Trying to understand high sugar readings

Hi. Sorry for the longer post.

I am not diabetic, or at least I wasn't last week. But have insulin resistance and feel bad energy wise, thou I'm not overweight.

As someone who eats a lot of sugary snacks, I've read a few books on dangers of sugars and decided to change my diet. My sugar before that was OK, a little bit on the higher side but in range.

So I went on a 3 days water fast. Sugar levels during those days were ok, I measured from 4.2 to 5.5. (pricking).

On the fourth day I ate some lettuce, tomato, onion and carrot salad. After that around 18:00 I ate some spinach, sauerkraut, 2 eggs and tempeh (so very little carbs, non sugary). Went to play tennis at 22:00, for 90 minutes. came back and measured my sugar at midnight...is was 6.2.

So I thought weird, but OK. On day 5, I ate around 11:00 3 eggs, sauerkraut, two super thin slices of rye bread /whole, high fiber content/ and goat cheese. Around 16:00 I ate flax seed oil with quark (low fat, high protein yogurt, has 5 grams of natural sugar per 100ml), some walnuts, 100 grams of blueberries and 1 peeled apple. Went to play tennis at 17:30 for 90 minutes, came back home exhausted at 19:40. Sugar - 7.2! Now I was really pissed and confused. Last week, as a test, I are 3 kinder bueons on an empty stomach and sugar went to 7.1. Never have I seen 7.2

Today, I ate lunch around 12:00, 2 tempeh wraps /tempeh, hemp tortilla, lettuce, tomato, sauce with zuchini/ and a salad. No added sugars. At 15:15 I tested my sugar level...7.9! At this point I'm really nervous. Went to apochatery to buy a new pricking test, 45 minutes later my sugar tests at 6.9.

I am really confused, why is my sugar level going crazy like that? Any thoughts or experiences?

The only things that comes to mind (apart from pancreas issues) is that the stress from sport is messing me up. I'm very tired from it. I've been very tired after physical activities for the last few years, but it has been getting worse in the last year. Can that affect sugar levels this much?

Thank you.

  1. Hi there . So glad you were able to post and provide so much detailed information. I do know that according to the American Diabetes Association, exercise can increase your blood sugar levels. That would make sense, given that your levels appear to be elevated directly after exercise. Here's a link to more info: https://diabetes.org/healthy-living/fitness/why-does-exercise-sometimes-raise-blood-sugar.

    Some people also experience fluctuations in blood sugar in the morning. This is called the "dawn phenomenon", which you can read about here: https://type2diabetes.com/clinical/morning-high-blood-sugar.

    Please do let us know if this helps answer some of your questions. We are more than happy to provide more info if we can, or to add any needed clarification.

    1. Hi . I just wanted to check in and see whether you have figured out what is happening with your blood sugar. Have you tried giving yourself a little more time between eating and exercise to test out Cody's theory? It sounds like you have made some super healthy changes and I hope you begin to see the benefits of those changes soon. Best wishes. - Lori (Team Member)
