During an allergic reaction, which gastrointestinal change is most likely?

• A. Hypomotility
• B. Hypermotility
• C. Bowel status
• D. Slowing and constipation

Answer: (B)

When an allergic reaction occurs, mast cells release mediators like histamine that stimulate the gastrointestinal tract, causing smooth muscle contraction and increased peristalsis. This results in hypermotility, so the intestines move contents more quickly, often with cramping or diarrhea as the gut speeds up. Hypomotility or slowed movement wouldn’t fit these mediator effects, and “bowel status” is too vague to capture the specific change.
