Which of the following is a typical symptom of diabetes mellitus?

Frequent urination, also known as polyuria, is a typical symptom of diabetes mellitus due to the body's attempt to eliminate excess glucose through urine. When blood glucose levels become elevated, the kidneys work to filter out this excess glucose, resulting in increased urine production. This can lead to a cycle where the affected individual feels dehydrated and drinks more fluids, further contributing to the need to urinate frequently. This symptom is particularly common in people with uncontrolled diabetes, where high blood sugar levels significantly impact kidney function and fluid balance.
