World Heart Day 2025 is a reminder that heart health is deeply linked to cholesterol levels. Experts warn that uncontrolled cholesterol, particularly LDL (bad cholesterol), can silently harm the body and increase the chances of heart attacks and strokes. According to the World Heart Federation, nearly 80% of premature cardiovascular deaths can be prevented with early intervention and lifestyle management.
How High Cholesterol Affects the Heart
If cholesterol levels remain elevated and untreated, they can damage the cardiovascular system. Dr. Nagendra Boopathy S, Professor of Cardiology at Sri Ramachandra Institute of Higher Education and Research, explained that high LDL cholesterol promotes plaque formation and rupture, which leads to atherosclerosis. This condition increases the risk of heart attack, ischemic stroke, and peripheral artery disease.
Beyond the heart, cholesterol can also affect the brain, kidneys, and limbs, especially if patients already have other health conditions.
Cholesterol Risks in Indian Population
Dr. Boopathy highlighted a unique pattern among Indians called atherogenic dyslipidaemia. This involves raised triglycerides, low HDL (good cholesterol), and small dense LDL particles, which increases the chances of early coronary artery disease, even if LDL levels are not very high. Therefore, full lipid profile screening is critical in the Indian context.
How to Manage Cholesterol Effectively
Cardiologists emphasize that lifestyle plays a vital role in keeping cholesterol under control. Dr. Zakia Khan, Cardiologist at Fortis Hospital, Mumbai, advised a balanced diet, regular exercise, and maintaining a healthy weight.
She explained, “A diet rich in vegetables, fruits, legumes, whole grains, millets, nuts, and minimal refined carbohydrates improves lipid levels and reduces cardiovascular risks. Even modest weight loss of 5–10% can significantly reduce LDL cholesterol.”
Exercise should be treated as medicine and tailored to individual capacity. Importantly, regular cholesterol screenings are essential because problems often develop without noticeable symptoms. For high-risk patients, LDL levels should ideally be less than 70 mg/dL, which often requires both lifestyle changes and medical treatment.
Conclusion
Uncontrolled cholesterol is a silent threat that can lead to irreversible heart damage. By combining dietary changes, weight management, physical activity, and regular screenings, individuals can lower their risks and protect their heart health.
