Got the dreaded "flu", gastroenteritis. MassI've diarrhea for 3 days. No vomiting but unable to eat or drink . Voice began to change. Kind of hoarse. Have always had some shortness of breath so hard to gage if worse. Decided to go to E.R. Needed fluids. Doc ordered various blood tests. Results showed greatly reduced potassium.I told him I don t usually sound like this and it is not a good sign with myasthenia gravis. He ordered potassium pills and potassium I.V. Said M.G. improves if potassium is low (also a big help with my chronic renal disease). Voice became normal within 5 minutes. I did spend overnight in step down I.C.U. but after more I V s was discharged later that day. I said I think k my CRD helped my M.G. Either way it appeared my crisis was averted.
