Questiond about your blood sugar??
The Stress Hormone Cortisol and Blood Sugar | Dr. Hagmeyer
Stress significantly impacts blood sugar by triggering the release of hormones like cortisol and adrenaline, which prompt the liver to release stored glucose for energy (the "fight-or-flight" response), leading to higher blood sugar levels, especially in people with diabetes. Chronic stress worsens this by causing sustained high blood sugar, insulin resistance, and can lead to behavioral changes like poor eating or skipping medication, making diabetes harder to manage, though it can sometimes cause drops in blood sugar as well.
How Stress Raises Blood Sugar
Hormonal Release: Stress activates the "fight-or-flight" response, flooding your bloodstream with adrenaline and cortisol.
Energy Mobilization: These hormones signal your liver to release stored glucose (sugar) into your blood to provide quick energy for perceived threats.
Insulin Resistance: Stress hormones can also make your body's cells less responsive to insulin, meaning glucose can't enter cells efficiently, further raising blood sugar.
Indirect Effects of Stress
Behavioral Changes: Stress can lead to unhealthy coping mechanisms, such as overeating, eating junk food, exercising less, or forgetting medications, all impacting blood sugar.
Sleep Loss: Lack of sleep, often a result of stress, can also worsen insulin sensitivity.
Impact on Diabetes Management
For Type 2 Diabetes: Stress typically increases blood sugar, making it harder to control.
For Type 1 Diabetes: Stress can cause unpredictable spikes or drops in blood sugar.
Long-Term: Persistent high blood sugar from chronic stress increases the risk of diabetes complications.
Managing Stress & Blood Sugar
Monitor: Keep a log of stress levels and blood sugar readings to see patterns.
Exercise: Regular physical activity helps manage stress and improve glucose control.
Relaxation: Practice relaxation techniques like deep breathing or mindfulness.
Healthy Habits: Maintain a balanced diet, get enough sleep, and stick to your diabetes care routine.
Seek Support: Talk to your healthcare team; stress management is a key part of diabetes care.
