Hi I'm 13, I'm quite slim but my stomach is twice the size from the rest of me.
Does anyone know why this may be?
Or how I can get it slim?
(and no I'm not pregnant -.-)

Just wondering anyway :)

Give yourself some time to grow, you're only 13. Are there women in your family built that way?
Are you feeling discomfort? Has there been a change in your appetite ?

What sort of foods do you eat? What sort of exercise (sports, extracurricular activities) do you do?
