In _____ constipation, peristaltic movement in the intestines slows down because of the weakness of intestinal muscle.

Question

Accepted Answer

In atonic constipation, peristaltic movement in the intestines slows down because of the weakness of the intestinal muscle. This condition is characterized by a lack of muscle tone in the intestines, which leads to reduced motility and slower movement of stool through the digestive tract. Atonic constipation is often associated with factors such as a sedentary lifestyle, inadequate dietary fiber, and insufficient fluid intake, all of which can contribute to weakened intestinal muscles.

Now, let's examine why the other options are incorrect:

2. Spastic: Spastic constipation is characterized by increased muscle tone and spasms in the intestines, which can lead to irregular bowel movements and difficulty passing stool. Unlike atonic constipation, spastic constipation involves hyperactivity of the intestinal muscles rather than weakness.

3. Obstructive: Obstructive constipation occurs when there is a physical blockage in the intestines, such as a tumor or stricture, that prevents the normal passage of stool. This type of constipation is not related to the weakness of intestinal muscles but rather to an obstruction that impedes movement.

4. Psychological: Psychological constipation is related to mental or emotional factors, such as stress or anxiety, that can affect bowel habits. It does not involve the physical weakening of intestinal muscles but rather the influence of psychological factors on bowel function.

In summary, atonic constipation is the correct answer because it specifically involves the slowing down of peristaltic movement due to the weakness of intestinal muscles, distinguishing it from the other types of constipation listed in the options.
