After overeating, liver pain is considered to be related to cholecystitis, fatty liver, hepatitis and other diseases, which need to be further examined in the hospital to clarify the cause of the disease, and then dealt with in a timely manner. 1. Cholecystitis: usually due to the acute attack of cholecystitis after overeating, irritating the mucous membrane of the gallbladder, thus causing constant pain in the liver, cholecystitis may have severe pain in the right upper abdomen or colic and other symptoms. 2. Fatty liver: it is usually due to the fact that after overeating, a large amount of fat enters the liver, which increases the burden of the liver, causing the liver to swell and the tension of the hepatic peritoneum to rise, which leads to the phenomenon of constant pain in the liver area after overeating and fatigue, nausea and other symptoms. 3. Hepatitis: It may be due to the fact that after overeating, a large amount of food and alcohol need to be metabolized and decomposed in the liver, increasing the burden on the liver. If you are a patient with hepatitis, overeating may cause hepatitis to worsen and can lead to liver damage, which can cause the phenomenon of constant pain in the liver area after overeating. Hepatitis usually results in symptoms such as loss of appetite and aversion to greasy food. If there is pain in the liver after overeating, you should go to the hospital in time to avoid delaying your condition, and you should have a reasonable diet, balanced nutrition and rest in your daily life.
