Gallstones: Symptoms, Diet & When Surgery Is Needed
An honest, plain-English guide to gallstone symptoms — what they typically feel like, how they can differ, when tummy pain is an emergency, whether a low-fat diet helps, and your NHS and private options for diagnosis and gallbladder removal. This is general information to help you understand the condition — it is not a diagnosis, and not a substitute for seeing your GP.
Read this first
This page is general health information, not medical advice, and cannot diagnose you. Gallstone symptoms overlap with many other conditions, so only a doctor can tell you what’s actually causing your symptoms. If you have recurring or severe tummy pain, see your GP. If you have pain lasting more than a few hours, a high temperature, or yellowing of your skin or eyes, this can be a medical emergency — call 999 or NHS 111, or go to A&E.
Quick Answer
Gallstones are very common — around 1 in 10 UK adults have them — and most people never get any symptoms and need no treatment. When gallstones do cause problems, the classic symptom is biliary colic: a sudden pain in the upper-right or upper-central tummy, often after fatty food, sometimes spreading to the right shoulder blade, lasting minutes to a few hours.
Most symptoms don’t need emergency care, but some do (see the red-flags below). Gallstones causing repeated pain are usually treated with keyhole surgery to remove the gallbladder — on the NHS, or privately for speed. The one thing this page won’t do is diagnose you: recurring or severe tummy pain always needs a GP.

What Gallstone Symptoms Feel Like
Gallstones are small stones, usually made of cholesterol, that form in the gallbladder — a small organ under the liver that helps digest fat. Here’s the reassuring part most people don’t realise: the majority of gallstones cause no symptoms at all, are often found by chance, and need no treatment. When they do cause symptoms, it’s usually because a stone temporarily blocks a duct. The classic symptom is biliary colic:
- Where: sudden pain in the upper-right tummy, or the centre just below the breastbone
- Spreading: often radiates towards the right shoulder blade or back
- Trigger: frequently comes on after a fatty or large meal
- How long: lasts from a few minutes to a few hours, then eases
- With it: can come with feeling sick (nausea) or being sick
The honest caveat that matters: these symptoms overlap with lots of other conditions — indigestion, stomach ulcers, and others — so pain like this does not automatically mean gallstones, and this page cannot tell you that you have them. What recurring or severe upper-tummy pain does mean is that it’s worth getting checked by a GP, who can arrange the right test.
Symptoms in Women
Gallstones are more common in women than men, and a lot of people specifically search for how symptoms show up in women — so it’s worth addressing honestly. The core symptom is the same in women and men: biliary colic pain in the upper-right tummy. What differs is risk, not really the symptom itself — pregnancy, the contraceptive pill and rapid weight loss all raise the chance of developing gallstones. Some women also describe more general symptoms like bloating, indigestion and nausea, but these are non-specific — they have countless other causes and are not a reliable way to tell whether you have gallstones. So the takeaway is the same for everyone: persistent or severe symptoms need a proper assessment rather than self-diagnosis, because guessing from general symptoms is how the wrong cause gets missed.
Red flags — when to get urgent help
Most biliary colic settles, but gallstones can cause serious complications. Call 999, go to A&E, or call NHS 111 if you have: tummy pain lasting more than a few hours; a high temperature, shivering or feeling generally very unwell; yellowing of your skin or the whites of your eyes (jaundice); very dark pee or pale poo; or pain so intense you can’t get comfortable. These can signal gallbladder inflammation (cholecystitis), a blocked bile duct, infection or pancreatitis — all of which need hospital treatment. This is an NHS emergency, not something to arrange privately or wait on.
When It’s an Emergency
To be clear about the boundary, because it matters: ordinary biliary colic — pain that eases within an hour or two and settles — is something to see your GP about, not usually a 999 call. But the complications of gallstones genuinely are emergencies. Acute cholecystitis (the gallbladder becoming inflamed and infected) causes pain lasting longer than about five hours with a fever. Jaundice (yellow skin or eyes) means a stone may be blocking the bile duct. Pancreatitis causes severe, constant upper-tummy pain and usually needs hospital admission. If any of these happen, the NHS emergency route is the right one — don’t drive yourself to A&E if you’re very unwell; call 999. Going private is for planned diagnosis and treatment, never for an acute emergency like this.
Does a Low-Fat Diet Help?
A common and fair question, and the honest answer is: a low-fat diet can help manage symptoms, but it won’t cure gallstones or dissolve them. Because fatty food triggers the gallbladder to contract, cutting back on fat can reduce how often you get biliary colic attacks — NHS guidance notes it can prevent recurrent episodes in a meaningful proportion of people. So it’s a useful way to calm symptoms while you wait for assessment or treatment. What it isn’t is a fix: if gallstones are causing you repeated pain, diet alone rarely makes the problem go away, and the definitive treatment remains removing the gallbladder. Think of diet as symptom management, not a substitute for getting the underlying issue looked at.
Diagnosis & Treatment
If a GP suspects gallstones, the usual first test is an ultrasound scan of the tummy — quick, painless and good at spotting stones — sometimes alongside blood tests to check how the liver is working, and occasionally an MRI-type scan if a stone in the bile duct is suspected. On treatment, the principle is simple: gallstones causing no symptoms are usually left alone, while stones causing repeated pain or complications are usually treated by removing the gallbladder. This is done by keyhole (laparoscopic) surgery — a cholecystectomy — and you can live a completely normal life without a gallbladder. If you want to understand the procedure, recovery and costs in detail, our guide to private gallbladder removal surgery covers it fully, and the diagnostic step — the scan — is explained in our private ultrasound cost guide. Blood tests to check liver function are covered in our liver function test guide.
NHS vs Going Private
Gallstone diagnosis and surgery are both available on the NHS — and for many people that’s the right route, especially as gallbladder removal is a common, well-established operation. The reason some people go private is speed: if you’re getting repeated painful attacks and facing a long NHS wait for a scan or surgery, paying privately can mean being seen and treated in weeks rather than many months. Going private is self-pay here (see the honest note on insurance below) — you can get a private ultrasound quickly to confirm what’s going on, then a planned cholecystectomy if needed. The cost context is in our private operation costs guide and hospital price list, and if you’d need a referral first, our GP referral guide explains how it works. Related digestive investigations like an endoscopy are sometimes used to rule out other causes of upper-tummy pain.
The Honest Truth About Insurance
This is worth being completely straight about, because it’s where people waste money. Private health insurance does not cover pre-existing conditions. If you already have gallstone symptoms and then take out a new policy, that policy will not cover the investigation or treatment of your gallstones — they began before the policy started, so they’re excluded. Buying insurance now hoping it’ll pay for a problem you already have simply doesn’t work, and any honest adviser will tell you the same. So if you already have symptoms, your two realistic routes are the NHS, or self-paying privately for faster treatment. Where health insurance genuinely helps is protecting you against future, unrelated conditions — giving you fast diagnosis and treatment, without the wait, for things that haven’t happened yet. That’s a sensible reason to consider cover, and our guide to what insurance covers for diagnostics explains the boundary in full. Just not for something you’re already dealing with.
FAQs: Gallstone Symptoms (2026)
What are the symptoms of gallstones?
Most people with gallstones have no symptoms at all and never need treatment. When symptoms do occur, the most common is biliary colic: a sudden, often severe pain in the upper right or upper central part of the tummy, which can spread towards the right shoulder blade or back. It’s frequently triggered by fatty food, can last from a few minutes to a few hours, and may come with nausea or vomiting. This information is general and not a diagnosis, because these symptoms overlap with other conditions. If you have tummy pain that keeps coming back, or pain lasting more than a few hours, see your GP so the cause can be properly checked.
Are gallstone symptoms different in women?
The core symptom, biliary colic pain in the upper right tummy, is the same in women and men. Gallstones are more common in women, and risk factors include pregnancy, the contraceptive pill and rapid weight loss. Some women report symptoms like bloating, indigestion and nausea, though these are non-specific and can have many other causes, so they are not a reliable way to self-diagnose. Whatever your sex, the honest position is the same: recurring or severe upper-tummy pain should be assessed by a GP rather than self-diagnosed, because the symptoms overlap with other conditions that need different treatment.
When are gallstones an emergency?
Seek urgent help if a gallstone causes a complication. Call 999 or go to A&E, or call 111 for advice, if you have tummy pain lasting more than a few hours, especially with a high temperature or shivering, yellowing of the skin or the whites of the eyes (jaundice), very dark pee or pale poo, or intense pain you can’t get comfortable with. These can signal inflammation of the gallbladder (cholecystitis), a blocked bile duct, infection (cholangitis) or inflammation of the pancreas (pancreatitis), which are potentially serious and need hospital treatment. This is an NHS emergency, not something to wait on or arrange privately.
Does a low-fat diet help gallstones?
A low-fat diet won’t dissolve gallstones or cure them, but it can help reduce how often symptoms flare, because fatty food triggers the gallbladder to contract and can bring on biliary colic. NHS guidance suggests a lower-fat diet can prevent recurrent episodes in a proportion of people. It’s a way to manage symptoms while you wait for assessment or treatment, not a substitute for it. If gallstones are causing you repeated pain, diet alone rarely resolves the problem, and the definitive treatment is usually surgery to remove the gallbladder. Your GP or a specialist can advise what’s right for your situation.
How are gallstones diagnosed and treated?
Gallstones are usually diagnosed with an ultrasound scan, sometimes with blood tests to check liver function, and occasionally an MRI or specialist scan if a duct stone is suspected. Gallstones that cause no symptoms are usually left alone. When they cause repeated pain or complications, the standard treatment is keyhole (laparoscopic) surgery to remove the gallbladder, called a cholecystectomy. You can live a normal life without a gallbladder. This can be done on the NHS, or privately if you want faster diagnosis and treatment. The right path depends on your symptoms and how quickly you want to be seen, which a GP or specialist can help you weigh up.
Will health insurance cover gallstone treatment?
This is the honest bit: health insurance does not cover pre-existing conditions. If you already have gallstone symptoms, taking out a new policy will not cover investigation or treatment for them, because they began before the policy started. Health insurance is designed to cover new conditions that arise in the future, giving you fast diagnosis and treatment without long NHS waits. So if you already have symptoms, your realistic options are the NHS or paying privately (self-pay) for faster treatment. Insurance is worth considering for protecting yourself against future, unrelated conditions, not for something you already have.
Important Information
This 2026 guide is general health information only — it is not medical advice, cannot diagnose any condition, and is not a substitute for assessment by a qualified doctor. Gallstone symptoms overlap with other conditions; only a GP or specialist can determine the cause of your symptoms. Always seek your GP’s advice for persistent or worrying symptoms, and in an emergency — severe or prolonged pain, high temperature, or jaundice — call 999 or NHS 111. Health insurance covers new conditions arising after a policy starts, never pre-existing conditions, so it will not cover gallstones you already have. If you compare private health insurance quotes through this site, we may receive a commission from our FCA-regulated partners at no cost to you; this does not influence our guides.
