Has anyone had a horse founder from and insulin problem?

Horses do get insulin problems, I think similar to diabettes, for example horses with cushings often have abnormal levels of insulin which can cause laminitis. I think with your horse, if you're concerned then have an experienced horse vet come out and check him.

not my horse but another at the place where i board at, she can not have any sugar, she has insulin resistance, they have to get a special no sugar feed for her, and if she gets too much sugar then she can founder. she can't have any apples, carrots, or sugar(natural or unnatural) stuff, she can have sugar free candies and mints though. there was a pony that we were looking at to buy a year ago or so and she had something called PSSM, its like insulin resistance but way worse, no sugar at all, special feed, lots of turn out in a non-grassy arena, prone to colic also prone to tieing up. hope this helps♥

Sounds like cushing's disease. If the horse has foundered keep it in the stable as exercise makes it worse til the vet says it can go out. Feed unmolassed sugar beet if horse has sugar beet bucket feed for horses and ponies prone to laminitis eg Dengie hi fi lite Spillers hi fibre cubes, spillers happy hoof, Allen and Page's L mix Dodson and Horrell safe and sound, and soak or steam his hay to get the sugar out. Yes I lost my pony to cushing's he foundered and was very weak near the end. Just lost my sister's pony to cushing's she had laminitis in the past, but she managed to control it with diet management. Your horse will need a grazing muzzle when he's allowed back out.

There is a horse at my barn whose laminitis 5 years ago was brought on, in part, by his Cushing's disease. He's a very old horse -- 35 or so -- and the barn manager monitors his diet obsessively, but he's been OK since then. Sorry to hear about your guy; I would try to get a different vet just this once who could come out TODAY!
