[Bariatric surgeries at diabetic patients]

Area of Science:

• Metabolic Surgery
• Endocrinology
• Cardiovascular Medicine

Background:

• Rising global rates of obesity and type 2 diabetes mellitus (T2DM) present significant medical challenges.
• Cardiovascular complications are a major concern associated with T2DM and obesity.
• While pharmacotherapy has advanced, bariatric surgery offers superior outcomes for T2DM management.

Purpose of the Study:

• To review the indications for bariatric surgery in patients with type 2 diabetes mellitus.
• To discuss the efficacy and mechanisms of various bariatric procedures on metabolic health.
• To outline long-term follow-up strategies for diabetic patients undergoing bariatric surgery.

Main Methods:

• Review of current medical literature on bariatric surgery and type 2 diabetes.
• Analysis of evidence supporting surgical interventions in different obesity classes.
• Discussion of comparative effectiveness and mechanisms of action of various bariatric operations.

Main Results:

• Bariatric surgery significantly reduces body weight and improves glycemic control, leading to diabetes remission in many patients.
• Current guidelines recommend surgery for severe obesity, but evidence supports its use in lower BMI categories with T2DM.
• Different surgical procedures exhibit distinct mechanisms contributing to positive metabolic effects.

Conclusions:

• Bariatric surgery is a highly effective treatment for type 2 diabetes mellitus, offering significant benefits beyond weight loss.
• Expanding indications for bariatric surgery in T2DM patients, even with lower BMI, is supported by growing evidence.
• Understanding the mechanisms of action is crucial for optimizing patient selection and surgical approach.
