Hi - you don't say what you have been eating which is part of looking after your diabetis. Suggestions that seem to work are low carbing as not only does your body not cope with sugar but carbs as these turn to sugar.
I was diagnosed Type 2 in March of this year, and you should have been told to see the Diabetic Nurse who should then advise you on what foods you can and can't eat. You should then test yourself (it is suggested before a meal and 2 hours after and your reading should be no higher then 8.5).
You need to cut out straight away all sugar, white bread and other starchy foods and look at what you are eating. Veg that grows in the ground like carrotts etc have a lot of sugar in them (I know I thought they were healthy eating) Anything that is high in carbs try not to eat if you do eat have a very small portion.
Hopefully the adminstrator of this forum will reply with their message that they give all newbies and also if you look at this forum especially the low-carb one it might help you.
I have porridge made with water and add a little milk to cool it for breakfast - some people can't eat porridge as their bodies react different to mine. I find breakfast the hardest as I used to love my toast.
I eat a lot of chicken salads. I have found that 3 small NEW potatoes have a bad reaction on me but i had some mash potatoes made from Red potatoes the other day and my reading was 7.1.
Everybody is different so we need to test and see what effect each food we eat will have on our Blood Sugar.
You obviously have not been told how to control your blood sugar. If your doctors surgery does not have a diabetic nurse and you have no support then I would look to changing doctors to one that does.
You must have been feeling quite ill on the readings you have. They may just give you a dose of insulin to reduce your BS level and I would certainly talk to the doctor at the hospital on how to cope with your diabetics and ask them for advice on how to cope with it. They may need to change your medication also to help you. But this is a serious condition so have a look around the different sites/topics on here and it will really help you.
I really do wish you well and hope that all ends up better for you.
Sue
