Cortisol, a hormone produced by adrenal glands located on top of the kidneys, plays a crucial role in various body functions such as metabolism regulation, inflammation reduction, and stress response promotion. While essential for health, chronically elevated cortisol levels can lead to numerous problems.
Increased cortisol levels can occur due to factors like Cushing’s syndrome from long-term use of synthetic cortisol-containing steroid drugs or tumors in the brain or adrenal glands causing excessive cortisol production.
There are several indicators of elevated cortisol levels:
Weight Gain
High cortisol levels can lead to weight gain, particularly around the abdomen. Cortisol influences fat storage, causing more fat to accumulate in that area. While this is true for both genders, hormonal variations can affect distribution.
Other factors like diet, lifestyle, genetics, and hormonal imbalances such as insulin resistance also contribute to increased abdominal fat. Signs may include fat accumulation in the neck and shoulders (buffalo hump) and a rounded, swollen face.
Fatigue and Insomnia
Despite feeling tired, individuals with high cortisol levels often experience sleep disturbances, leading to chronic fatigue. Disrupted cortisol circadian rhythm affects sleep patterns negatively.
High Blood Pressure and Blood Sugar Levels
Elevated cortisol levels can increase blood pressure and blood sugar levels over time, raising the risk of hypertension and diabetes.
Mood Changes
Cortisol, known as the stress hormone, can induce anxiety, depression, and irritability by affecting brain neurotransmitters like serotonin and dopamine.
Bone Weakness
Prolonged high cortisol levels can cause muscle atrophy, loss of bone density, and increase the risk of osteoporosis, especially in postmenopausal women.
Other Symptoms
Additional symptoms may include bruising-prone skin, large purple stretch marks, low sex drive, and fertility issues.
