There are certain conditions that can cause long periods of hypotension that can become dangerous if left untreated. These conditions include pregnancy. This is because, during pregnancy, there is an increase in demand for blood for both the growing foetus and the mother. Low blood pressure is a common phenomenon during the first 24 weeks of pregnancy.

Other causes can be heart conditions such as slow heart rate, problems with heart valves, heart attack and heart failure leading to impaired circulation. Similarly, a decrease in blood volumes such as loss of blood from major trauma, dehydration or severe internal bleeding can cause a severe drop in blood pressure. Few endocrine disorders, such as diabetes, adrenal insufficiency, and thyroid disease can also be a cause. 

The American Heart Association stated that certain drugs can cause low blood pressure. These drugs include diuretics and other drugs that are used to treat hypertension, heart medications such as beta blockers, drugs for Parkinson’s disease, tricyclic antidepressants, erectile dysfunction drugs, etc.

Other causes include prolonged bed rest, blood infections, autonomic dysfunction, damage to the nerves that control some bodily functions, severe infection (septic shock), allergic reaction (anaphylaxis), nutritional deficiencies such as vitamin B-12 and folic acid deficiencies, etc.
