Dear Doctor,    I am 39 years old, 55kilos, and 5ft tall. I have no medical history. But recently, I am feeling weak, can`t have a good run for 5 meters, have to rest for a while after going upstairs in second floor coz i lose a bit of my breath and my blood pressure is 100/57.     What seems to be wrong with my body? Thank you in advance.
Hey, you have dyspnea on exertion & easy navigability. You first need to get your He(hemoglobin) checked. Secondly you should get a stress echo done to rule out Coronary Disease. Don't do a TMT rather get a stress echo done which include baseline echo followed by post exercise echo. Chat Doctor.
