Hepatic Encephalopathy: What to Do When Confusion Returns or Treatment Is Not Working Well Enough

TL;DR

• New or suddenly worse confusion with cirrhosis needs prompt medical assessment. Severe confusion, slurred speech, marked sleepiness, vomiting blood, or black stools can require emergency care.
• Hepatic encephalopathy can return even when treatment is being taken. Infection, bleeding, constipation, dehydration, electrolyte changes, and some medicines can trigger an episode.
• Lactulose is first-line therapy for overt hepatic encephalopathy. Clinicians commonly adjust it toward 2–3 soft bowel movements a day; excessive diarrhea can cause dehydration and create another problem.
• Rifaximin is commonly added when overt episodes recur. If confusion keeps returning, the liver team may need to review triggers, medicines, difficulties taking treatment, other causes of confusion, and the wider cirrhosis plan.
• People using mama health often describe someone close to them noticing subtle changes first, lactulose urgency disrupting daily life, and recurring confusion reducing confidence around work, travel, and independence.

What is hepatic encephalopathy, and why can confusion return?

Hepatic encephalopathy (HE) is a change in brain function linked to severe liver dysfunction or blood bypassing the liver, and it can range from subtle thinking changes to profound confusion or coma.

With decompensated cirrhosis, HE may affect attention, memory, sleep, speech, behavior, coordination, and alertness. Asterixis — a brief “flapping” loss of hand posture — can occur, but it is not present in every episode and is not unique to HE.

An episode can improve and later return. That does not automatically mean the prescribed treatment has “failed.” A new trigger may have appeared, a medicine may be difficult to take consistently, or the confusion may have another cause that needs assessment.

For more context on how HE fits alongside ascites, gastrointestinal bleeding, jaundice, and other complications, mama health has a guide to the complications of decompensated cirrhosis.

What should you do if confusion suddenly returns?

Sudden confusion should be assessed promptly because HE is only one possible cause of altered thinking, and some alternatives are emergencies.

If someone with cirrhosis becomes suddenly confused, has slurred speech, is very difficult to wake, cannot stay safe, vomits blood, or passes black or tarry stools, seek emergency medical care. Do not drive during an episode of confusion or marked sleepiness.

If the change is milder but clearly new, contact the liver care team promptly. It can be useful to record when the change started, whether sleep or behavior changed first, recent bowel movements, any missed or changed medicines, fever or infection symptoms, vomiting or diarrhea, reduced fluid intake, constipation, and possible signs of bleeding.

Do not increase, stop, or restart HE medicines based only on an app, an ammonia result, or a general article. Medication changes belong with the prescribing clinician.

What can make hepatic encephalopathy break through treatment?

Breakthrough HE is often associated with a precipitating factor, so a clinical review usually looks for what changed around the time confusion returned.

Common factors include infection, gastrointestinal bleeding, constipation, dehydration, electrolyte disturbances, kidney problems, and medicines that can worsen sedation or mental status. A recent hospital stay, vomiting, diarrhea, reduced intake, or changes to diuretics may also be relevant.

This is why “the treatment stopped working” may not tell the whole story. The same lactulose or rifaximin regimen may have been adequate until another problem altered the balance.

Fluid decisions can be especially complicated in advanced cirrhosis because both dehydration and fluid overload can matter. mama health’s guide to fluid intake with decompensated cirrhosis explains why there is no single water target that fits everyone.

What if lactulose is difficult to live with?

Lactulose can be effective and still be difficult to fit into everyday life because urgency, loose stools, bloating, and cramping can interfere with work, travel, sleep, and social plans.

Lactulose is the usual first-line medicine for overt HE. Clinicians commonly adjust it toward about 2–3 soft bowel movements a day. More bowel movements are not necessarily better. Excessive diarrhea can contribute to dehydration, which can itself increase the risk of another episode.

In the mama health app, people living with decompensated cirrhosis often describe planning their day around toilet access or worrying about taking lactulose before leaving home. Some describe shifting or missing doses because of urgency. These experiences do not show what anyone else should do, but they reveal an important issue to discuss openly: when a medicine is too disruptive to take as prescribed, the prescribing clinician needs to know what is getting in the way.

Details such as when urgency happens, how often stools are loose, whether constipation occurs on other days, whether doses are difficult to take, and how the schedule affects sleep or leaving the house can make that discussion more specific.

What if lactulose and rifaximin still do not feel like enough?

If overt HE keeps returning despite the prescribed regimen, a structured clinical review can help clarify why rather than simply assuming that a higher dose or another medicine is needed.

Rifaximin is commonly used as an add-on to lactulose to reduce recurrence of overt HE. In a major randomized trial of recurrent HE, most participants were also receiving lactulose, and rifaximin reduced both breakthrough HE episodes and HE-related hospitalizations over six months.

Persistent or recurrent confusion still requires a wider assessment. The liver team may consider whether there is an untreated trigger, whether medicines are being taken as intended, whether side effects make the regimen difficult to follow, whether another medicine is contributing to sedation, and whether the symptoms could have another neurological or medical cause.

Repeated or difficult-to-control overt HE can also lead to a broader discussion about the severity of liver disease. For some people, that may include whether liver transplant evaluation is appropriate. That decision depends on the full medical picture and belongs with a specialist team.

Does an ammonia level show whether hepatic encephalopathy is getting worse?

No. An ammonia level alone does not diagnose HE, grade its severity, or show whether treatment is working well enough.

Ammonia is involved in the biology of HE, but blood levels do not reliably match the degree of confusion in an individual person. Liver guidance therefore emphasizes clinical assessment and consideration of other causes of altered mental status.

This distinction matters when confusion returns. A high ammonia result does not replace an assessment of symptoms, possible triggers, medicines, and other medical problems. Treatment decisions should not be based on that number alone.

Should protein be reduced when hepatic encephalopathy returns?

No routine long-term protein restriction is recommended for cirrhosis with HE.

Older advice sometimes encouraged cutting protein to reduce ammonia production. Current liver guidance instead emphasizes adequate nutrition because malnutrition and loss of muscle are common in advanced cirrhosis. General guideline targets are often around 1.2–1.5 g of protein per kg of body weight per day, although an individual target should come from a liver specialist or dietitian who knows the full medical history.

If eating becomes difficult, appetite changes, or a particular food pattern seems connected with symptoms, that information can be brought to the clinical team rather than making a major restriction without guidance.

What do people using mama health describe when HE keeps returning?

People using mama health often describe HE as particularly difficult because the person experiencing it may not be the first to realize that something has changed.

A partner, relative, or caregiver may notice a sentence that no longer makes sense, unusual sleepiness, irritability, a forgotten routine, slowed responses, or a change in speech. This reflects an important feature of HE: changes in thinking and awareness can make outside observations especially useful.

Other recurring themes in the app include the practical burden of lactulose urgency, fear about being alone during another episode, reduced confidence around driving or work, and uncertainty after a hospital discharge when medicine changes or follow-up plans are not fully understood.

These are experience-based themes, not prevalence estimates or clinical evidence. Their value is practical. They can bring attention to aspects of daily life that are easy to miss during a short medical appointment.

What information is useful to bring to the next liver appointment?

A short timeline of what changed can make the appointment more focused and easier to follow.

Useful information can include when confusion, sleep changes, speech changes, or unusual behavior appeared; bowel movement frequency and consistency; lactulose or rifaximin doses that were delayed or difficult to take; new prescriptions, over-the-counter products, or sleep medicines; possible infection symptoms; vomiting, diarrhea, constipation, or reduced intake; signs of gastrointestinal bleeding; recent emergency visits or hospital stays; and how the episode affected work, driving, daily tasks, or time alone.

It can also be useful to record what the person who first noticed the change observed. The aim is not to work out the diagnosis at home. It is to give the clinician a clearer picture of what happened between appointments.

How can mama health support you between appointments?

mama health is a free app for everything your condition asks of you, grounded in medical science and the experience of others, so you do not have to figure it out alone.

• Ask anything. Answers are shaped by trusted sources, your history, and thousands like you.
• Find specialists and care near you, wherever you are.
• Understand your information. Get educational explanations of your labs, prescriptions, and reports alongside the history you have shared, so you can better understand what you are looking at and prepare questions for your doctor.
• Track for reflection. Record the symptoms, bowel patterns, medicines, appointments, and questions you choose to track. These notes can be turned into a structured report you can take to your doctor’s appointment.

mama health does not diagnose HE, determine whether a medicine is working, or tell you how to change treatment.

What is the bottom line when confusion returns?

When confusion returns with cirrhosis, the priority is prompt medical assessment and understanding what changed, rather than simply assuming the usual treatment has stopped working.

HE can recur alongside infection, bleeding, constipation, dehydration, medication effects, or other medical problems. Lactulose and rifaximin are established therapies, but side effects and everyday routines can make consistent use difficult. A clear record of symptoms, bowel patterns, medicine challenges, possible triggers, and what a caregiver noticed can make the next clinical discussion more useful.
