The gut and brain communicate through nerves, hormones, immune signals, and the microbiome. Stress can alter intestinal movement and sensitivity, leading some people toward urgency and loose stool and others toward constipation.
What to keep in mind
A short record of symptoms, sleep, meals, and stressful events may reveal patterns. Slow breathing, regular movement, consistent meals, and adequate sleep can support regulation, though they are not cures for disease.
Do not assume every symptom is stress. Persistent or severe changes deserve medical evaluation, particularly when warning signs are present.
