For over a decade, Cummings and others have tried to reframe the very concept of bariatric surgery (they prefer “metabolic surgery”). Their work has shown these procedures just don’t change how much food the stomach can fit; they trigger a cascade of metabolic and bodily changes, many of which help people with type 2 diabetes naturally get their blood sugar under control. Some changes even start happening before a patient loses weight, such as higher levels of peptide production in the gut that seem to restore a patient’s sensitivity to insulin.
If you have type 2 diabetes and your body mass index (BMI) is greater than 35, you may be a candidate for weight-loss surgery (bariatric surgery). Blood sugar levels return to normal in 55 to 95 percent of people with diabetes, depending on the procedure performed. Surgeries that bypass a portion of the small intestine have more of an effect on blood sugar levels than do other weight-loss surgeries.
Random blood sugar test. A blood sample will be taken at a random time. Blood sugar values are expressed in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). Regardless of when you last ate, a random blood sugar level of 200 mg/dL (11.1 mmol/L) or higher suggests diabetes, especially when coupled with any of the signs and symptoms of diabetes, such as frequent urination and extreme thirst.
The earliest oral diabetes drugs were the sulfonylureas. These work by stimulating the pancreas to produce more insulin. The oldest of these drugs still on the market is chlorpropamide (Diabinese), which has been used for more than 50 years. The second-generation sulfonylureas are taken once or twice a day. They include glipizide (Glucotrol, Glucotrol XL), glyburide (Micronase, DiaBeta, Glynase), and glimepiride (Amaryl).
You should have no more than three of these “feeding times” per day. The reason limiting the number and duration of your meal times is so important has to do with staying out of the vicious cycle of increasing insulin resistance. To get smart on insulin resistance — the cause of both type 2 diabetes and obesity — read Dr. Jason Fung’s book, The Obesity Code: Unlocking the Secrets of Weight Loss, or watch his free lecture on YouTube.
