Update:
The old man has been on the stomach coating meds for 2 weeks now, and I hate to say it, but he has not had a colic episode going on three weeks this coming Wednesday. However, this afternoon I got home from work and he wasn’t outside. He has free choice access to his stall and run in area. I quickly parked my car and went to the barn, to find him laying down in his stall. Not flat out, but just laying with his head up. He popped up when he saw me and acted “fine”. After saying hello, he went back outside and starting munching on some hay. I’m not quite sure what to make of that. He’s not normally in his stall laying down, however he didn’t act painful either. I guess I will keep a close eye on him.
We are to continue the stomach coating meds, holding off on steroids for now. His vet here at home feels like the steroids may make his suspected hind gut ulcerations worse. He said if he does poorly going forward we can try them as a last ditch effort. He also had a talk with me about trying him off hay completely for awhile and moving to an increased complete feed and soaked, pelleted hay. OSU biopsies were “inconclusive” meaning, they didn’t find anything worth noting and couldn’t rule in or out IBD or Lymphoma of the GI tract.
His attitude, and energy has been night and day difference compared to almost three weeks ago. His appetite is good too. He looks to be gaining some weight back as well. I am hopeful we are on the right track with him, and I wanted to thank everyone for all their suggestions, it helps even, to know I’m not the only horse owner to deal with these frustrating symptoms.
