Hi, welcome to healthcare magic
tends to be a progressive disease and so treatment often may start from lifestyle and one mediacation and eventually progress to needing insulin
The rate at which this occurs varies in different persons and may depend on previous blood sugar control (the harder the pancreas
which is the organ that releases your body's insulin, has to work the faster it burns out and the earlier insulin treatment is needed).
Your blood sugar goals may vary according to your national guidelines. In the US the goals are as follows:
of less than 7% ( some institutions in the US want it to be lower than 6.5%).... every diabetic should have this test done at least every 3 months, it allows the doctor to determine what the blood sugars have been over the previous 3 months
Before meals blood sugar between 70 to 130 mg/dl
After meals : less than 180mg/dl
To acheive these levels you would need to adopt lifestyle changes such as increased physical activity and change in diet with reduced consumption of refined carbohydrates ( sodas, juices, cakes , pastries, white flour, white bread, white rice, white pasta) and increased use of water, vegetables, fruits, brown grains , wheat, non refined oats.
In addition , as you suggested, eventually the mediation has to be altered with increased dose or adding another medication to acheive control.
You should consider speaking to your doctor, do readings at different points in the day to assess overall control and to determine which part of the day may have the worse or best readings, take these readings to your doctor who may then decide that the medication may need to be augmented.
Remember in diabetes it is not just important for the blood sugar to be in control, but you need to acheive blood pressure and cholesterol
control as well, there are certain targets for persons with diabetes.
I hope this information is helpful to you and I hope that you acheive blood sugar control
