Signs and symptoms associated with anaphylactic reaction that involve the stomach may include all of the following EXCEPT:

Anaphylactic reactions can lead to a variety of signs and symptoms, particularly affecting the gastrointestinal system. During anaphylaxis, the body releases histamine and other chemicals that can result in abdominal pain, cramping, and increased gastrointestinal activity, leading to symptoms like diarrhea. Loss of bowel control can also occur as a result of severe gastrointestinal distress associated with anaphylaxis.

Cyanosis, on the other hand, is primarily a result of inadequate oxygenation of the tissues and is generally tied to respiratory or circulatory issues rather than gastrointestinal symptoms. Therefore, it is not directly associated with the stomach or gastrointestinal manifestations during an anaphylactic reaction. This distinction highlights why cyanosis is the correct choice, as it is not a symptom related to gastrointestinal involvement in this context.
