Gastrointestinal system bleeding

Cyclooxygenase-1 Inhibitor Chronic (gastrointestinal system) Ulceration/ bleeding in gastrointestinal tract Naproxen29... 

Gastrointestinal system Irritation, inflammation, bleeding, and scarring of the gut wall occur after chronic heavy use of ethanol and may cause absorption defects and exacerbate nutritional deficiencies. 

B. Protamine may be used for reversal of regional anticoagulation in the hemodialysis circuit in cases in which anticoagulation of the patient would be contraindicated (ie, active gastrointestinal or central nenrous system bleeding). 

Ingestion of mercuric salts can cause corrosive ulceration and bleeding with problems in the gastrointestinal system, followed by shock and the collapse of circulatory tract. 

Gastrointestinal system Nausea and vomiting Diarrhea Constipation Anorexia Stomatitis (waste buildup) Bleeding (waste buildup, impaired clotting) Parenteral nutrition (if indicated) Enteral nutrition (if indicated) Dietary restriction of potassium (40 mEq or as ordered), sodium, phosphate based on values of labwork Protein intake based on need (0.6-2 g/kg/day)... 

Prednisolone tablets must be taken after food to prevent any gastrointestinal irritation and bleeding associated with the systemic administration of steroids. 

Portal hypertension most commonly occurs as a consequence of chronic liver disease. Portal hypertension Is caused by Increased blood flow within the portal venous system and increased resistance to portal flow within the liver. Splanchnic blood flow is increased in patients with cirrhosis due to low arteriolar resistance that is mediated by increased circulating vasodilators and decreased vascular sensitivity to vasoconstrictors. Intrahepatic vascular resistance is increased in cirrhosis due to fixed fibrosis within the spaces of Disse and hepatic veins as well as reversible vasoconstriction of hepatic sinusoids and venules. Among the consequences of portal hypertension are ascites, hepatic encephalopathy, and the development of portosystemic collaterals—especially gastric or esophageal varices. Varices can rupture, leading to massive upper gastrointestinal bleeding.
