Quizplus · Accepted Answer

When lactose is not hydrolyzed, it remains in the lumen of the intestine and draws water into the bowel. This creates an osmotic force that pulls water from the intestinal wall, leading to watery diarrhea known as osmotic diarrhea. The other options, motility diarrhea and secretory diarrhea, are caused by different mechanisms such as intestinal inflammation or altered electrolyte transport. Small-volume diarrhea refers to a specific type of diarrhea where the amount of stool produced is decreased, which is not relevant to the scenario described.
