I am a 28 year old healthy female, about 5'8" tall and 140 lbs. My father has diabetes as well as some other family members on his side. I've been having some symptoms that I think relate to diabetes (my toes turn blue, my heels go numb, I get very light headed and weak, I'm tired and hungry most of the time, I have a lot of headaches, and I'm extremely irritable). Are these symptoms of diabetes or could it be something else? How do I ask my doctor about them? I feel like a hypochondriac!
