Your intestine is the long tube in your digestive system that digests food and absorbs nutrients. You have a large intestine and a small intestine. Your large intestine (colon) connects your small intestine with your rectum (the pouch at the end of your large intestine where stool is stored until you pass it). Small sacs or pouches (diverticula) can develop in your large intestine. They're probably caused by high pressure in the intestine. Having several of these pouches is called diverticulosis.
What is diverticulitis?
What causes diverticulitis?
Diverticulitis happens in people who have diverticulosis, a condition in which sacs or pouches form in your large intestine.
Sometimes, stool and bacteria get into one of the sacs (diverticula), causing inflammation and infection.
If you have diverticulosis, you have a higher risk of getting diverticulitis if you:
What are the symptoms of diverticulitis?
Diverticulitis causes:
Diverticulitis can cause problems such as:
-
Abscess (a collection of pus)
-
Infections in nearby organs or in the belly space between organs (peritonitis)
-
Serious infection in your blood causing other organs not to work right (sepsis)
-
Intestinal blockage from scarring in the intestine
-
Fistula (an abnormal connection between two organs that shouldn’t connect, such as the intestine and the bladder)
How can doctors tell if I have diverticulitis?
How do doctors treat diverticulitis?
You can treat mild diverticulitis at home with:
If you have more serious symptoms, you may need to stay in the hospital for treatment. Your treatment may involve:
You may need emergency surgery if:
Your doctor removes the ruptured (burst) part of your intestine. Then your doctor will either reconnect your intestine or give you a temporary colostomy. A colostomy is a surgical opening in your belly connected to one end of your intestine. Stool exits into the colostomy bag while your intestine heals.
A fistula that forms can also be treated with surgery.
Several weeks after you're better, doctors usually do a colonoscopy (a test in which a doctor inserts a thin, lighted tube with a small camera through your rectum to look at your large intestine) to be sure that your intestine has healed.
Doctors will also tell you to:
It's important to call your doctor if symptoms of diverticulitis happen again.
