Have you ever heard of “postprandial hyperglycemia”?

In a healthy person, when the blood sugar level rises after eating, this will trigger the release of more insulin, which is a hormone that helps to regulate our blood sugar. The blood sugar level will then return to normal in about 2 to 3 hours. However, in people who have diabetes or who are in the early stage of diabetes, they are unable to secrete sufficient insulin, and thus their blood sugar level will remain elevated for a longer time. This condition is known as “postprandial hyperglycemia”, and it is one of the main indicators in people with diabetes or prediabetes.

Effective countermeasures for postprandial hyperglycemia

A study conducted in 2013 by George Washington University compared the effectiveness of walking 45 minutes once a day with walking 15 minutes after each meal (three times daily) on glycemic control.1 At the end of the study, it was concluded that both walking methods were equally effective in lowering blood sugar level after meals.

So, if you think that taking a 45 minutes’ walk is too troublesome, it is also okay to just take a 15 minutes’ walk after each meal. After a while, it will develop into a habit and it will certainly make you healthier.
