Intestinal blockage can occur in people with Crohn’s disease. Blockage occurs because the intestinal wall thickens or swells from inflammation and scar tissue. Ulcers can also cause tunnels to form through the inflamed areas of the intestine or even the healthy parts. These tunnels are called fistulas. Sometimes pockets of infection, called abscesses, can form in and around the fistulas. Fistulas can be treated with medicine, but sometimes surgery is needed.
People with Crohn’s disease often don’t get the nutrients they need. If you have Crohn’s disease, you may not get enough protein, vitamins, or calories in your diet. If you aren’t getting nutrients, it may be because you
-have an upset stomach that keeps you from eating enough
-may be losing protein in the intestine
-may not be able to absorb nutrients from your food
Other problems that some people with Crohn’s disease suffer from are arthritis, skin problems, swelling in the eyes or mouth, kidney stones, and gallstones.
