Patients should be made aware of the connection between smoking and vitamin D levels and MS, and providers should work to empower patients to make appropriate lifestyle changes. In order for patients to make lifestyle changes that are necessary for their health, they need to be educated about the consequences of the choices that they make. Providers should provide patients with information and resources about the benefits of changing their lifestyle. Quitting smoking is incredibly challenging. Many people who have tried to quit in the past without success may feel that they are unable to do it. Encouragement, reassurance, understanding, and providing resources can help them realize that they do in fact have the power to make these changes. These changes could not only slow MS progression, but also prevent patients from developing other complications as a result of smoking or being deficient in Vitamin D.
