Glucometer reading shows 103 mg/dl after 16 hours of meal. Am I prediabetic?

Hi,

Welcome to icliniq.com.

From the above history, it is noted that you are having a strong family history of diabetes and also you have been noted with prediabetic range blood sugars in the past. Coming to your query, it is ideal to have less than 100 mg/dl blood sugars after 12 to 16 hours post meal. But we cannot label you as prediabetic or diabetic by noting a single value. So I would take it as a prediabetic state, if you have been noted with increased blood sugars in this range on multiple occasions or if three months average blood sugars are between 5.6 to 6.5%. I would like to stress the point that from the data it is found that you are having class 3 obesity, which must be addressed with due importance because it can lead to early diabetes, any lifestyle disease, and sleep apnea too.
