I just recently had an ileostomy and everyone is telling me how good I look. I am now 6 weeks post op. I gained weight pretty quickly after the surgery because I was eating everything in sight due to the fact I was on prednisone for a few days and also because food just tasted so good again. When you dont eat much for 2 years because of the constant pain and running to the bathroom, being able to eat pretty much whatever whenever was amazing. I have more energy than I have had in a long time and I have been getting compliments on my looks since the surgery. I was very much underweight before the surgery and I looked sickly thin not healthy. I decided I needed to put some healthy weight back on, but I have decided to keep an eye on it and not get above 140 lbs as I am only 5'6". Just keep a weight in your mind as to what will be good for you and just remember the food is actually being absorbed into your body now so you will have more energy but also more weight gain. Good luck.
