What problem may arise if a patient does not have enough fluids?

Insufficient fluid intake can lead to dehydration, which poses several health risks, one of which is constipation. When the body lacks adequate hydration, the intestines absorb more water from the waste material as it passes through, which can result in harder, drier stools that are more difficult to pass. This can create discomfort and lead to straining during bowel movements.

In contrast, weight gain or overhydration are typically associated with excessive fluid intake, not deficiencies, and nausea may arise from a variety of factors unrelated to fluid status. Therefore, highlighting constipation as a consequence of inadequate fluid intake underscores the importance of hydration for maintaining healthy bowel function.
