Medical experts have identified a strong link between psychological stress, environmental changes, and gastrointestinal health. Stress can disrupt stomach and intestinal motility, leading to abdominal bloating. This condition is categorized into organic causes, such as ulcers or celiac disease, and functional causes related to movement issues.

Stress also influences dietary habits through emotional eating, where cortisol levels drive a preference for sweet and fatty foods. Furthermore, changes in routine or travel can disrupt gut microbiota, potentially causing bloating and constipation due to shifts in bacterial balance and changes in consumption patterns.
