Immunoinflammatory processes: Overlapping mechanisms between obesity and eating disorders?

Area of Science:

• Integrative biology
• Pathophysiology
• Developmental science

Background:

• Obesity and eating disorders (EDs) are complex conditions involving eating behaviors, often co-occurring.
• Evidence suggests shared alterations in immunoinflammatory processes in both obesity and EDs.
• Immunoinflammatory pathways are hypothesized to play a role in the pathophysiology of these conditions.

Purpose of the Study:

• To review the link between obesity and eating disorders.
• To focus on the role of immunoinflammatory processes in their pathophysiology.
• To discuss developmental factors contributing to this association.

Main Methods:

• Literature review of obesity, eating disorders, and immunoinflammatory processes.
• Exploration of genetic, epigenetic, and stress pathway influences.
• Discussion of early life development and its impact.

Main Results:

• Biological and developmental aspects overlap between obesity and EDs.
• Immunoinflammatory processes are implicated in the shared pathophysiology.
• Genetic, epigenetic, and environmental factors contribute to the link.

Conclusions:

• Immunoinflammatory processes represent a significant link between obesity and EDs.
• Developmental factors, including early life experiences, are critical.
• Biopsychosocial research approaches are needed to advance understanding and clinical practice.
