Statins work by inhibiting a particular enzyme, HMG-CoA reductase, which controls the rate of cholesterol production in the body. This causes the liver to make less cholesterol. Statin benefits also include:
Increasing the liver's ability to collect and get rid of LDL cholesterol ("bad" cholesterol)
In general, cholesterol treatment begins with lifestyle changes (weight loss, exercise, and a low-cholesterol diet). However, if lifestyle changes alone do not lower cholesterol to a desirable level, medication such as statins may be necessary.
