Patients with fatty liver disease should also appropriately quit smoking or reduce the frequency of smoking. The treatment for severe fatty liver disease mainly includes a reasonable diet, appropriate exercise, as well as choosing to quit smoking and drinking, controlling diet properly, increasing physical exercise, removing the cause of the disease, and actively treating the primary disease. Although smoking mainly causes damage to the lungs, nicotine in cigarettes can also damage liver cells. When people with fatty liver disease smoke excessively, it can exacerbate the condition. It also damages liver cells, so people with fatty liver disease also need to quit smoking or reduce the frequency of smoking. People with fatty liver disease should regularly monitor liver function and undergo imaging tests of the liver to timely monitor the condition and actively enhance physical exercise to control the cause of the disease.
