i have loose stools everyday, heartburn sometimes and more burping than usual. Before this I had nausea, vomiting and loss of appetite, which eventually went away. Now I just have the previously described symptoms. Sometimes my stomach gurgles and I feel extremely hungry all of a sudden, not at the same time. Sometimes I feel normal. I am 63 years old, with osteopenia and have been told that I am pre-diabetic. I take calcium with vitamin d and magnesium, sometimes powdered calcium and biotin for skin and nails.
