Relação entre Tabagismo, ganho de peso e fatores mentais

Abstract

Objective: The study investigated the relationship between smoking, mental disorders and weight gain when quitting smoking, seeking to improve existing treatments. Methods: This is a literature review based on articles from the PUBMED and LITMAPS databases, in English and Portuguese, published between 2014 and 2024. The search used keywords such as smoking, depression, anxiety, and weight gain. Results: The studies analyzed the interaction between smoking, psychological factors, and the challenges of cessation. They found associations between smoking, anxiety and depression, as well as weight gain after quitting, although this is usually minimal. Cessation programs face challenges such as high failure rate, low motivation, and anxiety. The conclusions highlight the importance of integrated approaches that consider physical and psychological aspects in the treatment of smoking. Conclusion: The analysis revealed that smoking is associated with psychiatric disorders such as anxiety and depression, and is especially prevalent in patients with panic disorder. Quitting smoking frequently causes weight gain, but this can be managed with proper follow-up. The findings emphasize the need for integrated approaches to treat nicotine addiction and mental health problems, as well as weight management strategies. Keywords: Smoking, Depression, Anxiety, Weight gain.
