Final answer:
Excessive colonic response to meals, GI hormones, and stress is characteristic of irritable bowel syndrome (IBS), a disorder differentiated from inflammatory diseases like Crohn's disease and ulcerative colitis.
Step-by-step explanation:
The excessive colonic response to meals, gastrointestinal hormones, and stress is characteristic of irritable bowel syndrome (IBS). IBS is a chronic gastrointestinal disease that is treated with the neurotransmitter serotonin. It is associated with a range of symptoms like abdominal pain and altered bowel habits without any clear cause. Unlike inflammatory bowel disease, such as Crohn's disease or ulcerative colitis, where the immune system attacks the digestive system leading to inflammation, IBS does not cause inflammation or changes in bowel tissue and is often related to stress.
