High Cholesterol: The Silent Killer You Can't Feel

LAGOS, Nigeria — High cholesterol has no symptoms. That is why it is dangerous. Most people discover they have it only after a heart attack or stroke. Doctors call it a "silent killer" because it damages the body without warning. Dr. Happiness Akinde, a medical doctor, spoke with PT Health Watch about the hidden risks. She explained that anyone can have high cholesterol, even people who feel healthy. “You cannot see or feel high cholesterol,” Dr. Akinde said. “But it builds up in your arteries over time. This narrows the blood vessels and increases the risk of heart disease.” Who is most at risk? People with a family history of high cholesterol, those who eat a diet high in saturated fats, and individuals who do not exercise regularly. Age and being overweight also raise the risk. The only way to know your cholesterol level is through a blood test. Dr. Akinde stressed the importance of regular screening, especially for adults over 20. “Many people avoid testing because they feel fine,” she said. “But by the time symptoms appear, the damage may already be severe.” Everyday habits can silently increase cholesterol levels. Eating too much fried food, red meat, and processed snacks is a major cause. A lack of physical activity and smoking also contribute. Dr. Akinde advised simple changes: eat more fruits, vegetables, and whole grains. Exercise for at least 30 minutes a day. Avoid smoking and limit alcohol. High cholesterol is easy to miss. But with regular checks and healthy habits, it is also easy to control.
