Familial Chylomicronemia Syndrome (abbreviated FCS) is a condition of very high triglycerides (a type of fat) in the blood which come from the diet. The enzyme that breaks down triglycerides from the diet is absent or does not work well, causing triglyceride levels in the blood to build up.
High triglycerides in the blood can cause episodes of pancreatitis, a painful and potentially life-threatening inflammation of the pancreas.
Although FCS is a genetic (inherited) condition, genetic testing is not required. Symptoms can vary and the age at which symptoms occur may vary. An individual can often have severe symptoms before FCS is ever diagnosed. Several identifiable symptoms can include:
The fact that high levels of triglycerides can be associated with other health issues, such as alcohol consumption, unmanaged diabetes, or various medications, combined with the rareness of the disease, FCS is often misdiagnosed or remains undiagnosed. It is extremely important to connect with a Lipid Specialist who is trained in managing blood lipids if you have any questions or concerns.
There are currently no FDA approved therapies for the treatment of FCS.
Most patients take steps to reduce their risk of pancreatitis through lifestyle modifications including strictly limiting fat intake.
Diet & Lifestyle |
When you have FCS, the enzyme that breaks down triglycerides from the diet is absent or does not work well, causing triglyceride levels in the blood to build up. You are unable to remove these fats from your blood and you must avoid eating foods high in fat. A buildup of triglycerides in the blood can cause severe abdominal pain due to pancreatitis (inflammation of the pancreas). Sticking to a low-to-no-fat diet is essential to reduce the pain and pancreatitis risk. Download the FCS Diet Tearsheet for more helpful tips. |

Discuss the need for genetic testing with your healthcare provider. It is not necessary for most. If you have a genetic test, the result may help determine the best treatment and if any of your family members should be tested.
