I have been diagnosed with this. The Dr's said my calcium and magnesium was very low which caused this condition. I take calcium/magnesium supplements on a daily basis. I am hypocalcimic, having no parathyroid glands. The only relief I get is diarrhea. Any help is deeply appreciated. Note, I have also had major intestinal surgery in the past and lost part of my large and small intestines. I do take high doses of calcium/magnesium/zinc supplements and high doses of calcitiol due to this condition.
