Hi, I've been reading the site for the past 4 hours now and simply cannot find anything that says how long after a meal I should be testing my levels but there's a lot I haven't read still. I have for the past 4 months been doing it an hour and a half after my meals but I have read elsewhere on the internet that it should be 2 hours. I have read the blood glucose testing section and FAQ and testing times and when to test but none of them appear to say how long after a meal. Help!
 
Usually we say before the first mouthful and then 2 hours afterwards to see the impact of the food on your blood sugar levels.
You want to see a rise of less than 2mmol if it's more then something in the meal didn't agree with your Type 2.
 
Thanks. I don't know why I've been doing it 90 mins after eating but if it's 2 hours from just before starting the meal I will probably only be about 10 minutes short of the 2 hour mark. Would that make much of a difference do you think? And, does it say anywhere on this site about it being 2 hours because I just couldn't find it at all. I can't think why I've been doing it at 90 mins instead of 2 hours
 
If you have been testing before and 90 minutes after starting a meal, that is OK. What is important is to be consistent so you can spot trends. I test at 90 minutes, but I also test at 2 hours to see how well I am dropping, and if I am not dropping enough, I test again at 2 and a half hours..
 
Thanks folks. I don't understand why they don't have the info on the website or perhaps it's there somewhere and I'm just not able to find it

Hello Shire and welcome to the Forum Here is the Basic Information we give to new members and I hope you will find it interesting and useful. I hope this will help to answer your questions too. Ask more questions when you need to and someone will help.


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.

  • Low Carb Program - it's made front-page news of the New Scientist and The Times. Developed with 20,000 people with type 2 diabetes; 96% of people who take part recommend it... find out why

  • Hypo Program - improve your understanding of hypos. There's a version for people with diabetes, parents/guardians of children with type 1, children with type 1 diabetes, teachers and HCPs.
 
I normally test before eating then at 2 hours from first bite but also I often test at one hour also that is because I like to see what the peak reading was as I normally peak at about one hour most people would say it's not required to test at one hour but I like to have as much data available as is possible.
