Hi, I agree you do have a lot to learn and unusual or the odd high or low readings are usually because of either not washing hands, drying them, the calibration of the glucometer or the strips or you need to change the needle or are contaminated.

However, if not the glucometer.
The porridge and fruit are full of carbs, which would have been the cause of the high spike at 2hrs. Did you take a pre meal reading?

Do you know your hba1c test result?

I have also experienced the 'lo' reading on my glucometer.
But I have a condition that causes that!

Having consistent levels of blood glucose, is the best way to get control.
Reducing the carb amount in your diet is the best way to do this.

Having a food diary is essential, logging pre meal and two hours after first bite.
Then you can see which foods spike your blood glucose levels.
Like the porridge, it is supposed to be healthy, but not for you, if you get them results!
So, to stop them, you avoid these foods and eat something that doesn't do that to your blood glucose levels.

If you continue to have low readings (below 4mmols) then seek medical advice.

If you do have a low reading (hypo) take something quick acting to get you back up.


Let us know how you are doing.

Best wishes

Hi janstaz, blood sugars to vary a lot. It is great you have a meter and you are testing, Keep a diary of your results before and two hours after meals to see the patterns.

Very few people could test themselves at 1.7 so respectfully suggest that might be an error.

Many can tolerate porridge but not me that was my second highest ever reading at 13 second only to a Morrison's chinese takeaway.

Have you seen @daisy1 new members info?

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 questions and you will get some more replies.


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 245,000 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.

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

Being ill can wreck havoc with your BG levels - the T1 I care for normally ends up with raised levels whenever she's even just 'coming down with something'. Drink plenty of water and keep testing :)
