Hi,
Welcome to JA and thanks for this question. Im sorry to hear about your symptoms. Now there are multiple causes for a low blood pressure. The commonest cause for low blood pressure is dehydration or even problems which cause loss of fluid such as diarrhea or vomiting. This would usually be the cause in most patients. The second commonest cause is actually pooling of blood in the lower limbs which can occur in patients who have swollen veins in the lower legs or vascular insufficiency.

Now apart from this there are various causes which can cause a lower blood pressure,

Heart conditions. Some heart conditions that can lead to low blood pressure include extremely low heart rate (bradycardia), heart valve problems, heart attack and heart failure.

Endocrine problems. Thyroid conditions such as parathyroid disease, adrenal insufficiency (Addison's disease), low blood sugar (hypoglycemia)

Lack of nutrients in your diet. A lack of the vitamins B-12 and folate can keep your body from producing enough red blood cells (anemia), causing low blood pressure.

Medications. Some medications can cause low blood pressure, including:

  • Water pills (diuretics), such as furosemide (Lasix) and hydrochlorothiazide (Maxzide, Microzide, others)
  • Alpha blockers, such as prazosin (Minipress)
  • Beta blockers, such as atenolol (Tenormin) and propranolol (Inderal, Innopran XL, others)

In short there are several causes for this to occur, if you are experiencing a lower blood pressure of less than 90/60 repeatedly then you should be investigated for the above causes and also for autonomic dysfunction which can lead to this sort of problem.

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.
