Blood sugar 10.4 then fasted for 12 hours tested again & it was 9.1 Does this mean I may be diabetic? I understand you cant diagnose but was hoping for some advice as to what the figures could mean in terms of diagnosis? I also have high lipids? Have pain & some numbness in my 1 foot around ankle! I'm constantly & extremely tired, sweat terribly & generally feel very lethargic & no energy whatsoever Docs appointment next week!
