When we talk about blood pressure (BP), we consider two key factors: systolic (SBP) and diastolic blood pressure (DBP). SBP is related to the force used when the heart contracts, with DBP represents the lowest recorded pressure just before the next contraction. [1]

Any condition that dilates the blood vessels can cause low diastolic blood pressure symptoms. These can include thyroid complications, physical activity, anemia, heart valve disorders, allergic reactions, and more.

This guide provides a quick overview of how low diastolic blood pressure affects the system.

Low Diastolic Blood Pressure – What Is It?

For most adults, a healthy blood pressure reading typically falls under 120/80 mm Hg. Low blood pressure, also known as hypotension, is when it’s below 90/60 mm Hg.

Low diastolic blood pressure, or isolated diastolic blood pressure, occurs when the diastolic pressure drops below 60 mm Hg while the systolic pressure stays within a normal range. [2]

During the heart’s resting phase, the coronary arteries take in and deliver oxygen-rich blood to nourish the heart. If the diastolic pressure drops excessively, the heart may not receive the necessary blood and oxygen. This can lead to a gradual weakening of the heart and is something that happens over time, not overnight.

How Would I Know If I Have Low Diastolic Blood Pressure?

Low blood pressure is often overlooked because it is a benign condition. In many patients, it is also asymptomatic, meaning it doesn’t show any symptoms.

But it can become a cause for concern when the pumping force isn’t strong enough to supply vital organs with oxygenated blood, according to the National Library of Medicine. [3]

The most commonly recorded low diastolic blood pressure symptoms include: [4]

  • Weakness
  • Exhaustion
  • Lightheadedness
  • Falls
  • Confusion

When you have low DBP, you may also experience symptoms such as heart palpitations, feet swelling, shortness of breath, or chest pain.

A study published in 2016 found that, in general, people with diastolic blood pressure measuring less than 60 mm of mercury have a 49% higher likelihood of developing heart disease and a 32% higher risk of mortality from any cause. [5]

Experts suggest that in adults with an SBP of 120 mm Hg or higher (which indicates an increased pulse pressure), having a low diastolic blood pressure (DBP) is linked with hidden heart muscle damage and coronary heart disease (CHD) events.

So, when adjusting treatment to target an SBP below 140 mm Hg, it might be important to make sure that the DBP doesn’t drop below 70 mm Hg, especially not below 60 mm Hg. This is to prevent potential risks associated with overly low diastolic blood pressure symptoms. [6]

For people who regularly struggle with low DBP, the Vazopril blood pressure support supplement may be able to help. This natural solution can maintain healthy blood pressure levels the precision-formulated blend is designed to promote optimal blood pressure balance and keep the heart in good health.

Why Is My Diastolic Blood Pressure So Low?

There are many low diastolic blood pressure causes. For example, some medications can lower your DBP more than your SBP, particularly if you are taking a class of drugs known as alpha blockers or central-acting anti-hypertensive agents.

Another factor is age. As we grow older, our blood vessels tend to become somewhat less flexible. This can result in an increase in systolic pressure and a decrease in diastolic pressure.

The elderly are more likely to experience low diastolic blood pressure because they are often using combination drug therapies. And the more medicine a person uses, the greater the risk of side effects.

There are people who naturally have lower blood pressure, and this doesn’t typically lead to any health problems. However, for others, a drop in blood pressure can be linked to issues such as:

Some patients might also suffer from neurally mediated hypotension. This is a health problem where blood pressure decreases after standing for extended periods. Low blood pressure can also be attributed to: [7]

  • Dehydration
  • Pregnancy
  • Bleeding
  • Long periods of bed rest
  • Excessive alcohol consumption

A drop in blood pressure can also occur for certain individuals after eating. The Journal of Geriatric Cardiology reports that this is more common in elderly patients, those dealing with elevated blood pressure, or individuals diagnosed with Parkinson’s disease. [8]

How to Treat Low Diastolic Blood Pressure

While we can’t turn back the clock, one approach is to find ways to help our blood vessels maintain or regain their flexibility.

The treatment will vary based on the low diastolic blood pressure causes. For example, if the medicine you are taking is causing you problems, then your doctor might suggest you adjust or change your prescription.

One highly effective low diastolic blood pressure treatment is reducing your intake of dietary salt. Research has shown a strong connection between salt consumption and the flexibility of our blood vessels. The more salt we consume, the less flexible our vessels become.

Many people tend to consume too much salt. While the ideal salt intake can vary based on age and underlying health conditions, a good general guideline is to aim for less than 4 grams per day, as more than this is typically considered excessive, while less than 1.5 grams per day may be too low.

For healthy individuals, around 3.6 grams of salt per day is often suggested, though this is a topic of ongoing debate.

The hypertension experts at UAB, led by Dr. David Calhoun and Dr. Suzanne Oparil, have conducted extensive research on the molecular-level effects of salt on blood vessels. They’ve found that adding salt to endothelial cells (the thin lining inside blood vessels) in experimental settings leads to almost immediate changes. [9]

These cells become less responsive, which means they become stiffer and lose their elasticity. Interestingly, the stiffening of blood vessels occurs shortly after consuming a meal with a high salt content. So, if your blood pressure is very unstable, you might want to consider your salt intake as one of the possible causes of low diastolic blood pressure.

Supplements may also prove useful. The Vazopril blood pressure support supplement offers a comprehensive approach to maintaining optimal blood pressure levels. Vazopril works to lower LDL levels, safeguarding your heart health in the process. It also has potent antioxidant properties, giving you added defense against heart-related concerns.

Another low diastolic blood pressure treatment is making sure you are adequately hydrated, as drinking more water can amplify the blood volume in the body. Additionally, some individuals find wearing compression stockings helpful to relieve the swelling and pain of varicose veins. [10]

Is There Any Way to Prevent Low Diastolic Blood Pressure Symptoms?

Learning how to boost diastolic blood pressure can be a key aspect of preventing health complications. Here are some practical steps you can take to enhance your well-being and elevate your quality of life.

  • Stay well-hydrated and avoid alcohol. Alcohol has both chronic and acute effects on blood pressure. It can also dehydrate the body. Research shows that if someone consumes a large amount of alcohol (more than 30 grams) within 6 hours, their SBP drops by about 3.5 mmHg, while their DBP drops by about 1.9 mmHg. Their heart rate (HR), on the other hand, increases by about 5.8 beats per minute. The more alcohol you drink, the higher the odds of having low DBP. [11]
  • Consume a balanced and heart-healthy diet. Opt for meals rich in whole grains, fatty fish, lean meats, vegetables, and other high-quality protein sources. Anything that is too processed or greasy can have a negative effect on heart health.

  • Be physically active. If you carry excess weight or lead a sedentary lifestyle, it becomes difficult to keep the heart healthy. Regular physical activity boosts circulation and blood pressure, thus strengthening your heart muscle. [12]

  • Quit smoking. Research shows that cigarette smoking increases the risk of abnormal blood pressure. Smoking leads to the narrowing of blood vessels, which can increase resistance to blood flow. Additionally, it can damage the lining of blood vessels and increase the odds of dehydration. [13]

Don’t wait until low DBP becomes a problem. Take proactive steps in maintaining healthy blood pressure levels by using the Vazopril blood pressure support supplement. With an option such as this, you can take charge of your cardiovascular health and supply the body with the nutrients and vitamins it needs.


What Happens If I Don’t Take Care of My Low Diastolic Blood Pressure?

When your diastolic pressure is low, it means you have reduced pressure in your coronary arteries. This can result in insufficient blood and oxygen supply to your heart. This condition, known as ischemia, can lead to chronic, gradual weakening of the heart. If left untreated, it could potentially culminate in heart failure.

Research has shown that when it comes to cardiovascular risk, systolic blood pressure (SBP) plays a pivotal role. From a physiological standpoint, low diastolic blood pressure (DBP) can potentially have a negative impact on the blood supply to the heart muscle. [14]

This is because, unlike in other parts of the circulatory system, blood flow in the epicardial coronary arteries (i.e., the large coronary arteries surrounding the heart) is sustained during the resting phase between heartbeats.

Anyone can experience diastolic dysfunction. But, you may be more prone to it if you are over the age of 70, don’t exercise regularly, or use tobacco products. Other individuals who may be more prone to low DBP are those with a +30 BMI, coronary artery diseases, metabolic disorders, cardiomyopathy, high blood pressure, or sleep apnea. [15]

Talk to a healthcare expert if you can’t keep your blood pressure stable.

Frequently asked questions

How to boost diastolic blood pressure?

To raise the diastolic pressure, it is best to focus on your diet and nutrition, checking to see if you have any vitamin deficiencies. [16]

For example, vitamin B12 plays a crucial role in supporting the body's production of red blood cells. A deficiency in this vital vitamin can lead to anemia, causing a drop in blood pressure. You can boost your vitamin B12 levels by incorporating foods like eggs, poultry, fatty fish, etc.

Vitamin B9 (folate) is another crucial vitamin that you can get from foods to keep your blood pressure stable. If you are eating too many processed carbs or other products high in carbohydrates, you might want to opt for a low-carb diet. Staying hydrated and consuming caffeine from time to time may also help.

But, before you make any changes to your diet, make sure to talk to a certified specialist, because what works for others may not work for you. So, get a personalized, low diastolic blood pressure treatment plan that can accommodate your particular health problem.

What factors influence low diastolic blood pressure?

For older patients, it can be good to keep diastolic blood pressure (DBP) within the 60 to 90 mm Hg range. Factors that can affect low DBP include inadequate fluid intake, long periods of bed rest, hormonal imbalances, nutrient deficiencies, alcohol consumption, allergic reactions, and prolonged standing.

For example, when an older patient stands for too long, blood can start to accumulate in the legs. This means there has been less blood returning to the heart, which can contribute to a drop in diastolic blood pressure.

Prolonged standing can also exacerbate orthostatic hypotension, a condition where blood pressure drops significantly when transitioning from lying down or sitting to standing. This can result in both low systolic and diastolic blood pressure. That’s why someelderly people may feel dizzy after standing for too long. [17]

Should I be worried if I have low diastolic blood pressure?

When blood pressure plummets to dangerously low levels, it can result in shock. This is a condition where there's inadequate blood flow in the body.

The signs of shock are:

  • Rapid breathing - When a person is in shock, their body may respond by increasing the rate at which they breathe. This is an attempt to get more oxygen into the body, as shock can lead to decreased oxygen levels in the tissues.
  • Weak or rapid pulse - The pulse may become weaker because the heart is struggling to maintain blood flow. At the same time, the heart rate may increase as the body tries to compensate for the drop in blood pressure.
  • Cold, sweaty skin - Shock can cause the blood vessels in the skin to constrict or the body to release stress hormones.
  • Blue skin - In severe cases of shock, especially when oxygen levels are critically low, the skin may take on a bluish tint.

If you encounter these warning signs, seek medical help immediately.

Is it possible for low diastolic blood pressure to cause a stroke?

According to a study from 2021, patients with systolic blood pressure below 120 mm Hg, diastolic blood pressure below 60 mm Hg, and pulse pressure of at least 90 mm Hg were more likely to die from stroke compared to those with more standard blood pressure and pulse readings. [18]

When diastolic blood pressure is too low, it can lead to inadequate blood flow to the brain. This reduced blood flow may not provide sufficient oxygen and nutrients to brain cells, which can increase the risk of stroke.

Additionally, low diastolic blood pressure can result in decreased perfusion (blood supply) to the brain, potentially leading to ischemia (a lack of blood flow) in certain areas of the brain. That’s why many doctors suggest you try and keep your blood pressure as stable as possible. Talk to your doctor for personalized guidance and blood pressure monitoring.


Many things shape our cardiovascular system, including diastolic blood pressure. When we delve into the intricacies of low diastolic blood pressure, we need to understand that there are many factors that can cause this problem.

Because this is a complex condition, there is not a one-size-fits-all treatment. Your dietary preferences, lifestyle choices, and exercise routine could all affect your DBP so it is best to consult with a specialist and find a treatment that will keep your heart in good health. To redress nutrient deficiencies that might be contributing to the problem, you may consider using the high-quality, all-natural blood pressure support supplement Vazopril.
