Blood sugars down AFTER eating?

Hi guys,

Not been 100% over the last few days.

I usually wake up to a 5.1 FBG, but in the recent last 2-3 days it’s been 5.3.

This morning I tested 3 separate times - all before breakfast.

9 am - 5.3
9.15 am - 5.5
10 am - 5.9

So I decided it was a “bad day”, and went on to have a breakfast of low carb bread, cheese, a full avocado and a cup of decaf.

I tested twice again 45 / 60 minutes later after meal and my BS is 5.6 / 5.8.

These readings are confusing to me. If anyone can help me understand what’s going on with my BS?

Thanks.
 
Hi Danski,

What type of diabetes do you have?

You might want to establish a trend, establish the effect of each type of food, and quantiles by trying to test in pairs.

First Pair
1) Fasting- As soon as you wake-up
2) Two hours after your first meal

Second Pair

1) Before second meal
2) Two hours after the second meal

Third Pair

1) Before dinner/3rd meal
2) Two hours after dinner and/ or before bed (Compare this number with your fasting number for the following morning

Notes:
1)Record every food (Type, portion, total calories)
2) Drink a lot of water through out
3) If not full increase vegetables and/or raw cucumbers
- Cucumbers bulky and filling, no calories but full of nourishing water and vitamin)
4)Try to do this consistently for a week or two, see if you can have some insights out the data and share the data with your doctor.
5) Armed with this kind of information the doctor will be able to advise and recommend a scientific intervention.
6) Target ranges:
  • Pre-diabetes target ranges: Fasting BG <100 BG <140 all other times A1C goal <5.7%
  • Type 2: Fasting/Before < meals 130 and < 180 any other time

Wish mine were that low. Wouldn't be having carbs. They look fine to me.

The figures are fine in themselves. Monitors aren't precise - I think there is a 15% allowed tolerance in the readings they give. The rises you report are marginal anyway.

Don't forget that your BGs will vary because of factors other than food - mine jump around because of ambient temperature, illness (even very mild), stress, activity, etc. That's before you factor in the meter and the strips. In the mornings my liver will sometimes happily go on dumping glucose (with associated BG rise) until I eat something. I think somewhere on here there's a list of about 40 factors that people have reported as "affecting blood glucose".

Why would you think these readings make it a bad day? Lots of people would love to see levels this good.
As robbity said the meters are not that accurate, each time you take a reading your actual level could be higher or lower by 15%.
All I can see from these 3 results is that at 9 am your actual level was in the low 5's, possibly high 4's
And 1hr later it was somewhere in the mid 5's to low 6 range, all perfectly acceptable reading's.
We can probably say with some confidence that between 9am and 10am your levels have risen slightly.
Our levels are not static throughout the day and will be constantly moving up or down depending on many factors. It's not just food that affects your blood sugar, quality of sleep, hot/cold weather, activities like showering, gardening, housework, just about anything can cause it to change.

OK so if we take into account the 15% accuracy, this shows that an hour after a low carb breakfast your levels were in the same range as they were at 10am.
Your breakfast was perfect, well done, you're really getting the hang of this low carb malarkey.

Hi, I agree mostly with your idea of establishing a way to track your blood glucose levels.
However, a fasting level is done pre breakfast, not on waking. Because of dawn phenomenon. This is your liver gives you a boost of glucose to get you up in the morning.
Testing before food at least half an hour after waking will give you a more correct reading of your fasting levels.

Also, if you can increase your natural full fats, instead of low fats, which are full of sugar. And beware of starchy carbs. A low carb diet is recommended on here whether vegan or not.
 
A lot of non diabetics would struggle to maintain readings like yours. Food science is never exact. we cook in a saucepan, not a testube.
