What is adrenal insufficiency called Adrenal insufficiency is a condition where the adrenal glands fail to produce adequate amounts of essential hormones, primarily cortisol and, in some cases, aldosterone. These hormones play vital roles in regulating metabolism, immune response, blood pressure, and stress management. When the adrenal glands do not function properly, it can lead to significant health issues that require prompt diagnosis and treatment.
What is adrenal insufficiency called The medical term most commonly used to describe this condition is “adrenal insufficiency.” It is sometimes referred to by more specific names depending on its cause and severity. For instance, when the problem originates from the adrenal glands themselves, it is called primary adrenal insufficiency or Addison’s disease. Addison’s disease, named after the British physician Thomas Addison who first described it in the 19th century, results when the adrenal glands are damaged or destroyed, often due to autoimmune processes, infections, or other rare conditions. The destruction impairs hormone production, leading to symptoms such as fatigue, muscle weakness, weight loss, low blood pressure, and hyperpigmentation of the skin.
Secondary adrenal insufficiency, on the other hand, occurs when the problem lies outside the adrenal glands, most commonly involving the pituitary gland. The pituitary produces adrenocorticotropic hormone (ACTH), which stimulates the adrenal glands to produce cortisol. If the pituitary fails to produce enough ACTH, cortisol levels drop even if the adrenal glands are healthy. This form may be caused by tumors, pituitary surgery, or long-term use of corticosteroid medications that suppress natural hormone production.
What is adrenal insufficiency called Another related term is tertiary adrenal insufficiency, which is less common. It results from hypothalamic dysfunction where the hypothalamus fails to produce corticotropin-releasing hormone (CRH), leading to decreased stimulation of the pituitary and subsequently the adrenal glands.
Understanding the differences between these types is important because they influence treatment approaches. Typically, adrenal insufficiency is managed with hormone replacement therapy, primarily corticosteroids like hydrocortisone, to compensate for the deficient hormones. Treatment must be carefully tailored to the type and severity of the condition, and patients are often educated on how to adjust medication during stress or illness to prevent an adrenal crisis—a life-threatening situation where cortisol levels become dangerously low.

Diagnosing adrenal insufficiency involves blood tests measuring cortisol, ACTH, and sometimes other hormones, along with stimulation tests to assess how the adrenal glands respond to stimulation. Imaging studies such as CT scans or MRI may be used to identify underlying causes like tumors or gland damage. What is adrenal insufficiency called
In summary, adrenal insufficiency is a broad term encompassing various conditions where the adrenal glands do not produce enough hormones. The most specific and commonly used names are Addison’s disease for primary adrenal failure and secondary adrenal insufficiency for cases caused by pituitary problems. Recognizing these distinctions is key to effective management and improving patient outcomes. What is adrenal insufficiency called
