Liver disease will first affect the digestive and absorption functions of the spleen and stomach, poor spleen and stomach, nausea, aversion to grease are symptoms of the digestive tract, the following points can be examined to confirm the diagnosis: 1, gastric acid and digestive enzyme secretion is reduced: hepatitis patients often have a decrease in gastric acid, digestive enzymes (especially pancreatic enzymes) production and secretion of reduced activity, resulting in digestive and absorption functions are affected. 2, bile secretion, excretion disorders: the acute phase of hepatitis and jaundice hepatitis is mostly accompanied by capillary bile duct inflammation and obstruction, resulting in insufficient secretion and excretion of bile, affecting the absorption of lipids and fat-soluble vitamins. 3, gastrointestinal inflammation: the acute phase of viral hepatitis is often accompanied by gastroenteritis, resulting in inflammatory changes such as bleeding in the stomach and duodenum and jejunum, lymphocyte infiltration and submucosal edema, resulting in gastrointestinal digestion and absorption dysfunction. 4, increased portal vein pressure: chronic active hepatitis patients, due to extensive fragmentation of liver parenchyma necrosis muscle fiber tissue proliferation, active septum formation can appear portal hypertension, followed by gastrointestinal stasis, edema, affecting the digestion and absorption of food. 5, extra-hepatic organ inflammation: such as hepatitis combined with biliary ductitis and pancreatic inflammation, can appear the above symptoms.
