How does a 14 year old female lower cholesterol 30 pts.? I m 14 and I ve been told that I have cholesterol levels of 30 pts. higher than normal by my doctor. I was wondering what cholesterol was exactly, how it affects me, and what it can lead to. Also, could anyone tell me how or what to do in order to lower it back to normal levels. Thank you all so much. Also I don t think I m even over weight because I am 5 1 and weigh 107 lbs.
