Blood sugar after large meal

Hello all. Just trying to work out what is good and back blood sugar after eating.

Before I ate it was 5.6 and after it was 7.6 (an hour later).

I have 14 units of humilin before food in the evening and 2 units of novarapid. I've noticed my humilin is quite low for Type 2 (they don't know if it's type 1 yet until the tests come back but based on my diet before and age, they think it's type 2).

Is 7.6 after food considered a spike? I'm finding it hard to find any info on it.

I ate some sweet potatoes (probably too much), lots of cauliflower and broccoli and carrots and a steak. My treat for a Friday, I've eaten nothing I'm not supposed to since being diagnosed.

Cheers

Generally a rise of no more than 2mmol and ideally under 7.8mmol is the goal when testing after 2hrs - or so I’ve repeatedly been told in lots of places.

Sweet potato was likely the cause of most of that rise, followed by carrots but overall in range had the test been 2hrs rather than 1hr. Some foods rise quicker than others. I don’t use insulin so I’m not sure how that affects spikes etc but I’m sure someone will be along soon who can help.


I’ll tag @daisy1 for the welcome message she has for new members

How long have you been diagnosed? Where are you in the testing process?

Hello 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 need to and someone will try 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 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.

You may also be interested to read questions to ask at a diabetic clinic.

@ChuckingRox . Welcome to the forum.
It’s difficult to answer your question for two reasons at this point.
1. A definite diagnosis of type whether it be 1 or 2 is important to give advice.
2. Testing an hour after eating is a little bit to soon. Your blood sugars will still be reacting to not only the food but the insulin as well. 2 to 3 hours will give a better picture.
But and it’s only a but. As a type 1 I wouldn’t be to unhappy if my BS rose by that much if it continued to stay stable.
When you get a definitive diagnosis it’ll be far easier to help you.
Good luck.

Thanks for the replies guys. I checked it a couple of hours later and it was 5.6 and 5.6 again this morning at 12 (14 hours of fasting - it was Saturday morning and I had a lie in). It's odd, it's been 5.6 the last few times I've checked it before eating. I'm hoping that's a good sign.
