Stress is one of the most common triggers of systemic mastocytosis (SM) symptoms.
Emotional reactions such as stress and anxiety stimulate mast cells and cause them to release greater levels of histamineHistamine A chemical released by mast cells when they are activated. Histamine causes many of the allergy-type symptoms in mastocytosis, including flushing, itching and hives. and other chemicals into the bloodstream.
What is SM?
Systemic mastocytosisMastocytosis Rare disease caused by the buildup of mast cells. Cutaneous mastocytosis primarily affects the skin and is more common in children, while systemic mastocytosis affects internal organs and is more common in adults. (SM) is a rare hematological disease characterized by mast cells that are overactive and accumulate in different parts of the body such as the bone marrow, liver, spleen, gastrointestinal tract and lymph nodes.
Learning to manage stress levels with SM is key to avoiding symptom episodes and enjoying a better quality of life.
How stress affects SM symptoms
In SM, mast cells proliferate uncontrollably and build up in the connective tissue and internal organs.

Emotional, psychological or mental stress can trigger an allergic reaction, as can physical exertion, sudden changes in temperature, certain foods and medication, alcohol, pollen, insect stings or skin friction. The reaction releases histamine, cytokine and leukotrienes into the bloodstream.
A mind-body connection is evident in the effect of stress on SM symptoms. Stress stimulates the secretion of corticotropin-releasing hormone (CRH) in the hypothalamus as a way of controlling the stress response.
In SM patients, CRH can stimulate mast cell activationMast cell activation Describes when mast cells release histamine and other mediators into the blood stream in response to an allergen or other trigger. This leads to symptoms like fatigue, rash and, in severe cases, anaphylaxis., causing an inflammatory response. Greater levels of CRH have been found in people with SM, leading to a more intense allergic reaction.
Associated symptoms of stress-related mast cell activation include skin irritation, itching, hives or flushing; gut-related issues such as cramps, nausea or vomiting; shortness of breath; heightened anxiety or fatigue; and bone or joint pain. AnaphylaxisAnaphylaxis A severe allergic reaction that can turn fatal without treatment. Patients with SM are at a higher risk of developing anaphylaxis. is the most serious symptom and can be life-threatening.
Ways to manage stress

By lowering your stress levels in the following ways, you can avoid activating mast cells and triggering symptoms.
- Monitor your stress levels: Learn your stress triggers and avoid them. Understand how to lower your stress levels before they become critical.
- Get physically activity: Light regular physical activity is a known mood booster and stress reliever.
