I have multiple digestive issues and I am trying to narrow down the cause. Here are the symptoms: Acid Reflux, gas and bloating, abdominal cramping, diarrhea, constipation. I have had colonoscopies. The last came up with a polyp that was removed and benign. Just don t know if I am looking at Lactose Intolerance, a form of IBS, Crohns, etc.
