I Have Had Gastrointestinal Problems For Years & Have Managed

I have had gastrointestinal problems for years & have managed it with my diet, recently it's gotten much worse with chronic abdominal pain and diarrhea. I've been told aloe Vera juice will help, but it can cause diarrhea. Should I try it? Does the diarrhea persist or does it stop as the body gets used to it?
