High cholesterol in India: As studies suggest 25–30% of urban adults have lipid disorders, doctor explains how it can be identified

High cholesterol doesn’t announce itself. No pain. No fever. No bad days that force you to stop and think. And that’s exactly why it’s dangerous. You can walk around for years feeling perfectly fine while damage quietly builds up inside your blood vessels. By the time something finally goes wrong, it’s often sudden and life-changing. "High cholesterol is often referred to as a silent condition because it usually does not cause noticeable symptoms until complications develop," Dr. K. Seshi Kiran, Senior Consultant General Physician, Yashoda Hospitals, Hyderabad told TOI Health. Cholesterol itself isn’t the villain. Your body actually needs it to build cells and make hormones. The trouble starts when there’s too much of the “bad” kind, LDL cholesterol, floating around in your blood. It sticks to artery walls, slowly narrowing them. Blood flow drops. The heart has to work harder. And one day, without much warning, there’s a heart attack or a stroke. Globally, high cholesterol is linked to about one third of heart disease cases. Heart disease is still the number one killer worldwide. That alone should make us pause.In India, the picture is worrying. Studiessuggest that roughly 25–30% of urban adults have high cholesterol. In some cities, it’s even higher. Rural numbers used to be lower, but they’re climbing fast as diets and lifestyles change. What’s scarier is that heart attacks in India tend to happen earlier. People in their 30s and 40s are landing in ICUs, often with no idea they were at risk.And it’s not just older people or those who “look unhealthy.” Thin people get high cholesterol too. So do people who exercise but eat poorly. Genetics plays a role, but so does stress, sleep, smoking, and the everyday food we’ve normalised.Diabetes and glaucoma: Doctor shares tips to protect vision from the double threatNipah virus can remain dormant for up to 45 days: Doctors reveal why this silent period is dangerous for healthPart of the problem is awareness. Or the lack of it. High cholesterol doesn’t hurt, so it doesn’t feel urgent. In many families, blood tests are done only when someone falls sick. Preventive checkups aren’t routine. And when a report does show high cholesterol, it’s often brushed off. “It’s just a little high.” “I’ll fix it later.” Later doesn’t always come.There’s also confusion. Good cholesterol, bad cholesterol, triglycerides. The terms feel medical and boring. People tune out. Compare that to diabetes, where sugar levels can make you feel awful pretty quickly. Cholesterol doesn’t give that immediate feedback.Then there’s food culture. In India especially, rich food equals love, celebration, hospitality. Questioning it can feel rude or unnecessary. Add long work hours, stress, and very little time to move your body, and the risk quietly stacks up.Understanding cholesterol gives you control. It turns an invisible threat into something measurable and manageable. A simple blood test can tell you a lot. Small changes, made early, really do work. Waiting until there’s chest pain is the worst strategy.This isn’t about fear. It’s about paying attention before your body is forced to scream. High cholesterol may be silent, but the consequences are loud. And once you see that clearly, it’s hard to unsee.In order to help readers understand cholesterol and lipid disorder better, Dr. K. Seshi Kiran has answered a few questions around risks and preventive measures. Most people become aware of it only through routine blood tests. The one with a family history of heart disease, diabetes, high blood pressure, obesity, smoking habits, or a sedentary lifestyle should be careful. Sometimes, very high cholesterol can cause fatty deposits on the skin or around the eyes, but these signs are rare. Adults should ideally get a baseline cholesterol test in their early 20s. If cholesterol levels are normal and there are no major risk factors, testing every four to six years is usually sufficient. However, people above 40 years of age, or those with a family history of early heart disease, diabetes, obesity, smoking, or high blood pressure, may need more frequent testing, sometimes once a year. Lifestyle changes really do a lot of the heavy lifting when it comes to high cholesterol. What you eat, how often you move, whether you smoke, and even how much sleep you get all add up. Cut back on foods loaded with saturated fat, stay active most days, keep your weight in check, and your cholesterol numbers can improve more than you might expect, especially if they’re only mildly or moderately high.But here’s the honest part. For some people, lifestyle changes aren’t enough on their own. If cholesterol levels are very high, or if there’s a genetic issue like familial hypercholesterolemia, medication becomes necessary. And that’s okay. The best results usually come from doing both, not choosing one over the other. When cholesterol stays high for years, it slowly starts sticking to the inside of your blood vessels, forming fatty gunk that shouldn’t be there. Doctors call it atherosclerosis, and it means your arteries getting tighter and less flexible. As those passages narrow, less blood gets through to places that really need it, like your heart and brain. And sometimes, one of these plaques can crack open. That’s when things get scary. A heart attack. A stroke. Often without much warning.What makes it tricky is how quiet this whole process is. It can build up for years while you feel absolutely fine. That’s why catching high cholesterol early, and keeping it under control long term, matters so much. It’s about stopping the damage before it turns into something you can’t undo.A lot of people still think high cholesterol is only a “weight problem.” If you’re slim, you must be fine, right? Not really. Plenty of thin, active-looking people have unhealthy cholesterol levels and don’t realise it until a test says otherwise.There’s also this idea that cholesterol itself is bad. All of it. Which isn’t true. Your body actually needs some cholesterol to do basic things, like make hormones and keep cells working properly. The issue starts when the bad kind creeps up and stays there.And then there’s the pill mindset. Take a tablet and move on with life. But medication on its own isn’t a magic fix. Food choices, stress, sleep, and how much you move still matter. A lot.These myths sound harmless, but they do real damage. They make people delay getting tested or brush off numbers that shouldn’t be ignored. And over time, that quiet neglect can turn into serious heart trouble.Medical experts consulted This article includes expert inputs shared with TOI Health by: Dr. K.
