K_Kidney-Liver connection

Q: What is the K-Kidney-Liver connection in hepatic encephalopathy?

Answer: Exacerbation of hepatic encephalopathy in hypokalemia 

Although all electrolytes need to be managed in hepatic encephalopathy, potassium plays an integral role. Hypokalemia increases kidney ammonia production, which directly exacerbates hepatic encephalopathy.

Other causes of acute exacerbation of hepatic encephalopathy are:

• Gastrointestinal bleeding
• Infection/sepsis 
• Metabolic alkalosis
• Renal insufficiency
• Hypovolemia
• Hypoxia
• Sedative
• Hypoglycemia
• Constipation
• Hepatocellular carcinoma 
• Hepatic vein or portal vein thrombosis
