What is a common symptom of Addison's disease?

Fatigue is a common symptom of Addison's disease, which results from an insufficiency of adrenal hormones, particularly cortisol. This hormone plays a crucial role in the body’s response to stress, metabolism regulation, and immune system function. When cortisol levels are low, individuals often experience persistent fatigue due to the body's diminished ability to respond to stress and its decreased metabolic efficiency.

In addition to fatigue, other symptoms of Addison's disease may include weight loss, decreased appetite, and even skin changes like hyperpigmentation. Understanding this connection between cortisol levels and fatigue can help in recognizing and treating Addison's disease effectively.
