The overall goal of treatment with insulin (and other diabetes medicines) is to achieve the best match possible between the amounts of insulin given and the person's individual needs for insulin throughout the day and night. In this way, blood sugar levels can be kept as close to normal as possible to help avoid both short- and long-term problems from diabetes.
If you google “diabetes cure” you are directed to websites like WebMD and the Mayo Clinic where you find information on diet, exercise, medication, and insulin therapy, but nothing about the cure. This lack of information may have to do with the fact that Americans spend $322 billion a year to treat diabetes, $60 billion a year on weight-loss programs, and $124 billion a year on snack foods. This is about 3% of the US economy! Because so many peoples’ livelihoods are supported by diabetes and its main cause, obesity, the viral effect of people getting cured and telling others is greatly diminished.
