FH Awareness Day is observed worldwide every September 24. Established in 2012 by the Family Heart Foundation, the day aims to educate the public about familial hypercholesterolemia (FH), a genetic disorder that results in high cholesterol levels from birth and increases the risk of early cardiovascular disease. The observance encourages individuals with a family history of high cholesterol or cardiovascular issues to get tested for FH. It highlights the difference between high cholesterol caused by genetics and that resulting from lifestyle factors. FH is often undiagnosed, with 70-85% of affected individuals remaining untreated, despite being easily diagnosed through blood tests. The day serves as a reminder of the importance of awareness and early intervention in managing this condition.
