title: Physiology and organ-related pathology of the elderly: stomach ulcers.
abstract: Peptic ulcer disease, particularly as a result of its complications, is a burden that is focused on the elderly through their higher Helicobacter pylori prevalence and use of non-steroidal anti-inflammatory drugs (NSAIDs). In these patients, senescence may further increase ulcer susceptibility, particularly in the stomach, by the loss of mucosal protection and repair mechanisms. Age is mainly a marker for the increased prevalence of other complicated ulcer risk factors such as previous ulcer history and use of anti-coagulants, steroids and aspirin. The development of selective cyclo-oxygenase inhibitors (coxibs) has reduced the specific risk of NSAID ulceration, but the residual incidence in high risk patients remains substantially higher than that in young patients without other risk factors. The argument for early surgery versus endoscopic therapy in high risk patients with bleeding ulcers has not been resolved, both having a high mortality. There is still potential for the development of new strategies to prevent primary and secondary ulcers, either by new drug development or by expanding existing co-prescription strategies.
