Hello everyone
I was diagnosed prediabetic three weeks ago, Dr didnt say much just try diet and exercise. So ive been walking 30minutes a day etc and have started low carb diet since then. I bought myself a glucose monitor snd my bloods are between 4-6 2hrs after eating. I did a fasting glucose this morning and it came back as 6.2, im a bit gutted to be honest. Any ideas as to why it goes up overnight or am i just expecting too much too soon?
Also does anyone else get the shakes and feel unwell on a low carb diet, i have had days where i have had to eat an oatcake mid morning to stop the shakes etc or do i just need to give my body time to adapt. One final question can anyone recommend any good breakfast options as i find that the hardest meal for low carbs.
Cheers for reading

It's caused by something called the "dawn phenomenon" and happens when our bodies release glucose into the blood stream to get s up in the morning. If you put that term into the search box at the top of the page you will find all the threads that talk about it. (there are loads). Don't worry about it it happens to all of us and is one of the last readings to come down. No need to feel gutted its just natural to get you out of bed!

Have you tried testing your blood sugar levels when you get the shakes? You may just be experiencing "normal" levels for the first time in a while so it would be best to not have the oatcake.
As for breakfast I just have tea or coffee. But bacon and eggs is the perennial favourite filling and tasty or some variation on that theme.
 
Cheers bulkbiker, i guess it just feels like there a lot to learn in a short time and so much conflicting information out there. :)

There is a huge amount to learn and to be honest it never stops.. but for me at least it has lead to a whole new healthy me.
I was lucky in that I found this forum just before diagnosis and stuck to what I learnt from here and Dr Jason Fung (life saver) check out some of his videos on youtube.. He makes easily understandable talks on Type 2 and how best to treat it and rather than being a theoretician is a real life doc who helps patients.

Hello Lettuce leaf and welcome to the Forum :) Here is the Basic Information we give to new members and I hope you will find it useful. Ask as many questions as you like and someone will 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 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.
