Blood sugar 128 mg/dl (7.1mmol/l) after eating - is that good or bad?
We help you interpret your blood sugar values. You have tested your blood sugar after eating and the result was 128 mg/dl. Let's have a look at the blood sugar gauge:
Normal blood sugar
Your blood sugar level (up to 2 hours) after eating should always be below 140mg/dl but not fall below 80mg/dl.
• Age 50 and under: Less than 140 mg/dl
• Age 50 – 60: Less than 150 mg/dl
• Over age 60: Less than 160 mg/dl
A doctor may recommend different postprandial blood sugar levels based on an individual’s particular circumstances and health history.
Several factors may cause a person’s postprandial blood sugar to remain elevated.
• Smoking after the meal: Studies show that smoking raises blood sugar levels in people with diabetes.
• Extreme stress: Stress produces the body’s fight-or-flight response triggering the release of stress hormones such as cortisol. These hormones cause the body to release the glucose it has previously stored for energy.
• Eating or drinking after the meal and before testing the blood sugar: Continuing to eat will keep blood sugars closer to their immediate post-meal levels.
Studies show that 15 to 20 minutes of moderate exercise, such as walking, shortly after a meal may improve glucose metabolism and reduce postprandial glucose levels.
