Area of Science:

• Psychoneuroimmunology
• Metabolic Health
• Social Determinants of Health

Background:

• Loneliness is a subjective experience of unmet social needs, distinct from being alone.
• It is a measurable psychological experience linked to adverse health outcomes.
• Existing research highlights pathways including poor health behaviors, heightened stress, and impaired physiological repair.

Purpose of the Study:

• To present loneliness as a distinct psychological experience and health determinant.

Main Methods:

• Literature review and synthesis of existing research on loneliness.
• Analysis of pathways linking loneliness to immune and metabolic dysregulation.
• Conceptualization of loneliness as a syndrome of immunometabolic pathology.

Main Results:

• Loneliness significantly impacts immune regulation, affecting cytokines, growth factors, and immune cell activity.
• Metabolic dysregulation includes altered glycemic control, lipid metabolism, and cardiovascular function.
• These effects collectively point towards a complex interplay of immunologic and metabolic disturbances.

Conclusions:

• Loneliness extends beyond psychosocial factors, encompassing a complex set of systemic alterations.
• The concept of an
