Hi,
I'm 13,but my cousin has let me borrow her account so I can post this. I seem to have a problem controlling my weight, but I don't know what is causing it: I appear to gain weight rapidly whenever I eat anything, for example at dinner tonight I ate 3 small bread rolls, 1 sausage, half a burger and salad, followed by 1 merrange nest, lots of strawberries and a small scoop of ice cream and, having weighed myslef before and after the meal, I have gained three pounds. My Mum has an under active thyroid gland, but I'm not sure if I have this condition. What could be causing such rapid weight gain?
