Your gut does far more than digest food—it plays a powerful role in how you feel every day. Researchers often call it the “second brain” because of its direct communication with the brain through the gut-brain axis. When your gut is out of balance, your mood can shift in ways that feel confusing or unexpected. Many people overlook these subtle signs, brushing them off as stress or lack of sleep. Understanding how gut health and mood are connected can help you take control of both your mental and physical well-being.
