I had severe diverticulitis and ended up with the surgery to remove 35cm of my bowel. After the surgery which went well by the way I developed C Diff which was very hard to fix but with pretty much the strongest antibiotics I am got rid of it.
It took a long time for my bowels to adjust as time went on I got better. Yes there is a but, my bowels and stomach have never been the same as some foods will just set me off so to speak so less fatty foods for me these days.
If I didn’t have the surgery I wouldn’t be here writing this so yes the surgery to fix the problem is best as you can jeep in living. Just as another note, my surgeon said I must have a colonoscopy after 12 months to check for adhesions and I’m nearly at the 12 months stage so we shall see how it’s all going inside soon.
I wish you the very best and definitely listen to your surgeon.
