The islets of Langerhans are responsible for the endocrine function of the pancreas. Each islet contains beta, alpha, delta, and pancreatic polypeptide (PP) cells that are responsible for the secretion of pancreatic hormones. Beta cells secrete insulin, a well-characterized hormone that plays an important role in regulating glucose metabolism.
For individuals with type 2 diabetes mellitus, achieving and maintaining a healthy body weight is a cornerstone of effective blood glucose management.12
Weight loss improves glycemic control through several key mechanisms:
- Enhanced Insulin Sensitivity: Reducing excess body weight can lead to improved insulin sensitivity, which allows the body to better regulate blood glucose levels.1
- Restoration of Metabolism: Significant weight loss, particularly when combined with regular exercise, can help restore normal glucose metabolism.1
- Rapid Hyperglycemia Reduction: In patients who are obese or overweight, even short-term caloric restriction can result in a considerable improvement in hyperglycemia.1
When weight loss is paired with physical activity, the benefits are compounded; exercise further promotes the uptake of glucose into muscle cells, which helps blunt the rise in blood glucose levels that typically follows the ingestion of carbohydrates. These lifestyle interventions are essential for reducing symptoms and lowering the risk of long-term complications associated with the disorder.12
