Review Questions

• How does psychological stress affect gastrointestinal function?
  • Psychological stress affects gastrointestinal function by altering gut motility, increasing intestinal permeability, and changing gut microbiota composition. When an individual experiences stress, the sympathetic nervous system is activated, which can inhibit digestive processes. This may result in symptoms like nausea, bloating, and changes in appetite, demonstrating a clear link between mental state and gut health.
• What role does cortisol play in the relationship between psychological stress and gastrointestinal health?
  • Cortisol plays a significant role in the relationship between psychological stress and gastrointestinal health as it is a hormone released during stress responses. Elevated cortisol levels can lead to inflammation and alterations in gut microbiota, which are associated with various gastrointestinal disorders such as IBS. Thus, managing cortisol through stress reduction techniques can help improve gut health.
• Evaluate the effectiveness of different strategies for managing psychological stress in relation to improving gastrointestinal function.
  • Various strategies for managing psychological stress include mindfulness practices, exercise, therapy, and dietary changes. Research shows that mindfulness meditation can lower cortisol levels and improve gut health by fostering a balanced gut microbiome. Regular physical activity not only helps reduce stress but also promotes healthy digestion.
