There are two main types of cholesterol: low-density lipoprotein (LDL) or “bad” cholesterol, and high-density lipoprotein (HDL) or “good” cholesterol. High levels of LDL cholesterol can lead to plaque buildup in the arteries, while HDL cholesterol helps remove LDL cholesterol from the arteries.

Risk factors for high cholesterol include an unhealthy diet high in saturated and trans fats, lack of physical activity, obesity, smoking, excessive alcohol consumption, and genetic factors.

Yes, high cholesterol can often be prevented or controlled through lifestyle changes, such as maintaining a healthy diet low in saturated and trans fats, regular exercise, weight management, and avoiding smoking.

In some cases, lifestyle changes alone may not be sufficient to manage high cholesterol levels, and medication (such as statins) may be prescribed by a GP to help lower LDL cholesterol levels and reduce the risk of cardiovascular disease.
