Which of the following symptoms indicates hyperglycemia in a person with Cushing's syndrome?

In the context of Cushing's syndrome, hyperglycemia is a common symptom due to elevated levels of cortisol, a hormone that increases blood sugar levels. Increased urination, also known as polyuria, occurs as a result of the kidneys attempting to excrete excess glucose from the bloodstream. Therefore, when blood sugar levels are high, the kidneys filter out more glucose, leading to increased urination.

The presence of multiple contributing factors in Cushing's syndrome, such as insulin resistance and alterations in carbohydrate metabolism, reinforces this relationship between high cortisol levels, elevated blood sugar, and increased urination. This helps to differentiate it from symptoms that would suggest low blood sugar, low blood pressure, or fatigue, which are not indicative of hyperglycemia associated with Cushing's syndrome. Hence, increased urination serves as a clear indicator of hyperglycemia in this specific condition.
