Peritonitis in patients undergoing peritoneal dialysis is commonly diagnosed based on symptoms of fever, abdominal pain, and nausea, along with lab findings of increased white blood cells over 100 cells/mm3 with neutrophil predominance. Infections are often gram positive or gram negative bacteria but about 20% have no growth on culture. Fungal infections are rare but Candida is the most common cause. Noninfectious complications include GERD, vomiting, electrolyte abnormalities like hypokalemia, and potentially fatal acute mesenteric ischemia.
