At present, there are 20 to 30 fatty liver patients among 100 ordinary adults worldwide, and the proportion is as high as 60% to 90% among obese patients. With the economic development and lifestyle changes, the number of fatty liver in China is increasing rapidly, and shows a trend of low age, now, the prevalence of fatty liver in coastal areas has reached 15%. Fatty liver not only damages the liver, but also often accompanied by abnormalities in glucose and lipid metabolism, which affects tissues and organs throughout the body. The incidence of metabolic syndrome, type 2 diabetes mellitus and coronary heart disease is significantly higher in patients with fatty liver. Some studies have shown that the life expectancy of patients with fatty liver is shorter than that of the healthy population, and the main causes of death are malignant tumors, cardiovascular diseases and cirrhosis. Is it advisable to lose weight? Often patients say: fatty liver is too much fat, that weight loss can not be cured. We can’t be too absolute, but for most patients with mild, moderate and a few patients with severe fatty liver, weight loss is the best strategy to reverse fatty liver. Losing weight is not just about dieting. Excessive dieting reduces the production of proteins that transport lipids, which in turn increases the accumulation of lipids in the liver. It is often said that you should keep your mouth shut and your legs open. Dietary recommendations for low-sugar, low-fat balanced diet, daily calorie intake should be reduced than usual 500 to 1,000 kilocalories; exercise to ensure that more than four times a week of moderate-intensity aerobic exercise, the cumulative exercise time of at least 150 minutes. The effectiveness of weight loss depends on the data. Determined to eliminate fatty liver through weight loss “aspirants” should always pay attention to their own body mass index (BMI = weight / height 2), in general, the body mass index should be reduced by at least 5%, in order to play a role in controlling fatty liver. To treat or not to treat? Most of the fatty liver patients are “quiet as a child, eating and flowing oil”, for them, eating less and moving more is difficult, not as easy as taking medication. Can hepatoprotective drugs cure fatty liver? In the clinic, patients often ask for liver-protecting drugs, which they mistakenly think can cure all diseases of the liver. Usually, liver-protecting drugs are only used in cases of abnormal liver function indexes, and their role in the prevention and treatment of fatty liver is still controversial, and it is not recommended that patients use these drugs routinely. Are health supplements useful? If the doctor does not prescribe medication, some patients will also buy health products and proprietary Chinese medicine to eat. Unbeknownst to them, even the best medicines can’t drive the fat out of the liver cells, not to mention that these health supplements with unknown formulations may cause damage to the liver function and aggravate the progress of liver disease. Most fatty liver stems from unhealthy lifestyle habits. The best treatment strategy is to control diet, stop drinking and exercise. On top of the popular “fatty liver tips” such as “eat a few spoonfuls of oil less and take a walk after meals”, some slightly more intense exercise should be added, and the goals to be achieved are a decrease in body mass index and a reduction in waist circumference. For patients with moderate or severe fatty liver disease, doctors may prescribe medications to prevent disorders of glucose and lipid metabolism and atherosclerosis depending on the specific situation.
