Re: Can diverticulitis make you feel really sick?
In short, Yes.
I have had Pain, Diarrhea, bloating, nausea, shortness of breath and a general feeling of fatigue...
Come to find out, my last diverticulitis attack perforated my colon and the fatigue is from the toxicity of what is leaking into my abdominal cavity.
So yes, it can generally make you feel like crap. (no pun intended)
Definitely follow up with your Doctor.
Also, I would suggest going on chicken broth and other clear liquids for a couple of days with absolutely no gluten or dairy. Your observations as you gradually add things back to your diet can help your doctor figure out if there are other things going on.
