Question

Diarrhoea is associated with A. Surgical removal of the parasympathetic innervation of the colon B. Rectal prolapse and colonic obstruction C. Increased water absorption in the colon D. Lactose intolerance resulting in decreased absorption of solutes in the ileum

Answer 1

Diarrhoea is most directly associated with lactose intolerance, which causes disrupted absorption in the ileum and can lead to increased fluid in the bowels. Other listed conditions are not typically linked to diarrhea.

Step-by-step explanation:

Diarrhoea is often associated with conditions that prevent the adequate absorption of water in the colon. It typically results from a failure to remove enough water from feces, which can be caused by bacteria affecting water reabsorption proteins in the colon or inflammation that impedes the colon's ability to function properly. Of the given options, lactose intolerance leading to decreased absorption of solutes in the ileum is the most directly associated with diarrhea. Lactose intolerance can disrupt normal absorption processes and lead to increased fluid in the bowels, resulting in diarrhea. On the other hand, surgical removal of the parasympathetic innervation of the colon, rectal prolapse, colonic obstruction, and increased water absorption are all more often associated with constipation or other digestive problems, not diarrhea.
