Erroneous understanding of fatty liver
In the crowd around us, the patients with fatty liver are not uncommon. Clinical epidemiological investigation showed that with people’s lives, habits and diet changes, and clinical B-technological progress and wide application of the detection rate of fatty liver in recent years, the increasing incidence of the rise. In some areas, fatty liver has become the second largest after the viral liver disease.
Fatty liver is caused by various liver fat metabolism disorders, lipid disorders of homeostasis, resulting in liver cells is mainly triglyceride accumulation of excess fat as a pathological state. Although fatty liver is common, but relatively little attention in the past, understanding there may be some bias. Some people think that fatty liver prognosis is good, in health does not matter, its lightly. Some people will talk about “fat (fatty liver)” discoloration, in the medical examination discovered mental stress, anxiety Huang Huang, and even family members worried about infection. Indeed, the prognosis of fatty liver is not all good, it was reported that severe obesity in patients with fatty liver, approximately 1 / 4 of complications in liver fibrosis, 1.5% -8% of concurrent liver cirrhosis, non-alcoholic fatty liver disease is now recognized as for a common cause of cryptogenic cirrhosis of the liver. However, fatty liver is different from viral hepatitis, it is not contagious, through the life-changing habits and a positive exercise, etc., may effectively prevent, self-care and with drug therapy may be better to promote health restoration.
Fatty liver caused by many reasons, one will be obese. Liver B-census found that about 50% of obese patients may be complicated by fatty liver. Some people though body weight did not reach the standard of obesity, but if a marked increase in abdominal subcutaneous fat, but also prone to fatty liver. In addition, weight loss if the weight of smaller, decreased by 5 kg per month would be the mobilization of adipose tissue free fatty acids into the liver, thereby stimulating a large number of insulin secretion, but also easily lead to fatty liver and steatohepatitis. 2 for the malnutrition. By the human body caused by a chronic lack of energy and protein present in our country have been rare. 3 for drinking. Alcohol and its metabolites on liver cell damage of both can cause their fat and metabolic disorders; and chronic alcoholism can cause malnutrition, these factors led to the formation of fatty liver. According to statistics, the daily drinking 80-120 grams (about 50 degrees half a catty white wine), or eight bottles of beer, for 10 years, 90% of the fatty liver will occur. 4 for chemical poisons or drugs damage. The liver is the body’s detoxification and drug metabolism of an important organ, volatile organic compounds via the skin, gastrointestinal or respiratory tract into the body and lead to liver damage, certain medications may also be induced fatty liver. Five of diabetes. Fatty liver that is primarily non-insulin-dependent type II diabetes are closely linked. 6 for hyperlipidemia. Various types of hyperlipoproteinemia can cause fatty liver, but the closest hypertriglyceridemia. In addition, high blood pressure, genetic and social factors on the incidence of fatty liver also have an impact.
Higher classification of fatty liver. According to the different causes, is divided into alcoholic and non-alcoholic fatty liver disease: According to the length of the course is divided into acute and chronic fatty liver; according to pathological changes of liver tissue was divided into simple fatty liver (including large and small bubble-type foam type of fatty liver), steatohepatitis and fatty liver cirrhosis. Vesicles with acute-type and fatty cirrhosis serious condition, the prognosis is poor. In addition, the prognosis of fatty liver is still depends on whether the elimination of the cause, such as the cessation of alcohol and toxic exposure, as well as a merger of the hepatitis or cardio-cerebral vascular diseases.
Clinically, the majority of patients with fatty liver do not have abnormal liver function, and no obviously specific symptoms, some may simply feel Youlei discomfort and chest and abdominal fullness and so on. Some patients may be anorexia, nausea, disgust oil, vomiting, fatigue, abdominal distension, pain and other liver condition, physical examination found mild hepatosplenomegaly and elevated serum transaminases, a few even jaundice. If the development of cirrhosis of the liver may appear soft-limb weakness, abdominal swelling, bleeding, or melena. Diagnosis of B-ultrasonography or CT, etc. rely on imaging examination, in addition can be combined index of serum liver function tests, such as ALT activity and glutathione S-transferase activity and so on.
