Histamine intolerance (HIT)
The inability of the body to properly break down histamine, which leads to its excessive accumulation and manifestations.
Histamine intolerance (HIT) is not a classic allergy, but a condition where the body cannot efficiently break down histamine from food or from its own sources. This leads to its excessive accumulation in the body and triggers various non-specific symptoms such as digestive problems, skin problems, headaches or breathing difficulties.
