Ok, now I get it... You're in the UK, right? You measure blood glucose differently than we do in the states. You stated that you think you have diabetes because you never read labels or exercise... that is only part of the picture. Your body was predestined to get diabetes from birth under the circumstances you live in... and because of the society we live in where abundant calories are readily available with little or no energy output to gain them... you are headed toward diabetes. Please don't be upset with yourself. If you had to do physical labor to produce the food you eat, that is, feed and milk the cows and butcher the meat, and grind the wheat and dig the vegetables or climb the fruit trees you would be just fine. All we need to do is drive (not walk or ride a bike) to the store, use a push cart (not carry) the food, and drive it home. We have power mowers, power saws, self propelled vacuum cleaners, dishwashers, washing machines, all kinds of 'labor saving' devices. This is part of the reason we have such an upswing in the world diabetes population.
As we have specialized our jobs in society some of us lead very sedentary lives. We need to find ways to increase our exercise to keep our bodies running the way they were designed to run. Try walking more briskly than you have been doing. If possible, walk where there are hills. Try not to walk in the city by large and busy roads. The air quality is not good for exercise around traffic. I use swimming laps as my exercise. It's easy to burn lots of calories and I enjoy it a lot. Climbing stairs is great for cardio, but check with your doc before you really start an intense exercise program. You don't list your age or whether or not you have any other health problems so I don't want to get you headed in the wrong direction.
Dietary education and understanding of blood glucose are two of the main things you need to learn about to stop this diabetes in its tracks. One of the net's sites that I often go to for information is: netdoctor.co.uk
. You could visit that site and see what you can learn there. Hope this helps.
