The human body has a remarkable way of sending signals when something feels overwhelming. Sometimes those signals come as headaches, racing thoughts, or trouble sleeping. Quite often, they arrive through the stomach.Many people have experienced "butterflies" before a big event. Others notice bloating, acidity, nausea, constipation, or loose motions during stressful periods. These reactions are not imaginary. They are biological responses happening in real time.Dr Sukirti Misra, Consultant Endocrinologist at KIMS Hospitals, Thane, explained, "Stress affects the mind and the digestive system directly. The gut and brain are closely connected through the 'gut-brain axis.' When a person is stressed, the body releases hormones like cortisol and adrenaline. These hormones can disrupt normal digestion. Blood flow shifts away from the digestive tract, stomach acid production may change, and bowel movements can become irregular."Researchers have spent years studying this connection. The National Center for Complementary and Integrative Health (NCCIH), part of the US National Institutes of Health, notes that stress triggers the body's "fight-or-flight" response and can contribute to or worsen digestive disorders.The gut is not simply a food-processing machine. It is in constant conversation with the brain.
