What might cause constipation in elderly individuals?

Dehydration is a significant contributor to constipation in elderly individuals. As people age, they often experience a decrease in the sensation of thirst, which can lead to inadequate fluid intake. When the body is dehydrated, the colon absorbs more water from the waste material, leading to harder stools that are more difficult to pass. This physiological response can result in constipation, making it essential for elderly individuals to maintain proper hydration levels to support healthy bowel function.

Factors like increased fluid intake, improved diet, and increased physical activity generally promote regular bowel movements and help prevent constipation, standing in contrast to the impact of dehydration. Therefore, recognizing and addressing dehydration is crucial in managing and preventing constipation among older adults.
