What Is FCS?

Familial Chylomicronemia Syndrome icon

FCS is a rare disease that impacts what you can eat and how you feel.1,2

Familial Chylomicronemia Syndrome icon

When you have FCS, your body has a problem breaking down triglycerides, a kind of fat that comes from the food you eat and is stored in large triglyceride-carrying particles called chylomicrons.2,3Chylomicrons transport dietary fat from the small intestine to other parts of the body.3

Familial Chylomicronemia Syndrome icon

Lipoprotein lipase (LPL) is a protein that normally works to break down triglycerides from your blood. In people with FCS, LPL doesn’t work properly.1,2

Familial Chylomicronemia Syndrome icon

Triglycerides build up in your blood instead of breaking down, leading to very high triglyceride levels.1,2
