Hi I am newly diagnosed and have taken a proactive approach to it. I have changed my diet (no sugar, low fruit low carbs) and taken up exercise (rowing). I invested in a blood sugar testing machine and have been taking my sugar every day in the morning and then two hours after meals. The readings have been on average between 4 - 7. I had my results from my 3 months blood tests and was very disappointed to hear that it was 62 well over the needed 49. My question are why? if my sugar has been very controlled is the tests so high still. How long does it take to get blood sugar back into a "healthy range"? Is three months long enough? I really do not want to go on medications. Any advice/guidance or sharing of peoples' experience would be very much appreciated.
 
Hi and welcome @crystal1972
I will tag @daisy1 who will post an information guide for newcomers.
The HbA1c is a measurement taken over the last 3 months. What was your previous HbA1c? How long have you been testing? Sorry for the questions but I'm trying to understand. If you are saying that for the last 3 months your average readings are all between 4 and 7, even 2 hours after a meal then I would be surprised to see your result and you would need to take all your results to show your doctor and ask him.
 
hi thank you for the response and i don't mind all of the questions. God knows I have loads of them. lol! I don't have a previous HbA1c reading this is the 1st. I have been testing since 11th March 2016. I was surprised too. Well disappointed to be honest. I have an appointment with the surgery next week and I plan to take all of readings with me and really try to get some type of clarity. I have been following a LCHF diet and have lost weight. How much I am not sure but my clothes are fitting much looser. I guess i am just really trying to gauge how long one should wait to see an improvement in that HbA1c number.
 
HbA1c is an average of the whole of the last 3 months, which include January and February. Your next test should show a lot of improvement.
 
OF COURSE!!!! Now that makes sense!!! Thank you so much for that!!

3 months backwards from the day of the blood test. It is weighted towards the last month.
Well done on your progress so far. I found a meter really helpful in finding what I could eat and what I needed to avoid by testing before a meal and 2 hours after a meal. It took me 3 months to get down to 50, hopefully you will be able to do better.
Do come back with questions and people will try and help.
 
Yes, the HbA1c includes blood glucose back 2 to 3 months before the test, although it is weighted towards the last few weeks.

I would also say that your meter readings may be giving you a false sense of security. Testing at 2 hours after a meal will not give you an estimated HbA1c. Depending on the combination of foods eaten at a meal, your peaks will be anywhere from half an hour onwards. You could well be missing your peaks. The aim is to be well on the way back down by 2 hours rather than peaking at 2 hours. If you really want to check this, try testing at an hour after first bite and half an hour thereafter until you return to where you started. I'm not at all suggesting you do this with every meal, just try it out and see what happens. I know from my own testing that I tend to peak round about 90 minutes after evening meal (earlier at other meals) and am well back down at 2 hours..

Hello and welcome to the forum :) Here is the basic information we give to new members which contains a lot of information on carbs and a link to the Low Carb Program. Ask as many questions as you need to 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 over 150,000 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

Another option is to replace ‘white carbohydrates’ (such as white bread, white rice, white flour etc) with whole grain varieties. The idea behind having whole grain varieties is that the carbohydrates get broken down slower than the white varieties –and these are said to have a lower glycaemic index.
http://www.diabetes.co.uk/food/diabetes-and-whole-grains.html

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.

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 bloodglucose testing supplies.
