Gastrointestinal stasis is most commonly seen in right heart failure due to various cardiovascular diseases and in portal hypertension due to various causes. Gastrointestinal stasis can be seen in various causes of portal hypertension, where gastrointestinal venous blood does not pass smoothly through the portal vein to the liver, resulting in gastrointestinal stasis. It can be seen in various causes of portal hypertension, where the venous blood of the gastrointestinal tract does not flow smoothly through the portal vein to the liver, thus causing gastrointestinal stasis. Venous reflux disorders at any site can cause esophageal varices, the latter being an important complication of portal hypertension because of the formation of collateral circulation between the portal vein and superior vena cava in portal hypertension. The specific lateral circulation pathways are as follows: portal vein – gastric coronary vein – esophageal venous plexus – odd vein – superior vena cava. Clinical symptoms such as lack of appetite, nausea and vomiting are often associated with hepatosplenomegaly. To prevent and treat gastrointestinal stasis, the following points should be noted: 1. Do not eat solid food or drink milk. 2. Drink at least 1 liter of plain water (no sugar added) more often every day. 3. If you have too much diarrhea, drink light salt water (half a teaspoon of table salt in 1 liter of water) to replenish the water lost due to diarrhea. 4. If you find red or colorless snot-like mucus in the stool, go to the pharmacy and buy some digestive aids to eat. Do not eat too much at each meal. If the attacks are frequent and getting worse, go to a regular hospital to see a doctor.
