hi I am a diabetic and I have been taking the drug invokana. but not with in the last month I have been reading about ketoacidosis related to the drug. I have been having at least four of the systems to this ketoacidosis. I went to the dr. yesterday with systems of a rash all over my body. but I also asked about the lost of appetite. they r wanting me to go have a ultra sound on my stomach will that possibly show any results of possibly having this ketoacidosis?
