Obesity and Cardiovascular Risk After Quitting Smoking: The Latest Evidence

Smoking cessation is one of the most effective ways to reduce cardiovascular risk. However, weight gain and abdominal obesity generally occur after quitting smoking, as a result of nicotine withdrawal. Obesity increases various inflammatory markers, and weight gain after smoking cessation temporarily increases the risk of diabetes and reduces the benefit gained by smoking abstinence. The benefits of smoking cessation may be minimised by obesity in those who have stopped smoking. Pharmacological treatment with medications such as nicotine patches and varenicline is useful to suppress weight gain during smoking cessation. Supporting patients to continue smoking cessation and to gradually decrease their weight will be crucial.
