Histamine intolerance is a presumed set of adverse reactions (such as flush, itching, rhinitis, etc.) to ingested histamine in food. The mainstream theory accepts that there may exist adverse reactions to ingested histamine, but does not recognize histamine intolerance as a separate medical condition that can be diagnosed. [1]
Mast cell activation syndrome (MCAS) is a term referring to one of two types of mast cell activation disorder (MCAD); the other type is idiopathic MCAD. [1] MCAS is an immunological condition in which mast cells, a type of white blood cell, inappropriately and excessively release chemical mediators, such as histamine, resulting in a range of chronic symptoms, sometimes including anaphylaxis or ...
“Histamine is released in the body and enters the gastrointestinal tract, which can cause gas, bloating, nausea, stomach pains and diarrhea.” ... Treating allergy symptoms with over-the ...
Symptoms are thought to be the result of histamine being released by mast cells on the surface of the skin. Despite the lack of antigens, histamine causes the skin to swell in affected areas. If the membrane that surrounds the mast cells is too weak, it will easily and rapidly break down under physical pressure, which then causes an allergic ...

Food intolerance is a detrimental reaction, often delayed, to a food, beverage, food additive, or compound found in foods that produces symptoms in one or more body organs and systems, but generally refers to reactions other than food allergy. Food hypersensitivity is used to refer broadly to both food intolerances and food allergies.
Histamine is an organic compound that primarily functions in service of the human body's immune responses as well as for the regulation of many physiological functions. [1] Since their discovery in 1910, [ 2 ] histamines have been known to trigger inflammatory responses such as itching as part of an immune response to foreign pathogens; for ...
DAO levels in the blood circulation increase vastly in pregnant women suggesting a protective mechanism against adverse histamine. [12] Histamine is a potent vasodilator and can cause uterine contractions, which can lead to premature labor. DAO in the placenta breaks down histamine to prevent its accumulation and maintain a healthy pregnancy.
