Gastrointestinal stasis is mostly seen in right heart failure due to various cardiovascular diseases and portal hypertension due to various causes. It can be seen in various causes of portal hypertension, the blood in the portal vein must be driven by a certain pressure to continuously flow to the liver, the normal portal pressure is 13-24cmH2O, the average is 18cmH2O. if the portal blood flow is obstructed and the blood is stagnant for various reasons, the pressure in the portal system will exceed the normal value, and a series of symptoms will appear, manifested as splenomegaly and splenic function hyperplasia, esophagogastric fundic varices and vomiting of blood and ascites, which is called portal hypertension. In adults, the portal vein is an important vessel formed by the convergence of the splenic vein and the superior mesenteric vein behind the pancreas. Blood from abdominal organs such as the stomach, small intestine, spleen, pancreas and colorectum must pass through the portal vein before it can flow to the liver, where nutrients absorbed by the digestive tract can be synthesized into various substances necessary for human survival, and where many toxins and waste products produced by the body can be metabolized and detoxified. Gastrointestinal venous blood does not flow smoothly through the portal vein to the liver, resulting in gastrointestinal stasis. Clinical symptoms include lack of appetite, nausea and vomiting, often accompanied by hepatosplenomegaly. The early stage of this disease can be asymptomatic, but once symptoms appear, it is often more dangerous. Therefore, it is necessary to follow up patients with post-hepatitis cirrhosis and schistosomiasis cirrhosis regularly with health checkups for early detection and early treatment. Prevention of gastrointestinal stasis must ensure normal rest, it is best not to often stay up late at work to avoid burdening the body general physical activity can increase energy consumption, which is very beneficial to health. And regular physical exercise can have an important therapeutic effect, lowering blood pressure and improving glucose metabolism. Therefore, it is recommended that appropriate physical activity of about 30 minutes a day should be carried out.
