Fatty liver is a pathological state of excessive accumulation of fat in the liver, and the common causes of this disease are: obesity, hyperlipidemia, viral hepatitis, diabetes, alcoholism and so on. Fatty liver can affect the normal physiological function of the liver, interfere with the body’s fat metabolism and energy metabolism, and even lead to the occurrence of cirrhosis in serious cases. In recent years, with the improvement of people’s living standard, the change of diet structure and the development of treatment technology, the modern disease spectrum has changed, and the incidence of this disease has been increasing, which has attracted widespread attention. Clinically, patients with fatty liver often have symptoms such as loss of appetite, nausea, fatigue, pain in the liver area, pressure and fullness in the upper abdomen, etc. A few patients may also develop jaundice, and ultrasound may show the manifestation of fatty liver. According to Chinese medicine, this disease is caused by the loss of drainage of the liver, lack of spleen health, and internal obstruction of phlegm and dampness, and acupuncture has unique therapeutic effects in draining the liver and qi, strengthening the cards and stomach, resolving phlegm and dispelling dampness. Long-term clinical research and a large number of animal experiments have confirmed that acupuncture can lower blood lipids and regulate immune function, so it can effectively prevent and control the occurrence of this disease. Acupuncture stimulates the corresponding acupuncture points, unblocks the meridians, mediates the endocrine and body balance, and treats both the symptoms and the root cause through conditioning, from the inside out. In recent years, we have achieved remarkable efficacy in the treatment of fatty liver with acupuncture. After treatment, patients’ serum cholesterol and triglyceride have been reduced to different degrees, and liver function has been improved without side effects. During the treatment, patients maintain a normal diet, but do not overeat or eat snacks without stopping. Acupuncture therapy has opened up a new way for the treatment of fatty liver that is effective, simple, inexpensive and safe.
