<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, I have been having abdominal pain and bloating for the past few weeks. I also experience constipation and diarrhea alternatively. My friend told me it could be Diverticulosis.  <response>: Based on your symptoms, it is possible that you have Diverticulosis. In order to confirm this, we need to perform a sigmoidoscopy or colonoscopy. This will help us examine the inside of your colon for the presence of small pouches or diverticula. We may also need to conduct a complete blood count, x-ray computed tomography scan, colonoscopy with biopsy, urinalysis and measure your glucose levels. If your condition is severe, we may also consider intravenous fluid replacement to manage your symptoms.
