Clinical signs and clinical significance

Equine gastric ulcer syndrome (EGUS) has been associated with a variety of clinical signs in adult horses. Unfortunately, most of the information is anecdotal, with very little robust scientific evidence to support an association between perceived clinical signs of EGUS and the presence or absence of a specific type of lesion seen on gastroscopy. Reporting clinical signs of EGUS and trying to establish clinical significance is complicated. Most of the clinical signs associated with EGUS are nonspecific and are often subjective and owner-perceived. This is complicated further by the fact that a large proportion of horses with EGUS will not demonstrate clinical signs. In addition, horses with equine glandular gastric disease (EGGD) and equine squamous gastric disease (ESGD) will often manifest with different clinical signs, and to date there has been no attempt to differentiate between EGGD and ESGD when reporting clinical signs ...
