damage comes, from among other things,
high blood pressure and cholesterol build up,,,,, lowing both decreases your risk,,,,,,getting to a healthy weight and diet lowers both,,, at your age, i wouldnt think the damage had alot of build up time,,,,,,,,make sure and check the sodium and fat content of what you eat,,,, as its not just in how much you weigh, but also your diet and family history,,,,, have a check up at the doctor to see what condition you are in now,,,,, and a basic blood work up,,,, you could have a tendency inherited for
high cholesterol,,, its best to start yearly or every other year check ups at this age anyway,,,,,,
for example, i have always been thin, yet
heart disease runs in my family, we have a tendency to have high cholesterol,,,,, no one knew this years ago, if i hadnt happened to have blood work to show it,,,,, i would of went years with it building up, even though i ate a mostly low fat/lowcholesterol diet,,,,,,,
