Tip 2: Reduce salt to lower diastolic blood pressure

Cut down on sodium intake

Reducing sodium is one of the important measures to help lower diastolic blood pressure and reduce stress on the cardiovascular system. When the body consumes too much sodium, more water is retained, making the heart and blood vessels work harder to circulate blood.

• Try to keep sodium intake below 1,500 mg per day.
• Limit the habit of adding extra salt to food at the table.
• Reduce the use of high-sodium dipping sauces.
• Prioritize fresh foods over processed foods.

Understand how much salt you are consuming

Many people don't realize that their daily salt intake often far exceeds recommended levels, increasing the risk of high blood pressure and cardiovascular diseases.

• One teaspoon of table salt contains approximately 2,300 mg of sodium.
• The average sodium intake for many adults can exceed 3,400 mg per day.
• Most sodium does not come from direct seasoning but from packaged foods, canned goods, and fast food.

Limit water retention in the body

Consuming too much sodium causes the body to retain water, increasing the blood volume circulating in the blood vessels. This is one of the reasons for high diastolic blood pressure and increases the burden on the heart.

• Reduce overly salty dishes such as pickled vegetables, dried fish, cold cuts, and canned goods.
• Limit instant noodles, snacks, sausages, and ready-to-eat frozen foods.
• Drink enough water daily to help balance fluids in the body.

Read food labels before buying

Checking nutritional information is a useful habit to control daily sodium intake.

• Prioritize products containing 140 mg of sodium or less per serving.
• Pay attention to ingredients such as sodium, baking powder, baking soda, monosodium glutamate (MSG), or compounds with the symbol Na.
• Compare sodium content between similar products before choosing.

Enhance food flavor without adding salt

Reducing salt doesn't mean food has to be bland. Many natural ingredients can make food more delicious while supporting blood pressure control.

• Use garlic, onion, ginger, or pepper to enhance flavor.

Cutting back on alcohol is one of the important lifestyle changes that helps lower diastolic blood pressure and protect cardiovascular health. While some studies suggest that low levels of alcohol can offer certain heart benefits, excessive drinking increases the risk of high blood pressure, stroke, and many other health problems.

• Minimize regular alcohol consumption.
• Avoid binge drinking or continuous drinking for several days.
• If you have high diastolic blood pressure, consider significantly reducing or stopping alcohol use.

Understand the effect of alcohol on blood pressure

When too much alcohol is consumed, heart rate and blood pressure can increase in the short term. Over the long term, this increases the strain on the cardiovascular system and makes blood pressure control difficult.

• Drinking more than 1–2 units of alcohol per day can increase blood pressure in many people.
• Alcohol can also affect sleep quality, weight, and the body's blood pressure regulation process.
• Reducing alcohol consumption often helps improve the effectiveness of high blood pressure control.

Recognizing a standard drink unit

Many people underestimate the amount of alcohol they consume. Understanding basic conversions will help you control it better.

• Approximately 355 ml of beer equals one standard drink unit.
• Approximately 150 ml of wine equals one standard drink unit.
• Approximately 45 ml of 40% spirits equals one standard drink unit.

Consult your doctor when necessary

If you have a history of high blood pressure, cardiovascular disease, or are taking blood pressure medication, consulting a doctor is essential.

• Ask your doctor about the appropriate level of alcohol consumption for your health condition.
• Do not arbitrarily combine alcohol with blood pressure medication.
• Adhere to the treatment plan and monitor blood pressure regularly.

Limiting or stopping alcohol consumption not only helps lower diastolic blood pressure but also improves cardiovascular health, sleep, and quality of life in the long run.

Part 3: When to see a doctor and take medication for high blood pressure?

Note 1: Understand the diastolic blood pressure reading

Know how to read blood pressure readings

To effectively control and lower diastolic blood pressure, you first need to understand the meaning of the numbers displayed on the blood pressure monitor. Each measurement usually shows two important readings that reflect the activity of the heart and blood vessels.

• The top number is systolic blood pressure.
• The bottom number is diastolic blood pressure.
• Both readings need to be monitored for a comprehensive assessment of cardiovascular health.
• You should not focus only on one reading and ignore the other.

What is systolic blood pressure?

Systolic blood pressure is the pressure exerted by blood on the artery walls when the heart contracts to pump blood throughout the body.

• This is the top number in a blood pressure reading.
• It represents the force of blood flow when the heart is working hardest.
• A high reading can increase the risk of cardiovascular disease and stroke.

What is diastolic blood pressure?

Diastolic blood pressure is the pressure in the arteries when the heart is at rest between beats. This is when the heart relaxes and prepares for the next contraction.

• This is the bottom number in a blood pressure reading.
• It reflects the elasticity and resistance of the vascular system.
• Prolonged high readings can increase the risk of damage to the heart, kidneys, and blood vessels.

The relationship between systolic and diastolic blood pressure

In many cases, factors that increase blood pressure will affect both readings simultaneously. Therefore, measures to improve blood pressure often benefit both systolic and diastolic blood pressure.

• Healthy eating helps stabilize overall blood pressure.
• Weight loss can improve both readings.
• Regular exercise helps strengthen cardiovascular health.
• Reducing stress and getting enough sleep helps stabilize blood pressure.

Regular blood pressure monitoring

Regular blood pressure measurement helps detect abnormal changes early and assess the effectiveness of lifestyle adjustments.

• Measure blood pressure at the same time each day if possible.

Regularly monitoring diastolic blood pressure helps you know if changes in your diet, exercise, and lifestyle are yielding positive results. This is also a simple way to detect early abnormal signs and proactively protect your cardiovascular health.

• Measure blood pressure at home with a personal blood pressure monitor.
• Get checked at a pharmacy or medical facility.
• Record results after each measurement to track trends.
• Measure under resting conditions and at relatively consistent times of the day.

Understand diastolic blood pressure levels

Understanding blood pressure thresholds helps you accurately assess your health status and take appropriate action.

• Normal diastolic blood pressure: approximately 70–80 mmHg.
• Risk of hypertension: 80–89 mmHg.
• High diastolic blood pressure: 90 mmHg or higher.
• Some young people or those who exercise regularly may have lower than average readings and still be normal.

Develop an appropriate monitoring schedule

Blood pressure measurement frequency should be adjusted based on your current health condition.

• If you have just been diagnosed with high blood pressure or high diastolic blood pressure, you should measure twice a day during the first week.
• Take one measurement in the morning and one in the evening.
• When blood pressure starts to stabilize, you can reduce it to 2–3 times per week.
• After good control, you can monitor 1–2 times per month as advised by your doctor.

Ensure proper blood pressure measurement

Measurement results are only valid when performed correctly.

• Rest for at least 5 minutes before measuring.
• Do not smoke, drink coffee, or engage in strenuous activity before measuring.
• Sit upright with your arm at heart level.
• Measure multiple times and take the average result if necessary.

Not just high blood pressure is concerning

Many people focus on lowering diastolic blood pressure but forget that blood pressure that is too low can also affect health.

• Diastolic blood pressure that is too low can reduce blood flow to vital organs.
• It can cause dizziness, fatigue, or lightheadedness.
• In some cases, this condition is associated with medical problems that require medical evaluation.
• If blood pressure is persistently abnormally low, it is advisable to consult a doctor.

Monitoring to prevent cardiovascular complications

Maintaining the habit of checking blood pressure not only helps evaluate the effectiveness of diastolic blood pressure reduction but also supports the prevention of many dangerous complications.

• Early detection of hypertension risk.
• Reduced risk of stroke and myocardial infarction.
• Assists doctors in developing appropriate treatment plans.
• Helps you proactively manage your long-term health.

Regular monitoring of diastolic blood pressure is a small habit that brings great value. The recorded numbers over time will help you understand your health status and make timely adjustments to protect your cardiovascular health more effectively.

Note 3: Consult a doctor

See a doctor for more effective blood pressure control

Even if you have applied many home remedies to lower diastolic blood pressure, regular doctor visits are still very important. Medical professionals can comprehensively assess cardiovascular health, identify potential risk factors, and provide suitable solutions for each individual.

• Do not rely solely on home blood pressure readings.
• Undergo regular health check-ups as recommended.
• Proactively discuss any unusual symptoms or health changes.
• Bring your blood pressure log to your appointment for a more accurate assessment by the doctor.

Develop a suitable treatment plan

Each person has different causes and degrees of high diastolic blood pressure. Therefore, treatment needs to be individualized rather than applying a general formula for everyone.

• The doctor will assess cardiovascular risk factors.
• Consider current diet, exercise, and lifestyle habits.
• Propose lifestyle changes appropriate to the health condition.
• Prescribe medication if necessary.

Control blood pressure at a safe level

The goal is not only to lower blood pressure but also to maintain it within an appropriate range. Blood pressure that is too low can also cause undesirable effects on the body.

• Avoid self-medicating or taking supplements to lower blood pressure.
• Do not try to lower blood pressure too quickly in a short period.
• Monitor the body's reaction during treatment.
• Follow the doctor's instructions to maintain stable blood pressure levels.

Especially important if suffering from chronic diseases

Some diseases can increase the risk of complications related to blood pressure and cardiovascular health. In these cases, regular medical monitoring is essential.

• People with cardiovascular disease.
• People with diabetes.
• People with chronic kidney disease.
• People with a history of stroke or circulatory problems.

Discuss current medications with your doctor

Some medications can affect blood pressure or interact with antihypertensive drugs.

• Provide a complete list of current medications and supplements.
• Do not arbitrarily stop or change medication dosages.
• Consult a doctor before using any health support product.
• Adhere to follow-up appointments and monitoring as professionally advised.

Proactively protect long-term cardiovascular health

The combination of lifestyle changes and medical monitoring helps improve the effectiveness of blood pressure control and reduce the risk of future complications.

There is no one-size-fits-all medication. The doctor will choose the treatment option based on blood pressure readings and co-existing medical conditions.

• Consider age and medical history.
• Assess overall cardiovascular risk.
• Consider current medications.
• Adjust the treatment regimen as needed.

Some commonly used drug groups

There are many different drug groups that help control high blood pressure. The choice depends on the specific health condition of each patient.

• Thiazide diuretics are often used for many cases of hypertension.
• Beta-blockers may be prescribed for some people with cardiovascular disease.
• Calcium channel blockers are a common choice for treating hypertension.
• ACE inhibitors (ACEI) or angiotensin II receptor blockers (ARB) are often considered for people with diabetes, kidney disease, or certain cardiovascular diseases.

Do not arbitrarily choose or change medication

Incorrect use of medication can reduce treatment effectiveness or cause unwanted side effects.

• Do not use medication based on others' experiences.
• Do not arbitrarily increase or decrease dosages.
• Report any side effects to your doctor.
• Consult a specialist before taking any additional health supplements or other medications.

Not everyone with high diastolic blood pressure needs medication

In many cases, especially when diastolic blood pressure is only slightly elevated and not accompanied by systolic hypertension, doctors may prioritize lifestyle changes before considering medication.

• Adjust diet.
• Increase physical activity.
• Lose weight if overweight or obese.
• Manage stress and improve sleep.

Monitor blood pressure throughout treatment

Regular monitoring helps assess the effectiveness of medication and assists the doctor in adjusting the regimen as needed.

• Measure blood pressure regularly at home.
• Record results to track trends.

DASH diet supports blood pressure reduction

Adopt the DASH diet to control blood pressure

The DASH (Dietary Approaches to Stop Hypertension) diet is one of the most widely recommended nutritional approaches for people with high diastolic blood pressure and high blood pressure. This diet focuses on natural, nutrient-rich foods and limits ingredients that can raise blood pressure.

• Increase whole grains in daily meals.
• Eat plenty of green vegetables and fresh fruits.
• Prioritize lean protein sources and low-fat foods.
• Limit saturated fats, processed foods, and high-salt foods.

Benefits of the DASH diet

DASH not only helps lower diastolic blood pressure but also provides many benefits for cardiovascular and metabolic health.

• Helps lower blood pressure naturally.
• Helps improve blood cholesterol.
• Supports weight management.
• Reduces the risk of heart disease and stroke.

Change lifestyle gradually and sustainably

When trying to improve blood pressure, many people tend to make changes too quickly. However, sudden adjustments can sometimes be unsuitable for individual health conditions.

• Implement dietary changes step-by-step.
• Increase physical activity according to your body's capabilities.
• Maintain new habits consistently.
• Consult a doctor before making significant changes to diet or exercise.

Consult your doctor before developing a treatment plan

Each person has different health conditions, medical histories, and cardiovascular risks. Therefore, professional evaluation is essential before implementing any blood pressure control program.

• Undergo regular general health check-ups.
• Fully share your medical history and current medications.
• Undergo prescribed tests if necessary.
• Follow individualized treatment guidelines.

Lower blood pressure is not always better

Many people focus only on lowering blood pressure, forgetting that excessively low blood pressure can also affect health.

• The goal is to maintain blood pressure within a safe range.
• Excessively low diastolic blood pressure can reduce blood flow to vital organs.
• This can increase the risk of cardiovascular events in some individuals.
• Do not arbitrarily use medications or measures to lower blood pressure excessively.

Pay special attention when diastolic blood pressure drops too low

Regular monitoring of blood pressure will help detect abnormal changes early.

• Diastolic blood pressure below 70 mmHg needs careful monitoring in some cases.
• Diastolic blood pressure should not be allowed to drop below 60 mmHg without medical indication and supervision.
• If dizziness, fatigue, lightheadedness, or fainting occurs, contact a doctor for evaluation.
• Maintain regular blood pressure measurements to ensure readings remain within the appropriate range.

The DASH diet combined with appropriate exercise, weight management, and regular medical monitoring is a crucial foundation for safely lowering diastolic blood pressure, while protecting cardiovascular health and reducing the risk of long-term complications.
