Unraveling the Association of Tobacco Smoking (Nicotine) with Gut and Adipocyte Appetite Regulator Hormones-A Systematic Review

Lifestyle behaviour is the cause of about 70%–80% deaths in developing countries. Risk factors, such as smoking, alcohol consumption, physical inactivity, obesity, and poor nutrition are the major causes of mortality that are crucial for researchers and policymakers to improve health and reduce preventable deaths in the developing countries. In specific, cigarette smoking has an inverse implication with body weight or body mass index (BMI). Smoking cessation has been linked to weight gain indirectly mediated through gut and adipocyte appetite regulating hormones. This systematic review is achieved through MEDLINE search to collect the data which support this idea using PubMed, Google and MEDLINE databases.
