Call 911 or other emergency services immediately if the person has been bleeding from the anus and has signs of shock, which could indicate that a diverticular pouch is bleeding (diverticular bleeding).

Call your health professional immediately if you have pain in the abdomen that is in one spot (as opposed to general pain in the abdomen), especially if you also have:

• Fever or chills.
• Nausea and vomiting.
• Unusual changes in your bowel movements or abdominal swelling.
• Blood in your stool.
• Pain that is worse when you move.
• Burning pain when you urinate.
• Abnormal vaginal discharge.

Call your health professional immediately if you have:

• Severe pain in the abdomen that is getting worse.
• Pain in the abdomen that becomes worse when you move or cough.
• A stool that is mostly blood (more than a few streaks of blood on the stool). Blood in the stool may appear as reddish or maroon-colored liquid or clots or may produce a black, tarlike stool.
• Shoulder pain (possibly from air in the abdomen due to a hole or perforation in the intestine).

Call your health professional if you:

• Have cramping pain that does not get better when you have a bowel movement or pass gas.
• Pass gas or stool from your urethra while urinating. This indicates you have an opening (fistula) between the bowel and the urinary tract.

Watchful Waiting

It is not uncommon to have bloating, gas pressure, or mild abdominal pain. These can be caused by eating certain foods or by stress. Home treatment usually will take care of these symptoms. If home treatment does not help or if the symptoms become worse, see your health professional.
