HI there, I understand your frustration, docs are sometime rubbish at explaining why they are asking you to do something!
My doc said each Metformin drops your sugar by 1. It helps the body use sugar more effectively, doesn't make you gain weight and increases your sensitivity to insulin.
Its actually more like .5 mmol/L per 500mg tablet as the max dose of 2000mg (4 x 500mg) will only help to reduce bg levels by between 1 and 2 mmol/L.
That said it does help and as Jane mentioned it will help to reduce appetite, prevents the liver from releasing too much glucose and also helps to your body tissue absorb glucose more effectively. It has also been proven to help protect against certain cancers and cardiac problems as well so all in all it is usually considered by most as being very beneficial to T2 diabetics.
And as others have mentioned the best way to help get your bg levels under control is by looking at what you eat, basically all carbohydrates are turned into glucose (sugar) in the stomach and then that glucose is absorbed into the blood stream, therefore one way you can help to reduce your blood glucose is to reduce the amount of carbohydrate you eat.
Try testing before you eat and again two hours after finishing your meal, your bg levels should be returning to close to your pre meal levels at the two hour point. If there is a large difference say 8 mmol/L pre meal and 12 mmol/L two hours after your meal (postprandial) then that will tell you that that meal contained more carbs than you were able to eat safely.
What to do.
The next time you eat that same meal try reducing the carby part of that meal by say 50% and test again before and after eating, you should see a lower postprandial level this time, if it is still high then the next time you eat that meal test again before and after and once again if necessary, each time reducing the carbs until you reach a point where your levels are returning close to your pre meal level at the two hour point.
You will need to test every meal which will mean lots and lots of testing but once you get a feel for what works for you and what to avoid you can stop testing so frequently.
The main carbs to look out for are breakfast cereals, bread esp white bread, rice, pasta and all flour products, most people dont avoid these products completely but reduce them to a level that is right for them. Each one of us is different so no one can tell you what to eat or what to avoid some can eat one food that another will not be able to. This is why it has been found to be so important to test before and after eating. When you test at other times it just tells you how high your bg is but by testing before and after eating it becomes a tool for you to use to help you diet or change your lifestyle is an expression often used.
As regards exercise, gentle exercise is better than hard exercise as with any hard exertion your liver produces more glucose on demand to help your muscles cope with that exertion and that pushes your bg levels up, walking or swimming is great, aim to be slightly out of breath rather than panting for breath, that way your liver will not be asked to deliver more glucose than your muscles already have stored :thumbup:
Good luck and I hope you get those levels down soon :thumbup:
