If your body produces too much cortisol, you can develop a condition called Cushing's syndrome, leading to a range of characteristic symptoms and health problems.
Signs and Symptoms of Excess Cortisol
Excess cortisol affects many parts of the body and can manifest in several noticeable ways. Here's a breakdown of the common signs:
-
Weight Gain and Fat Distribution:
- Increased fat accumulation, especially in the chest and abdomen, while arms and legs remain relatively slim.
- Development of a "buffalo hump," which is a fat deposit on the back of the neck and shoulders.
- A rounded, red, and puffy face, sometimes referred to as "moon face."
-
Skin Changes:
- Thinning skin that bruises easily.
- Purple or pink stretch marks (striae) on the abdomen, thighs, breasts, and underarms.
- Acne.
- Slow wound healing.
-
Musculoskeletal Issues:
- Muscle weakness, particularly in the upper arms and thighs.
- Bone loss (osteoporosis), increasing the risk of fractures.
-
Blood Sugar and Blood Pressure:
- Elevated blood sugar levels, potentially leading to diabetes.
- High blood pressure (hypertension).
-
Mental and Emotional Effects:
- Irritability, anxiety, or depression.
- Difficulty concentrating.
- Mood swings.
-
Other Symptoms:
- In women, menstrual irregularities or absent periods.
- In men, decreased libido and erectile dysfunction.
- Fatigue.
- Headaches.
- Increased thirst and urination.
Causes of Excess Cortisol
Cushing's syndrome can arise from various factors:
-
Exogenous Corticosteroids: Prolonged use of high-dose corticosteroids (e.g., prednisone) for treating conditions like asthma, arthritis, or autoimmune diseases is the most common cause.
-
Endogenous Cortisol Overproduction:
- Pituitary Tumors: A benign tumor on the pituitary gland (Cushing's disease) can overproduce adrenocorticotropic hormone (ACTH), which stimulates the adrenal glands to produce excess cortisol.
- Adrenal Tumors: Tumors on the adrenal glands themselves can directly produce too much cortisol. These tumors can be benign (adenomas) or cancerous (carcinomas).
- Ectopic ACTH Production: Rarely, tumors in other parts of the body (e.g., lung, pancreas) can produce ACTH, leading to excess cortisol production.
Diagnosis and Treatment
Diagnosing Cushing's syndrome involves:
- Medical History and Physical Exam: Assessing symptoms and risk factors.
- Urine and Saliva Cortisol Tests: Measuring cortisol levels in urine and saliva.
- Blood Tests: Measuring cortisol and ACTH levels in the blood.
- Imaging Tests: CT scans or MRI scans to locate tumors on the pituitary or adrenal glands.
Treatment options depend on the underlying cause:
- Reducing Corticosteroid Use: Gradually tapering off or discontinuing corticosteroid medications under medical supervision.
- Surgery: Removal of pituitary or adrenal tumors.
- Radiation Therapy: Used to shrink pituitary tumors if surgery is not an option.
- Medications: Drugs to inhibit cortisol production or block its effects.
Conclusion
Excess cortisol production, leading to Cushing's syndrome, presents with a variety of signs and symptoms ranging from weight gain and skin changes to musculoskeletal problems and mental health issues. Identifying the underlying cause is crucial for effective treatment and management of the condition.
