Is it possible to have a high insulin but normal blood sugar levels?

How does one lower blood sugar levels and can insulin go bad?

• my friend is diabetic and his blood sugar level has been between 430 and 515 for 3 days, he says he does not feel that bad but he is scared. he is wondering if maybe his insulin is not working because he left it in a warm car. does any one have any answers? he is drinking water and not eating any sugars and injecting insulin as directed.

• Answer:

  Glucose levels this high are very serious. Your friend needs to see his physician tomorrow. Yes insulin can 'go bad'. It generally retains potency at room temperature for up to one month but in a 'hot' car it may be destroyed. Again - I cannot emphasize enough - this is a medical emergency and your friend must seek prompt attention. No delay is acceptable. People become comatose at different glucose levels so I am not able to say that this is imminent but if I was his physician I would see him immediately. I hope that his physician feels the same way and I hope that your friend understands that this may become a life-threatening situation. Please tell him to seek medical attention immediately.
