Portal hypertension drives splanchnic vasodilation, the kidney reads effective hypovolemia and retains sodium, and from that single mismatch flow ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, and hepatic encephalopathy. The episode anchors ascites on the serum-ascites albumin gradient and the fixed spironolactone-to-furosemide ratio, then moves through the TIPS-versus-paracentesis decision, hyponatremia thresholds, the peritonitis antibiotic-plus-albumin bundle, terlipressin for hepatorenal syndrome, and lactulose plus rifaximin for encephalopathy. Every threshold is mechanism-derived rather than arbitrary.\n \nTopics covered\n\nOne physiology, four complications\nAscites and the serum-ascites albumin gradient\nDiuretic management and the spironolactone-furosemide ratio\nLarge-volume paracentesis and albumin replacement\nRefractory ascites: TIPS versus serial paracentesis\nHyponatremia thresholds\nSpontaneous bacterial peritonitis bundle\nHepatorenal syndrome and terlipressin\nHepatic encephalopathy: lactulose plus rifaximin\n \n \nKey decisions\n\nA serum-ascites albumin gradient over one point one supports portal hypertension while a gradient under one point one points toward carcinomatosis, tuberculous, or pancreatic ascites; low ascitic protein under two and a half fits cirrhotic ascites while high protein with a high gradient suggests heart failure or constrictive pericarditis.\nThe diuretic backbone is spironolactone plus furosemide in a fixed hundred-to-forty ratio, starting at a hundred plus forty and maxing at four hundred plus one hundred sixty, and large-volume paracentesis above five liters needs albumin at six to eight grams per liter removed.\nAn ascitic neutrophil count over two hundred fifty diagnoses spontaneous bacterial peritonitis; treat empirically with a third-generation...","thumbnail_url":"https://img.transistorcdn.com/-FuAdDBcPDLhEoUmroZKtOBRvuBn_FHPpYlh41hOnU4/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9iNzlh/ZTU4Y2MzNWExMjQ5/MjA5OWMwMmI3ZTk5/NGFiZS5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
