What should blood sugar be 3 hours after eating

Blood sugar levels after eating can vary by age, but a reading below 140 milligrams per deciliter (mg/dL) is generally considered normal.

In contrast, levels over 200 mg/dL or higher may suggest that you have diabetes.

Postprandial glucose is the name for the level of glucose (sugar) in your blood after eating, which tends to spike one hour after eating and return to normal within two hours.

There are different ways to measure this, including a two-hour postprandial glucose (PPG) test, an oral glucose challenge, and a device called a glucometer.

These tests can either help diagnose diabetes or determine if you're taking the right amount of insulin with meals.

Insulin is the hormone that regulates this process and helps move glucose into cells for fuel. Any unused glucose is converted into a form called glycogen and stored in the liver.
