can someone explain this to me please?,
My blood sugar reduces after I eat (depending what I've eaten!) but when I wake it's 12+, and that's fasting, I'm confused!

If you haven't eaten for a long time say 5 or 6 hours your liver provides you with sugar to keep you going until you eat again. In your case it seems to do just that but it results in a high of 12+ so we are talking diabetes here.

As for reducing after you eat, there is a little ambiguity here. Do you mean it reduces to normal levels given time or just keeps going down. If the latter then there is a problem.

This morning I woke with a 13.8 blood sugar reading, came downstairs and at 9am had a glass of water and half a grapefruit that went to 14.8, then an hour and a half later at 10.30 I had a slice of bacon with an egg it went down to 9.3, I don't understand how it goes down after I've eaten like this morning.
Can you shed some light on this?
I am type 2 and on saxagliptin 2.5 mg

Your hba1c is probably giving you a diabetic level and your fasting level is dominated by dawn phenomenon most certainly but the lows you are getting is probably the gliptin and that is designed to bring your blood glucose levels down.
You will have to speak to your GP.
What are you eating to come to the conclusion that that's what is dropping your levels?
Hope this helps.

These are my last 5 days of glucose readings
(If that helps)
14.0 After eating baked potato and chicken salad
12.2 on waking
10.8 after dinner of chicken fillets and veg
10.5 before bed
11.2 on waking
10.8 after breakfast of egg
10.2 BEFORE lunch
11.5 BEFORE dinner below!
10.8 after dinner of chicken and rice
9.1 on waking
12.6 lunchtime (not hungry so no lunch)
11.6 after dinner of chicken, sausage BBQ and some salad
8.3 at 10.30am fasting
13.3 last night after dinner of fish and salad
13.8 on waking
14.8 after grapefruit
9.3 after bacon and egg

I wonder if protein brings it down, but why?

I don't find any of those readings particularly low and it makes me ask myself where you are getting the sugar from. Your liver store is working well so that's one place. The baked potato might have been a mistake as was the rice and whatever you ate the sausage in. As Nosher said, the grapefruit could have been another mistake especially if you are one of the people that put sugar on it.

If those readings were mine I would be thinking of cutting the carbs a lot more and going for walks more often.

Hi
The sausage wasn't in anything as I'm wheat intolerant so I just had it with the chicken and salad from the BBQ, the baked potato may be a factor as I felt very tired after eating it.
I should have said the rice was 'cauliflower rice' blanched and blitz in processor to make 'rice' not regular rice, I'm so used to calling it rice that i forget that others think I refer to normal grain rice.
I walk around the whole of Southwold each day with my daughter. What carbs do I have? Am I missing something?

To be normal readings at fasting is between 4 - 6mmols.
Your readings are not particularly low.
The reason that you are getting lower readings is the natural fats in protein are slowing your digestion rate down and protein has very little of carbs. In the period between fasting test and your testing after, you are probably rising and then going lower as there is not many carbs in your meals.
Everything is nomal for a diabetic with your range of readings.
You are doing everything you can, reducing carbs, exercise and testing.
The meds will work and you should get your blood glucose levels down.
Patience is required, and a couple of tips.
Eat regularly and eat little and often as long as it's low carb.
Are you getting more natural fats into your meals.
Such as butter, cream, full fat yoghurt etc?

These are my last 5 days of glucose readings

sounds like you need to speak to your diabetic team. Those readings are too high and will cause long term complications.
Perhaps taking a background insulin like tressiba once a day may help? Its peakless insulin so may help with your high morning readings. (Called dawn phenomenon)

I'm cows milk intolerant and soya is naturally high in sugar so I have skimmed goats milk and goats butter, I grill everything I don't fry, I eat poached eggs and the bacon I eat is grilled.
I don't eat yogurt no as it reminds me of when my baby's puked up milk, kind of puts me off.

Would you think that I should eat full fat milk etc? I use goats butter which is full fat.
I currently have skimmed Goat milk, is that what I'm doing wrong?

Thanks,
I have an appointment Thursday morning to see the diabetes specialist from the hospital.

You need full fat, low fat has mostly sugar substitute instead.
You want to fuel your body with natural fats rather than carbs or sugars.
I fry my eggs and mushrooms and my burgers etc in coconut oil or even duck or goose fat, I do grill but only gammon or bacon and I eat the fat or rind!
I don't do dairy either, but I'm weird! But not intolerant!

You have to eat what is right for you and test and test and eat to your meter.

Ok, I will try that until Thursday and see if it works, hopefully in 4 days I should see a difference.

Hi
Well I have an update for everyone,
I went to see the specialist and he has put me on gliclazide and ramapril, since taking it my blood sugar has dropped from 19 down to approx 5-6 during the day and about 6-7 overnight, for me that's good but since being on gliclazide and as I didn't usually eat carbohydrate as such I had an awful hypo, very scary and for two days afterwards my head hurt so badly that I felt like I'd been hit by a bus. Since this not so nice event I've tried to eat a few carbs instead of just protein and vegetables for dinner and it is working, I feel so much better I'm not exhausted all the time, I'm not thirsty and I have so much more energy.
I would definitely tell people with awful T2 levels to consider this, I was told that it can make you put weight on, so far I've been ok.
I feel amazing!
