What Is Histamine Intolerance? - South Arkansas Sun

Everyone has histamine in their bodies. You’ve probably heard of antihistamines for allergic reactions. Made from the precursor amino acid, histidine

It has many roles in the body- – Contracts smooth muscles (like for breathing) – Dilates blood vessels – Influences blood pressure

Histamine intolerance (HIT) occurs when the body cannot effectively metabolise and destroy histamine. Symptoms are caused by a buildup, not an allergy or food intolerance.

Histamine intolerance symptoms appear 30 to 72 hours after eating particular meals. People can suffer symptoms from one, multiple, or all categories.

How does a person get to the point that their body can no longer metabolize histamine? There are a few different causes of HIT to explore.

HMNT breaks down histamine throughout the body. If you have the MTHFR mutation, you may struggle to break down histamine unless you supplement with a methylated vitamin B.

The DAO enzyme primarily breaks down histamine in the intestines, kidneys, and colon, keeping it from leaking into the bloodstream.

In order to get a HIT diagnosis, your doctor must rule out the following: – Skin prick food allergy test – Tryptase levels for systemic mastocytosis – DAO inhibiting drugs
