Question from Michigan, USA:

I am 20 years old and ever since I was young, I have always loved candy and sugar. In the last few years, tt seems that if I don’t eat food at specific times of the day, I feel really tired and faint to the point where I feel like I am going to pass out. Also, I almost always pass out when I am in a physically stressful situation like at the dentist or getting blood drawn. Could I have possibly “programmed” my body to need a certain amount or sugar and or carbohydrates? I have also been urinating a lot lately and been really tired even though I am usually not tired even after the active lifestyle that I lead. Am I at risk for diabetes?
