Cortisol is a hormone produced by the adrenal glands, located on top of your kidneys. It plays a key role in helping your body respond to stress and maintain various bodily functions. Here’s a closer look at what cortisol is, its effects on your health, and how you can manage its levels.
What is Cortisol?
Cortisol is often referred to as the “stress hormone” because its levels rise in response to stress and low blood sugar. It helps regulate various functions, including:
- Metabolism: Cortisol helps control how your body uses fats, proteins, and carbohydrates.
- Immune Response: It has an anti-inflammatory effect, helping to regulate the immune system.
- Blood Pressure: Cortisol helps maintain blood pressure by affecting the function of your blood vessels.
How to Tell if Cortisol is Elevated
Elevated cortisol levels can manifest through various symptoms, including:
- Fatigue and Insomnia: Persistent tiredness or difficulty sleeping.
- Weight Gain: Especially around the abdomen.
- Mood Changes: Increased irritability or anxiety.
- Digestive Issues: Problems such as bloating or indigestion.
Negative Effects on the Body
Chronic high levels of cortisol can negatively impact your health, leading to:
- Cardiovascular Problems: Increased risk of high blood pressure and heart disease.
- Weakened Immune System: Higher susceptibility to infections.
- Bone Health Issues: Risk of osteoporosis and bone fractures.
- Mental Health Concerns: Anxiety, depression, and cognitive difficulties.

Certain factors can cause elevated cortisol levels, including:
- Stress: Emotional, psychological, or physical stress can raise cortisol.
- Poor Sleep: Irregular or insufficient sleep patterns.

Maintaining balanced cortisol levels is crucial for both short-term well-being and long-term health. Proper regulation helps ensure that you can manage daily stress effectively, support your immune system, and maintain overall physical and mental health.
Discussing Cortisol with Your Healthcare Provider
If you suspect that your cortisol levels may be off, discuss your symptoms and concerns with your healthcare provider. They may recommend specific tests to measure your cortisol levels, such as:
- Blood Tests: Measuring cortisol levels in the blood.
