WHAT IS SM?

Systemic mastocytosis (SM) is a rare condition where abnormal mast cells (a type of white blood cell) build up in different parts of the body, resulting in a variety of symptoms. It is estimated that approximately 32,000 people in the U.S. (or 0.01% of the population) may be living with SM.1

COULD YOUR SYMPTOMS BE ADDING UP TO SMthing?

Multiple symptoms across different parts of the body could be connected, even if they seem to be unrelated. From skin-related symptoms such as rashes, flushing, and swelling, to symptoms like nausea, cramping, pain, fatigue, and more—your symptoms could be adding up to something.

LIVING WITH SM

Not everyone's experience with SM is the same — it seems no two people have exactly the same symptoms or triggers. They may not even see the same kinds of doctors. However, people with SM may find more similarities than differences when they hear the stories of others.
