What are the signs of diabetes?

Just curious. What are the signs of getting diabetes?

frequent urination, excessive thirst, unusual fatigue, unexplained weight loss, numbness or tingling of the extremities, blurred vision, dry or itchy skin, recurrent infections, and cuts and bruises that take a long time to heal.

Drinking lots of water(well, feeling like you need to), losing weight, feeling weak and exhausted, pins and needles. There are probably more.
If you're worried you have these symptoms, you need to see a doctor so they can do some tests.
