Hello all. I am new here and I am wondering if you could help me with something.
I am 18. Recently I have noticed that I am getting extremely breathless after very little movement. Notably, I am finding it increasingly tiresome to climb stairs. I have not really exercised since I was about 5 years old, and since primary school have spent around 23h per day sitting, so my fitness has never been great. However, I have gained a significant amount of weight in the last 2 years and believe this may have something to do with the decline. Either that, or it is a different issue I should be looking into. Does anyone have any suggestions?
