Ulcerative Colitis

What is ulcerative colitis?

Ulcerative colitis is part of a group of diseases called inflammatory bowel disease (IBD).

It is when the lining of your large intestine (the colon or large bowel) and your rectum become red and swollen or inflamed. In most cases the inflammation begins in your rectum and lower intestine and moves up to the whole colon.

Ulcerative colitis does not normally affect the small intestine. But it can affect the lower section of your small intestine (the ileum).

The inflammation causes diarrhea, making your colon empty itself often. As the cells on the lining of the colon die and come off, open sores or ulcers form. These ulcers may cause pus, mucus, and bleeding.

In most cases, ulcerative colitis starts when you are between the ages of 15 and 30 years old. Sometimes children and older people get it. It affects both men and women and seems to run in some families (is hereditary).

Ulcerative colitis is a long-term, chronic disease. There may be times when your symptoms go away and you are in remission for months or even years. But the symptoms will come back.

If only your rectum is affected, your risk of colon cancer is not higher than normal. Your risk is higher than normal if the disease affects part of your colon, and greatest if it affects your whole colon.

In rare cases, when severe problems happen, ulcerative colitis can lead to death.

What causes ulcerative colitis?

Experts don’t know what causes ulcerative colitis.

It may be that a virus or bacteria affect the body's infection-fighting system (immune system). The immune system may create abnormal redness and swelling (inflammation) in the intestinal wall that does not go away.

Many people with ulcerative colitis have abnormal immune systems. But experts don’t know if immune problems cause the disease. They also don’t know if ulcerative colitis may cause immune problems.

Having stress or being sensitive to some foods does not seem to cause ulcerative colitis.

Right now there is no cure except for surgery to remove the colon.

Who is at risk for ulcerative colitis?

Some things may make you at higher risk for ulcerative colitis. These include your:

  • Age. The disease most often starts when you are between the ages of 15 and 30 years old.
  • Family history. Having a family member or close blood relative with ulcerative colitis raises your risk of getting the disease.
  • Race and ethnicity. It happens more often in whites and people of Jewish background

What are the symptoms of ulcerative colitis?

Each person’s symptoms may vary. The most common symptoms include:

  • Belly pain
  • Bloody diarrhea
  • Extreme tiredness (fatigue)
  • Weight loss
  • Loss of appetite
  • Rectal bleeding
  • Loss of body fluids and nutrients
  • Loss of blood (anemia) caused by severe bleeding

In some cases, symptoms may also include:

  • Skin sores
  • Joint pain
  • Redness and swelling (inflammation) of the eyes
  • Liver disorders
  • Weak and brittle bones (osteoporosis)
  • Rashes
  • Kidney stones

The symptoms of ulcerative colitis may look like other health problems. Always see your healthcare provider to be sure.

How is ulcerative colitis diagnosed?

Your healthcare provider will give you a physical exam and do some blood tests. The blood tests will check your red blood cells and white blood cells. If your red blood cell count is low, this is a sign of anemia. If your white blood cell count is high, this is a sign of redness and swelling (inflammation).

Other tests for ulcerative colitis include:

  • Stool culture. Checks for any abnormal bacteria in your digestive tract that may cause diarrhea and other problems. To do this, a small stool sample is taken and sent to a lab. In 2 or 3 days, the test will show if abnormal bacteria, bleeding, or infection are ­present.
  • Upper endoscopy, also called EGD (esophagogastroduodenoscopy). This test looks at the inside or lining of your food pipe (esophagus), stomach, and the top part of your small intestine (duodenum). This test uses a thin, lighted tube, called an endoscope. The tube has a camera at one end. The tube is put into your mouth and throat. Then it goes into your esophagus, stomach, and duodenum. Your healthcare provider can see the inside of these organs. He or she can also take a small tissue sample (biopsy) if needed.
  • Colonoscopy. This test looks at the full length of your large intestine. It can help check for any abnormal growths, tissue that is red or swollen, sores (ulcers), or bleeding. A long, flexible, lighted tube called a colonoscope is put into your rectum up into the colon. This tube lets your healthcare provider see your colon lining and take out a tissue sample (biopsy) to test it. He or she may also be able to treat some problems that may be found.
  • Biopsy. Your healthcare provider will take out a tissue sample or cells from the lining of your colon. This will be checked under a microscope.
  • Lower GI (gastrointestinal) series, also called barium enema. This is an X-ray exam of your rectum, the large intestine, and the lower part of your small intestine (the ileum). You will be given a metallic fluid called barium. Barium coats the organs so they can be seen on an X-ray. The barium is put into a tube and inserted into your rectum as an enema. An X-ray of your belly will show if you have any narrowed areas (strictures), blockages, or other problems.
  • Blood tests. No blood test can diagnose or rule out ulcerative colitis, but many tests can be helpful to monitor the disease and sometimes help better define the disease.

How is ulcerative colitis treated?

Your healthcare provider will create a care plan for you based on:

  • Your age, overall health, and past health
  • How serious your case is
  • How well you handle certain medicines, treatments, or therapies
  • If your condition is expected to get worse
  • Your intended family plans, such as getting pregnant
  • What you would like to do

There is no special diet for ulcerative colitis. But you may be able to manage mild symptoms by not eating foods that seem to upset your intestines.

Medical treatment may include:

  • Medicines. Medicines that reduce redness and swelling (inflammation) in your colon may help to ease your belly cramps. More serious cases may need steroids, medicines that fight bacteria (antibiotics), or medicines that affect your infection-fighting system (immune system). Steroids are not a good choice for long-term management. Therefore, your healthcare provider will discuss medicines for long-term control. This may include pills, injections, or a combination. In addition, placing a medicine into the rectum (foam, enema, or suppository) can be very helpful in controlling your symptoms.
  • Hospitalization. This may be needed if you have severe symptoms. The goal will be to give you the nutrients you need, stop diarrhea, and replace lost blood, fluids, and electrolytes (minerals). You may need a special diet, IV (intravenous) feedings, medicines, or sometimes surgery.
  • Surgery. Most people don’t need surgery. But some people do need surgery to remove their colon. That might happen if you have heavy bleeding, are very weak after being ill for a long time, have a hole (perforation) in your colon, or are at risk for cancer. You may also need surgery if medical treatment fails or if the side effects of steroids and other medicines become harmful.

There are several types of surgery, including the following:

  • Proctocolectomy with ileostomy. This is the most common surgery. It is done when other medical treatment does not help. Your entire colon and your rectum are removed. A small opening (stoma) is made in your belly wall. The bottom part of your small intestine (the ileum) is attached to the new opening. Your stool will come out of this opening. It will collect in a drainage bag that will be attached to you.
  • Ileoanal anastomosis. Your whole colon and the diseased lining of your rectum are removed. The outer muscles of your rectum stay in place. The bottom part of your small intestine (the ileum) is attached to the opening of your anus. A pouch is made out of the ileum. The pouch holds stool. This lets you pass stool through your anus in the normal way. You will still have fairly normal bowel movements. But your bowel movements may happen more often. They may also be more watery than normal.

If your colon remains inside, you will need a colonoscopy at various intervals because of your increased risk of colon cancer.

What are the complications of ulcerative colitis?

Ulcerative colitis is a long-term, chronic condition. It can lead to problems over time, including:

  • Loss of appetite, leading to weight loss
  • Lack of energy (fatigue)
  • Severe bleeding (hemorrhage)
  • Hole or tear (perforation) in the colon
  • Infection of the colon
  • Severe fluid loss (dehydration)
  • Joint pain
  • Eye problems
  • Kidney stones
  • Weak, brittle bones (osteoporosis)
  • Colon cancer, if ulcerative colitis affects much of or the whole colon over a long period of time

In rare cases, when severe problems occur, ulcerative colitis can lead to death.

Can ulcerative colitis be prevented?

Experts don’t know what causes ulcerative colitis. They also don’t know how to stop the disease from happening.

When should I call my healthcare provider?

Call your healthcare provider right away if:

  • Your symptoms come back after they have gone away
  • Your symptoms worsen
  • You have new symptoms

Management of Ulcerative Colitis: Lifestyle

Three people talking in support group.You can lead a full life even if you have ulcerative colitis. Focus on keeping your symptoms under control. And don’t let this disease isolate you. By planning ahead and working with support groups, you can find ways to cope. And you may even help others who have ulcerative colitis.

Ulcerative colitis is a type of inflammatory bowel disease (IBD).

Have a plan

Make this your goal: “Ulcerative colitis won’t keep me from the activities I enjoy.” You may need to do some planning to reach that goal. But by staying positive, you can help make sure you’re in control—not ulcerative colitis. Here are some other tips:

  • Know where to find clean bathrooms.

  • Eat more small meals instead of 3 big meals, especially when on the road or when you don’t have easy access to bathrooms.

  • If you’ve had a recent flare-up, eat foods that you know will limit your symptoms. Keep those foods on hand, both at home and at work.

  • Get some exercise every day.

  • Take a stress reduction class.

  • If going on a long trip, discuss your plans with your healthcare provider. He or she can teach you what to do if you have a flare-up while on the road.

Find a support group

Ulcerative colitis support groups can help you with many concerns you may have. Other people have felt much of what you may be feeling. Just knowing that you’re not alone can be a great comfort. Or someone in a support group may offer a travel tip or a coping skill that’s perfect for you. And don’t forget how satisfying it can feel to help another ulcerative colitis patient who’s in need. Contact the Crohn’s and Colitis Foundation toll-free at 800-932-2423.

Managing nutrition

You may be able to eat most foods until you have a flare-up. But like anyone else, you need to make healthy eating choices. Some of the healthiest foods can make symptoms worse, though. Keeping track of your “problem foods” may be helpful. Ask your healthcare provider any questions you have about healthy eating.

Avoid your problem foods

There’s no rule for which foods can be a problem. How you feel after eating them is the best guide. You may need to avoid high-fiber foods and foods that are hard to digest. These can include fresh fruits and vegetables. High-fat foods, such as whole-milk dairy products and red meat, can also worsen symptoms in a flare-up. Write down what you eat and how it affects you. If one kind of food often gives you trouble, stay away from it. Also note the foods that work well for you. Your healthcare provider may have you see a nutritionist to come up with the best food choices for you. A nutritionist can help ensure that you eat foods that are “safe” while getting proper nourishment.

Foods that are often “safe”

No two people respond the same to all foods. But these choices are often “safe” to eat during a flare-up:

  • Applesauce

  • Melba toast

  • Flavored gelatin

  • Vanilla pudding

  • Custard

  • White rice

  • Plain pasta

  • Canned peaches or pears

  • Baked potatoes 

  • Tuna packed in water

  • Mashed potatoes

  • Skinless chicken

  • Instant oatmeal
