Sleeping all day and awake all night: sleep reversal in liver disease | CION Cancer Clinics
Sleeping through the day and staying awake at night is often an early sign that a weak liver is affecting the brain. It can also come from itching, fluid, pain, medicines or worry. It is usually treatable once the cause is found. This page explains the common causes, what the family can do at home, why sleeping tablets can be dangerous, and when drowsiness needs hospital today. At CION Cancer Clinics, our team supports patients and families through symptoms, follow-up and life during and after treatment.

The short answer
Why does someone with liver disease sleep all day and stay awake all night?
Sleeping through the day and lying awake at night is one of the earliest signs that a weak liver is starting to affect the brain. Doctors call this a reversed sleep pattern, and it is often the first change of hepatic encephalopathy. It is treatable, and the sleep pattern usually improves once the cause is dealt with.
It is not always the liver
Many ordinary things also break up sleep in someone with liver cancer or cirrhosis: itching that is worse at night, a swollen belly that makes lying flat uncomfortable, water tablets that send them to the toilet, pain, or plain worry. Several of these can be present together. The treating team needs to sort out which ones are at work.
Why families should mention it
Families often treat it as a nuisance and buy a sleeping tablet from the chemist. In liver disease that can make things much worse. A change in the sleep pattern is worth reporting to the doctor in the same way you would report a fever or new swelling. The wider picture of early changes is on our page about the early signs families notice first.
A new sleep pattern is a symptom to report, not a habit to correct by force.The usual causes
What else can turn sleep upside down in liver disease?
The doctor will think about all of these. You can help by noticing which ones fit.
Early encephalopathy
Waste products that a healthy liver clears reach the brain and upset the body clock. Look for other small changes alongside it: irritability, forgetfulness, slower answers or shaky handwriting.
Discomfort at night
- Itching from jaundice, often worse in bed
- A tight belly from fluid (ascites)
- Pain under the right ribs
- Breathlessness when lying flat
Medicines and timing
Water tablets taken late in the day, steroids, some painkillers and some cancer medicines can all disturb sleep. Sometimes the fix is simply changing the time a tablet is taken, which only the doctor should decide.
Mood and worry
Fear about the illness, low mood and long empty days in bed all weaken night-time sleep. These are real, common and treatable, and they deserve a conversation of their own.

When sleepiness means hospital today
Go to hospital today if the person is so drowsy you cannot wake them properly, does not recognise you, is talking nonsense, has a fever, is vomiting blood or passing black stools, or has a painful, tight belly with fever. Sleepiness that is getting deeper by the hour is an emergency, not tiredness. Do not give sleeping tablets or calming medicines at home. Tell the emergency doctor about the liver disease and bring every medicine they take. See when confusion needs hospital admission.
What helps at home
What can the family do to help night-time sleep?
Keep the bowels moving
Constipation is one of the most common triggers. Give lactulose exactly as the doctor advised and tell the team if stools become hard or stop.
Make the day a day
Open curtains in the morning, sit them up for meals, and keep short naps rather than long afternoon sleeps. Gentle activity in daylight helps the body clock.
Give a late evening snack
People with cirrhosis go without food for a long stretch overnight. A small snack at bedtime, agreed with the team, helps protect muscle and energy.
Write it down and call the team
Note sleep times, bowel habits and any new behaviour for a few days. Share it with the oncologist or liver doctor at the next call, or sooner if it is getting worse.

Commonly believed
Four things families tell us about sleep, and what is true
"He is just lazy now, or he has given up."
A reversed sleep pattern in liver disease is often a medical change in the brain, not a choice. Treating the cause usually brings back a more normal rhythm. Arguing with him rarely helps.
"A sleeping tablet at night will fix it."
Many sleeping tablets and calming medicines are cleared by the liver and can tip a person into deeper confusion. Never start one without the treating doctor's agreement, even a mild one from the chemist.
"Less protein will clear his head."
This old advice has changed. Most people with cirrhosis need enough protein to keep their strength. Read should protein be reduced before changing the diet.
"Loose stools mean the lactulose is too strong, so stop it."
Soft stools are usually the aim. Too many, or watery stools with weakness, need a call to the team to adjust it, not a sudden stop. See lactulose explained.
Being straight with you
What this page cannot tell you
It cannot tell you why the person you care for is sleeping this way. A reversed sleep pattern can come from the liver, from medicines, from pain or itching, from low mood, or from several of these at once. Only a doctor who examines them, checks the blood and reviews every tablet can sort that out.
It cannot change any medicine
Lactulose, rifaximin, water tablets and painkillers are adjusted by the treating team. At CION, the medical oncologist and supportive care team review symptoms like this. Hepatology care and any hospital admission are coordinated through accredited partner hospitals and liver specialists when needed.
Who this does not apply to
This page is about adults with cirrhosis, liver cancer or cancer that has spread to the liver. It does not apply to someone with no liver disease, to shift workers, or to children. Sudden weakness of one side, a drooping face or slurred speech is a possible stroke and needs emergency care straight away.
If you are unsure whether the change in sleep is serious, call the helpline and describe it. Someone will help you decide how soon they should be seen.Questions we are asked
Common questions about sleep and liver disease
Is day and night reversal a sign of liver failure?
It can be an early sign that the liver is not clearing waste well enough and the brain is affected. It does not on its own mean the liver has failed. Many people improve once the trigger is treated. The doctor will check blood tests and other signs to judge how well the liver is working.
Can the sleep pattern go back to normal?
Often, yes. When encephalopathy is the cause, treating the trigger and using medicines such as lactulose usually improves sleep along with thinking. If itching, pain or fluid is the cause, treating those helps too. Some people with advanced disease keep a lighter, broken sleep despite best efforts.
Which sleeping tablets are safe with liver disease?
Only the treating doctor can answer that for one person. Many common sleeping and calming medicines can bring on or deepen confusion in liver disease. Do not buy or share one. Ask the team instead, because treating the cause usually works better than a tablet.
Should we wake him during the day?
Gently, yes. Sit him up for meals and medicines, open the curtains, and keep naps short. If he is very hard to wake, or seems confused when he does wake, that is no longer just poor sleep. Call the team the same day, or go to hospital if he cannot be woken properly.
Why does the itching keep him awake?
Itching from jaundice is often worse at night, when there is less to distract from it and the bed is warm. It has its own treatments. Read itching and what helps and mention it to the doctor, because it is easy to overlook.
Is rifaximin used for sleep problems?
Rifaximin is sometimes added to lactulose to prevent repeat episodes of encephalopathy. It is not a sleeping medicine. Whether it suits a particular person is a decision for the liver doctor or oncologist, and availability and cost in India should be checked with them.
Could this be depression instead?
It could, and the two can occur together. Low mood also changes sleep and energy. The doctor will look for signs that point one way or the other. If you are worried about mood, say so clearly, because emotional support is part of cancer care too.
Who should we call about this?
Call the doctor who treats the liver or the cancer, or the CION helpline, and describe the pattern you have noticed. Someone will help you decide whether a clinic visit is needed this week. If the person cannot be woken, has a fever or is bleeding, go to hospital today.
