"I'm a 51 year old health professional. In 1983 at the age of 17 I had my gallbladder removed (cholecystectomy). Although my painful gallstone attacks ended, like others I began suffering irritable bowel symptoms for the next 25  years. These frequent bouts of cramping and urgent diarrhea impacted my work, travel and social life. In 2010 I changed my GP and he recommended the off-label use of Wechol as a solution to my GI problems. I cannot overemphasize the profound and positive impact this drug has had on my lifestyle. If you've had your gall bladder removed and are having GI problems, please talk with your doctor about this medication."
