These studies suggest that treating type 2 diabetes involves a combination of lifestyle changes, medications like metformin and GLP-1 RA, and potentially novel treatments such as adipokines and dual GLP-1/GIP agonists.

Diabetes management requires a multifaceted approach that includes lifestyle modifications, pharmacological interventions, and sometimes surgical options. The goal is to maintain optimal blood glucose levels, reduce complications, and improve the quality of life for patients.
Lifestyle interventions are the cornerstone of diabetes management. Intensive lifestyle interventions (ILI) that include diet and exercise have been shown to significantly improve glycemic control, insulin sensitivity, and overall physical health in older adults with diabetes. Regular physical activity, such as at least 150 minutes per week, combined with a low-fat, reduced-calorie diet, is recommended to achieve and maintain weight loss and improve cardiovascular health.
Weight loss is crucial for improving insulin sensitivity and reducing the risk of complications. Studies have shown that lifestyle interventions can lead to significant reductions in body weight and visceral fat, which are associated with better glycemic control and reduced insulin doses.
Metformin remains the first-line oral treatment for type 2 diabetes due to its efficacy, cost-effectiveness, and ability to decrease hepatic glucose output and improve insulin sensitivity . It is often used in combination with other medications to enhance glycemic control.
Glucagon-like peptide-1 receptor agonists (GLP-1 RA) and sodium-glucose cotransporter-2 inhibitors (SGLT-2i) are newer classes of medications that offer significant benefits. GLP-1 RAs, such as semaglutide, not only lower HbA1c levels but also promote weight loss and have cardiovascular benefits . SGLT-2 inhibitors help lower blood glucose levels independently of insulin and provide cardiovascular and renal benefits.
Insulin therapy is often necessary for patients with type 2 diabetes, especially as the disease progresses and pancreatic beta-cell function declines . Newer insulin analogues, such as long-acting and short-acting insulins, offer better mimicking of physiological insulin release and reduce the risk of hypoglycemia . Combination therapies with insulin and other glucose-lowering drugs can also be effective in achieving glycemic control with fewer side effects.
For patients with severe obesity and type 2 diabetes, bariatric surgery can be a highly effective treatment option. It not only leads to significant weight loss but also improves glycemic control and reduces the need for diabetes medications.
The management of diabetes should be personalized based on the patient's characteristics, including age, comorbidities, and lifestyle. A stepwise approach that starts with lifestyle modifications and progresses to the addition of oral antihyperglycemic agents and insulin as needed is recommended. Personalized treatment plans can help optimize glycemic control and reduce the risk of complications.
Effective diabetes management requires a combination of lifestyle interventions, pharmacological treatments, and sometimes surgical options. By tailoring treatment plans to individual needs and utilizing a stepwise approach, healthcare providers can help patients achieve better glycemic control and improve their overall health.
