This Morning: Dr Chris reveals grapefruit can affect statins
Statins are a vital treatment for people with high cholesterol levels. High cholesterol can become very dangerous as it can lead to the clogging of arteries which can subsequently increase the risk of heart attacks, strokes and heart disease. But what are the advantages and disadvantages of taking statins?
What are statins?
Statins are a group of drugs which are used to lower blood cholesterol levels.
These drugs do this by blocking an enzyme in the liver which is necessary for making cholesterol.
Cholesterol plays a role in normal and healthy cell and body function.

However, extremely high levels of cholesterol can prove dangerous.
High levels of cholesterol can lead to atherosclerosis which causes cholesterol-containing plaques to build up in the arteries and block blood flow.
Essentially high cholesterol means you have too much of a fatty substance called cholesterol in the blood and is mainly caused by eating fatty food, a lack of exercise, being overweight, smoking and drinking alcohol.
Cholesterol can also be inherited and run in families generally.
What are the advantages of taking statins?
Statins can be offered to patients with high cholesterol as this medicine works to lower the level of low-density lipoprotein (LDL) cholesterol in the blood.
LDL cholesterol is often referred to as “bad cholesterol” and statins reduce the production of it inside the liver.
In addition to lowering your cholesterol, stains can also help to stabilise the blood vessel lining which benefits the whole body.
These drugs can make plaque less likely to rupture in the heart, lowering the risk of a heart attack.
Statins can also effectively relax the blood vessels which can lead to a decrease in blood pressure.
