Statins, like all medications, have side effects or the possibility of adverse reactions. You don't mention your cholesterol
numbers, but in general unless you have risk factors for coronary artery
disease [CAD] (male age > 55, diabetes
, smoker, high blood pressure
, family history of CAD), you can use diet and exercise to keep your LDL
(bad cholesterol) below 130mg/dL. It isn't until you develop heart disease
that you need to target lower numbers-which usually requires medications.
I would urge you to research ways to change your diet to lower your cholesterol and avoid medications for as long as you can.
