Hepatic Encephalopathy: A Comprehensive Guide for Patients and Caregivers

At a Glance

Hepatic Encephalopathy (HE) is a decline in brain function caused by severe liver disease. When the damaged liver cannot filter toxins like ammonia, they build up in the bloodstream. Standard treatments like lactulose and rifaximin clear ammonia, and patients may need liver transplant evaluation.

When you or a loved one are diagnosed with Hepatic Encephalopathy (HE), it is normal to feel overwhelmed by the sudden changes in cognitive function, memory, and behavior. HE is a decline in brain function that occurs as a result of severe liver disease. In this condition, the liver cannot adequately remove toxins from the blood. This causes a buildup of toxins, particularly ammonia, in the bloodstream, which can lead to brain dysfunction.

This guide is designed to help you and your care team navigate the complexities of this diagnosis. The information provided here will empower you to understand the disease, recognize the symptoms early, and actively participate in the treatment plan.

Common questions in this guide

What causes Hepatic Encephalopathy?
Hepatic Encephalopathy is caused by severe liver disease. When the liver is too damaged to effectively filter toxins like ammonia from the blood, these toxins build up and affect brain function.
What triggers a Hepatic Encephalopathy flare-up?
Common triggers that can cause an HE flare-up include infections, constipation, and dehydration. Working with your care team to avoid these triggers is a critical part of managing the condition.
How is Hepatic Encephalopathy diagnosed?
Doctors primarily diagnose HE based on a clinical evaluation of your physical symptoms and specialized cognitive tests. They do not rely solely on ammonia blood levels to confirm a diagnosis.
What are the standard treatments for Hepatic Encephalopathy?
The standard treatments for HE include medications such as lactulose and rifaximin. These medications work by helping your body clear excess ammonia, which reduces brain dysfunction.
Will I need a liver transplant if I have Hepatic Encephalopathy?
Because HE is an indicator of advanced liver disease, your doctor may recommend beginning the evaluation process for a liver transplant as part of your long-term management plan.

Questions to Ask Your Doctor

Curated prompts to bring to your next appointment.

  1. 1.Who should be the primary point of contact on my care team if I notice signs of a hepatic encephalopathy flare-up at home?
  2. 2.Are there specific dietitians or physical therapists specializing in liver disease that you recommend to help me maintain my muscle mass?
  3. 3.At what point in my disease progression should we formally begin the evaluation process for a liver transplant?
