Ulcer, Gastro-Duodenal, Glandular Antral or Duodenal Ulcer (in Adult)

This condition has a different pathologic origin than EGUS (classic Equine Gastric Ulcer Syndrome).

Ulceration and inflammation in the outflow part of the stomach (antrum or pylorus of the stomach) is not as common as EGUS but is more common than previously suspected.

This can only be diagnosed with a 3 meter gastroscope. Diagnosis requires more manipulation of the scope to reach this area. This diagnosis is possible for a horse with undiagnosed chronic recurrent low-grade colic.


Feed multiple times per day versus fewer larger feedings and provide your horse with frequent turnout.

All factors considered to improve gastrointestinal health including increased turnout, increased long stem roughage, decreased grain.

Alfalfa has been found to somewhat reduce stomach acidity and so may be beneficial. Dietary oils like corn oil may have a mild protective effect.
