Even as things stand now, there are a lot of people left out in the cold. A 2016 study, for instance, found that only 41,000 people with diabetes annually get bariatric surgery in the US—fewer than 5 percent of the total new cases diagnosed every year. And the longer someone has diabetes, studies have suggested, the less likely they are to go into remission if they eventually get surgery. Getting those numbers up will not only require changing the minds of insurers, but public opinion, too.
Dr. Fung says he decided to experiment with intermittent fasting because he was frustrated seeing so many diabetic patients with kidney failure. “It occurred to me that fasting was an underutilized therapeutic option for losing weight,” he recalls. “I started doing this five years ago, and a lot of people got incredibly good results – it reversed their diabetes.”
Aside from the financial costs of diabetes, the more frightening findings are the complications and co-existing conditions. In 2014, 7.2 million hospital discharges were reported with diabetes as a listed diagnosis. Patients with diabetes were treated for major cardiovascular diseases, ischemic heart disease, stroke, lower-extremity amputation and diabetic ketoacidosis.
Diabetes is a disease in which your blood glucose, or blood sugar, levels are too high. Glucose comes from the foods you eat. Insulin is a hormone that helps the glucose get into your cells to give them energy. With type 1 diabetes, your body does not make insulin. With type 2 diabetes, the more common type, your body does not make or use insulin well. Without enough insulin, the glucose stays in your blood. You can also have prediabetes. This means that your blood sugar is higher than normal but not high enough to be called diabetes. Having prediabetes puts you at a higher risk of getting type 2 diabetes.
