What role does hydration play in preventing constipation?

Hydration plays a crucial role in preventing constipation primarily by facilitating stool passage. Adequate fluid intake helps to soften stool, making it easier to move through the intestines. When the body is well-hydrated, the colon absorbs less water from the stool, which results in softer and bulkier stool. This promotes regular bowel movements and helps to prevent the hardening of stool that leads to constipation.

In contrast, dehydration can lead to harder stools, making them more difficult to pass and increasing the likelihood of constipation. Staying hydrated encourages optimal digestive function and maintains the right balance of electrolytes and fluids necessary for proper bowel motility. This is why hydration is often recommended as part of a strategy to prevent constipation.
