What are common symptoms of Addison's disease?

Addison's disease, also known as primary adrenal insufficiency, occurs when the adrenal glands do not produce sufficient amounts of certain hormones, particularly cortisol and aldosterone. The symptoms associated with Addison's disease are distinctive and stem from this hormonal deficiency.

The correct answer includes fatigue, weight loss, low blood pressure, and salt cravings as common symptoms. Fatigue and weight loss are primary indicators of the condition, as the lack of cortisol affects metabolism and energy levels. Low blood pressure can result from insufficient aldosterone, which helps regulate salt and water balance, thus impacting blood volume and pressure. Salt cravings arise because of the body’s need for sodium, which is often excreted more than normal due to low aldosterone levels.

Understanding these symptoms is crucial for early identification and management of Addison's disease, as untreated conditions can lead to more severe complications, including an adrenal crisis, characterized by severe hypotension and shock. Recognizing the combination of fatigue, weight loss, low blood pressure, and cravings for salt underscores the need for proper medical evaluation when these symptoms occur.
