A case of duodenal bulb ulcer formation in a soldier of theukrainian armed forces during ammunition loading

Conclusions: Stress associated with participation in military operations led to the active reproduction of Helicobacter pylori infection and, accordingly, an increase in "residual" ammonia in the stomach cavity. Heavy physical exertion, which was accompanied by a sharp contraction of the muscles of the anterior abdominal wall, created a "bellows" effect, which concentrated the "residual" ammonia in the cavity of the duodenal bulb and led to the formation of an ulcer.
