Short Summary

Main recommendation: Target blood sugar two hours after eating based on your age, how long you have had diabetes, your diabetes type, and your medications, rather than one fixed number; Dr. Ergin suggests under 160 mg/dL for newly diagnosed or relatively young type 2 patients, under 180 for longer-standing patients with complications concerns or difficulty with control, and under 200 for patients with advanced kidney disease or on insulin or sulfonylureas. Occasional readings of 180 to 200 are described as not a big deal if they are not happening all the time.

Key Points

  • Blood sugar goals vary by age, diabetes duration, diabetes type, medications, and existing complications; the speaker states these factors determine a possible goal.
  • For newly diagnosed patients, the speaker says a two-hour reading under 160 mg/dL is the target, while fasting goals around 120 (and possibly 90 for some newly diagnosed people) are mentioned.
  • For people with 15+ years of diabetes and no kidney disease, eye disease, or neuropathy, the speaker suggests relaxing to around 180, since strict control becomes harder.
  • The speaker says the damage to the endothelial lining is generally associated with readings at or above 180 mg/dL, while noting genetic background varies and some people are more sensitive.
  • Chronic kidney disease (stages 3 to 5) and use of insulin mixes or sulfonylureas raise the risk of late low blood sugar, so goals may be relaxed to around 200 to avoid lows.
  • Senior patients (for example, diagnosed around 75 and now 80 or older) are said to be less likely to develop complications if readings stay under 200 after meals.

Details Worth Noting

  • Concrete instructions:

    • Check blood sugar one to two hours after a meal; the speaker says either timing is fine and advises against overly strict rules.
    • If a continuous glucose monitor (CGM) is used, options named are Dexcom G6, Dexcom G7, FreeStyle Libre 2 (14-day), and FreeStyle Libre 3. The Libre 3 does not require scanning and needs a smartphone, not a separate meter; the speaker says it is more economical out of pocket.
    • For low blood sugar symptoms (sweating, shakiness, racing heart, especially late at night): check blood sugar immediately, eat 15 to 20 grams of carbohydrate (not more), then recheck with a finger stick in 15 to 20 minutes, since CGMs lag about 20 minutes.

  • The speaker says pregnant women with gestational or pregestational type 2 diabetes should aim under 120 mg/dL two hours after meals, achievable on a low-carb diet if not on medications that drop blood sugar too far.

  • The speaker says normal people's blood sugar can reach 140 to 150 after meals without causing complications if it returns in an hour or two.

  • The speaker mentions GLP-1 agents and SGLT2 inhibitors as options that can keep CGM readings steady when not using insulin or sulfonylureas.

  • This is the speaker's general guidance, not professional medical advice for any individual.

Bottom Line

Your two-hour post-meal blood sugar target depends on your personal profile, so the speaker's guidance is to set a goal with your clinician that fits your age, duration, complications, and medications, while watching for late lows if you use insulin or sulfonylureas.
