Blood pressure varies from one person to another. A drop as little as 20 mmHg, can cause problems for some people. There are different types and causes of low blood pressure. Severe hypotension can be caused by sudden loss of blood (shock), severe infection, heart attack, or severe allergic reaction (anaphylaxis).

Now the doctors needed to figure out why. A quick review of the blood-pressure medications she took found a likely culprit. Doxazosin could cause blood pressure to drop rapidly, often after a change in position — a condition known as orthostatic (from the Greek for “standing upright”) hypotension.

A change of just 20 mm Hg — a drop from 110 systolic to 90 mm Hg systolic, for example — can cause dizziness and fainting when the brain fails to receive enough blood. And big drops, such as those caused by uncontrolled bleeding, severe infections or allergic reactions, can be life-threatening.
