Obesity and depression are typically comorbid with complicated bidirectional relationships that add to the physical and mental health consequences. Biological factors involve persistent low-grade inflammation, disruption of the hypothalamic–pituitary–adrenal axis, altered neurotransmitter activity (serotonin and dopamine), and metabolic alterations, which might exacerbate depression symptoms. Psychosocial factors such as weight stigma, low self-esteem, social isolation, and functional restrictions enhance sensitivity to mood disorders. Depression can impair motivation to exercise, alter sleep and appetite, and cause poor eating practices that contribute to weight gain and obesity.

Obesity-related pain, concomitant diseases (diabetes, cardiovascular disease), and repeated dieting failures can also instigate or worsen depression. In clinical practice, patients typically come with overlapping symptoms such as fatigue, sleep disturbance, and anhedonia, which complicates the diagnosis and selection of treatment. The best results are achieved with integrated treatment for both mood and metabolic health: combining lifestyle interventions (structured exercise and nutritional counseling), behavioral therapies (CBT, interpersonal therapy), and careful pharmaceutical selections to minimize weight gain. Individualized programs are supported through collaboration between primary care, mental health, nutrition, and rehabilitation specialists.

Early screening for depressive symptoms in adults with obesity—including weight considerations in patients with depression—enhances identification and facilitates early and complete care.
