Merry Christmas everyone! Hope you and your furry babies are enjoying some great time together and stay safe! 2020 has been tough, especially when it closes to the holiday season. My baby boy- Casper, (16) just being diagnosed with hyperglycemia on 12/20/2020. He had been an extremely healthy and active boy for his entire life until end of September that we noticed he had some gum problem. The vet ended up took out 3 teeth out of him and he has never acts the same from that point. He drinks a lot of water, still being EXTREMELY picky with food and lost weight significantly. We ended up took him in to the vet again on 12/17/202, his glucose read: 538 mg/dl. Regardless how upset I was (he was a very heathy baby when we first took him in for the gum/teeth problem, all test and numbers came back great), we had him hospitalized for 2 days and took him home with all the supplies before Christmas. We followed all the protocols, OCD being like on the insulin injection time and feeding (ProPlan DM). I started testing his BG on the 23rd. Quite unexpected, instead of seeing it being regulated, Casper's BG raised from 511 mg/dl (first reading from 23rd) to 683 mg/dl (last reading at 10:02 AM PDT, without any food, after 1 unit of VetSulin at 9:00 AM). I really don't know what is going on, Casper was responding to VetSulin at the vet, they got his BG regulated at 149 mg/dl before discharge him. And now, seems with all those injections (my poor baby)... the insulin is obviously doing absolutely NOTHING. If anyone who is experienced in this type of situation, please kindly advise!
