FH, or Familial Hypercholesterolemia, is a genetic disorder that results in high levels of cholesterol in the blood. It is caused by mutations in genes responsible for removing low-density lipoprotein (LDL) cholesterol from the bloodstream. Individuals with FH are at a higher risk of developing cardiovascular diseases at an early age. There are two main types of FH: Heterozygous FH, where one copy of the mutated gene is inherited, and Homozygous FH, where both copies are affected. Early diagnosis and treatment, including lifestyle changes and medications, are crucial for managing cholesterol levels and reducing health risks associated with this condition.
