Depression in obesity

Abstract

The depression-obesity comorbidity represents a serious challenge for health and social care systems. In this chapter, we describe major depression, which is the most common type of depression, and we discuss the recognition of obesity as a chronic, serious, and complex health disorder rather than an imbalance between energy consumption and energy expenditure. Also, we portray representative evidence from epidemiological studies suggesting that obesity measures and obesity-related behaviors are linked to causal effects on depression and to increased risk of suicide ideation, attempts, or suicides. Finally, we highlight key facts dealing with depression in obese people treated or seeking treatment in bariatric surgeries. © 2021 Elsevier Inc. All rights reserved.
