BRAIN DYSFUNCTION DUE TO LIVER DISEASE
Hepatic Encephalopathy
A reversible brain dysfunction in patients with advanced liver disease, causing confusion, behavioural changes, drowsiness and risk of coma. Managed urgently with specific laxative therapy and trigger control.
ABOUT THIS CONDITION
What is Hepatic Encephalopathy
Hepatic encephalopathy is a brain dysfunction that develops in patients with advanced liver disease, particularly cirrhosis. It occurs when the failing liver is unable to clear toxic substances — particularly ammonia — from the blood, allowing them to reach and affect the brain. Typical features range from subtle changes such as poor concentration, sleep disturbance and personality changes (minimal or covert encephalopathy) to overt symptoms including confusion, disorientation, slurred speech, drowsiness, abnormal movements (such as flapping tremor of the hands) and, in severe cases, coma. Common triggers include infections, gastrointestinal bleeding, constipation, dehydration, electrolyte imbalances, certain medications, high protein intake and worsening liver function. Hepatic encephalopathy is reversible if treated promptly — by identifying and treating triggers and giving specific laxative therapy that reduces ammonia absorption from the gut. Dr. Patnam Pravallika Reddy provides urgent evaluation, inpatient care and long-term management at Lux Hospitals, Hyderabad.

HOW WE TREAT IT
Treatment Approach
Trigger Control with Specific Laxative Therapy
The most effective approach is urgent identification and treatment of triggers — infections, bleeding, constipation and electrolyte imbalances — combined with specific laxative therapy that reduces ammonia absorption from the gut. Severe cases need hospital admission and intensive care.
- 1
Consultation & Assessment
Dr. Pravallika reviews the patient's mental state and liver disease history, examines for triggers and arranges blood tests, imaging and other investigations.
- 2
Treatment Planning
An urgent plan is created to identify and treat triggers, start specific laxative therapy and provide supportive care.
- 3
Medical Management
Trigger control, specific laxative therapy, supportive care, treatment of infections and management of any bleeding or electrolyte imbalances.
- 4
Recovery & Follow-up
Long-term follow-up with maintenance laxative therapy, monitoring of liver function and trigger avoidance to prevent recurrence.
AVAILABLE TREATMENTS
Treatment Options
Identifying and Treating Triggers
Searching for and treating triggers such as infections, gastrointestinal bleeding, constipation, dehydration and electrolyte imbalances is essential.
Specific Laxative Therapy
Specific laxative therapy that traps and reduces ammonia absorption from the gut is the mainstay of treatment, given regularly to titrate to a few soft stools a day.
Adjunct Antibiotic Therapy in Selected Cases
Adjunct gut-acting antibiotic therapy is added in selected patients to reduce ammonia-producing gut bacteria.
Supportive Care and ICU Monitoring
Hospital admission, supportive care and ICU monitoring are needed for severe encephalopathy and coma.
Long-Term Maintenance and Trigger Avoidance
Long-term maintenance laxative therapy and structured trigger avoidance significantly reduce the risk of recurrent episodes.
