What can cause a dip in the postprandial blood sugar levels?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

My fasting sugar result was 87 mg/dL, and postprandial was 61 mg/dL. Why is it so? I had a usual breakfast, including carbs with some amount of protein. What could be the possible reason? Also, I struggle a lot with weight loss.

Hello,

Welcome to icliniq.com.

A slight variation in fasting and PP (postprandial) glucose levels can occur. It is not unusual. Please tell me with the value 61 with food, did you have any symptoms of hypoglycemia? This looks like reactive hypoglycemia, which tends to happen in persons with excess weight plus when one takes too much of sugary foods or drinks like aerated drinks, juices, etc. With a BMI (body mass index) of 33.57 you are already close to grade 2 obesity. Your ideal body weight should be 143 pounds, which means there is an excess of almost 66 pounds. This is one of the reasons for reactive hypoglycemia. It is also an indicator of future development of diabetes. So avoid sugary foods, juices, and sweets. Take a healthy diet, plus make serious efforts to reduce weight. Also please check your thyroid functions.
