| Summary: | Obesity, a global health concern of increasing significance, is characterized by chronic low-grade inflammation (LGCI) that significantly contributes to metabolic dysfunction. This narrative review explores the intricate pathophysiological mechanisms driving LGCI in obesity, emphasizing the role of adipose tissue, immune cell activation, and inflammatory signaling pathways. Hypertrophic adipocytes and infiltrating immune cells, particularly macrophages, release a cascade of pro-inflammatory cytokines, including TNF-α, IL-6, and IL-1β, creating a self-perpetuating cycle of inflammation. These mediators disrupt insulin signaling through JNK and NF-κB pathway activation, leading to systemic insulin resistance, cardiovascular complications, gut dysbiosis and other metabolic disorders. The review further discusses therapeutic strategies to mitigate obesity-related LGCI, focusing on lifestyle interventions, nutritional approaches, and pharmacological agents. Physical activity, specific nutrients, and dietary patterns can modulate inflammatory responses, while anti-obesogenic medicines and bariatric procedures offer additional avenues for intervention. By understanding and addressing the root causes of inflammation in obesity, healthcare professionals can develop targeted strategies to improve metabolic health and overall well-being of individuals with obesity and, ultimately, prevent and manage the wide-ranging complications associated with this condition. |
