eating after reversal

My husband was shot in December in the stomach, he underwent emergancy surgery where they tried to repair a torn intestine.  It ruptured and they had to do a colonostomy and an illiostomy.  He endured a bag for 6 months and he hated it, he went to docs to see if a reversal was an option and they said he was a great canidate.  He went in to have his reversal it was a success after one week he came home and tried to resume his normal eating habits, however when he ate things like sugar, fruit and certain dinner meals he would get ill.  I need to know what to do to get him the foods that won't make him ill.  I love him so much and he tries real hard not to complain.  I asked him if he could have his bag back would he want it and he said a loud and certain no way.  He hates being sick but he hates the bag more.  Please help me feed him correctly so that he won't get ill after eating.  He has thrown up several times and he has gas, belching and farting badly.  Please help

Good 4th of July, I had colon surgery 14 months ago and the surgeon wanted to do a colonostomy to wear for a while.  I refused the bag and had to heal from the resectioning the hard way, along with chemo.  In his case I would guess that his small intestine may have gone paralyzed from disuse and it will take time for it to get working correctly once again.  Miy small intestine had gone paaralyzed and it is still trying hard to get working right.  I too came home for a 7 week hospital stay and after several months of not being allowed to eat any solid food craved eating what I used to eat.  So, I pigged out and thought I was going to die.  He needs to eat very easy to digest foods, cooked cereals, mashed potatoes and gravy, put his meat through the blender and eat it with the gravy, rice, banannas or lightly cooked fruit, all vegetables cooked not raw, cottage cheese, greek yogurt,  avoid heavily spiced foods for a while, bread was okay with melted cheese on it, anything very soft, pudding is good too. It will take months to heal.  For gas, get GasX, it will help.  For vomiting or nausea, get Ondancetron (prescription), for really bad farting - get a closepin...  It too will last for months but does finally get better.  It has been over a year since my surgery and I am just now getting past the gas problems.  Thankfully I live alone with my cats and even they had to avoid me at times.   I can eat a lilttle green salad and small amounts of cooked meats.  I still have to be careful and not eat at night or I will vomit all night.  Just make sure he gets a lot of protein so he can heal properly.  I would also look on-line for dietary suggestions for diets following  intestinal surgery.  It will be very much like post surgical colon cancer diet suggestions.  And just be kind and both of you very patient with the healing.  I get impatient with this process, but it is necessary.  Bless you both...
