Background: Heart failure with preserved ejection fraction (HFpEF) is a common obesity-related complication that often develops before symptoms. Body mass index (BMI) poorly captures visceral adiposity, the metabolically active fat linked to cardiometabolic dysfunction, myocardial remodeling, and diastolic dysfunction. Waist circumference (WC) is a simple, inexpensive surrogate but remains underused.
Objectives: This review summarizes evidence linking central adiposity to left ventricular diastolic dysfunction (LVDD) and HFpEF and proposes a practical framework for integrating WC into routine vitals to enable earlier risk stratification and prevention.

Type 2 diabetes has traditionally been framed as a disorder of hyperglycemia caused by insulin resistance (IR) and progressive beta-cell failure. That model remains biologically useful, but it is clinically incomplete.

Sleeve gastrectomy is a vertical gastric resection with tubulation of the residual stomach. It is an irreversible procedure, which causes a marked reduction in appetite and early satiety, with consequent significant weight loss (>70% excess weight).

The purpose of this literature review is to investigate the effectiveness of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) compared with metabolic surgery in achieving weight loss among individuals living with obesity and type 2 diabetes (T2D) mellitus.

Sleeve gastrectomy (SG) is now a widely performed bariatric procedure; however, staple‐line leaks remain a challenging adverse event. This study evaluates leak rates, management strategies, and weight loss outcomes after ambulatory laparoscopic SG.
