I have a 12 hour fasting blood sugar of 104mg/dl. I'm very worried. Is it certain that I will develop diabetes? Pls help.

Need more tests. 104 fasting is in the prediabetes range but can't make the diagnosis on one number. See your doctor for another fasting sugar draw or a test called hemoglobin a1c. If it's between 5.7-6.4 and fasting sugar 100-125, then you have prediabetes. This is the most important time to get an exercise and diet regimen going. At this stage, it's reversible.
