Adrenal glands are small, triangular-shaped endocrine glands located on top of each kidney. They produce and release hormones, including cortisol, adrenaline, and aldosterone, which regulate metabolism, stress response, blood pressure, and the body’s response to various stressors. The adrenal glands are essential endocrine system components, coordinating with other glands to maintain proper physiological balance and support various bodily functions. However, like any complex system, the adrenal glands can be susceptible to various disorders that can disrupt their normal function.
From Addison’s disease’s debilitating effects to Cushing’s syndrome’s hormone excesses, understanding these common disorders is crucial for early detection, diagnosis, and effective management.
In exploring common adrenal gland disorders, we will delve into their effects on the body and the available treatment options, providing valuable insights into these intricate aspects of human health.
What Are Adrenal Glands Disorders?
The adrenal glands are crucial organs that regulate the hormonal system of the human body. Sometimes, due to certain genetic causes or infections, the adrenal gland does not function properly. As a result, it leads to insufficient hormone production and adrenal gland disorders.
Common Disorders of the Adrenal Glands
Here are some common disorders of the adrenal glands, their effects, and treatment options:
Adrenal Insufficiency (or Addison’s disease)
Adrenal insufficiency, also known as Addison’s disease, occurs when the adrenal glands don’t produce enough cortisol and sometimes insufficient aldosterone. The primary causes can be autoimmune destruction of the adrenal glands, infections, or certain medications.
- Symptoms. Common symptoms include extreme tiredness, sudden weight loss, muscle weakness, low blood pressure, and skin darkening.
- Treatment: Treatment involves hormone replacement therapy to replace the deficient hormones, usually with oral corticosteroids (e.g., hydrocortisone) and mineralocorticoids (e.g., fludrocortisone).
Cushing’s syndrome is caused by excessive cortisol levels in the body, either due to overactive adrenal glands or prolonged use of corticosteroid medications.
- Symptoms. Symptoms include weight gain, especially around the face and abdomen (“moon face” and “buffalo hump”), thinning skin, muscle weakness, and mood changes.
- Treatment: The treatment approach depends on the underlying cause. If the disorder is caused by corticosteroid medication, the dosage may be reduced or replaced with alternatives.
In cases where a tumour in the adrenal or pituitary gland causes the condition, surgery or radiation therapy might be necessary.
Adrenal tumours can be either benign or malignant. Adenomas are non-cancerous tumours, while adrenal carcinomas are rare but aggressive cancerous growths. These tumours can produce excessive hormones, causing various imbalances and health issues.
Symptoms. Symptoms of adrenal tumours include high blood pressure, weight gain, muscle weakness, excessive hair growth, and changes in mood and behaviour.
Treatment: The treatment approach for adrenal tumours includes a combination of radiation therapy, chemotherapy, and surgery. Apart from this, palliative care is also necessary.
Congenital Adrenal Hyperplasia (CAH)
CAH is a group of genetic disorders that affect the adrenal glands’ ability to produce cortisol and aldosterone adequately. CAH can lead to hormone imbalances and excess production of androgens (male sex hormones), leading to ambiguous genitalia in females and early puberty in both sexes.
- Symptoms. Symptoms of Congenital Adrenal Hyperplasia (CAH) include ambiguous genitalia in females, early puberty, growth and development issues, and salt-wasting crisis.
- Treatment: Treatment aims to replace deficient hormones and manage excessive androgen production. Lifelong hormone replacement therapy is necessary to regulate hormone levels and manage symptoms. Close monitoring and early intervention are essential to prevent complications.
An adrenal crisis is a life-threatening condition that occurs when there is a severe cortisol deficiency, often triggered by stress or acute illness in individuals with adrenal insufficiency.
- Symptoms. Symptoms include extreme fatigue, confusion, dehydration, and a drop in blood pressure.
- Treatment: An adrenal crisis requires immediate medical attention. Treatment involves intravenous administration of corticosteroids and fluids to stabilise the individual and correct the hormone deficiency.

The adrenal glands and their hormone production are vital for maintaining various bodily functions. Disorders of the adrenal glands can cause significant health problems. Many of these conditions can be effectively managed with early diagnosis and appropriate treatment, allowing individuals to lead healthy lives.
Q. What are the adrenal glands, and what do they do?
A. The adrenal glands are two small glands located on top of each kidney. They produce essential hormones such as cortisol, aldosterone, and adrenaline, which play crucial roles in regulating metabolism, the immune response, blood pressure, and the body’s response to stress.
Q. What are the disorders of the adrenal glands?
A. The disorders associated with the adrenal glands include,
- Addison’s Disease
- Congenital Adrenal Hyperplasia (CAH)
- Cushing’s Syndrome
- Aldosterone-producing adenoma
- Adrenal gland cancer
- Hereditary paraganglioma-pheochromocytoma
Q. How are adrenal gland disorders diagnosed?
A. Adrenal gland disorders are typically diagnosed through a combination of medical history, physical examination, and various tests, including blood tests to measure hormone levels, imaging studies (CT or MRI) to visualise the adrenal glands, and sometimes specialised stimulation tests to assess their function. A consultation with an endocrinologist is essential for accurate diagnosis and treatment.
Q. Are adrenal gland disorders treatable?
A. Yes, many adrenal gland disorders are treatable. Treatment options depend on the specific disorder and may involve hormone replacement therapy, surgical removal of tumours, or medications to control hormone levels. With proper management, individuals with adrenal gland disorders can lead healthy lives.
