Re: Will my husband's blood sugar ever be normal?
How much metformin is your husband taking? Can it be increased? If not, if he's already at the maximum dose and he's not seeing improvement, then it probably is time for insulin.
What many people do not seem to understand is that with Type 2, while it is initially caused by insulin resistance, for some people there is also a loss of insulin production, especially if it wasn't diagnosed early. That means that despite carefully monitoring carb intake, losing weight, and increasing exercise, the body still needs supplemental insulin. Please don't look at using insulin as a failure, but rather as a smart move to prevent the complications of uncontrolled diabetes.
Admittedly, there can be quite a learning curve when first going on insulin, what with figuring out the best type of insulin, the proper dosages, and how often to monitor blood sugar (often!), but it's worth it to avoid all those serious complications.
And counting carbs is important both for avoiding blood sugar spikes when not on insulin, and frequently important for figuring pre-meal insulin doses once you're using insulin.
