Good blood sugar control is important - the medication is one aspect, but the diet and exercising especially for overweight patients are also important aspects. Exercising address insulin resistance and helps thus to reduce the blood sugar levels in this way, apart from the benefits of weight loss, etc if you exercise enough. It can be a process to get to well controlled levels - a patient can, if educated, increase his own insulin untill they have reached controlled levels - maybe your brother can discuss this with his doctor. Otherwise if he is with a General practitioner he may request to be referred to a specialist with knowledge in diabetes care. It may be necessary to change his insulin regimen to another type of insulin - but his treating doctor must decide.
