Which symptom is NOT commonly associated with Addison's disease?

In Addison's disease, which is a form of adrenal insufficiency, the adrenal glands do not produce sufficient amounts of certain hormones, including cortisol and aldosterone. This hormonal imbalance leads to a variety of symptoms that can be quite debilitating. Among these, fatigue is prevalent due to decreased cortisol levels, which are essential for energy metabolism. Abdominal pain is also reported as a symptom, likely related to adrenal crises or gastrointestinal disturbances associated with hormone deficiencies. Amenorrhea, or the absence of menstruation, can occur as hormonal imbalances affect reproductive hormones.

Weight gain, however, is not typically associated with Addison's disease. In fact, patients often experience weight loss and muscle weakness due to the catabolic effects of low cortisol levels. The lack of aldosterone can cause electrolyte imbalances, particularly low sodium and high potassium levels, which also contribute to weight issues unrelated to weight gain. Thus, in the context of Addison's disease, weight gain is not a common symptom and is contrary to the expected clinical presentation.
