Low diastolic blood pressure, also known as hypotension, can be caused by various factors. Some common causes include:
- Medications : Certain medications, such as alpha-blockers or central-acting anti-hypertensive agents, can lower diastolic blood pressure more than systolic blood pressure
- Aging : As people age, their blood vessels may become stiffer, which can lead to a drop in diastolic blood pressure
- Dehydration : Conditions like fever, vomiting, severe diarrhea, overuse of diuretics, and strenuous exercise can cause dehydration, which can lead to a drop in blood pressure
- Orthostatic hypotension : This occurs when there is a sudden drop in blood pressure when standing from a sitting position or after lying down. It can be caused by dehydration, long-term bed rest, pregnancy, certain medical conditions, and some medications
- Postprandial hypotension : This drop in blood pressure occurs 1 to 2 hours after eating and is most likely to affect older adults
- Pregnancy : Changes during pregnancy can cause blood vessels to expand rapidly, leading to a drop in blood pressure
- Heart and heart valve conditions : A heart attack, heart failure, heart valve disease, and an extremely low heart rate (bradycardia) can cause low blood pressure
- Hormone-related conditions : Hormonal imbalances can also contribute to low diastolic blood pressure
Low diastolic blood pressure can be a concern because it may cause symptoms such as dizziness, fainting, and tiredness, and can lead to serious injuries, heart tissue damage, and heart disease
. It is essential to consult a doctor if you have concerns about your blood pressure or experience symptoms related to low diastolic blood pressure.
