The Role of Adipokines and Gene Polymorphisms in the Development of Obesity- Induced Depression.

Purpose of review: This review examines the role of adipokines and gene polymorphisms in the development of depression and obesity. It is of great importance to understand the mechanisms that may be effective in the development of obesity and depression as their incidence increases.

Recent findings: Adipokines are released from adipose tissues and primarily regulate the connection between the metabolic and inflammatory effects of obesity and the brain cells and adipose tissue. Adipokines may potentially contribute to the pathophysiology of depression by influencing the HPA axis and neurotransmitters. According to some estimates, the genetic overlap between obesity and depression is as high as 12 percent. Furthermore, these genes may be linked to significant interconnected signaling networks that have a role in the etiology of both disorders. Obesity and depression are both on the rise globally, and it is thought that there is a bidirectional relationship between these two conditions. Obesity and obesity-induced depression seriously limit the psychosocial functionality of individuals and impair their quality of life. Having a high body mass index (BMI) raises the likelihood of developing depression. On the other hand, as the BMI elevates in people suffering from depression, the possibility of developing obesity also rises.
