Common Symptoms Of Mastocytosis

Anaphylaxis

Individuals affected by mastocytosis are more likely to have a severe allergic reaction because of the large number of mast cells in their bloodstream. When the mast cells are triggered by an allergen, they release large amounts of histamine in the patient's blood. This massive release of histamine is known to produce severe and life-threatening symptoms, including extremely itchy skin, abdominal pain, narrowing of the airways, wheezing, problems with breathing, dizziness, lightheadedness, swollen eyes, swollen lips, swollen feet, clammy skin, loss of consciousness, confusion, anxiety, rapid heartbeat, raised red rash, and swollen hands. Certain allergens are more common as triggers for anaphylactic episodes in mastocytosis patients. While food-related and drug-related reactions are less common, those caused by bee and wasp stings tend to be more prevalent.
