But after a meal, when blood-glucose spikes, much more insulin is released. The body can now regulate the extra sugar properly, preventing abnormally high levels of glucose—known as hyperglycemia.

To prevent glucose levels from staying too high or for longer durations than the body can absorb after eating, it's important to get enough exercise and to be mindful of what you eat.

Among all participants, those with blood glucose levels below 162 mg/dL one hour post-glucose load (shown in blue) had a higher survival rate. Credit: PNAS Nexus (2025). DOI: 10.1093/pnasnexus/pgaf179 ...

Everyone’s glucose levels rise when you eat, as food is broken down into simple sugars to act as fuel to keep our bodies up and running. When we eat, our bodies have to work to process the ...

When one is having blood sugar levels tested to check for type 2 diabetes or prediabetes at a doctor's office, for instance, a trained physician will oversee and interpret one of the following ...

How closely should you be tracking your blood-sugar levels? People with diabetes have long used devices to monitor their glucose fluctuations. In the past few years, a broader group of people have ...

To prevent glucose levels from staying too high or for longer durations than the body can absorb after eating, it's important to get enough exercise and to be mindful of what you eat.

Using this threshold, Imai and his colleagues conducted a survival analysis, comparing those with post-glucose load blood glucose levels below and above 170 mg/dL. After 20 years, nearly 80% of ...
