Question regarding readings

I am 50 years old, male. I recently had a fasting blood test. Readings came out to 6.8 (fasting) and 5.9 Hba1c. The Hba1c seems borderline high. The 6.8 is on the higher side as well, and my physician wants me to do a follow-up test (I think it's the one where you have to drink a sugary solution and they take readings for next 2-3 hours to see how your body processes the sugar). I weigh 270 lbs (approximately 19 stone) and am 6 foot tall. I tend not to eat until about 4 p.m. and then will eat from then on until about 12:30 a.m. My blood sugar yesterday morning was 6.6 when I woke up, so I went for a run/walk of about 1.5 miles. It dropped my blood sugar down to 4.1 later in the afternoon where it stayed like that until I ate later in the day (about 6 p.m.) Even after eating my sugar appeared normal for most of the evening. This morning when I woke up, it was 6.8. An hour and a half later it was still the same level. Two hours later and it's dropped to 6.4. I have not moved around a lot this morning. I am a bit concerned over the higher fasting readings when I wake up, and the fact that it does not seem to want to drop, even two hours later after I woke up. Any ideas or suggestions?
 
Surely you don't mean that you eat continuously for 8.5hrs from 4pm? Why do you eat so late?
 
We are not your doctor so we can't diagnose you. I can however tell you that your numbers aren't alarmingly sky high and that you might well get a diagnosis of prediabetes or close to it. Some small tweaks to your diet might get you solidly beneath anything close to diabetes With luck, you might even lose a couple of pounds without really trying.
Despite not having been diagnosed I'll tag @daisy1 who'll post a bunch of very useful information for fledgling diabetics and prediabetics, as you sound curious and willing to tackle this before it's even there!
Good luck!
 
The test you talk about with the sugary drink is called the oral glucose tolerance test. (OGTT)
I would have thought it more likely the doctor is just repeating the HbA1c test. This is normal when someone is borderline and should take place within 2 or 3 weeks of the first test.
 
Surely you don't mean that you eat continuously for 8.5hrs from 4pm? Why do you eat so late?

Thank you for your reply. Correct, I do not eat continuously for 8.5 hours, but I eat numerous times within that window. Why do I eat so late? I do not like to eat much while I am at work, and it's easier to get by without eating to be honest. At times, my stomach goes a bit weird when I eat...so I got used to not eating for most of the day. Thank you again for your reply.
 


Thank you for your reply. You are correct, my numbers are not alarmingly sky high, though, as you mentioned, I have been borderline prediabetic. I agree, it is best to try to avoid it altogether, so I am going to get my act together re. diet/exercise/weight. Thank you again.
 
You're welcome. Please keep us informed on how you get on
 

Thank you for your reply. Yes, not really sure as to why she chose not to repeat the HbA1c versus ordering the OGTT... I did not meet with her. Most of my latest (past 3 years) HbA1c tests have been in the region of 5.9. Need to get my act together. Thank you for your reply.
 
SO it seems you’re already doing intermittent fasting. That also has the benefit of most people are more insulin sensitive in the latter part of the day.

Your higher morning readings may well be down to dawn phenomenon whereby your liver (everyone’s actually) helpfully dumps glucose in the early hours to give you the energy to get up and going. There are numerous threads you can search on here about that. Some swear by a snack before bed, some protein, some fat, a few carb based. Others need a small amount of food on rising to convince the liver you aren’t starving yourself and to stop with the glucose dump. Again some choose protein, fat or carb to do this. This phenomenon is the reason for most people these morning readings are the last to come down.

Most type 2 on here do some form of lower carb eating. Some follow official advice to switch to low GI, slow release brown carbs, many more lower most carbs especially things like bread, rice,pasta, potatoes of all colours, many fruits and obviously sugar. Some go whole hog and go keto and seriously limit all carbs including things like flours and in other fruit and veg etc Have you read about this? It keeps many off the medications or limits the amounts needed. And most importantly helps avoid complications.

Hello mv and welcome to the Forum
Here is the Basic Information we give to new members and I hope you will find it useful.

BASIC INFORMATION FOR NEW MEMBERS

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 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.
