Atherosclerosis???

hello. im a 14 year old boy. i weight 120lbs., and am about 5'6''. this is thin. i have no family history of atherosclerosis. however, sometimes ill get dizzi when i stand up after sitting, or at church when i stand. what is the likelihood that i have atherosclerosis? it's not in my family, and i don't think any heart prob.'s really are.sometimes ill get pain under my heart out of nowhere that hurts when i breathe deep. also, at bball, after running something hard, i sometimes have a hard time getting air. what couldi have?could it be atherosclerosis? thanks.

what you described is called orthostatic hypotension, decrease of blood pressure when moving from sitting to standing. it is noral at your age. you just have to adjust to it by doing this movement slowly. as for your chest and heart discomfort, if it happens after sternous exercices then it is ok. if it occurs on rest or follwoing mild exercise then you'd better see your doctor.
good luck

Dear, I don't think you need to worry about atherosclerosis. Just eat healthy and exercise. As far as the chest discomfort and "hard time getting air" -- sounds like you might have asthma. It can be treated very well and you can probably function normally. Just see your doctor.

Your symptoms don't even come close to those of atherosclerosis.
If you want an answer, see your doctor. Be sure to explain to him/her you symptoms just as you did when you wrote here. That will give the doctor the information he/she needs in order to determine what to do next.
