Flatulence, constipation and diarrhea, nausea and stomach cramps: Irritable bowel syndrome (IBS) can turn digestion into a nightmare. Frequent visits to the bathroom are often accompanied by sleep disturbances, headaches, and backaches. In Germany alone, some seven million people are affected by the disorder -- and by the fact that their irritable bowel syndrome is often deemed psychosomatic. This is because the organic trigger of the disease has never been discovered, and consequently the various therapeutic interventions are disappointing for both the patients and their doctors. That may soon change, however, because now, for the first time, biologists in Munich have nailed down hidden physical causes of this bowel disorder.
