Your body needs cholesterol to function properly; too much, however, can cause a variety of health problems. For example, high cholesterol can cause a condition called atherosclerosis (hardening of the arteries), the effects of which can include coronary heart disease, angina, and stroke. Unfortunately, there are no early symptoms of high cholesterol, and many people are unaware that they have the condition.
The exact causes of high cholesterol are unknown, but risk factors include diet, weight, family history, high blood pressure, and nicotine use. Treatment often involves lifestyle changes, like exercising more and eating a heart-healthy diet. If lifestyle changes alone do not lower cholesterol enough, medication may be necessary.
