Crohn disease is a disease in which parts of the digestive tract become inflamed. It is a form of inflammatory bowel disease (IBD).
Crohn disease, also called regional enteritis, is a chronic inflammation of the intestines which is usually confined to the terminal portion of the small intestine, the ileum. Ulcerative colitis is a similar inflammation of the colon, or large intestine. These and other IBDs (inflammatory bowel disease) have been linked with an increased risk of colorectal cancer.
Living with Crohn's disease can be a constant gamble, hoping this won't be the day when your disease flares up. Crohn's disease is a type of inflammatory bowel disease. It's caused by a malfunction in the body's immune system. Normally, the immune system protects against bacteria and other foreign invaders. But in people with Crohn's disease, it mistakenly attacks the intestines, causing them to swell up and thicken. As a result, people with Crohn's disease have bouts of severe abdominal pain, diarrhea, and pain with bowel movements. They can lose their appetite, feel tired, and lose weight without meaning to. Some have severe mouth sores. If you've been experiencing any of these symptoms, your doctor can test for Crohn's with a colonoscopy using a scope to look at your colon from the inside. A wireless video capsule may be swallowed to look at the small intestine. Blood tests or other imaging studies may be needed as well. If you're concerned about Crohn's, stop smoking. Smoking can increase your chance of getting Crohn's disease and once you have it smoking can make the condition worse. Medicines can help with the symptoms of Crohn's disease. There are medicines to control diarrhea, and pain relievers to help with abdominal cramps. There are also medicines that quiet the overactive immune response that causes Crohn's. Changing your diet may make a big difference in preventing or reducing symptoms. But as diet that works well for you may be different than the one that works for others. Eating several small meals a day instead of three big ones prevents your intestines from having to process large amounts of food at once. Your doctor may also recommend that you drink lots of water, and avoid high-fiber and high-fatty foods, as well as any foods that you know make you gassy, perhaps beans or broccoli. You may also need to take iron, B12, and other vitamin and mineral supplements if your Crohn's is preventing you from getting enough nutrients through your diet. If medicines and diet changes aren't enough to reduce your symptoms, and you develop bleeding or an infection in your intestines, you may need a procedure called a bowel resection to remove the diseased part of your intestines. This procedure won't cure Crohn's, but it can help control the complications of the disease. If you're experiencing Crohn's symptoms, like stomach pain, severe diarrhea, or unplanned weight loss, call your doctor. Although there's no cure for Crohn's, treatments can relieve some of the uncomfortable symptoms, prevent complications, helping improve your quality of life.
You were in the hospital because you have Crohn disease. This is an inflammation of the surface and deep layers of the small intestine, large intestine, or both. Less often, other parts of your gastrointestinal tract can be affected.
You may have had exams, lab tests, stool tests, and imaging tests such as CT or MRI. The inside of your colon (large intestine) and ileum (last part of the small bowel) may have been examined using a flexible tube (colonoscopy). A sample of your tissue (biopsy) may have been taken.
You may have been asked not to eat or drink anything and have been fed only through an intravenous line. You may have received special nutrients through a feeding tube.
You may have also started taking new medicines to treat your Crohn disease. Treatment usually involves long-term medicines that blocks the immune system from causing inflammation. This may be by pill , infusion, or injection. These medicines will be continued at home.
Surgeries you may have had include repair of a fistula, small bowel resection, dilation of a narrowing (called a stricture) or ileostomy.
After a flare-up of your Crohn disease, you may be more tired and have less energy than before. This should get better. Ask your health care provider about any side effects from your new medicines. You should see your provider regularly. You may also need follow-up blood and stool tests, especially if you are on new medicines.
If you went home with a feeding tube, you will need to learn how to use and clean the tube and your skin where the tube enters your body.
Immunosuppressive medicines for IBD can make you at higher risk of getting other infections. Make sure to speak with your provider about getting the appropriate vaccinations to decrease your risk. Live vaccinations are not given while on those medicines, so follow your provider's guidance.
If you are planning to get pregnant in the near future, discuss with your provider. It is best to have your Crohn disease under control (be in remission) before pregnancy.
When you first go home, you may be asked to drink only liquids or eat different foods from what you normally eat. Ask your provider when you can start your regular diet.
You should eat a well-balanced, healthy diet. It is important that you get enough calories, protein, and important nutrients from a variety of food groups.
Certain foods and drinks can make your symptoms worse. These foods may cause problems for you all the time or only during a flare-up. Try to avoid foods that make your symptoms worse.
Eat smaller meals, and eat more often. Drink plenty of liquids.
Ask your provider about extra vitamins and minerals you may need:
Talk with a dietitian, especially if you lose weight or your diet becomes very limited.
You may feel worried about having a bowel accident, embarrassed, or even feel sad or depressed. Other stressful events in your life, such as moving, job loss, or the loss of a loved one, can cause problems with your digestion.
These tips help you to manage your Crohn disease:
Your provider may give you some medicines to help relieve your symptoms. Based on how bad your Crohn disease is and how you respond to treatment, your provider may recommend one or more of these medicines:
There are many types of medicines that can help prevent or treat attacks of your Crohn disease. Some of these are often started in the hospital.
