Mind and gut: the link between low mood and slow bowels

Depression and Digestive Health: A New Link Between Mood and the Gut

People often say that stress can upset the stomach, but scientists are digging deeper to see how feeling down might slow digestion.

A recent study examined adults living in a northern region of Iran to determine whether depression is associated with an increased risk of constipation. The researchers drew on data from a large cohort of volunteers who had been followed for health research and asked each participant about their mood and the frequency of hard or painful bowel movements.

Key Findings

• Individuals reporting depressive symptoms were more than twice as likely to complain of constipation compared with those who felt mentally better.
• The connection is biologically plausible: depression can alter stress hormones and nerve signals that regulate intestinal muscle contractions, making stool harder to pass.

Clinical Implications

• Doctors should consider screening patients with constipation for mental health issues.
• Simple interventions—such as dietary adjustments or regular exercise—may benefit both mood disorders and digestive problems.

Understanding this two‑way relationship between mind and bowels could pave the way for more holistic care strategies.
