Although not a new problem, stomach (gastric) ulcers are a condition that has recently received a lot of publicity, both in our professional journals and in lay publications and magazines. Surprisingly, it has been estimated that up to 50% of all foals will have gastric ulcers and that all horses will have some degree of gastric ulceration at sometime in their life. In one study it was found that 82% of racing Thoroughbreds had stomach ulcers. While these numbers are obviously high, not all horses will show clinical signs of gastric ulceration and in fact most will heal themselves without ever causing the horse an obvious problem. There is a very wide spectrum of severity of these ulcerations from essentially non-significant to life threatening. Various treatments are now available for addressing this condition.
