Hi all. Firstly, i'm a teenage guy, 17 this year and i am underweight with a BMI of 18.

But, i've been having problems with my stomach for 5 years..

Some morning, i may wake up with a completely flat stomach. i would then have a glass of juice or milk and POP, my stomach is no longer flat! which annoys me greatly...And that everything i ingest something, my stomach increase in size again.. which is why i try my best to avoid buffets..

this is not solely a physical problem... well when i have a function or am going out with my pals and have decided to wear something rather fitting, i would have to not eat anything for the entire day so that i would look great in these attire. it is very frustrating actually, to limit myself and my food intake because of my stomach...this is parallel when i need to go for a swim or to the beach with my friends...

There are many days i would just starve myself because i cant afford to look bad...

i need help.

What is also worrying me is that my arms and thighs are slim or not tonned.

any suggestions? also, i dont eat breakfast because i dont really have time for it.

PS: the worst thing is that i can eat a lot...a lot... a lot. but i cannot allow myself to eat till my fill or i'll look really bad the next day.

God bless all who tries to help
i'm sick of this.

Denny.
