脂肪肝

脂肪肝不是一种独立的疾病，是由诸多原因造成的。脂肪肝发病率的增高，与人们生活水平的提高和饮食结构的改变有着密切关系。包括营养失调、大量饮酒、糖尿病、肝炎、代谢和内分泌障碍等多方面的原因。肥胖是引发脂肪肝第一位的病因。长期摄入过多的动物脂肪、植物油、蛋白质和碳水化合物，这些食物在体内不能被充分利用，过剩的营养物质便转化为脂肪储存起来，导致肥胖、高血脂和脂肪肝。肥胖人数正以5年翻一番的水平增长。肥胖是非酒精性脂肪肝最常见和较肯定的危险因素，其发病率在50%-75%，重度肥胖者96%可发生脂肪肝。重度肥胖儿童脂肪肝的发病率高达80%，10个“ 大塊头

　　酒精是损害肝脏的第一杀手。由饮酒而引发的脂肪肝称为酒精性脂肪肝，70%-95%慢性嗜酒者有不同程度的脂肪肝。酒精进入人体后，在肝脏内经过一系列的生化过程，最终转化为甘油三脂。长期大量饮酒必然会有大量甘油三脂堆积在肝脏之中，逐渐形成脂肪肝。同时，酒精对肝细胞的毒性使肝细胞对脂肪酸的分解和代谢发生障碍，引起肝内脂肪沉积而造成脂肪肝。饮酒越多，脂肪肝也就越严重。每天饮酒，连续5年以上，即有发生脂肪肝的危险;每天饮酒为致肝纤维化和肝硬化的危险阈界，超过此阈界可使肝纤维化和肝硬化的发病率明显增加。有一项调查指出：20世纪60年代的酒精性肝硬化与其他病因的肝硬化相比，欧洲占42%，美洲66%，亚洲11%，, S生, S主, S版, S权, S
　　营养不良也会引发脂肪肝。肥胖者容易得脂肪肝，但并不是说瘦人就不会得脂肪肝。这是由于长期营养物质摄入不足或吸收不良，不能满足机体需求时，便会影响脱辅基蛋白及磷脂的合成，致使脂蛋白生成不足。与此同时，糖皮质类固醇分泌增多，储存脂肪动员增加，大量游离脂肪释放到血液中，超过脂蛋白的转运能力而沉积于肝内，就会引发营养不良性脂肪肝。如有人因患有慢性肠道疾病、长期厌食、节食、偏食、素食、吸收不良综合征及胃肠旁路手术等原因，造成低蛋白血症，缺乏胆碱、氨基酸或趋脂物质。有的女孩子担心发胖，长期素食，或不吃饭，同样也会发生营养不良性脂肪肝。

Fatty liver disease is not an independent is determined by a number of reasons. Increased incidence of fatty liver, and the improvement of people's living standards and dietary changes in the structure has a close relationship. Including nutritional disorders, high alcohol consumption, diabetes, hepatitis, metabolic and endocrine disorders, a number of reasons. Obesity is caused the first cause of fatty liver. The long-term excessive intake of animal fat, vegetable oil, protein and carbohydrates, these foods in the body can not be fully utilized and excess nutrients will be converted into stored fat, leading to obesity, high blood lipids, and fatty liver. Obesity is the number of 5-year doubling of the level of growth. Obese non-alcoholic fatty liver and more sure that the most common risk factors, the incidence rate of 50% -75%, 96% of severe obesity fatty liver can occur. Severe fatty liver in obese children, the incidence rate as high as 80%, 10 "big man" in there 8 is fatty liver.

From alcohol-induced fatty liver disease called nonalcoholic fatty liver, 70% -95% of chronic alcoholics, there are different degrees of fatty liver. Alcohol into the body, in the liver after a series of biochemical processes, eventually turned into a triglyceride. The long-term heavy drinking are bound to have a large number of triglyceride accumulation in the liver among the gradually formed fatty liver. At the same time, the toxicity of alcohol on the liver cells make liver cells to break down fatty acids and metabolic disorder occurs, causing the liver caused by fatty liver fat deposition. The more alcohol, fatty liver are more serious. Daily drinking, more than 5 consecutive years, that is, the risk of fatty liver occur; daily alcohol-induced liver fibrosis and cirrhosis of the danger threshold sector, exceed this threshold sector, liver fibrosis and cirrhosis of the liver can the incidence of increased significantly. A survey pointed out: the 20th century, 60 years of alcoholic cirrhosis and other causes of cirrhosis of the liver compared to 42% in Europe, the Americas 66% Asia 11%,, S Health, S Lord, S version, S right, S Malnutrition can also cause fatty liver. Obesity prone to fatty liver, but not that lean people will not get fatty liver. This is due to the long-term nutrient intake of less than or mal-absorption, the body can not meet demand, will affect the apo-protein and phospholipid synthesis, resulting in lack of lipoprotein generated. At the same time, increased glucocorticoid secretion, storage, mobilization of fat increased, a large number of free fat released into the blood, more than a transit capacity of lipoprotein deposition in the liver, it will lead to malnutrition, fatty liver disease. If a person suffering from chronic intestinal diseases, long-term anorexia, diet, partial eclipse, vegetarian, mal-absorption syndrome, and gastrointestinal bypass surgery and other reasons, resulting in hypoproteinemia, the lack of choline, amino acids or fat material trend. Some girls worry about weight gain, long-term vegetarian, or do not eat the same fatty liver of malnutrition can occur.
