What to do if I have blood glucose level after fasting 113 for a normal weight 32 year old male. Is this pre-diabetic?

Yes: Any fasting blood glucose level within the impaired fasting glucose range, 101-125 mg/dl, qualifies one for pre-diabetic.

My blood glucose level(2 hrs after meal) is 300 immediately after masturbation, i am type 2 and my normal BG is 160-180 after meal. Is this normal?

My blood glucose level(2 hrs after meal) is 300 immediately after masturbation, i am type 2 and my normal BG is 160-180 after meal. Is this normal?

No, not normal: Hi. We don't know what you're using to manage your diabetes, but no, a 300 after a meal is not normal (and masturbating had nothing to do with that). And your "normal" BG range of 160-180 is not normal either. Your A1c forms the basis for assessment of risk of diabetic complications, not your infrequent BG testing. I suggest you talk with your doc, with A1c i mind to fine-tune your regimen. ...Read more

Blood glucose level reaches 200 three hours after eating dinner. Then insulin. How long should I wait to see the lowest possible near normal score?

Blood glucose level reaches 200 three hours after eating dinner. Then insulin. How long should I wait to see the lowest possible near normal score?

Blood sugar: Rapid acting insulin lasts from 4-6 hours and reaches peak effect in 2-3 hours at which time your blood sugar would be at its lowest as a general rule. However if you had taken a long-lasting insulin earlier in the day, it would also be exerting an effect hours later. Your physician who knows your case best is also best qualified to answer your question. ...Read more
