Diet alone doesn't cause ulcerative colitis or other inflammatory bowel diseases (IBD), and avoiding certain foods won't cure these conditions.
"But following a proper diet can help ease symptoms and promote healing," says David T. Rubin, MD, co-director of the Inflammatory Bowel Disease Center at the University of Chicago. In other words, choosing the right foods can make it much easier to live with ulcerative colitis and other chronic conditions.
Microscopic colitis is a type of inflammation of the colon, or large intestine, that can cause watery diarrhea and cramping. While it can be painful and unpleasant, in most cases it's much less severe than other types of inflammatory bowel disease.
It's called microscopic because the inflammation is too small to see with the naked eye. The only way your doctor can diagnose it is to take a sample of tissue and check it under a microscope.
There are two types of microscopic colitis:
But doctors say there's very little rhyme or reason to what causes problems for one person and not another. Even the same sufferer may experience a flare-up with a particular food at one meal and not at another.
How can you know which foods affect your symptoms? The best strategy, experts say, is to keep a food-and-symptom diary. "Every patient is different," says Rubin. "Individual experience should guide your food selection. That's why keeping a food diary for a few weeks can be very useful."
Dear Diary: Diet and Ulcerative Colitis
The idea is simple. By recording exactly what you eat over a period of time and how you feel afterward, you can nab particular foods that cause your symptoms to flare up. You'll also be able to identify foods that soothe your digestive tract.
Make recording your meals convenient for you. Some dietitians recommend using a notebook small enough to carry with you. That way you can jot down what you eat at meals and in between throughout the day. Others say it's fine to keep a notebook by the side of the bed and record everything you ate that day before going to sleep.
"Most people are pretty good at remembering what they ate over a 24-hour period," says dietitian Tracie Dalessandro, RD, author of What to Eat with IBD. "I find that filling in the diary just once a day is easier and more convenient for many people than pulling it out after every meal."
