My stomach has suddenly become really bloated!! Help?!?

When you starve your self it damages, and slows down your metabolism, therefore something that may not have had any effect on your weight before, may now add on a few pounds. Just keep eating normally, and get your metabolism back into practice and it should speed up again. Also try and do a lot of exercise/be very active for like the next month to speed up your metabolism again, since exercise speeds up your metabolism. Don't worry, you didn't do any permanent damage as long as you weren't lying when you said you only went 1 week without being properly nourished. I had an eating disorder last year, and after I started eating again at first it gave me stomach aches, made me bloated, and gave me diarrhea, but after getting back into my old normal eating habits, and doing some exercise to speed up my metabolism again, I got back to normal. Just make sure you don't ever stop eating again! Going more than about 1 and a half weeks without proper nourishment, can lead to permanent damage to your metabolism because just like any muscle in your body, the less you use it, the weaker it gets (but don't eat too much either), and it can also lead to SERIOUS health issues, and even irreversible damage to your metabolism. I hope you feel better soon xoxoxo
