Irritable bowel syndrome (IBS) is the most commonly diagnosed gastrointestinal disorder, accounting for 25 to 50 percent of all referrals to gastroenterologists. The exact cause is unknown, but researchers at the Institute of Human Genetics in Heidelberg, Germany have discovered a genetic mutation in serotonin receptors of the intestinal tract that may cause the diarrhea which many people with IBS experience. Serotonin is a hormone that is found not only in the central nervous system, but in large abundance in the GI tract. A mutation in a receptor for serotonin can explain GI disturbances, such as diarrhea. This discovery will likely pave the way for future treatments of IBS.

I found this article very interesting because it expresses information which correlates with my own condition of IBS + insomnia + elevated blood pressure. I would be interested in receiving information regarding any further information resulting from research of the issues involved.

I found my IBS has to do with food allergies and stress. I found the food allergies through a blood test. Stress is related to job. I’ve changed my job and now try to stay away from food that trigers IBS. My change of diet has made a big difference!

My IBS actually seems to have gotten worse after spinal surgery to remove a cyst. I was hoping it was affecting digestive nerves…
