Why does my 13 year old son struggle with basic physical activity

[Nicole1976]

I recently made a post about my sons weight gain and how rapid it was, but now I am starting to worry about his physical ability and exercise rate.
He doesn't do any exercises or sports now, which I wasn't too concerned about at first but now I have noticed that his walking is slower and when I gave him a lift to school this morning I saw that he was out of breath from just crossing the road and walking into the school,something which certainly doesn't seem normal.

P.s he is 4"11 and 8 stone 3pounds

Anyone with advice would be much appreciated

Maybe you should get him checked over at the doctors, to make sure that there is nothing wrong.......

I read your other thread.

It seems like your son needs a doctor quite quickly because this all isn't very normal.
