify the air to protect vocal cords

Maintaining appropriate humidity helps reduce dryness and irritation of the larynx

• Air passes through the larynx with each breath. When the environment is too dry, the respiratory tract mucous membranes and vocal cord surfaces can dry out, making the throat uncomfortable and making the voice tire more easily. Guidelines from the National Institute on Deafness and Other Communication Disorders (NIDCD) recommend using a humidifier indoors, especially during dry seasons or when indoor air is too dry. 

• This can be helpful when you are recovering your vocal cords, especially if gastric reflux hoarseness is accompanied by dryness or throat irritation.

Place a humidifier in the bedroom if the air is too dry

1. You can place a humidifier in the bedroom to maintain humidity during rest and sleep.

2. NIDCD currently recommends indoor humidity levels of about 30% when using a humidifier for vocal health. Do not try to make the air too humid, as high humidity can create a favorable environment for mold and allergens.

3. It is recommended to use the machine according to the manufacturer's instructions and clean the device regularly to limit the spread of bacteria, mold, or dirt into the air.

Don't forget to drink enough water

• A humidifier only helps improve the air environment; it does not replace adequate hydration for the body. Drinking water regularly is one of the voice care measures recommended by the NIDCD and professional guidelines on hoarseness.

• If you are treating reflux laryngitis, combine adequate hydration with reflux control, limiting smoke, and avoiding excessive voice use to reduce factors that may continue to irritate the larynx.

No need for a humidifier if the environment is already humid enough

• Humidifiers are especially useful in dry environments. If the room already has appropriate humidity, increasing it further does not mean the vocal cords will recover faster.

• The goal is to create a comfortable environment for the respiratory tract, not to turn the bedroom into a "tropical greenhouse." According to AAO-HNS guidelines, indoor environmental humidity can help reduce vocal cord surface dehydration in dry environments.

Reflux control is still an important step

• If hoarseness due to gastric reflux occurs frequently, a humidifier only helps reduce dryness and irritation; it does not treat the underlying cause of reflux. The NIDCD also notes that gastric reflux is one of the causes of voice problems and recommends that people with persistent GERD talk to their doctor about how to control symptoms.

• Therefore, to recover vocal cords more effectively, combine humidification, adequate hydration, voice care, and control of laryngopharyngeal reflux when it is identified as the cause.

Method 2: Drink enough water to restore vocal cords

Drinking enough water helps keep the larynx moist

• When experiencing gastric reflux hoarseness, drinking enough water is an important part of voice care. Water helps maintain body hydration and supports a favorable environment for vocal cord activity. The NIDCD recommends drinking enough water, especially when exercising, and resting your voice when necessary. 

• Instead of drinking a large amount at once, it is better to drink water regularly throughout the day according to your body's needs. Plain water is the simplest and most suitable choice for staying hydrated.

Prioritize less irritating beverages

1. Prioritize plain water and low-sugar beverages if you tolerate them well.

nl>

2. If consuming coffee or caffeinated beverages, drink extra water to avoid dehydration. The NIDCD recommends balancing caffeine and alcohol intake with adequate hydration.

nl>

3. Limit alcohol, especially if you notice it exacerbates symptoms of laryngopharyngeal reflux or dry throat.

nl>

Don't assume more water is always better

• The goal is to stay adequately hydrated, not to force yourself to drink excessively. Fluid needs vary depending on individual body type, weather, activity level, and health status.

nl>

• If your doctor has instructed you to limit fluid intake due to heart disease, kidney disease, or another health condition, follow those specific instructions instead of general hydration recommendations.

nl>

Check medications if you frequently experience dry mouth or throat

• Some medications can dry out the vocal cords or respiratory tract mucous membranes, including some cold and allergy medications. The NIDCD recommends that individuals with voice problems discuss with their doctor which medications might worsen dryness.

nl>

• Do not stop prescribed medications on your own due to hoarseness or dry throat. If you suspect your current medication is contributing to dryness, provide a complete list of medications to your doctor or pharmacist for evaluation.

nl>

Combine water intake with voice recovery measures

• Adequate hydration only supports vocal cord care; it does not directly treat the underlying cause of reflux. If hoarseness is due to gastric reflux, GERD or LPR must be simultaneously managed according to appropriate guidelines.

nl>

• To recover vocal cords, the NIDCD also recommends voice rest when needed, avoiding speaking or singing when hoarse, not smoking, and avoiding irritants.

nl>

Persistent hoarseness should not be treated solely with increased water intake

• Gastric reflux can cause hoarseness, but it is not the only cause. The NIDCD notes many other causes such as respiratory infections, voice abuse, vocal cord damage, and certain laryngeal diseases.

nl>

• If hoarseness lasts longer than 3 weeks, especially when not related to a cold or flu, or is accompanied by difficulty swallowing, pain when speaking or swallowing, shortness of breath, coughing up blood, or complete voice loss, seek medical attention to find the cause instead of continuing self-care at home.

nl>

Method 3: Soothe your throat when hoarse

Use lozenges or chew gum to reduce dry throat

• When your throat is dry, sore, or uncomfortable due to gastric reflux hoarseness, you can use sugar-free lozenges or chew gum to stimulate saliva production. Saliva helps moisten the oral cavity and throat, thereby reducing dryness and discomfort.

nl>

• However, this is only a supportive measure for voice care, not a direct treatment method for the underlying cause of reflux. The NIDCD recommends maintaining adequate hydration and proper voice care when experiencing voice problems.

nl>

Prioritize sugar-free products

1. Choose sugar-free lozenges or sugar-free gum if used frequently. This helps limit added sugar while still stimulating saliva production.

nl>

2. If lozenges with mint or cooling ingredients make you notice your laryngopharyngeal reflux worsening, stop using them and choose a more suitable product.

nl>

3. Do not rely on lozenges to mask persistent hoarseness. If your vocal cords are continuously irritated, you need to find and address the cause instead of just soothing the symptoms.

nl>

Combine drinking water and voice rest

• Lozenges or gum do not replace water. Continue to drink water regularly throughout the day to help maintain hydration for your body and voice. The NIDCD also recommends adequate hydration and voice rest throughout the day to protect your vocal cords.

• When recovering vocal cords, it's best to avoid excessive talking, shouting, or trying to speak when your voice is already hoarse and fatigued. This helps reduce further strain on your vocal cords during the healing process.

Do not use lozenges as a substitute for reflux treatment

• If hoarseness due to gastric reflux recurs, lozenges only provide short-term relief from dry or scratchy throat sensations. GERD and LPR are potential causes of voice problems due to refluxed fluids irritating the tissues of the throat and larynx.

• Therefore, treating reflux laryngitis requires focusing on reflux control alongside voice care, rather than just seeking to soothe the throat.

Persistent hoarseness requires investigation

• If hoarseness lasts longer than 3 weeks, especially when unrelated to a cold or flu, you should seek medical attention to determine the cause. Earlier consultation is needed if you experience difficulty swallowing, pain when speaking or swallowing, shortness of breath, coughing up blood, a lump in your neck, or complete voice loss for several days.

• Identifying the correct cause is a crucial step for safe vocal cord recovery and avoiding inappropriate treatment.

Method 4: Gargle with warm salt water to soothe your throat

Gargling with warm salt water can help soothe your throat

• When your throat is dry, sore, or uncomfortable during episodes of gastric reflux causing hoarseness, gargling with warm salt water can help alleviate symptoms. This is a self-care measure recommended by the NHS for laryngitis or sore throats.

• However, salt water primarily helps to reduce throat discomfort; it does not treat the underlying cause of reflux and does not directly heal vocal cord damage. If the goal is vocal cord recovery, controlling reflux and proper voice care are still necessary.

How to prepare salt water correctly

1. Add about 1/2 teaspoon of salt to a glass of warm water and stir until the salt dissolves completely.

2. The water should only be lukewarm, not too hot, to avoid burning or irritating the throat lining.

3. Take a small amount of the solution, tilt your head back slightly, and gargle in the back of your throat for a short period.

4. Spit out the solution after gargling. Do not swallow the salt water. The NHS also advises against salt water gargling for young children as they may not be able to control spitting out the solution effectively.

No need to gargle too vigorously

• The purpose of warm salt water is to soothe the throat area, not to apply strong force to the larynx. Gargle gently, avoiding excessive clearing of the throat or forceful coughing after gargling.

• If you are experiencing hoarseness due to gastric reflux, constant throat clearing or forceful coughing can continue to strain your vocal cords. Proper voice care, adequate hydration, and resting your voice when needed are still crucial factors.

Combine with other vocal cord care measures

• Warm salt water is only a supportive measure. To treat reflux laryngitis, you should simultaneously control reflux-contributing factors, drink plenty of water, avoid smoking, and limit excessive talking or speaking when your voice is hoarse.

• If your throat is frequently dry, you can combine adequate hydration with maintaining proper indoor humidity. The NIDCD also recommends drinking enough water and using a humidifier when the indoor environment is too dry to support voice care.

Do not use salt water to delay seeking medical attention

• If hoarseness lasts longer than 3 weeks, especially when unrelated to a cold or flu, or if you experience difficulty swallowing, pain when speaking or swallowing, shortness of breath, coughing up blood, a lump in your neck, or complete voice loss for several days, you should seek medical attention to find the cause.

• Laryngopharyngeal reflux can cause voice problems, but hoarseness can also have many other causes. Identifying the correct cause is a crucial step to choose a safe and effective way to recover vocal cords.

LPR differs from GERD in terms of reflux location and mechanism

• Laryngopharyngeal reflux (LPR) and gastroesophageal reflux disease (GERD) are related but not entirely the same. The key difference lies in the location of reflux and the associated esophageal sphincters.

• With GERD, stomach contents primarily reflux past the lower esophageal sphincter (LES) into the esophagus. Patients typically experience classic symptoms such as heartburn, acid regurgitation, or a sour taste in the mouth.

• With LPR, stomach contents can travel higher up into the throat and larynx. This condition involves the function of the upper esophageal sphincter (UES) and can cause hoarseness, coughing, a feeling of a lump in the throat, or frequent throat clearing.

• Therefore, people with laryngopharyngeal reflux may not experience obvious heartburn symptoms like those with GERD. This is why hoarseness due to gastric reflux can sometimes be difficult to recognize if only relying on heartburn symptoms.

• However, it should not be understood that LPR is simply "GERD but with higher reflux." The mechanism of LPR is complex, and diagnosis requires considering medical history, symptoms, and in some cases, an ENT examination or specialized tests. Therefore, if hoarseness persists, it's important to seek out the cause rather than self-diagnosing it as due to stomach acid.
