High body mass index (BMI) is a causal risk factor for a broad spectrum of chronic diseases, including cardiovascular disease, diabetes, chronic kidney disease, multiple cancers, and musculoskeletal disorders, resulting in significant global mortality and disease burden.
Maintaining a BMI within the 20-25 kg/m2 range is associated with the lowest all-cause mortality risk. This is not just about weight but about reducing the risk of major chronic diseases like heart disease, diabetes, and certain cancers. Public health surveillance and evidence-based interventions are critical to addressing this growing burden.
Epidemiological studies have identified high body mass index (BMI) as a risk factor for an expanding set of chronic diseases including cardiovascular disease, diabetes mellitus, chronic kidney disease, many cancers, and an array of musculoskeletal disorders.

More from this paper
- A significant portion of deaths related to high BMI occur among individuals who are not clinically obese (BMI < 30 kg/m2), indicating that overweight status (BMI 25-29.9) also carries substantial mortality risk.Strong
- Cardiovascular disease is the primary cause of death associated with high BMI, accounting for more than two-thirds of high-BMI-related deaths.Strong

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
