Hi. If you can let us know a bit more about his insulin regime i.e. types and number of injections per day we may be able to make some suggestions. If your husband is overweight and hence possibly taking quite large insulin units, then weight reduction by reducing carbs can enable the amount of insulin to be reduced and the blood sugar swings will get less. If he is normal weight perhaps we or his DN can still suggest a bit of re-balancing. I assume he carb-counts to decide how much insulin to inject for meals?
