21世纪是脂肪肝挑战人类的世纪。国内调查,脂肪肝的人群患病率为3.2％～11.4％,其中以中老年人为多。 脂肪肝的危害,一是可以引起脂肪性肝炎;二是脂肪肝进一步发展可导致肝硬化、肝衰竭乃至死亡。 目前治疗脂肪肝尚无特效药物,故预防脂肪肝就显得格外重要了。近年来在预防脂肪肝方面有了许多新认识,现简述如下: 第一,戒酒或限制饮酒量,这在中老年人尤为重要。我国调查脂肪肝病例时发现,过量饮酒并持续时间较长,是引起脂肪肝的重要原因,约占所有脂肪肝的三分之二。在每天饮酒精160克人中,40％有脂肪肝。一般认为,酒精量每天超过80克,就可造成肝损害。80克酒精相当于38度白酒220毫升(约合4市两多一点)所含的酒精。如果人们限制酒精摄入,至少使人群中脂肪肝减少60％。
The 21st century is the century that fatty liver challenges humanity. Domestic survey, the prevalence of fatty liver was 3.2% to 11.4%, of which more than the elderly. Fatty liver harm, one can cause steatohepatitis; two is the further development of fatty liver can lead to cirrhosis, liver failure and even death. Currently there is no specific treatment of fatty liver medicine, it is particularly important to prevent fatty liver. In recent years, there have been many new understandings in preventing fatty liver. These are summarized as follows: First, it is especially important for middle-aged and elderly people to abstain from alcohol or restrict alcohol consumption. China’s investigation of cases of fatty liver found that excessive drinking and duration of longer, is an important cause of fatty liver, accounting for about two-thirds of all fatty liver. In drinking 160 grams of alcohol daily, 40% have fatty liver. Generally believed that the amount of alcohol more than 80 grams per day, can cause liver damage. 80 grams of alcohol equivalent to 38 degrees white wine 220 ml (about 4 more than two cities) contains alcohol. If people limit their alcohol intake, they should at least cut their fatty liver by 60%.
