Hi Team, I just completed my exercises. Prior to that, I ate lunch and took my med. for diabetes. I checked my sugar level and it is 71.

Members responded to a question about whether a blood sugar reading of 71 is normal, with most agreeing it falls on the low side of the healthy range and recommending continued monitoring and a good snack, especially after exercise and medication. Several members shared that while 70 to 130 is considered normal, readings below 70 can trigger alarms on continuous glucose monitors and may signal the need for adjustments in food intake or a conversation with a doctor. A recurring theme was mutual encouragement, with members celebrating each other's A1C achievements and workout milestones while emphasizing the importance of balancing exercise, food, and medication to maintain safe blood sugar levels.

I agree with Gary23 and IVEYROSE. 71 is low. My Freesttyle Libre2 beeps at me if I hit 69 because it's low. Last night it woke me 3 times to get it above 70 and one time it was 53 - very scary, a person could go into a coma if it's too low. It's best if we can average below 150 and that puts us at an A1c of 7. People without diabetes run in the 6s or less. My doc is thrilled when I'm 7. Best wishes to everyone!

Gwen, I'm with the Heart Disease Team. 71 is pretty low. I would say eat a really good snack and if you continue to get readings like that talk with your doctor.

A blood sugar level of 71 after exercise is on the lower end and could potentially lead to lightheadedness, especially for someone with heart disease. It's good that you're having a snack now, as eating something with carbohydrates and protein after exercise can help stabilize your blood sugar levels.

A blood sugar level of 71 after exercise is on the lower end and could potentially lead to lightheadedness, especially for someone with heart disease. It's good that you're having a snack now, as eating something with carbohydrates and protein after exercise can help stabilize your blood sugar levels.

Here are some tips to prevent low blood sugar during and after exercise:
• Eat a light meal or snack before working out
• Stay hydrated before, during, and after exercise
• Monitor how you feel during activity
• Take breaks when needed
• For longer workouts (over an hour), plan to eat within an hour of finishing While you mention feeling fine, which is good, be alert for symptoms like:
• Dizziness
• Nausea
• Anxiety
• Shakiness
• Irregular heartbeat
• Shortness of breath

If you experience any of these symptoms, especially chest pain or severe dizziness, seek immediate medical attention. Always follow your doctor's specific recommendations for exercise and blood sugar management.

Wow Gwen3, you are doing great! I'm very impressed. Congrats to you! I'll keep following your messages, it's encouraging to read.
Today I hit one hour of stationary bike, 6 miles and 300 calories. It brought my blood sugar down to 137 after being higher than 200. Reading your message made me fight for the 6 miles. Thank you! Sue581
