What are the Symptoms of High Cholesterol?
High cholesterol often develops without noticeable signs. Many people don’t realize they have it until serious problems happen. In some cases, a few physical signs may appear, though they aren’t always obvious. Here’s a list of possible symptoms:
-
Chest pain during activity or stress, caused by narrowed arteries
-
Xanthomas, which are yellowish fatty deposits under the skin, usually on elbows, knees, or around the eyes
-
Fatigue or breathlessness during routine activities
-
Pain in the legs due to blocked arteries in the lower body
-
Sudden dizziness or numbness if a blood vessel is partially blocked
-
Heart attack or stroke, sometimes the first sign of dangerously high cholesterol
Most of the time, a blood test is the only way to know if cholesterol levels are too high.
Common Causes of High Cholesterol
Several factors contribute to high cholesterol, some related to lifestyle and others to genetics. Here’s a breakdown:
-
Unhealthy diet rich in saturated and trans fats, found in fried foods, processed snacks, and fatty meats
-
Lack of physical activity, leading to weight gain and poor cholesterol balance
-
Smoking, which lowers good cholesterol (HDL) and raises bad cholesterol (LDL)
-
Alcohol overuse, affecting the liver’s ability to manage cholesterol levels
-
Obesity, which often increases harmful cholesterol while reducing beneficial types
-
Family history, where genetic factors cause high cholesterol even in people who eat well and stay active
-
Medical conditions such as diabetes, kidney disease, and thyroid problems can also affect cholesterol levels
-
Age, as cholesterol tends to rise after 40
-
Stress, which may indirectly contribute through poor eating habits and inactivity
