Excessive Drinking and Urination, Confused and Concerned
My wife's 10 year old EMS/IR gelding Mustang, Shiloh has been drinking and urinating A Lot! for the about the past 6 weeks or so. I read in the 'overview brochure' that this is a sign of Advanced EMS and PPID.
I guess I'm confused/concerned with the arrival of a new 'advanced ems symtom' as I was thinking we were making progress. Any Ideas on what might be going on ? Looking for Feedback, possible paths to explore.
He was sore and lame with Laminitis some in 2018-2019, but Over the past year on dry lot with tight diet control and new vet/farrier he has lost over 200 lbs and is at what I would consider pretty much ideal weight (~870 lbs on weight tape at 14 hands), and he's been comfortable and 'sound' for 9-10 months, athough we are proceeding cautiously with exercise at this point.
DVM first impression is that he is just drinking a lot due to the heat, but I'm not sure about that.
His only ACTH Test was in January of this year and it was 18.9 pg/ml. (w/overnight fasting)
His Insulin at that time was 35Ulu/mi and Glucose was 98 mg/dl (w/overnight Fasting)
His latest Bloodwork: Insulin: 21.58, Glucose:93 (non-fasting. although he did not have 100% constant access to hay and he did eat 1/3 lb of ration balancer about 1.5 hours prior to the blood draw)...
I know these numbers still indicate uncompensated IR, but hoping to get in the safer zone as able to increase exercise.
Metformin (DVM is likely going to take him off this at next visit)
1 scoop Thyro-L
Prescend 1 tablet
