Can you help? is 271 good for blood sugar level?

NOT good: Hi. You should probably see an endocrinologist. You need to have a doctor define a goal blood sugar (BG) range for you and make sure you have the tools necessary to control your diabetes well. Chronically poor BG control increases your risk of things you REALLY don't want to have (blindness, kidney failure, nerve pain, amputations, heart attack, stroke, infections). I suggest you see a specialist.

No: It means you are diabetic and not under good control. You need to see your doctor and get further bloodwork and treatment.
