Persistent fasting triglycerides >880 mg/dL? It could be familial chylomicronemia syndrome (FCS).16,12
Acute pancreatitis.
Recurrent, unexplained abdominal pain.
Eruptive xanthomas.
These are just a few signs of FCS.12
Familial chylomicronemia syndrome (FCS) is an underdiagnosed genetic form of severe hypertriglyceridemia (sHTG) characterized by fasting chylomicronemia, extremely high triglyceride levels (≥880 mg/dL),12 and typically resistance to traditional TG-lowering medication.16
Despite the genetic nature of FCS, its recessive inheritance pattern means people with FCS have no family history of the condition.14
An estimated 1-13 people per million
have FCS.45, 46,47
Healthcare professionals may find the clinical features of FCS challenging to recognize and diagnose. Diagnostic delays can leave people with FCS at a very high risk for severe complications, such as acute pancreatitis (AP) and hepatosplenomegaly.34 For AP alone, they have a 360-fold elevated risk compared with the general population.14
In addition, FCS dramatically impairs quality of life, well-being, social relationships, and ability to maintain employment.22
