Histamine Intolerance and Pregnancy

As we now know from the blog post on histamine and female reproductive hormones, there is a direct impact on histamine levels when they fluctuate. During pregnancy there are dramatic changes not only to a woman’s body but also to how their hormones are functioning. One area that is not commonly known is the changes in gut health during pregnancy which can impair the functioning of the DAO enzyme which breaks down histamine.

Histamine Intolerance

Because of increasing oestrogen levels, impaired gut function, potential nutrient depletion due to fetal development, likely increased stress and dietary factors pregnant women can develop histamine intolerance due to increased histamine levels in the bloodstream.

Histamine Intolerance Symptoms

Symptoms of histamine intolerance include headaches, migraines, flushing, itching, and gastrointestinal disturbances.

How to manage Histamine Intolerance

Managing histamine focuses on gut support to promote histamine breakdwon via the DAO enzyme, supporting oestrogen clearance via the liver, reducing high histamine foods and reducing stress levels.
