What is a symptom of Type 2 diabetes?

Excessive urination, or polyuria, is a classic symptom of Type 2 diabetes. This condition occurs when blood sugar levels are persistently high (a state known as hyperglycemia). The kidneys respond by attempting to remove the excess glucose from the bloodstream through urine. As glucose is excreted, it draws more water with it, leading to an increased need to urinate. This symptom is often accompanied by increased thirst as the body seeks to hydrate itself in response to fluid losses.

In contrast, the other options are not commonly associated with Type 2 diabetes. Insomnia can occur for various reasons, but it is not a direct symptom of diabetes. Nosebleeds are generally unrelated to the disease and may result from other health issues or environmental factors. Increased hair growth can be associated with hormonal imbalances or other conditions but is not a recognized symptom of diabetes. Recognizing the key symptoms of diabetes is essential for early diagnosis and management.
