Conflicting measurements

Hi everyone,

I'm new to this forum. My doctor diagnosed me with prediabetes around 2 months ago. Since then I've been measuring my blood glucose around twice a day, and I'm not on any medication so far.

With my usual meal habit, my fasting BG is around 6.5-7 mmol/L and BG two hours after meal around 8.5-11 mmol/L. I can marginally reach the normal range if I exercise strict control over my diet, but literally I'm hungry all day long if I do that.

Last week I did a HbA1c lab test and result was 4.8% (pretty healthy figure), that isn't quite in line with my BG measurements so I checked with another lab but got the same result. Then I check the accuracy of my BG meter with glucose solutions and it seems accurate.

I'm confused as to which measurements to trust now. My appointment with the doctor is six months later, so I want to see if anyone has similar experience here. Any comments are welcomed.

BTW, I do have ED and is taking sildenafil regularly, not sure if that is affecting the measurements though.

Thanks and regards.

Hi @Tim1972 .. and welcome
You have made a good move coming here. Since joining this forum, the folks here have given me so much info, advice and support that I am now much more confident about the journey ahead. So ask your questions and be assured that you will receive the answers that you need .. It's still early for me but, in my experience, it gets easier .. very quickly ..

Managing and controlling your diabetes through exercise, diet and testing your Blood Glucose seems to be the best way forward. For me, committing to an LCHF (Low Carb High Fat) lifestyle and testing 3-5 times a day seems to be working and you'll find that there is a wealth of info, relevant advice and positive support about LCHF on the forum ..

I have tagged @daisy1 for you and I would suggest that you read up on the Low Carb Program in the information that she will soon be sending you. You might also find the discussion on the Low Carb Diet forum helpful .. and the following websites ...

Hope this helps

@Tim1972
Hello Tim and welcome to the Forum :) Here is the Basic Information we give to new members and I hope you will find it useful. Ask questions and someone will be able to help.


BASIC INFORMATION FOR NEWLY DIAGNOSED DIABETICS

Diabetes is the general term to describe people who have blood that is sweeter than normal. A number of different types of diabetes exist.

A diagnosis of diabetes tends to be a big shock for most of us. It’s far from the end of the world though and on this forum you'll find well over 235,000 people who are demonstrating this.

On the forum we have found that with the number of new people being diagnosed with diabetes each day, sometimes the NHS is not being able to give all the advice it would perhaps like to deliver - particularly with regards to people with type 2 diabetes.

The role of carbohydrate

Carbohydrates are a factor in diabetes because they ultimately break down into sugar (glucose) within our blood. We then need enough insulin to either convert the blood sugar into energy for our body, or to store the blood sugar as body fat.

If the amount of carbohydrate we take in is more than our body’s own (or injected) insulin can cope with, then our blood sugar will rise.

The bad news

Research indicates that raised blood sugar levels over a period of years can lead to organ damage, commonly referred to as diabetic complications.

The good news

People on the forum here have shown that there is plenty of opportunity to keep blood sugar levels from going too high. It’s a daily task but it’s within our reach and it’s well worth the effort.

Controlling your carbs

The info below is primarily aimed at people with type 2 diabetes, however, it may also be of benefit for other types of diabetes as well.

There are two approaches to controlling your carbs:
  • Reduce your carbohydrate intake
  • Choose ‘better’ carbohydrates
Reduce your carbohydrates

A large number of people on this forum have chosen to reduce the amount of carbohydrates they eat as they have found this to be an effective way of improving (lowering) their blood sugar levels.

The carbohydrates which tend to have the most pronounced effect on blood sugar levels tend to be starchy carbohydrates such as rice, pasta, bread, potatoes and similar root vegetables, flour based products (pastry, cakes, biscuits, battered food etc) and certain fruits.

Choosing better carbohydrates

The low glycaemic index diet is often favoured by healthcare professionals but some people with diabetes find that low GI does not help their blood sugar enough and may wish to cut out these foods altogether.

Read more on carbohydrates and diabetes.

Over 145,000 people have taken part in the Low Carb Program - a free 10 week structured education course that is helping people lose weight and reduce medication dependency by explaining the science behind carbs, insulin and GI.

Eating what works for you

Different people respond differently to different types of food. What works for one person may not work so well for another. The best way to see which foods are working for you is to test your blood sugar with a glucose meter.

To be able to see what effect a particular type of food or meal has on your blood sugar is to do a test before the meal and then test after the meal. A test 2 hours after the meal gives a good idea of how your body has reacted to the meal.

The blood sugar ranges recommended by NICE are as follows:

Blood glucose ranges for type 2 diabetes
  • Before meals: 4 to 7 mmol/l
  • 2 hours after meals: under 8.5 mmol/l
Blood glucose ranges for type 1 diabetes (adults)
  • Before meals: 4 to 7 mmol/l
  • 2 hours after meals: under 9 mmol/l
Blood glucose ranges for type 1 diabetes (children)
  • Before meals: 4 to 8 mmol/l
  • 2 hours after meals: under 10 mmol/l
However, those that are able to, may wish to keep blood sugar levels below the NICE after meal targets.

Access to blood glucose test strips

The NICE guidelines suggest that people newly diagnosed with type 2 diabetes should be offered:

  • structured education to every person and/or their carer at and around the time of diagnosis, with annual reinforcement and review
  • self-monitoring of plasma glucose to a person newly diagnosed with type 2 diabetes only as an integral part of his or her self-management education

Therefore both structured education and self-monitoring of blood glucose should be offered to people with type 2 diabetes. Read more on getting access to blood glucose testing supplies.

You may also be interested to read questions to ask at a diabetic clinic.

Thanks both AM1874 and daisy1, will certainly follow your advises. The low carb program is particularly interesting, my BG measurements have shown that cutting carbs can lower my BG, what I haven't try is whether I can take more of other food without raising the BG back. Being hungry all day long is the main reason that I haven't made any serious effort to lower my BG.

Still, I would really appreciate if someone can comment about the conflicting HbA1c and BG measurements.

Hi and welcome to the forum @Tim1972,

There are many knowledgeable members on this forum and I am sure someone who will be along shortly who can comment on your question.

I am no expert, mind you, but I will try to answer your question based on the information I have gained from the many helpful members on this forum.

The Hba1c is based on the assumption that the average life span of red blood cell is three month. However, individuals will differ with respect to how long-lived their red blood cells actually are. So, if your red blood cells are replaced in less than three months, your Hba1c will be lower than predicted by your average blood glucose levels. If your red blood cells live longer than 3 months, your Hba1c will be higher than predicted.

Hi Tim, you should not go hungry when reducing your blood sugars as hunger can raise raise sugars. The LCHF way of eating really works and hope you will give it a try. You don't say what your meals are to cause the high readings, yes they are higher than I would like to be. The Hba1c test will show whats in your blood for around the past three months and not a good indicator of what each meal is doing to your sugars.

Hi Tim
you don't mention what your pre-meal readings are. Whilst fasting blood levels fascinate us, it's because they're a dragon we're trying to tame. Your fasting level isn't an indication of what your blood sugar levels are when not dealing with a meal. In other words it's not your lowest value when trying to work out an average. The Dawn Phenomenon is simply that - a 'higher than it's been during the night' level.
The readings you've given us are the higher levels of your day. You're simply missing the lower readings.
Your HbA1c equates to an average blood level of 5.1.

You're doing fine.

Thanks everyone, it makes more sense now.

As for what I eat, I live in Asia so a good part of what I eat is actually rice and noodles. Before my diagnosis, I was probably taking 3200 kcal a day, I stopped all sugary drinks (I used to drink a bottle of Pocari after my running, now I drink Perrier) since the diagnosis, so my normal meal is like 2800 kcal a day nowadays, among which probably 800 kcal is from carbs.

If I lowered my daily intake to around 2000 kcal a day, with less than 400 kcal of carbs, for more than 2-3 days, then I can reach the normal range marginally. But I'm feeling hungry and losing weight in that case (I'm not fat and don't have much margin to lose weight, BMI=22.5)

Welcome Tim!

definitely on the right track monitoring your BG levels but let me make the soup thicker- what do you know about SPO2 levels and how it relates to diabetes management?

Hi gyf,

Thanks and this is the first time I heard about SPO2 level, I Googled a bit but couldn't find information about how it relates with diabetes management, would be great if you could share some relevant links. My sports watch does measure my VO2 max while I'm running, and I'm doing ok with the values, but I'm not sure if SPO2 and VO2 max are correlated.

By the way, LCHF seems to really work for me. After the great advises here, I did an experiment by eating a full meal of meat and vegetables without carbs for lunch and dinner yesterday, and the BG read 6.1 two hours after meal , where my fasting BG this morning was 4.5 - all without the need to keep being hungry. This LCHF concept is very different from the book I've brought (which emphasize on balanced and controlled intake), but it's much more practical and I'm now optimistic that I can get my BG under control :)

Hey Tim,

SpO2 (wik) stands for peripheral capillary oxygen saturation, an estimate of the amount of oxygen in the blood. More specifically, it is the percentage of oxygenated haemoglobin (haemoglobin containing oxygen) compared to the total amount of haemoglobin in the blood. Fluctuation in SpO2 levels can be an indicator of various chronic/ comorbid conditions while increasing your oxygen capacity can increase respiratory output and performance. and has many health benefits overall..there's tons of information on this and I actually am going to be using cartridges at a Veterans and their families 5k/10k race in a few weeks in Indianapolis.....

Be Well!
