Stress can have a significant impact on digestive health, often leading to loose watery bowel movements. Psychological stress activates the gut–brain axis, increasing intestinal motility and altering fluid absorption in the intestines. Hormonal changes, particularly elevated cortisol, can further disrupt normal bowel function, triggering diarrhea-like symptoms even in the absence of infection. Chronic stress may also worsen underlying conditions such as irritable bowel syndrome. While management typically focuses on stress reduction and dietary adjustments, infectious causes should be ruled out. In clinical and pharmaceutical contexts, products sourced from a reliable nitazoxanide wholesaler are often considered when protozoal infections are suspected as contributing factors.
