My Sister, age 66, has been experiencing bowel movements that are extremely loose, explosive and somewhat inconsistent in appearance....sometimes like coffee grounds, other times like applesauce, etc. and the urge is very unpredictable and when she gets the urge, she has to go immediately. She has been examined by a gastro-enterologist and had a colonoscopy a year ago that was clear. He sent the feces to a lab to be checked for bacteria and virus with lab work coming back clear. She said she took a list of her Rx's and supplements to him and he said they were fine. I am really worried about her as she is under significant stress and has been for quite some time. I would sincerely appreciate any thoughts or advice you have.
