What is a common side effect of increased fiber intake in elderly clients?

1. Diarrhea

2. Flatus

3. Nausea

4. Bloating

The correct answer is: Flatus

Increased fiber intake is known to enhance digestive health, but it can also lead to certain side effects, especially in elderly clients who may not be accustomed to a high-fiber diet. Flatus, or gas, is a common outcome of dietary fiber consumption. This occurs as fiber is fermented in the intestines by gut bacteria, leading to the production of gases like hydrogen, methane, and carbon dioxide. For elderly individuals, their digestive systems may respond differently to sudden increases in fiber, which can lead to an increase in intestinal gas. Additionally, fiber can help improve bowel regularity, but the gases produced during digestion can provoke discomfort and can be more noticeable in this population group. While other issues such as diarrhea, nausea, and bloating can occur depending on the individual and the type of fiber consumed, flatus stands out as a frequent and typical response observed due to the fermentation process. Managing fiber intake gradually can help minimize discomfort, but flatus remains a relevant side effect linked with increased fiber consumption.
