    Irritable Bowel Syndrome

    Bad Connections continued...

    In one sense, Brunner is lucky — she knew what was troubling her and she (finally) got effective care. "Many doctors still don't recognize IBS as a real condition," says Lin Chang, M.D., co-director of the UCLA Center for Neurobiology of Stress. Lots of women are in the dark as well: A survey of 5,009 adults found that as many as 76 percent of IBS sufferers may be undiagnosed. Which also means they're not getting the help that could change their lives.

    Bad Connections

    Though it's not known for sure, experts believe that when you have IBS, there's a breakdown in the normal communication between your gut and your brain. Nerves in your GI tract shoot pain signals to the brain when there's nothing really wrong — just a little gas passing through, for instance. Or garbled messages may get sent from the brain to the muscles in the intestines, causing them to overcontract so food is forced through with lightning speed, triggering diarrhea. In other cases, muscle contraction slows almost to a standstill, leading to constipation.

    Genes seem partly to blame for these faulty links. Hormones probably play a role, too; women with IBS outnumber men about two to one. What is clear: Though your intestines don't work right when you have IBS, they look perfectly normal if they're checked with X-rays, ultrasounds, or colonoscopies. That's why a battery of tests isn't necessary for a diagnosis — just a good medical history and physical exam — concludes a recent report from the American College of Gastroenterology.

    Your symptoms are considered IBS if you have pain with bothersome bowel habits lasting for at least three months. Not every day will be bad. The ups and downs are determined, in good part, by how stressed you are, what you eat, and your menstrual cycle — about 70 percent of women say their IBS gets worse around their periods. Identifying your triggers is a crucial step to reducing flare-ups. But there are also many other ways to help yourself.

    Going Natural

    There are a number of Rx medications for IBS, but they work only about 30 to 40 percent of the time, says Gerard E. Mullin, M.D., director of Integrative GI Nutrition Services at the Johns Hopkins Hospital in Baltimore. Plus, "some have serious side effects," he adds. No wonder alternative therapies have gained experts' attention — research is finding that they can be highly effective. They're safe to try on your own, either individually or several at once.
