UCLA researchers have described a new form of irritable bowel syndrome (IBS) that occurs after an acute bout of diverticulitis, a finding that may help lead to better management of symptoms and relief for patients.
The discovery of this new condition, called Post-Diverticulitis Irritable Bowel Syndrome (PDV-IBS), validates the irritable bowel symptoms that many patients report long after suffering a bout of diverticulitis, but that many physicians wave off as being part of the original condition, said study senior author Dr. Brennan Spiegel, an associate professor of medicine at the David Geffen School of Medicine at UCLA.
"We've known for a long time that after some people develop diverticulitis, they're a different person. They experience recurrent abdominal pains, cramping and diarrhea that they didn't have before," Spiegel said. "The prevailing wisdom has been that once diverticulitis is treated, it's gone. But we've shown that IBS symptoms occur after the diverticulitis, and it may result from an inflammatory process like a bomb going off in the body and leaving residual damage."
The study appears Sept. 5, 2013 in the peer-reviewed journal Clinical Gastroenterology and Hepatology.
As they age, most people develop diverticulosis, or pouches in the lining of the colon. More than 50% of people over 60 have the condition, but the pouches usually don't cause any problems. Occasionally, the pouches become inflamed, leading to diverticulitis, which causes pain and infection in the abdomen. Doctors usually treat it with antibiotics, or in more severe cases, surgery.
"A major surprise in our study was that diverticulitis patients not only developed IBS at a higher rate than the controls, but they also developed mood disorders like depression and anxiety at a higher rate," Spiegel said. "Because IBS and mood disorders often go hand in hand, this suggests that acute diverticulitis might even set off a process leadin
