Advise Please?

I have always been a small person. The most I ever weighed was 112 lbs. Last summer I got sick and had to have two kidney stones removed, I vomited alot from the pain, it was unbearable. Also, I was under alot of stress and lost almost 20 lbs in a 2 month time frame. It took some time and I finally got my appetite back, however, I don't seem to be gaining that weight back. I think I gained about 5 lbs and its been 7 months. I am officially a size 0. Is this normal?? I weigh close to 100 lbs and i am 5'3. I do eat and I'm not sick anymore. Does it take time to gaint he weight back. I had to go out today an purchase new clothes because my pants hung off my waist.Advise Please?
well average weight for that height is only 115 so you're not really that small. i'm 5'3 and i wear a size 2 and my doctor always says i'm doing well. let nature take it's course and you'll be fine.
Listen, do you still have those stones. Can you send 'em to me? Sounds like a great diet.
Well, if your gonna Gain wait do not eat fat that is not healthy to be skinny like that. Eat Apples, fruit and stuff...I'm mean like get some food into you another words.
I know what you mean. My dad had 2 kidney stones also, and the doctor said he needed to gain weight. And if your shorter, you usually weigh less then taller people do. But try eating more, or ask a doctor what you should do.
u need to rest some more months at least 6 mths after ur operation.if u r still ok n ur kidneys r still perfect,i don't see u can't put on weight like b4.plz take times n patience.
