Chronic fatty liver is more common, with a slow, insidious onset and a long course. In the early stage, there are no obvious clinical symptoms, which are usually discovered by chance during ultrasound. Some patients may present with loss of appetite, nausea, fatigue, pain in the liver area, abdominal distension, and a feeling of distention and pressure in the right upper abdomen. Since these symptoms are also non-specific and similar to general chronic gastritis and cholecystitis, they are often easily misdiagnosed and missed. The main causes of fatty liver are: 1, long-term alcoholism 2, overnutrition 3, malnutrition 4, chronic diseases such as diabetes, hepatitis, hyperthyroidism, severe anemia 5, drug-related liver damage 6, hyperlipidemia/hypercholesterolemia, of which hypertriglyceridemia is the most closely related, most often accompanied by obesity, diabetes and alcoholism 7, other such as pregnancy, genetic or mental, psychological and social factors, certain Industrial toxins, etc. Among them, alcohol is the main culprit. Fatty liver can develop into liver cirrhosis and liver cancer. Nearly 60% of chronic alcoholics develop fatty liver, and 20% to 30% will eventually develop cirrhosis. About 1.5% to 8% of patients with non-alcoholic fatty liver can progress to cirrhosis. About 2-3% of chronic alcoholics develop liver cancer through alcoholic cirrhosis. Non-alcoholic fatty liver rarely develops liver cancer because of the low incidence of cirrhosis and its late appearance. Treatment and precautions 1. strictly prohibit alcohol 2. three meals a day should be regular and quantitative, to achieve 7 to 80% full; dinner should be eaten less, do not add meals before going to bed; avoid overeating. Steam, braised, stewed, stewed cooking method is appropriate, less fried, fried, fried in oil. After eating fruit to reduce the amount of staple food, day eat an apple, you should reduce the staple food one or two. 3, limit or forbid the consumption of animal offal (such as animal heart, liver, brain, intestines, stomach, fish roe, etc.), animal oil soup, animal head (such as fish head, etc.), limit or forbid the consumption of sweets, egg yolk, chocolate, fatty meat, chicken skin and other foods. Avoid using animal oil. 4, fatty liver patients can often choose to eat oats, corn, seaweed, nori, garlic, apples, fat-free milk or yogurt, onions, sugar cane, carrots, hawthorn, fungus, winter melon and other foods with lipid-lowering effects. 5.Frequent exercise such as running, etc. 6, weight loss and weight control is worth noting that the weight should not be dropped suddenly, such as sudden weight loss (5 kg in a month), also prone to fatty liver and make the condition of patients with existing fatty liver further aggravated. 7.Actively treat the primary disease and remove the cause. 8.Patients with abnormal liver function can be treated with reasonable medication. 9.B ultrasound is the preferred diagnostic method, and it is recommended that people above middle age or those at high risk of fatty liver (such as long-term alcohol consumption, obesity, etc.) should be regularly screened by ultrasound.
