9.1 before breakfast but it was 7.1 before I went to bed? I get readings of between 5-8 during the day. Why does my reading go up over night?

Hi @lgs - welcome to the forum!
It's called Dawn Phenomenon or liver dump. As your BGs drop overnight your liver releases stored glucose into your system to prevent levels from falling too low. It's a normal reaction whether you are diabetic or not, but it can be very frustrating if you are trying to maintain low BGs. The more glucose stored in your liver, the higher your readings are likely to be. Many members have found that following a low carb, high fat diet - as outlined here on the website - can reduce your glucose stores and bring these readings down to a consistently lower level.
I'm tagging @daisy1, who will send you some more information which may be of help.
Good luck with your journey - keep posting and sharing!

Hello and welcome to the forum :) I have moved your post and reply to a new thread so you will get replies on this one. Here is the information we give to new members and I hope you will find it useful. Ask more questions when 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 210,000 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.

9.1 before breakfast but it was 7.1 before I went to bed? I get readings of between 5-8 during the day. Why does my reading go up over night?

I experience this. Readings fine when going to bed, at least 2or 3 higher in the morning. Lucky if it's in single figures! Frustrating isn't it? Hoping there's not too much left in my liver to 'dump' but at least it shows it's working.
 
Thanks and yes it is frustrating. Also if I measure 2 hours after eating it's high (around 10 or higher) but 4 hours it's in the 5's during the day. So this is normal and is due to the liver? I have only changed my diet dramatically 4 weeks ago after getting every scary readings and advice. So when you say your liver is dumping do you mean by diet and exercise?
 
The liver stores glycogen and adds it to your system in the form of glucose if the signals tell it you need extra energy. A reading of 10 at the 2 hour mark after eating means your spike at 1 hour is probably much higher. This is due to the food you are eating and not your liver. Try testing at 1 hour to check. If you have not already started a low carb diet then you might want to look into it as it is the most effective way to get your sugars under control. I will tag @daisy1 to send you information that newcomers receive. My best advice is to read it all carefully and follow the links. There is a link at the bottom of it that takes you to the low carb program. Once you have read it please ask any questions you have and someone will answer. Welcome to the forum.

Thank you and I look forward to the information. I have already started (3 weeks ago) a low sugar eg everything under 1% or zero including lactose free milk and zero alcohol but welcome any more advice.
