How to Deal with Low Diastolic Blood Pressure?


Low diastolic blood pressure can be a very concerning situation to be in for many individuals. We see a lot of people talking about high blood pressure but persistent lower diastolic blood pressure is equally concerning as it can have adverse effects on health and overall well being. In this blog, we will discuss the symptoms to see if your diastolic blood pressure is low, the causes of low diastolic pressure and how to manage it. 


What is Diastolic Blood Pressure?

Blood pressure is the force exerted by the circulating blood on the walls of blood vessels. So the blood pressure consists of two numbers; one is systolic pressure and other is diastolic pressure. Systolic pressure represents the pressure when heart contracts while diastolic pressure is the one when heart is at rest between beats. Blood pressure is measured in millimeters of mercury (mm of Hg) and normal blood pressure is 120/80 mm of Hg. When we are talking about low diastolic blood pressure, it is somewhere below 60 mm of Hg.

Symptoms of Low Diastolic Blood Pressure

  1. Sudden blood pressure drop, especially when standing can cause imbalance and disorientation leading to dizziness or lightheadedness. 

  2. Loss of consciousness due to inadequate blood flow to the brain may cause fainting. 

  3. Persistent tiredness from insufficient oxygen and nutrients delivery to tissues.

  4. Blurred vision is another symptom. Reduced blood flow to the eyes, causing unclear vision and visual disturbances.

  5. Difficulty concentrating due to decreased blood flow to the brain.

  6. You may experience cold or clammy skin. Peripheral vasoconstriction leads to chilly, damp skin sensation, indicating poor circulation.


Causes of Low Diastolic Blood Pressure

There are several factors that can contribute to low diastolic blood pressure. Some of them are;


Not drinking enough fluids can lead to decrease in blood volume that can cause lower blood pressure readings. 



Certain medications, such as alpha-blockers, beta-blockers, and diuretics, can lower blood pressure, including diastolic pressure.


Heart conditions

Conditions such as bradycardia (slow heart rate), heart valve problems, and heart failure can also lead to lower diastolic blood pressure.


Endocrine disorders

Disorders such as adrenal insufficiency or hypothyroidism can affect blood pressure regulation.


Nutritional deficiencies

Lower blood pressure can also be a sign of certain nutritional deficiencies such as vitamin B12, folate and iron.

Managing Low Diastolic Blood Pressure

It is important to consult with a healthcare professional if you are experiencing symptoms of low diastolic blood pressure. However, certain strategies and lifestyle changes can help you better manage your low diastolic blood pressure. 

  1. Drink an adequate amount of fluids throughout the day to maintain blood volume and prevent dehydration.

  2. In some cases, increasing salt intake slightly may help raise blood pressure.

  3. Compression stockings can help improve blood circulation and prevent blood from pooling in the legs, which can contribute to low blood pressure.

  4. Consuming smaller, more frequent meals throughout the day can help prevent drops in blood pressure after eating.

  5. Regular physical activity can help improve cardiovascular health and blood pressure regulation. However, avoid intense exercise sessions in hot environments, as this can lead to dehydration and further lower blood pressure.

  6. Keep track of your blood pressure readings at home and report any significant changes or symptoms to your healthcare provider.



In conclusion, lower diastolic blood pressure may not be as alarming as higher blood pressure but it can be concerning if it is persistent. Knowing the symptoms and causes, may lead to better management.


Diastolic Blood Pressure



1. Can stress affect diastolic blood pressure?

Yes, stress can impact blood pressure, including diastolic pressure. During times of stress, the body releases hormones like adrenaline, which can temporarily raise blood pressure. Chronic stress can contribute to long-term blood pressure issues, including low diastolic blood pressure in some cases.


2. Can low diastolic blood pressure be a sign of an underlying health condition?

Yes, low diastolic blood pressure can sometimes indicate underlying health issues such as heart problems (like heart failure or bradycardia), hormonal imbalances, dehydration, or nutritional deficiencies. It's essential to consult with a healthcare professional for proper evaluation and diagnosis. 


3. Should pregnant women be concerned about low diastolic blood pressure?

Low diastolic blood pressure during pregnancy can sometimes occur due to hormonal changes and increased blood flow to the uterus. While mild decreases in diastolic blood pressure are common during pregnancy, significant or persistent low blood pressure should be discussed with a healthcare provider to rule out any potential complications.


4. Can low diastolic blood pressure increase the risk of falls?

Yes, low diastolic blood pressure can increase the risk of falls, especially in older adults, due to symptoms like dizziness or lightheadedness. It's important for individuals experiencing low diastolic blood pressure to be cautious when standing up from sitting or lying down to prevent falls and related injuries.
