Whenever Serena Ehrlich goes someplace new, she scouts out the location of the bathroom. That's because Ehrlich, 38, a Los Angeles-based salesperson for a commercial wire service, has ulcerative colitis. She developed the disease 12 years ago and has been in remission for the past three. Still, the old habit lingers. "Everyone who has ulcerative colitis will tell you that when you walk into a bookstore, a shop, or a restaurant, that's the one thing you want to know first. It's our rule of thumb."
This does not surprise David T. Rubin, MD, associate professor of medicine and co-director of the Inflammatory Bowel Disease Center at the University of Chicago Medical Center. "Ulcerative colitis makes people miserable psychologically," he says, noting that people with the condition often need to go to the bathroom suddenly, without any warning.
"Your entire world begins to revolve around it. And you can't share the information because there's a stigma with talking about the bowels. So [some] people stay home and worry that they'll live the rest of their lives this way," he says.
Ulcerative colitis affects the large intestine (also known as the colon) and the rectum. It causes inflammation of the colon's inner lining and the rectal wall, which become red, swollen, and ulcerated, resulting in abdominal pain or cramping, rectal bleeding, whitish mucus, and diarrhea. Less common are fatigue, appetite loss, and anemia. Some people also have joint pain, redness, swelling, and liver problems.
An estimated 250,000 to 500,000 Americans have ulcerative colitis, although Rubin believes that number is higher. "We think the number is 700,000, and that's probably an underestimate," he says, noting the statistics are taken from small studies that may not represent the entire population. Although most people are diagnosed before age 30, children as young as 10 can develop the condition.
Ulcerative colitis is often confused with two other digestive disorders: irritable bowel syndrome (IBS) and Crohn's disease. The common irritable bowel syndrome affects both the small and large intestines, causing abdominal pain, gassiness, bloating, and changes in bowel habits -- constipation, diarrhea, or both. IBS is also known as "spastic colon" and is easily confused with ulcerative colitis but does not cause bleeding.
Like ulcerative colitis, Crohn's disease causes inflammation in the colon wall, but it can also inflame other organs, including the small intestine and upper digestive tract. Other symptoms include fever, anemia, and sometimes more serious complications, such as intestinal blockage.
