Adrenal Insufficiency (Addison’s Disease)

Addison's disease is a rare but serious endocrine disorder in which the adrenal glands fail to produce adequate amounts of essential hormones, particularly cortisol and aldosterone. These hormones are crucial for maintaining blood pressure, metabolism, immune function, and the body’s response to stress. The condition often develops gradually and may go unnoticed until symptoms become more severe.

Common causes include autoimmune destruction of the adrenal cortex, infections, genetic conditions, or damage due to medications or surgery. Symptoms typically include chronic fatigue, muscle weakness, weight loss, low blood pressure, salt cravings, and darkening of the skin (hyperpigmentation). Patients may also experience nausea, abdominal pain, and dizziness, especially when standing.

If left untreated, Addison’s disease can lead to an adrenal crisis, a life-threatening condition characterized by severe dehydration, low blood pressure, and shock. Prompt medical attention is essential in such cases.

Diagnosis involves blood tests to measure hormone levels and assess adrenal function, along with imaging studies if needed. Treatment primarily includes lifelong hormone replacement therapy to restore normal hormone levels. With proper management and regular monitoring, individuals can lead healthy and active lives.
