Familial Chylomicronaemia Syndrome (FCS) is the name for a group of rare genetic disorders that cause very high levels of triglycerides in the blood.
Triglycerides are a kind of fat, and high levels of triglycerides can lead to serious health problems in the long term, including pancreatitis and diabetes. With a very low fat diet, you can help to avoid these problems.
You might also hear FCS called Lipoprotein Lipase Deficiency (LPLD) – which is the most common type of FCS – or chylomicronaemia.
FCS is very rare, around one to two in a million people have it.
