Fatty liver disease and gallstones are common hepatobiliary conditions affecting millions across the UK, often sharing overlapping risk factors such as obesity, type 2 diabetes, and metabolic syndrome. Whilst fatty liver disease involves excess fat accumulation within liver cells, gallstones are solid deposits forming in the gallbladder. Both conditions frequently remain asymptomatic for extended periods, making early recognition of symptoms crucial. Understanding the warning signs—from vague upper abdominal discomfort to severe pain requiring urgent attention—enables timely medical evaluation and appropriate management, potentially preventing serious complications.
Summary: Fatty liver disease often causes no symptoms initially, whilst gallstones typically produce sudden severe upper abdominal pain after eating, though two-thirds of people with gallstones remain symptom-free.
- Fatty liver disease is frequently asymptomatic; when symptoms occur, they include persistent fatigue, vague upper right abdominal discomfort, and unexplained weakness.
- Gallstones cause biliary colic—sudden, severe, steady pain in the upper abdomen lasting 30 minutes to several hours, often after fatty meals and radiating to the right shoulder blade.
- Both conditions share common risk factors including obesity, type 2 diabetes, dyslipidaemia, and metabolic syndrome, and may coexist in the same patient.
- Complications requiring urgent medical attention include jaundice, high fever with rigors, persistent severe abdominal pain, and dark urine with pale stools.
- Abdominal ultrasound can identify both conditions simultaneously, whilst the Enhanced Liver Fibrosis (ELF) test assesses advanced fibrosis in confirmed NAFLD cases.
- Gradual weight loss of 0.5–1 kg per week is recommended for fatty liver disease, as rapid weight loss increases gallstone formation risk.

Understanding Fatty Liver and Gallstones
Fatty liver disease and gallstones are two distinct hepatobiliary conditions that can affect individuals independently or, in some cases, coexist. Fatty liver disease, medically termed hepatic steatosis, occurs when excess fat accumulates within liver cells. This condition is broadly categorised into non-alcoholic fatty liver disease (NAFLD), which affects people who drink little to no alcohol, and alcohol-related fatty liver disease (ARLD). NAFLD has become increasingly prevalent in the UK, affecting approximately one in three adults, often associated with obesity, type 2 diabetes, and metabolic syndrome.
Gallstones, conversely, are solid deposits that form within the gallbladder—a small organ situated beneath the liver that stores bile. These stones vary in size from tiny grains to golf ball-sized masses and develop when bile contains excessive cholesterol, bilirubin, or insufficient bile salts to keep these substances dissolved. Cholesterol stones account for approximately 80% of gallstones in Western populations.
Whilst these conditions affect different parts of the hepatobiliary system, they share common risk factors including obesity, type 2 diabetes, dyslipidaemia, and metabolic syndrome. Rapid weight loss is a recognised risk factor specifically for gallstone formation. Additional gallstone risk factors include female sex, increasing age, pregnancy, and oestrogen therapy. The liver produces bile, which the gallbladder stores and releases to aid fat digestion. Disruptions in this finely balanced system can predispose individuals to both conditions. Understanding the relationship between fatty liver and gallstones helps patients recognise symptoms early and seek appropriate medical evaluation. Both conditions can remain asymptomatic for extended periods, making awareness of potential warning signs particularly important for at-risk populations.
Common Symptoms of Fatty Liver Disease
Fatty liver disease is often called a 'silent' condition because many people experience no symptoms whatsoever, particularly in the early stages. The condition is frequently discovered incidentally during abdominal imaging performed for unrelated reasons or when investigating persistently abnormal liver function tests. This asymptomatic nature means fatty liver can progress undetected for years. It is important to note that many people with NAFLD have normal liver blood tests, and normal results do not exclude the condition.
When symptoms do manifest, they tend to be non-specific and subtle. Patients may report:
-
Persistent fatigue and general malaise that doesn't improve with rest
-
Vague discomfort or fullness in the upper right abdomen, beneath the rib cage
-
Unexplained weakness affecting daily activities
-
Occasional mild abdominal pain in the right upper quadrant
As fatty liver disease advances to non-alcoholic steatohepatitis (NASH)—where inflammation and liver cell damage occur—symptoms may become more pronounced, though many patients remain asymptomatic even at this stage. In advanced cases progressing to cirrhosis (severe scarring), more serious manifestations emerge including jaundice (yellowing of skin and eyes), ascites (abdominal fluid accumulation), peripheral oedema (leg swelling), easy bruising, and confusion.
It's important to note that symptom severity doesn't necessarily correlate with disease severity. Someone with significant hepatic steatosis may feel entirely well, whilst another with mild fat accumulation might experience fatigue. This disconnect underscores the importance of appropriate investigation when NAFLD is suspected—for example, if imaging incidentally shows hepatic steatosis or if liver function tests remain persistently abnormal after initial assessment. NICE does not recommend routine screening of at-risk adults for NAFLD. However, in adults with confirmed NAFLD, the Enhanced Liver Fibrosis (ELF) test should be used to assess for advanced fibrosis, with repeat testing typically every three years in those without advanced disease.
Recognising Gallstone Symptoms
Approximately two-thirds of people with gallstones experience no symptoms and may remain unaware of their presence indefinitely. These 'silent' gallstones typically require no treatment and are often discovered incidentally during imaging for other conditions. However, when gallstones obstruct the bile ducts or irritate the gallbladder lining, they can cause characteristic symptoms.
The hallmark symptom is biliary colic—sudden, severe, steady pain in the upper right abdomen or centre of the abdomen (epigastrium), just below the breastbone. This pain:
-
Typically occurs after eating, particularly following fatty or large meals, or may wake you at night
-
May radiate to the right shoulder blade or back
-
Usually lasts from 30 minutes to several hours
-
Is constant and steady rather than cramping or colicky
-
May be accompanied by nausea and vomiting
Whilst some people report non-specific symptoms such as indigestion, bloating, or excessive wind, these are not reliable indicators of gallstones and occur commonly in the general population.
When gallstones cause complications, symptoms become more severe and require urgent medical attention. Acute cholecystitis (gallbladder inflammation) presents with persistent severe pain lasting beyond six hours, fever, rapid heartbeat, and tenderness when the upper right abdomen is touched. If a stone blocks the common bile duct, jaundice develops—yellowing of the skin and whites of the eyes—alongside dark urine and pale, clay-coloured stools. Cholangitis (bile duct infection) causes fever with rigors (shaking chills), jaundice, and may progress to confusion or collapse, requiring emergency hospital treatment. Gallstone pancreatitis presents with severe epigastric pain radiating through to the back, persistent vomiting, and feeling very unwell. These complications require urgent medical assessment. Patients experiencing severe, persistent abdominal pain, high fever with rigors, jaundice, or signs of severe illness should call 999 or attend A&E immediately.
When Fatty Liver and Gallstones Occur Together
The coexistence of fatty liver disease and gallstones is not uncommon, as both conditions share overlapping risk factors and pathophysiological mechanisms. Obesity, insulin resistance, metabolic syndrome, and dyslipidaemia predispose individuals to both hepatic steatosis and cholesterol gallstone formation. Studies suggest that people with NAFLD have a higher prevalence of gallstones compared to the general population, though the relationship between the two conditions is complex.
When both conditions are present, symptom attribution can become challenging. Upper abdominal discomfort might originate from either condition, making clinical assessment more complex. Patients may experience:
-
Overlapping right upper quadrant discomfort that's difficult to characterise
-
Post-prandial symptoms (after eating) from both gallbladder dysfunction and metabolic disturbance
-
Fatigue potentially attributable to either condition
-
Non-specific digestive symptoms including bloating and nausea
The presence of both conditions may also complicate management decisions. For instance, weight loss is recommended for fatty liver disease to improve hepatic steatosis and metabolic health. However, rapid weight loss can increase gallstone formation risk by altering bile composition. To minimise this risk whilst improving NAFLD, aim for gradual weight loss of approximately 0.5–1 kg per week.
Diagnostic imaging, particularly abdominal ultrasound, can identify both conditions simultaneously. This non-invasive investigation visualises liver echogenicity (brightness indicating fat content) and detects gallstones with high sensitivity. Blood tests assessing liver function (ALT, AST, GGT, ALP, bilirubin) help determine whether abnormalities suggest hepatocellular injury (fatty liver) or biliary obstruction (gallstones). When both conditions coexist, a comprehensive metabolic assessment becomes essential. In adults with confirmed NAFLD, the Enhanced Liver Fibrosis (ELF) test should be used to assess for advanced fibrosis and guide further management, with repeat testing typically every three years. A tailored management plan addressing shared metabolic risk factors—including weight management, physical activity, and optimisation of diabetes and lipid control—is crucial.
When to Seek Medical Advice
Understanding when to seek medical attention is crucial for preventing complications from both fatty liver disease and gallstones. For routine, non-urgent concerns, patients should arrange a GP appointment if they experience:
-
Persistent fatigue that affects daily functioning and doesn't improve with rest
-
Unexplained upper abdominal discomfort lasting more than a few days
-
Recurrent episodes of biliary-type pain following meals
-
Known risk factors (obesity, diabetes, high cholesterol) and incidental findings on imaging or blood tests suggesting liver or gallbladder disease
Urgent medical attention is required for symptoms suggesting complications. Contact NHS 111 immediately or attend A&E if experiencing:
-
Severe, persistent abdominal pain lasting several hours, particularly in the upper right abdomen or epigastrium
-
High fever (above 38°C) accompanied by abdominal pain, especially with rigors (shaking chills)
-
Jaundice—yellowing of the skin or whites of the eyes
-
Dark urine combined with pale, clay-coloured stools
-
Persistent vomiting preventing fluid intake
-
Severe pain radiating to the back or shoulder
Call 999 or go immediately to A&E if you experience signs of severe infection or sepsis, including fever with rigors and jaundice, confusion, drowsiness, rapid breathing, or feeling extremely unwell. These symptoms may indicate acute cholecystitis, cholangitis (bile duct infection), bile duct obstruction, gallstone pancreatitis, or other serious complications requiring prompt investigation and treatment. Delayed presentation can lead to severe infections, organ damage, or life-threatening illness.
For patients already diagnosed with fatty liver disease, regular monitoring through GP appointments is important. In adults with confirmed NAFLD, NICE recommends using the Enhanced Liver Fibrosis (ELF) test to assess for advanced fibrosis, with repeat testing typically every three years in those without advanced disease. Periodic assessment of metabolic parameters—including weight, blood glucose, lipid profile, and blood pressure—is also essential. Those with gallstones experiencing increasing frequency or severity of biliary colic should discuss management options with their GP. Laparoscopic cholecystectomy (keyhole gallbladder removal) is usually offered to prevent emergency complications in people with symptomatic gallstones. Early engagement with healthcare services enables timely intervention, reduces complication risks, and facilitates evidence-based management of both conditions.
Frequently Asked Questions
What are the early warning signs of fatty liver and gallstones?
Fatty liver disease often produces no early symptoms, though some people experience persistent fatigue and vague upper right abdominal discomfort. Gallstones typically cause sudden, severe upper abdominal pain after eating fatty meals, lasting 30 minutes to several hours and sometimes radiating to the right shoulder blade.
Can you have fatty liver disease and gallstones at the same time?
Yes, fatty liver disease and gallstones frequently coexist because they share common risk factors including obesity, type 2 diabetes, and metabolic syndrome. When both conditions are present, symptom attribution becomes challenging as upper abdominal discomfort may originate from either condition.
How do I know if my abdominal pain is from gallstones or fatty liver?
Gallstone pain (biliary colic) is typically sudden, severe, and occurs after eating, lasting 30 minutes to several hours with radiation to the right shoulder blade. Fatty liver discomfort is usually vague, persistent, and less severe, though many people with fatty liver experience no pain at all.
When should I go to A&E for symptoms of fatty liver or gallstones?
Seek emergency care immediately if you experience jaundice (yellowing of skin or eyes), high fever with rigors and abdominal pain, severe persistent abdominal pain lasting several hours, or signs of severe infection including confusion and rapid breathing. These symptoms may indicate serious complications such as cholangitis, acute cholecystitis, or gallstone pancreatitis requiring urgent treatment.
Will losing weight help both fatty liver and gallstones?
Gradual weight loss of approximately 0.5–1 kg per week improves fatty liver disease and reduces metabolic risk factors. However, rapid weight loss increases gallstone formation risk by altering bile composition, so controlled, steady weight reduction is essential when both conditions are present.
What tests diagnose fatty liver disease and gallstones together?
Abdominal ultrasound can identify both conditions simultaneously by visualising liver fat content and detecting gallstones with high sensitivity. Blood tests assess liver function to distinguish hepatocellular injury from biliary obstruction, whilst the Enhanced Liver Fibrosis (ELF) test evaluates advanced fibrosis in confirmed NAFLD cases.
