2. Increased Urination
Any change in the frequency and urgency of urination could lead a doctor to suspect diabetes. More frequent urination is often a wake-up call that you have an underlying health condition, especially if that wake up call interrupts your sleep multiple times a night.
This is due to the fact that individuals with type 2 diabetes have overactive kidneys that are working to eliminate excess glucose in the blood, and the fastest way to eliminate anything from the body is through urination. Keep in mind that this increased urine output may not only keep you up at night, it can also cause dehydration, so be sure to hydrate.
