Ask Nurse Lynn: Glucose Monitoring

Question:

Male, 23 years old, unknown subtype

I have PWS. I’m 23, 5’7″. I do not have diabetes, but my grandfather and dad do. I was wondering what my blood sugar should be every day. I just got a glucose monitor so I want to make sure I’m doing good. I do workout every single day in the gym with my trainer and also doing additional cardio. I weigh right now in the 150s. If you can let me know I would appreciate it. Thank you.

Nurse Lynn’s Response:

It’s great to hear how active you are and that you’re paying close attention to your health. Since you do not have diabetes, your blood sugar targets are the same as for most healthy adults. In general, here’s what’s considered normal:

  1. *Before eating (fasting or more than 8 hours after food): about 70–99 mg/dL

  2. *About 2 hours after eating: usually less than 140 mg/dL

  3. *Anytime during the day: typically, between 70–140 mg/dL

Blood sugar can go a little higher or lower for short periods, but if it’s often outside these ranges, it’s a good idea to tell your doctor.

Since you have family members with diabetes, it’s smart to watch your numbers over time and keep up your healthy habits—regular workouts, balanced meals, and enough sleep all help your body keep blood sugar steady.

You’re already doing so much right. Keep tracking your numbers and share them with your doctor at checkups so you can make sure you’re staying on track.
