Explanation:

Stress can lead to elevated levels of gastrin. Gastrin stimulates stomach - acid production, and excessive acid can contribute to the formation of stomach ulcers, which is a major side - effect on the gastrointestinal system. Options C and D involve cortisol and are more related to overall body weight and eating behavior rather than direct gastrointestinal effects. Option A about diminished gastrin leading to constipation is not a typical major stress - related gastrointestinal effect.

Answer:

B. elevated levels of gastrin, causing stomach ulcers
