What common factor can contribute to constipation?

Stress and sympathetic nervous system activity play a significant role in contributing to constipation. When an individual experiences stress, the body's stress response activates the sympathetic nervous system, which can slow down bowel motility. This means that the normal contractions of the intestines may be reduced, leading to delayed transit time and increased difficulty in passing stools.

In situations of heightened stress, individuals often find themselves in a "fight or flight" mode, which prioritizes survival functions over digestive functions. Therefore, the gastrointestinal system may slow down, resulting in the common issue of constipation. Recognizing the importance of managing stress can help alleviate this condition by allowing for better digestive function.

The other factors listed, such as overconsumption of fiber, high hydration levels, and regular physical activity, typically promote regular bowel movements rather than contribute to constipation.
