Dr. Google says that Hypoclacemia is low calcium, and that up to 20% of folks have it. I don't know that I have it. I probably would qualify as having IBS, but haven't talked to a doctor about it. I was pretty sick for a few days just last week and I'm not sure which of two fast food items triggered it. Maybe it was simply the combination of the two. I get IBS like symptoms when I eat excess fat or sugar or with my period or when I'm nervous. So a lot. For this recent episode I used ginger, but mainly suffered through it. Yesterday I had migraine symptoms (which for me includes nausea) and a magnesium supplement (Yerba Mate tea for me) nipped it in the bud. Sorry for the discomfort.
