One of the most common causes of high cholesterol levels in the blood is eating too much saturated fat.
Lack of regular exercise, being overweight, drinking a lot of alcohol and smoking can also raise cholesterol levels. These are all factors you can change to help lower your cholesterol levels and reduce your risk of developing coronary heart disease.
There are some factors that increase your risk of having raised cholesterol levels that can’t be changed. These include having a family history of raised cholesterol or early cardiovascular disease, being over 40 years old and having a diagnosis of most conditions that affect cholesterol levels. For example, around 1 in every 500 people have high cholesterol levels caused by a genetic condition called Familial Hypercholesterolaemia.
If any of the factors that can’t be changed apply to you, it’s even more important you focus on making changes to the factors above that you can control.
