How Histamine Intolerance Occurs
Excessively high histamine results in a wide array of symptoms and can mimic or contribute to other health problems. Histamine intolerance is often overlooked and not addressed leaving people with chronic symptoms and no answers.
Mast Cell Activation Syndrome (MCAS)
A subset of Histamine Intolerance is Mast Cell Activation Syndrome where the mast cells containing histamine release abnormally large amounts of histamine into the rest of the body.
Managing Histamine Effects
Avoiding foods that are high in histamine and taking antihistamine drugs (Claritin, Allergra, Zrytec) to block histamine receptors can be a useful. Neither method solves the issues of excessive release and inadequate breakdown of histamine.
Histamine Intolerance Symptoms
Many of the symptoms mimic allergic reaction. Other symptoms can include headache, eye and sinus symptoms, irregular or rapid heart rate, rash, itching, flushing, gastrointestinal (nausea, vomiting, diarrhea, abdominal pain, bloating, malabsorption), low blood pressure, dizziness or fainting, muscle, joint, and bone pain, fatigue, anxiety, and impaired focus and memory (foggy-headedness).
