From the Guidelines
Correctable precipitating factors of hepatic encephalopathy include gastrointestinal bleeding, infection, constipation, excessive dietary protein intake, dehydration, electrolyte abnormalities, medication non-compliance, sedative use, and diuretic overuse, and should be addressed promptly to improve morbidity, mortality, and quality of life. Management involves identifying and treating these specific triggers. For gastrointestinal bleeding, endoscopic intervention and blood transfusions may be necessary, as recommended by 1. Infections require appropriate antibiotics based on culture results. Constipation should be treated with lactulose 20-30g (30-45mL) orally 2-4 times daily, titrated to achieve 2-3 soft bowel movements per day, as suggested by 2. Protein intake should be moderated to 1.0-1.5g/kg/day rather than severely restricted. Dehydration requires careful fluid repletion, while electrolyte abnormalities need specific correction (potassium supplementation for hypokalemia). Medication review is essential to identify and discontinue sedatives, benzodiazepines, and opioids, as recommended by 1. Diuretic doses may need adjustment to prevent dehydration and electrolyte imbalances.
Some key points to consider in managing these precipitating factors include:
- Identifying and treating precipitating factors for HE, as recommended by 3
- Using lactulose as the first choice for treatment of episodic overt HE, as suggested by 3
- Considering rifaximin as an effective add-on therapy to lactulose for prevention of overt HE recurrence, as recommended by 4 and 3
- Using oral BCAAs as an alternative or additional agent to treat patients nonresponsive to conventional therapy, as suggested by 3
It is essential to address these correctable precipitating factors to improve patient outcomes, as they can increase ammonia production or decrease ammonia clearance, worsening the neurological symptoms of hepatic encephalopathy in patients with underlying liver dysfunction, as noted by 2 and 1.

- Dehydration 9
- Hypotension 9
- Use of benzodiazepines, psychoactive drugs, and/or alcohol 9
Treatment of Precipitating Factors
Treatment of these precipitating factors is crucial in managing hepatic encephalopathy. This includes:
- Early diagnosis and prompt treatment of infection 5, 9
- Correction of electrolyte imbalance 5, 9
- Laxatives to prevent constipation 9
