Stress, Cortisol and Blood Sugar: How Stress Raises Glucose and What Helps

The mind-body link behind unexplained blood sugar changes.

Quick answer

Stress raises blood sugar through the hormones cortisol and adrenaline, which signal the liver to release stored glucose for quick energy. Short-term this is normal, but chronic stress keeps glucose and cortisol elevated, can reduce insulin sensitivity, disrupts sleep and drives cravings for sugary comfort foods. Regular exercise, slow breathing, time outdoors, social connection, good sleep and limiting caffeine and alcohol help manage stress and support healthier blood sugar.

Key takeaways

If your blood sugar seems higher during stressful weeks, even when you're eating well, stress hormones may be the reason.

How stress affects glucose

Fight or flight

Adrenaline and cortisol tell the liver to release glucose so your muscles have quick fuel.

Chronic stress

When stress doesn't switch off, cortisol and glucose can stay elevated, and cells may become less responsive to insulin.

Behaviour

Stress disrupts sleep, reduces motivation to exercise and increases cravings for sugary comfort foods.
