What will happen to me?

If you have diverticula that don't give you any problems, you won't need any treatment. If your diverticula become inflamed or infected (called diverticulitis), you'll probably be given antibiotics. If you don't get better, you may need treatment in a hospital.

If you have diverticula that don't give you any problems, you probably won't be offered any treatment. This is because you're unlikely to get ill.

Diverticula don't go away, but many doctors think that you can stop more diverticula from forming and stay well by eating more fiber.

Fiber is the part of fruits, vegetables and grains that your body doesn't digest. When you don't eat enough fiber, you can get

When you're constipated, you have difficulty passing stools (feces). Your bowel movements may be dry and hard. You may have fewer bowel movements than usual, and it may be a strain when you try to go.
 
 
 
 
 
constipated, with hard stools that are difficult to pass. Doctors think than when you strain to pass these hard stools, the pressure in your

Your colon is the first 2 metres (6 feet) of your large intestine. During digestion, food travels from your stomach to your small intestine and then to your large intestine. What's not digested then leaves your body as a bowel movement.

4 High-fiber foods make the stools softer and easier to pass through your colon. This reduces the pressure inside your colon.

Doctors think that fiber from fruit and vegetables may be better at preventing diverticula than fiber from cereals.

  • Apples and pears
  • Carrots, spinach, squash and broccoli
  • Potatoes
  • Baked beans and kidney beans.

It's best to increase the amount of fiber you eat gradually over a few weeks. Some people who eat more fiber feel worse before they start to feel better. This is because eating more fiber can make you feel bloated and uncomfortable at first.

Some doctors also think that exercise, such as jogging and running, also may stop you from getting diverticular disease. But there isn't any evidence in the research for this.

If you have inflamed or infected diverticula
If one or more of your diverticula become
 
 
 
 
 
inflammation
If your skin or some other part of your body becomes red, swollen, hot or sore, we say it is inflamed. It means that your body is trying to protect you from germs, from something in your body tissues that can hurt you (like a thorn or sliver), or from things that cause allergies (allergens). Inflammation is part of the way the body heals an infection or injury.
 
 
 
 
 
inflamed or
 
 
 
 
 
infection
You get an infection when viruses, bacteria, fungi or other tiny organisms get into your body. These bugs are so tiny that you can't see them without a microscope. For example, an infection in your airways causes the common cold. And an infection in your skin can cause rashes such as athlete's foot.
 
 
 
 
 
infected (when it's called diverticulitis) but you don't feel too sick, your doctor will probably look after you while you're at home. You'll probably be treated with
 
 
 
 
 
antibiotics
These medications are used to help your immune system fight infection. There are a number of different types of antibiotics that work in different ways to get rid of bacteria, parasites and other infectious agents. Antibiotics do not work against viruses.
 
 
 
 
 
antibiotics to fight the infection. And you’ll be put on a liquid diet to rest your colon.

  • Your pain is very bad
  • Your have a severe infection
  • You can't keep fluids down
  • You are over 85
  • You have another illness
  • You haven't gotten better after being treated at home.
In the hospital, you’ll probably be given fluids and antibiotics by injection into one of your
 
 
 
 
 
veins
Veins are blood vessels that carry blood back to your heart after your blood has delivered oxygen and food to the tissues.
 
 
 
 
 
veins. Most people treated in the hospital for diverticulitis get better with this kind of care. But 15 in 100 to 30 in 100 people need an operation to remove the affected part of their colon. This is sometimes because the antibiotics haven't worked or because of complication.

  • Abscess. This is a ball of infection and pus that may cause swelling and also damage your colon. If the abscess is small, it may clear up with antibiotic treatment. But if the abscess doesn't go away, you may need an operation to drain away the infected fluid. Your doctor will insert a needle through your skin and drain the fluid through a small tube called a catheter. Occasionally, you may need a bigger operation to clean the abscess and, if necessary, to remove part of your colon.
  • Fistula. This is an abnormal connection of tissue between the colon and nearby organs, such as the bladder, the small intestine or the skin. The most common type of fistula connects your bladder and your colon. Men are more likely to have this type of fistula than women. It can cause bad bladder infections. But your fistula can be cured by an operation to remove the fistula and the affected part of your colon.
  • Obstruction. If your diverticula have gotten infected, you can have scarring that can block your colon and stop your stools moving normally. You’ll usually need an operation to unblock your colon. If it’s only partly blocked, the operation can be planned in advance. But if your bowel is totally blocked, you’ll need an emergency operation.
  • Peritonitis. This is a very serious but rare illness that happens if the infection spreads outside your colon and into the space outside your gut. You'll need to have an emergency operation to clean the space and remove the damaged part of your colon. Without an operation, people who get peritonitis can die.
About one-third of people who have had an attack of diverticulitis, and don't get complications, get a second attack.

Because of this increased risk, some doctors recommend that people who've had two attacks of diverticulitis should have an operation to remove the diseased part of their colon.
