How does aging typically affect the digestive system?

1. Increased saliva production

2. Faster digestion speeds

3. Slower intestinal motility

4. Increased production of gastric acid

The correct answer is: Slower intestinal motility

As individuals age, various physiological changes occur in the body, and the digestive system is particularly affected. One significant change is slower intestinal motility. This means the movement of food through the digestive tract can become less efficient, leading to delays in the passage of food and an increased likelihood of digestive issues such as constipation. The aging process can lead to a decrease in the strength and frequency of muscle contractions in the intestines, which contribute to this slower motility. Additionally, the body's overall metabolism can slow down, further impacting digestion. Understanding the effects of aging on the digestive system is crucial for caregivers and healthcare professionals, as it helps them recognize potential problems and implement appropriate interventions to support the digestive health of older adults. The other options involve processes that typically do not increase or improve with age; rather, they tend to either remain stable or decline.
