My husband had a total colectomy 27 yrs ago. Diarrhea will be part of life because your colon is where the water gets reabsorbed and our husbands don’t have them anymore.
But the pain and vomiting happen when my husband gets a blockage in the area of his scar tissue where they reconnected his colon and rectum.
Not sure if this is what’s happening with your husband? Is it pain all the time? Or just sometimes and then it gets worse and he vomits?
If it’s all the time, then it must be something going on in the small intestine.
But I know for sure after colectomy, they can’t eat a high fiber diet (no raw or firm fruits and veggies, corn, grapes, beans, etc.)
Let me know and I am happy to share all we have learned over the past years! We had to learn it all the hard way!
