Histamine intolerance: symptoms

Histamine intolerance symptoms are very diverse. Some patients only show individual complaints (such as redness with itching). Others, on the other hand, have histaminosis with symptoms in several parts of the body. This is because the most diverse cells and organs have docking sites (receptors) for histamine. These include, for example, smooth muscle cells (in the stomach and intestinal wall, in the bronchi and uterus, in the blood vessel walls, etc.), glandular cells, nerve cells and cells of the immune system (such as mast cells).

Histamine mediates its action by binding to these receptors. With a high amount of histamine, the receptors are activated nonstop. Depending on where in the body they are, this results in sensitive people a variety of histamine intolerance symptoms.

Histamine intolerance symptoms: skin

Histamine can activate so-called mast cells in the skin. These then release allergenic ingredients that can cause various skin symptoms:

  • urticaria (Hives): It is characterized by small, fleeting swellings of the skin (wheals), which usually stand together beetartig. The skin usually appears red or white with a red border at the affected areas. The wheals may appear distributed throughout the body. They usually disappear after 24 hours. As long as the trigger of hives but continues to exist, can always form new wheals.
  • Itching: The substances released from the mast cells trigger not only urticaria but also a massive itching. Especially the skin over the wheals is very irritated. Unlike other itchy skin diseases, however, wheals are not scratched, just rubbed and pressed.

Histamine intolerance symptoms of the skin also show in an increased blood circulation: histamine leads to a release of nitric oxide, which broadens the blood vessels. This allows more blood to flow through. This causes the affected Skin areas reddened and warmed, If this phenomenon occurs in the face, it is also called flush designated.

Histamine intolerance symptoms: brain

Also in the brain, histamine via the release of nitric oxide can cause the blood vessels to dilate. If this happens in the arteries of the meninges, headaches can occur. This mechanism is also discussed in migraine.

Other potential symptoms of histamine intolerance that may be from the head include dizziness, nausea, and vomiting. Some patients also report decreased attention and fatigue.
