Effect of thyroid hormones on stress ulcer formation.

Background: Stress ulcers are gastric mucosal lesions that may cause life-threatening upper gastrointestinal bleeding. Although it is known that hyperthyroid status prevents stress ulcer formation, the effect of thyroid hormones given just as the stress is beginning has not been studied. The aim of this study was to assess the effect of thyroid hormone supplementation on gastric stress ulcers at the beginning of the restraint stress.
