After moving around alot (Ex- Chasing the cat for about 3 minutes) I have a pounding heartbeat and extremely lightheaded to the point where i feel like i'm going to passout/blackout. It lasts for about 30 seconds-1 min if i sit or lay down.. I sometimes get the same feeling after getting up, or going up/down stairs. Its been this way for several years.. but didnt think much of it really. I'm a 17 y/o female.. not active at all, spend most of my time sitting around.. about 113 lbs, 5'7''.. Any ideas why this is happening? Suggestions?.. please and thanks..
You have symptoms of anemia and/or low blood pressure. Or you could simply be out of shape. You can check your BP using a BP monitor. You will need to go to the doctor's office to test for anemia. You are somewhat thin for somebody who is 5-7 and 17 year old. 125-130 lbs would be a more ideal body weight. Try to eat more nutritious food and exercise more.
