Many people look at the “fatty liver” on the physical examination report and wonder why they have fatty liver when they are not fat and eat very green. It is true that fatty liver is common in many people with obesity and metabolic problems, and some of the fatty liver may be related to intake, but fatty liver is not entirely caused by obesity and diet. There are many misunderstandings, today we will sort out: 1, fatty liver is not the same as eating too much fat think that “fatty liver is equal to excessive fat intake” is a common interpretation. In fact, the word “fatty liver” is used to describe the pathological state of liver tissue, the full name is “hepatocellular steatosis”, while the “fatty liver” seen in the ultrasound and CT during physical examination refers to the macroscopic manifestation of diffuse fatty degeneration of the liver. Liver cells are the key site of fat metabolism, so problems in various aspects of fat metabolism in liver cells, such as impairment of fatty acid breakdown and transfer, excessive fat synthesis, poisoning of liver cells and malnutrition, etc., can lead to fat accumulation in liver cells, not just due to excessive fat intake. Therefore, simply eating light does not necessarily solve the problem of fatty liver. We need to realize that fatty liver is far more complicated than it sounds. 2, obesity + fatty liver, the problem may not be simple Obviously obese, especially “belly big” people, if the fatty liver is detected, may not be as simple as eating light. Medical research in recent years that obesity, especially “abdominal obesity”, and a variety of systemic metabolic problems have a very large correlation, not just lifestyle problems. Among non-alcoholics, more than 70% of those with fatty liver are also obese, 75% also have type 2 diabetes, more than half have dyslipidemia, and many have insulin resistance. Obesity and metabolic diseases are likely to be a syndrome of mutual causation, and fatty liver, may be the result of abnormal fat metabolism among them. Therefore, fat people who find fatty liver should also pay attention to their blood sugar, blood lipids and blood pressure for a long time. Of course, whether it is that serious or not, weight loss is very important, just pay attention to weight changes, but also pay attention to the abdominal circumference – abdominal circumference is very large, may be a lot of visceral fat accumulation, and the latter is closely related to a variety of metabolic diseases, cardiovascular disease. 3, fatty liver may also be the result of “alcohol injury to the liver” Some people who often entertain, physical examination detected fatty liver, the first reaction is to pat his stomach and say: “it seems that in the future to eat lighter! In fact, his biggest problem does not necessarily lie in eating, but in drinking. When people drink alcohol, it enters the liver for degradation, and the products of alcohol decomposition have obvious toxicity to liver cells. Early liver damage may be manifested as alcoholic fatty liver, commonly known as “alcoholic liver”. Both chronic alcohol abuse and short-term binge drinking can be harmful in this way. Sustained alcohol damage can also lead to alcoholic hepatitis, cirrhosis, abnormal liver function, and a significantly higher risk of liver cancer than in the general population. For people who drink a lot of alcohol and develop a fatty liver, it is necessary to stop drinking and seek medical attention. 4. Drug side effects and hepatitis can also lead to fatty liver. Since poisoning and damage to liver cells can lead to fatty liver, can other factors that damage the liver do the same? It is entirely possible. It is relatively clear that some drugs with liver side effects may cause fatty liver when taken for a long time, such as the common hormone drugs, and the anti-arrhythmic drug amiodarone. Therefore, if you have to use such drugs for a long time, your doctor will advise you to review your liver function regularly and adjust your drug regimen if there are any abnormalities. In addition, viral hepatitis, especially hepatitis C, may also manifest as fatty liver in the early stages. 5, very thin people may get fatty liver instead There are some people who are not fat, do not drink, do not take medication, do not have hepatitis, and also eat very little very light, but also found fatty liver, and this is why? Because the liver does not only synthesize and break down fat, but also has a reserve function. When the liver encounters “starvation”, it thinks that the body has entered a state of “famine”, so it starts “war mobilization” and reserves a large amount of fat, reducing the breakdown of fat and transport out, in order to prepare for emergencies. Therefore, for people who are chronically malnourished, over dieting to lose weight, etc., fatty liver may also appear. Therefore, it is important to lose weight in a scientific and reasonable way, and not to disregard the dietary balance by giving up the necessary energy intake just because of weight loss.
