High cholesterol is caused by many factors. Genetics, lifestyle choices, and health conditions can all contribute to high cholesterol.
-
Unhealthy diet: A diet high in saturated and trans fats can lead to high cholesterol. Saturated fats are found in animal products such as red meat, butter, and cheese. Trans fats are found in processed foods such as crackers, cookies, and margarine. Dietary cholesterol, like that found in eggs, is generally no longer considered harmful.
-
Lack of exercise: Physical inactivity can lead to high bad cholesterol (LDL) as well as low good cholesterol (HDL). Exercise is, in fact, the best way to increase your HDL. A sedentary lifestyle combined with an unhealthy diet, on the other hand, can be a recipe for disaster.
-
Smoking: Smoking damages and hardens the lining of your arteries, leading to a much higher chance of cholesterol-induced plaque buildup (atherosclerosis).
-
Age and gender: Your cholesterol levels rise as you age. Men are also more likely than women to have high cholesterol.
-
Being overweight: Excess weight can raise your cholesterol levels.
-
Family history: Genetics can play a large role in determining how much cholesterol your body makes. Sometimes, family lineages can even pass on Familial Hypercholesterolemia (FH), a condition in which the body produces a huge excess of it. FH isn’t curable, but it can be well managed with your doctor to get levels back into a normal range.
