Overview

Hypotension could be due to hormonal changes, medication side effects, anemia, heart or endocrine problems or caused by widening of blood vessels and low blood volume.

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.
