Why are older individuals at increased risk for constipation?

1. Lack of physical exercise

2. Higher metabolism rate

3. Slower movement of food through the digestive tract

4. Increased water intake

The correct answer is: Slower movement of food through the digestive tract

Older individuals are indeed at increased risk for constipation primarily due to the slower movement of food through the digestive tract. As people age, their digestive system may slow down, which can lead to longer transit times for food. This means that food stays in the intestines longer, allowing more water to be absorbed from the stool, which can result in harder and drier stools that are more difficult to pass. Factors such as decreased physical activity, changes in diet, and certain medications can also contribute to this issue. However, the slower movement of food is a key physiological change associated with aging that significantly influences bowel health.
