What happens with adrenal insufficiency
What happens with adrenal insufficiency Adrenal insufficiency, also known as Addison’s disease or hypocortisolism, is a condition where the adrenal glands fail to produce adequate amounts of hormones, primarily cortisol and sometimes aldosterone. These hormones are vital for several bodily functions, including managing stress, maintaining blood pressure, regulating metabolism, and balancing electrolytes. When their production is compromised, a cascade of health issues can arise, affecting multiple systems in the body.
What happens with adrenal insufficiency The adrenal glands are small, triangular organs located on top of each kidney. They function as part of the endocrine system, secreting hormones directly into the bloodstream. Cortisol, often called the “stress hormone,” helps the body respond to stress, control blood sugar levels, regulate blood pressure, and reduce inflammation. Aldosterone plays a crucial role in sodium and potassium balance and helps control blood pressure by regulating fluid levels.
Adrenal insufficiency can be caused by various factors. Primary adrenal insufficiency, or Addison’s disease, results from damage or destruction of the adrenal glands themselves, often due to autoimmune reactions, infections like tuberculosis, or adrenal hemorrhage. Secondary adrenal insufficiency occurs when the pituitary gland, which signals the adrenal glands to produce hormones, fails to produce enough adrenocorticotropic hormone (ACTH). This can be due to pituitary tumors, surgery, or long-term use of corticosteroid medications, which suppress natural hormone production.
What happens with adrenal insufficiency Symptoms of adrenal insufficiency usually develop gradually, though they can sometimes appear suddenly. Common signs include chronic fatigue, muscle weakness, loss of appetite, weight loss, abdominal pain, and low blood pressure. Because cortisol influences blood sugar levels, individuals may experience hypoglycemia or dizziness. Skin changes, such as hyperpigmentation, are typical in Addison’s disease, especially in areas exposed to friction. In severe cases, an adrenal crisis can occur—a life-threatening situation characterized by severe weakness, dehydration, low blood pressure, confusion, and even loss of consciousness. This crisis often results from stress, infection, or abrupt cessation of steroids, and requires immediate medical treatment.
Diagnosis involves a combination of blood tests to measure cortisol and ACTH levels, electrolyte panels, and imaging studies of the adrenal glands or pituitary. The ACTH stimulation test is commonly used to confirm adrenal insufficiency. Treatment primarily involves hormone replacement therapy to compensate for the deficient hormones. Glucocorticoids like hydrocortisone are prescribed to replace cortisol, while mineralocorticoids such as fludrocortisone help maintain electrolyte balance and blood pressure in primary adrenal insufficiency.

Managing adrenal insufficiency requires lifelong commitment to medication adherence, regular monitoring, and adjusting doses during periods of stress or illness. Patients are advised to carry medical alert identification and have an emergency plan in case of an adrenal crisis. Education about recognizing early symptoms of crisis and understanding when to seek urgent medical attention can be lifesaving. What happens with adrenal insufficiency
Overall, while adrenal insufficiency can be a chronic and challenging condition, with proper treatment and management, individuals can lead active, healthy lives. Advances in understanding and therapy continue to improve outcomes, making early diagnosis and consistent care essential. What happens with adrenal insufficiency
