I am extremely tiredness when I'm running or climbing stairs, also my heart it's beating to fast after this little effort and I have shortness to breath. What's the problem?
Hi, difficulty in breathing on exertion, rapid heart rate, tiredness on slight exertion is suggestive of anemia in absence of other systemic illness. You can check blood hemoglobin to rule out possibilities of anemia. Even Health Ever offers a list of home remedies and diet to boost up your body stamina.
