A patient with Addison's Disease would most likely experience which of the following?

In Addison's Disease, the adrenal glands produce insufficient amounts of cortisol, which plays a crucial role in regulating metabolism, blood sugar levels, and the body's stress response. One of the primary symptoms of cortisol deficiency is hypoglycemia, or low blood sugar. This occurs because cortisol is necessary for gluconeogenesis, the process by which the liver produces glucose from non-carbohydrate sources. Without adequate cortisol, the body struggles to maintain stable glucose levels, leading to episodes of hypoglycemia, which can cause symptoms such as weakness, confusion, and fatigue.

The other options reflect various conditions that are not typically associated with Addison's Disease. Increased energy is not a symptom due to the general fatigue and weakness that often accompany adrenal insufficiency. High blood pressure may occur in different adrenal disorders but is not characteristic of Addison's, where patients often experience low blood pressure instead. Fluid retention is also unlikely, as adrenal insufficiency typically results in dehydration and electrolyte imbalances, particularly low sodium levels. Thus, hypoglycemia is the most accurate answer regarding the symptoms linked to Addison's Disease.
