I was told the normal cholesterol level is 100-187. i'm at 183. should i be worried since i'm so young and it's already at the high end of normal?

Cholesterol Level: Checking your cholesterol is important at your age so you can identify a potential issue that can contribute to your future risk of heart attacks and stroke. I would stress a low cholesterol diet as the initial therapy for any patient your age. Lifestyle changes such as exercise, weight control, and stopping smoking can have a profound effect on your future risk of strokes and heart attacks.

Lower cholesterol.: On the one hand, it would be great if your cholesterol was lower as a general health measure. On the other hand, we could better advise if we knew your entire cholesterol profile - this wouldn’t be as bad if you have a predominance of good cholesterol (HDL) relative to bad (LDL and triglycerides).
