Cholesterol problems are often seen as an issue of midlife, but the American Heart Association (AHA) stresses that high cholesterol can begin to affect health much earlier. Adults aged 20 and above are encouraged to monitor cholesterol levels every four to six years. Those with diabetes, high blood pressure, or a family history of heart disease may need more frequent checks.

Experts also recommend that cholesterol screening start in childhood. Healthy children should be checked once between ages 9 and 11, and again between 17 and 21. For kids with a strong family history of heart disease or very high cholesterol, testing can begin as early as age 2.

Inherited conditions like familial hypercholesterolemia can silently raise cholesterol from birth, affecting about 1 in 200 adults. Identifying it early, along with lifestyle measures such as balanced diet, regular exercise, maintaining a healthy weight, and avoiding smoking, can significantly lower risks.

Since cholesterol begins damaging arteries at a young age, waiting until middle age for a check-up can be dangerous. The AHA’s message is clear: start early, test regularly, and make heart-healthy choices to safeguard long-term health.
