Hello, I m a 20 year old female med student and in class we did a glucose tolerance test and me glycemia was constantly rising, in reached a peak of 305 mg/dl al 77 min, and al 90 minutes it was 280 (we did not performed further readings), my BMI is 21, and I never drink/smoke, I eat very healthy, except for the sedentary medschool induced life, I consider myself a healthy person. Theres no history of diabetes in my family... the only symptom that I have is that my vision goes a little b it blurry since 3 years if I dont put effort on focusing. .. should I be worried? Thanks in advance
