Is this prediabetes? Lab results seem confusing...

Recommended Posts

Is this prediabetes? Back in January, I was 30 pounds heavier and I found out my fasting blood sugar was 104 mg/dL. I quickly became alarmed and decided to go on a lifestyle change and lose weight and fend off prediabetes and any health problems. A few months later, by April of this year, I decided to undergo some extensive testing to see how I was doing- I underwent an OGTT, had my fasting glucose again, A1C and fasting insulin levels. My fasting glucose was 91 mg/dL, and my 2 hour sample after 75 grams of glucose was 108 mg/dL. My fasting insulin at that time was 7.2 mIU/mL and under 20 is considered normal . A1C at the time was 5.4 %. Three weeks later, I had another fasting test with insulin measured. This time it was 89 mg/dL and fasting insulin dropped to 4.8 mIU/mL which supposedly is great. After that test, in early May, I went on vacation and indulged in carbs, steaks, pastries, desserts, wine, etc and did not exercise for nearly a month. After my return, I had another OGTT along with fasting insulin test. This time, I did not do so great. My fasting glucose went up to 98 mg/dL and I spiked high at 1 hour after 75 grams of glucose to 187 mg/dL. However, at 2 hours, I was at 125 mg/dL. My fasting insulin this time was higher than ever at 8.2 mIU/mL. So, in just a matter of a few weeks or eating whatever I wanted and being sedentary, my body did not respond as well as you can see on the second test. Lastly, I had my most recent fasting test 2 weeks ago and it was 103 mg/dL. It seems to be if I start indulging too much and stop lifting weights and running, my fasting sugar increases into the prediabetic range though my A1C is normal. I know most of you are not doctors, but do you guys think based on my results I am prediabetic? My doctor did not seem concerned at all. How can anyone use fasting glucose to determine whether someone is prediabetic or not if fasting sugar can vary in just a few weeks depending on diet and activity level? I am confused. By the way, I am 32 years old and male.

Welcome!

 

Perhaps you do not tolerate carbs well.  When I went low carb high fat and exercised, my diabetes went into remission.  You might want to consider getting a cheap meter and strips and do some testing after meals to see how your body reacts to different foods.  Generally, fasting glucose would be the last place you will see a change if you are insulin resistant.

 

Test before you eat and note glucose.  Test 90 minutes, 2 hours, then 3 hours after eating.  Within 2 hours you should be close to where you started.

Thanks for your reply. I tested with a very high carb meal containing between 275-300 grams of carbs. I had Chinese food and ate a generous portion of fried rice, orange chicken, steak, spring rolls, and drank Pepsi. I started off at 89 mg/dL after not eating in several hours. At 1 hour, I went up to between 145 and 150 mg/dL. I didn’t come down exactly at the 2 hour mark, but exactly at 2 hours 10 minutes, I started getting readings around 125 mg/dL. By about 3 hours, I was around 97-100 mg/dL. Normally, I don’t consume 275-300 grams of carbs in 1 meal but this was an experiment and considering being sedentary for several weeks I didn’t think it was terrible but who knows.
