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. Patients with gastrointestinal stasis should be careful not to eat solid foods and not to drink milk. At least 1 liter of plain water (no sugar) should be drunk more often every day. If the diarrhea is too frequent, drink light salt water (half a teaspoon of table salt in 1 liter of water) to replace the water lost due to diarrhea. If you find red or colorless snot-like mucus in the stool, go to the pharmacy and buy some digestive aids to take. 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.
