The short answer
Why do hiccups go on and on in liver cancer?
Hiccups that last for days are usually a sign that something is pressing on or irritating the diaphragm, the sheet of muscle under the lungs. In liver cancer the most common reasons are a large liver, fluid in the abdomen or a stretched stomach. Most of these causes can be found, and most persistent hiccups can be eased.
Why it matters more than it sounds
Hiccups that do not stop are exhausting. They break sleep, make eating hard, hurt a sore abdomen and can leave a person too tired to talk. Families are often told it will settle on its own. Sometimes it does. When it has gone on for more than two days, it deserves a proper look and a proper plan.
Who this page is for
This applies whether the cancer started in the liver or spread there from somewhere else, because the liver presses on the diaphragm in the same way in both. It does not apply to an ordinary bout of hiccups that stops within an hour or two, which almost everyone gets and which means nothing.
Long-lasting hiccups are a symptom to treat, not something to put up with quietly.Where they come from
What usually keeps the hiccups going?
Often there is more than one cause at once. Finding each one is what makes treatment work.
Something pressing on the diaphragm
A tumour near the top of the liver, an enlarged liver or fluid in the abdomen can push up on the diaphragm and set off the reflex again and again. Read more about why fluid collects in the abdomen.
A stretched or slow stomach
A liver that takes up more room squeezes the stomach. Wind, acid coming back up and a stomach that empties slowly are all common triggers.
Often comes with
- Feeling full after a few mouthfuls
- Burping or heartburn
- Nausea after meals
Changes in the blood
Low salt levels, kidney strain and a raised blood sugar can all irritate the nerves that control the hiccup reflex. A simple blood test checks for these.
Treatment and medicines
Steroids, some chemotherapy medicines and some sedatives can trigger hiccups. A procedure on the liver, such as TACE or radiation, can irritate the diaphragm for a while afterwards.
Never stop a prescribed medicine on your own. Ask first.Not sure whether this applies to you?

When hiccups come with something else, go to hospital today
Go to the nearest emergency department today if hiccups come with vomiting blood or black stools, new confusion or drowsiness, fever or pain with a swollen abdomen, chest pain, or real difficulty breathing. Go today as well if the person cannot keep any fluid down. See your oncology team this week if the hiccups have lasted more than two days, or stop the person eating or sleeping.
At the appointment
What will the doctor do about persistent hiccups?
Ask when it started and what changed
A new medicine, a recent procedure, a swelling belly or a change in eating are the first clues. Bring the full list of tablets, including anything bought without a prescription.
Examine the abdomen and check the blood
The doctor feels for fluid and an enlarged liver, and checks salt levels, kidney function and blood sugar. A scan is arranged only if the answer would change the plan.
Treat the cause first
Draining tense fluid, settling acid, easing wind or correcting a low salt level can stop hiccups without any hiccup medicine at all.
Then try a medicine if needed
If hiccups carry on, a medicine that calms the reflex can be tried. The choice depends on how well the liver and kidneys are working, so the team starts carefully and reviews it within a few days.
Names you may hear
Which medicines are used for hiccups that will not stop?
- Acid-reducing tablets
- Used when acid coming back up is part of the problem. Often the first thing tried, because they are gentle on most people.
- Metoclopramide
- Helps the stomach empty. Useful when fullness and nausea come with the hiccups. It can cause restlessness in some people.
- Baclofen
- A muscle relaxant that calms the reflex. It leaves the body through the kidneys, so it needs care when kidney function is low.
- Chlorpromazine or haloperidol
- Older medicines that can work well. Both can cause drowsiness, which matters in someone whose liver is struggling.
- Gabapentin
- Sometimes used when a nerve is thought to be irritated. It can also cause sleepiness.

Commonly believed
Four things families tell us about hiccups, and what is true
"Hiccups mean the cancer is getting worse."
Not necessarily. A full stomach, a new tablet or fluid that can be drained are far more common reasons. Only an examination and a blood test can tell which applies.
"Nothing can be done, you just have to wait."
Several things can be done. Treating the cause often works, and medicines are there when it does not. Ask for a plan rather than waiting.
"A home remedy will stop it."
Sipping cold water or holding the breath can stop a short bout. They rarely stop hiccups that have gone on for days. Avoid herbal liver tonics, because some can harm a damaged liver.
"A sleeping tablet will help them rest through it."
Sedatives can be risky in liver disease and can tip a person into confusion. Read why on our page about sleeping tablets and sedatives before asking for one.
Being straight with you
What this page cannot tell you
It cannot tell you why your own hiccups have started or which medicine will suit you. That depends on an examination, blood results and how well the liver and kidneys are working today. Evidence on hiccup medicines is also thin. Most of it comes from small studies and from the experience of doctors, so a first choice that does not work is normal, not a failure.
Who should look after it
Your oncology team, or a palliative care doctor working with them, is the right person to ask. Palliative care is symptom care, and it runs alongside cancer treatment, not instead of it. CION's medical oncologists see this symptom often and can plan its treatment with you.
Who this does not apply to
If hiccups started straight after a TACE procedure, read about what is expected after embolisation and tell the team who did it. If breathlessness is the bigger problem, that needs its own assessment.
If you are unsure whether to wait, call the helpline and describe what is happening.Questions we are asked
Common questions about hiccups in liver cancer
How long is too long for hiccups?
Hiccups that last more than two days are called persistent and deserve a doctor's attention. If they stop the person eating, drinking or sleeping, do not wait that long. Call the oncology team sooner and describe what is happening, including any new medicine or recent procedure.
Can draining the fluid stop the hiccups?
Sometimes, yes. When a tense, swollen abdomen is pushing on the diaphragm, removing some of the fluid can bring quick relief. It does not help every time, because there may be other causes too. Your team will decide whether a drain is worth doing.
Are hiccups a side effect of chemotherapy or steroids?
They can be. Steroids given with chemotherapy are a well-known trigger, and some chemotherapy medicines are too. Hiccups often start within a day or two of treatment and fade. Tell the team, because the anti-sickness plan or the steroid can sometimes be adjusted.
Is it safe to take hiccup medicine with a damaged liver?
Often, yes, with care. Several hiccup medicines cause drowsiness or are cleared by the liver or kidneys. The doctor chooses one that suits the current blood results, starts low and checks how the person responds. Never borrow a medicine prescribed for someone else.
What can we try at home while waiting?
Small, frequent meals instead of large ones, sitting upright after eating and avoiding fizzy drinks can help. Sipping cold water slowly is harmless to try. Avoid herbal tonics and over-the-counter remedies without asking, because some strain a damaged liver.
Can hiccups cause other problems?
Yes. Days of hiccups can lead to poor sleep, weight loss, dehydration, pain around the ribs and low mood. Some people also bring food back up. These knock-on effects are a good reason to treat persistent hiccups early rather than waiting for them to wear off.
Do hiccups mean the end is near?
No. Hiccups happen at every stage of liver disease and often have a simple, treatable cause. They are not a sign of how much time someone has. If you are worried about what lies ahead, ask the oncologist directly. That is a fair question to ask.
Who do we call if the hiccups will not stop?
Start with the oncology team who are treating the cancer. If you are not sure who to approach, call the CION helpline and someone will help you arrange a review. If hiccups come with any of the warning signs above, go to hospital today instead.
