Acute intermittent porphyria


What is acute intermittent porphyria?

Acute intermittent porphyria (AIP) is a condition that can cause sudden, severe attacks of stomach pain that may last for a days to weeks. It is called a 'porphyria' because substances called porphyrins build up in the body and can cause the symptoms. Porphyrins are normally used by the body to help cells use oxygen. In AIP, people may also experience mental changes in attacks of acute intermittent porphyria that can include insomnia or difficulty sleeping, anxiety, depression, hallucinations, confusion, paranoia, and amnesia or memory loss.

To understand more about AIP from someone who has the condition, watch this video from the American Porphyria Foundation.
