What could cause low blood pressure?
Q. My blood pressure stays low. Sometimes it drops so low, it causes dizziness and weakness. What causes this?
A. Of the possible causes of low blood pressure, two are at the top of my list. First, I would review your medications. Drugs prescribed to treat high blood pressure and heart disease are the ones that most often cause this side effect. Reducing the dose with your doctor's approval may be all you need.
