syptoms of diabetes

Hello! Can anybody please tell me what the symptoms of diabetes are? Please, I really need to know! Thx!

Diabetes is hard to notice because many symptoms are harmless and often unnoticeable. But, if they are spotted on time, the chances of developing the complications of diabetes are smaller. These are the symptoms of diabetes: frequent urination, excessive thirst, extreme hunger, unusual weight loss, increased fatigue, irritability and blurry vision.
