Addison's disease

Addison's disease, also known as primary adrenal insufficiency, is a condition where the adrenal glands do not produce enough hormones, particularly cortisol and aldosterone. Symptoms of Addison's disease can include extreme fatigue, weight loss, low blood pressure, and darkening of the skin, as well as cravings for salt. The causes of this condition often involve autoimmune issues, where the body's immune system mistakenly attacks the adrenal glands, but it can also result from infections, such as tuberculosis, or other medical conditions that affect the adrenal glands. Treatment typically involves hormone replacement therapy to restore the levels of cortisol and aldosterone in the body. This is usually done through daily oral medications, and patients may need to adjust their dosage during times of stress, illness, or injury. With appropriate treatment, individuals with Addison's disease can lead healthy, active lives.
