@avande welcome to Mayo Clinic Connect. Is hypomagnesia low in magnesium? I’m not sure. About 21 years ago (I’m old) I had bouts of low calcium, magnesium and potassium after I had a pancreas transplant. I had to take supplements of these things for awhile. It is good that you have an appointment coming up soon at Mayo. They will take good care of you. Maybe some other members that have had similar experiences to you will join in soon with input.
