My seven year old son has been complaining about being thirsty all the time, and with that, he is also having to use the restroom almost constantly, including during the night. He has also had several days off school because he says he is really tired and dizzy all the time. Finally, my son has lost some weight. These are all symptoms of diabetes. What do you think I should do now? Could my son have diabetes at this age? And where do I need to get him tested?
