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.
Diabetes is a group of diseases characterized by elevated blood glucose levels due to defects in insulin secretion, insulin action, or both. According to the American Diabetes Association (ADA), type 2 diabetes usually begins with insulin resistance. For those people whose bodies resist insulin, the pancreas secretes extra insulin to maintain normal glucose levels. As the condition progresses, insulin production gradually decreases and eventually reaches a level of deficiency that can no longer maintain blood glucose in the normal range. But how type 2 diabetes presents and progresses can vary considerably, as noted by the ADA, and methods of treatment can vary from patient to patient.
