    Default Equine Ulcer Diagnosis

    Interesting video on Equine Ulcer Diagnosis

    As I posted on the other thread that popped up with the same video--it looks to me like the pinto horse is conditioned to pop its head around expecting a treat when the pericardial point is palpated. He's happy, ears up, putting his nose right into the vet's hand. The buckskin horse also looks like he's been conditioned and is irritated by the whole process. Once the vet is done standing by his side he's got his ears up, looking casually around.

    I daresay this is a lot like the FEI's current obsession with examining horses to see if "irritating substances" or "sensitivity" are present. Mash on a horse's leg 50 times and it's going to be grumpy about the process. Poke a horse on its tummy or shoulder enough times and it's going to do something to make you stop.

    Whether these two subjects are just being used as examples of "how a horse might react when these spots are touched" or whether they actually have documented ulcers is not clear in the video. I remain, to nobody's surprise, unconvinced by this video as to whether this technique has merit in the real world, and to what degree these diagnostic maneuvers are proven sensitive and specific. It would not be that hard to make that assessment, actually--wish some enterprising vet student would do so!

    And although the presenter is a vet, I am a little uncomfortable with his saying that he would only treat with omeprazole for short periods (he mentioned 10 days) and then (presumably) just stop it when generally it is used for 30 days and most GI specialists I know recommend that the drug is weaned after treatment to prevent rebound acid hypersecretion. I am also not convinced of the wonders of "digestive support supplements".

    What is rebound acid hypersecretion please? And what effect does it have on the horse? I ask because my horse has twice had 11 days of gastrogard (6 months apart) which has made her worse both times not better.

    Briefly, when acid secretion is turned off, the body tries to find ways to turn it back on. When omeprazole is used for a period of time, the hormone gastrin is increased to try and get acid levels back up. (our bodies often don't go along with our meddling witihout a battle) Now you have a situation where gastrin (a hormone that enhances acid secretion) levels are abnormally high. Take away the acid blocker and suddenly you have an animal with sky-high gastrin levels and nothing left to turn off the acid. Rebound acid hypersecretion. Not ideal in a case of ulcers that aren't healed.
