Did you mean either one of these
What is the difference between a colectomy and a colostomy? The main difference in a colectomy and a colostomy is that in a colectomy the large intestine is completely and irreversibly removed, and in a colostomy, the large intestine may have some part removed, but otherwise remains in place.
because a colonoscopy is no big deal. Just a test to check for cancer of the colon.
Well he has to wear a bag, that’s all I know. He had ulcerative colitis, and was bleeding, etc. I’ve had IBS most of my life. They used to give me all kinds of medications for it, and was tested for what he had several times, but for just IBS I learned you can find a diet that works for you to control it somewhat, so I was able to quit taking the medications. For me, eating few processed carbs and more fresh veggies and fruits worked. I credit that with the fact that I was the only one that I know of in my family that didn’t get diabetes. The silver lining. :-)
