Low Blood Pressure

What causes low blood pressure

Hypotension is a condition which will develop once the blood pressure drops in a drastic manner because of some reasons. As previously mentioned, blood pressure of 90/60 mmHg is considered to be a borderline low blood pressure. Alternatively, when the blood pressure decreases further to 60/40 mmHg or 50/30 mmHg, then it could be an indication of danger. Take note that this condition will have negative effects on vital organs of the body such as the kidneys, heart and the brain. Also, it must be noted that several common effects of hypotension include headaches, kidney problems, shock, fainting as well as heart attack.

Low Blood Pressure (Hypotension) Causes

If the volume of blood is affected in several ways, it will have an effect on the blood pressure resulting to low blood pressure. Secondly, hypotension can also be caused by use of medications and some disorders and diseases. Listed below are the prominent causes.


For some people especially women, dehydration makes the blood pressure lower. Also, hypotension is possible in severe cases of dehydration as the decrease in the volume of blood will cause a drop in blood pressure.

Blood Loss

One of the most common causes of low blood pressure is blood loss. Such loss of blood could be due to diseases such as diverticulitis and ulcers, external or internal bleeding, injury and many more and can lead to decrease in blood pressure.


This is also considered to be one of the primary reasons for reduced blood pressure among women. Since the circulatory system of a woman will expand during the pregnancy period, there is a possibility that blood pressure will drop leading to hypotension. This condition has to be given immediate treatment.


Among the major low diastolic pressure causes is the use of medications such as diuretics and for high blood pressure like beta blockers. Bear in mind that hypotension can also occur as one of the serious side effects of some medications such as Parkinson’s disease, antidepressants, drugs for the treatment of erectile dysfunction, alpha blockers and many more.

Diseases and Disorders

Low blood pressure can also be an indication of some diseases and disorders such as heart failure, hypothyroidism, diabetes, Addison’s disease, endocrine problems, low blood sugar and a lot more.
