Silent Killer: High Cholesterol's Hidden Danger

High cholesterol often goes unnoticed, silently damaging blood vessels until severe complications arise, such as heart attacks or strokes. This condition, sometimes called a silent killer, is a significant factor in one-third of global heart disease cases. In India, approximately 25-30% of urban adults are affected, and this prevalence is growing due to changing lifestyles.

Many people are unaware of their condition as it typically presents no symptoms. This lack of immediate feedback, unlike conditions like diabetes, can lead to delayed diagnosis. While genetics play a role, lifestyle factors including diet, stress, sleep, and smoking are major contributors. Early detection via blood tests, ideally starting in the early 20s for a baseline, and regular check-ups, especially for those over 40 or with risk factors, are vital.

Managing high cholesterol involves significant lifestyle changes, such as reducing saturated fat intake and increasing physical activity. However, for some, especially those with very high levels or genetic predispositions like familial hypercholesterolemia, medication may be necessary. Combining lifestyle adjustments with prescribed treatments offers the best outcomes. Atherosclerosis, the hardening and narrowing of arteries due to cholesterol buildup, can lead to reduced blood flow and increased risk of cardiac events.
