I had oatmeal a little milk and a few berries for breakfast. 20 minutes after eating my bs reading was 9.4. instrumental ringtones - After two hours it was down to 6.3. free iphone ringtones -My doctor says only take a reading two hours after eating. If I did this I would not know that it went up after this meal. Is he trying to say that spikes after meals don't count and just be concerned about the two hour after reading? Is this so? I would think the 9.4 would make my AIC reading higher overall. I noticed that my reading isn't as high if I have the exact same breakfast but add eggs. bad moms movie - Should I eat oatmeal at all?

The only official guidance is that you are OK if your reading is less than 8.5 at the two hour mark. I don't know where that information originated from or even if it is true but your doctor is probably using it for guidance.

It is true that if you eat your blood sugar will rise. It is also true that high blood sugar is damaging. Lots of people do their own thing and use their meter to find out exactly when they peak and whether they should do anything about it. You can obsess too much about these finer points but it is entirely up to you what numbers you use and how far you go in investigating this.

Personally I think your numbers are good and I don't think I have ever tested just 20 minutes after eating.
 
I personally do not like to go that high after eating. Oatmeal is something that many people cannot tolerate well because it tends to spike them high. It is up to you to decide how high you are comfortable with. I will tag @daisy1 to send you the newcomer welcome package. It is full of excellent information and well worth a thorough read. Welcome to the forum.
 
@NicoleJS

Hello Nicole and welcome to the forum :) Here is the information we give to new members and I hope you will find it useful. It will give you, among other things, information on reducing carbs in your diet 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 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 147,000 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.

I think the figure for type 2 two hours after eating is now 7.8. Damage to internal organs is obviously worse, the higher the reading; and I personally like to try to see numbers under 6.
 
@dbr10 It all depends on whose guidance you choose to adopt. For example. The ADA say

1-2 hours after beginning of the meal (Postprandial plasma glucose)*: Less than 180 mg/dl That’s 10 in English.

or if you prefer Australia

It's 6-10mmol/l two hours after starting a meal.

Or good old UK

Type 2 diabetes (Diabetes UK Council of Healthcare Professionals 2015)**

· before meals: 4–7mmol/l

· two hours after meals: less than 8.5mmol/l.

https://www.diabetes.org.uk/Guide-to-diabetes/Monitoring/Testing/

My point is that we seem to get many bits of advice that vary on this topic and none of them seem to backed by any research that I know of so you might just as well invent a figure of your own and go for it.
 
The best overall view on the effects of higher numbers after eating is on the www.bloodsugar101.com website.

The author (Jenny Ruhl) draws together what research has been done on the subject, discusses it, and allows you to decide where you want to aim your numbers.

Me? I read her figures and thought 'goodness, no wonder all these government bodies tell us that D is a progressive disease! They tell us that our blood glucose is OK when it REALLY isn't - which is what causes the progressive damage.'

As a result I try not to go above 7mmol/l at any time.
Being human, I fail quite regularly, but the goal/result is a non-diabetic HbA1c, which is below where the damage happens- which should prevent that dreadful NHS progression.
 
@dbr10 Under 6 after meals is a very hard target for anyone not on insulin or strong drugs. Do you reach your target most times?

I don't think it is a question of "how high" it is, more a question of "how long it stays high". The longer it is high the more damage is being done. By "high" in this context I mean higher than 7.8 (supposedly the non-diabetic recommended level at at least 90 minutes). My personal target is under 7 at all times, but being human this doesn't always happen.

Yes, you're quite right. It is how long you stay high. I do manage these numbers quite often, but not all the time, by any means. I take Metformin and try to be as low carb as possible. Must admit I do panic a bit if the readings are higher, even though NICE reckons they are okay. I tend to think diabetes is not treated agressively enough by HCPs, and the figures they tell us are okay, aren't. Bernstein talks about doing all you can through diet, exercise and medication, to normalise BG levels.

Yes. I know what you mean. But I'm strongly influenced by Jenny Rhule in her book, and of course, Bernstein when she suggests that problems occur as BG rises above around 6 and stays there.

Yes. I completely agree with you.

I have the greatest respect for Jenny Ruhl but it's just another target which a person can adopt or not as they choose. There is nothing compulsory about any of them.
 
My own goals are never above 7.8, and AM fasting numbers around 4.4. I'm there 100% of the time (rounded to the nearest tenth of a percent). Most of the time I'm below 7.0. If I'm between 7.0 and 7.8 it means I've eaten a meal witin the last 2 hours that had around 20 net carbs in it.

I would not personally be comfortable eating new (thus unpredictable) foods without testing before, at 1 hour, 2 hours, and (if 2 is higher than 1) at 3 hours. The change in my mental state is obvious to close observers when I hit the 7.2 range, so it is pretty clear that it is not personally healthy for me to spike to 9.4, even if I drop back into the "acceptable" range within the designated 2 hour period.
 
Daft question.. Does it really matter that oatmeal sends it high. If it comes down within 2 hours?

There's evidence that wild swings in BG are what cause damage. There's also evidence that any reading above 7.8 is causing damage somewhere in the body. So, in my opinion it does matter.
 
How much damage can be caused in 2 hours?

I am honestly interested.

I don't think it's what happens in 1x 2 hour period - it's the accumulation of damage over a lifetime. Here's an article about levels above 7.8:

http://www.phlaunt.com/diabetes/14045678.php

Quite a few people already have damage before they're diagnosed - I know I had neuropathy in my feet, but it happened so slowly I didn't recognise it for what it was.
 
I get the long term of being high.

But the short term spike, surly can't cause damage can it?
