A concise study of Histamine Intolerance

What is histamine intolerance?

Histamine is a chemical responsible for certain functions in the human body. The functions of histamine include communicating messages to the brain and releasing stomach acid to help in digestion. After some injury or any allergic reaction, histamine releases as a part of the immune response.

An abundance of this functional chemical or the phase where it cannot break down properly; it goes on to affect the normal body functions. Histamine Intolerance does not mean sensitivity to histamine, but indicates the fact that the body is producing excessive histamine.

What are the symptoms?

Histamine Intolerance may seem to have similarity with that of allergic reactions, but in reality, they are different in characteristics. The symptoms vary from person to person and depend on the seriousness of the condition.

A variety of symptoms can be seen in a person with histamine intolerance, making it difficult to determine the source.

What are the causes?

Diamine Oxide(DAO) and Histamine N-methyltransferase (HNMT) are the enzymes responsible for the metabolism of histamine that the body receives from food. The incapability of HNMT and DAO to break the histamine causes intolerance in the body.

Many food and drinks are rich in histamine. Certain factors interfere with the way DAO and HNMT break down histamine. Certain medicines disturb the procedure, including heart medicines, antibiotics, pain medication, gastrointestinal medicines, antipsychotics, antidepressants, a muscle relaxant. Apart from these, painkillers like Aspirin, Indocin, Voltaire, Naproxen blocks the path.

Indigestion of food causes bacterial growth, which is another contributing factor. The bacterial growth happens when food is not digested properly, causing overproduction of histamine. Overproduction of histamine becomes difficult to break down, which ultimately causes the irritation.

Deficiency in Vitamin B-6, Vitamin C, copper or Zinc, liver conditions, compromise with the gut lining due to injuries or intestinal condition, alcohol, chronic stressed some of the other reasons that cause histamine intolerance.

The amount of histamine accumulated in the bloodstreams is directly proportional to the allergic response of the person.
