Gallstones are a common digestive problem that affects many people, particularly middle-aged women. Although they often cause no symptoms, when they do, it can be an extremely unpleasant and painful experience. Many people are apprehensive about possible medical interventions, yet with the right knowledge, there is a great deal we can do to prevent them.
This article has been written to provide an easy-to-understand, medically sound explanation of gallstones. We’ll explain why these stones form, what the most common risk factors are, and, most importantly, how you can reduce your chances of developing them through simple lifestyle changes. Our aim is to help you take more confident steps to look after your health using the information provided, and to reduce your fear of medical procedures.
What exactly is a gallstone?
Az epekő az epehólyagban képződő szilárd lerakódás. Az epehólyag egy kis, körte alakú szerv a máj alatt, amelynek feladata az epe tárolása. Az epe egy folyadék, amelyet a máj termel, és segít a zsírok emésztésében. Amikor az epe összetevőinek – koleszterin, epesók, bilirubin – egyensúlya felborul, kristályok képződhetnek, amelyek idővel kövekké állhatnak össze.
Types of gallstones
Gallstones are classified into two main groups based on their composition:
- Cholesterol stones: This is the most common type, accounting for approximately 75% of cases. They are usually yellowish in colour. They form when there is too much cholesterol in the bile and the bile acids are unable to dissolve it. This excess cholesterol crystallises and forms stones.
- Pigment stones: These are darker in colour – black or brown – and develop when there is too much bilirubin in the bile. Bilirubin is a substance produced when red blood cells break down. Certain conditions, such as liver cirrhosis or blood disorders, can increase the risk of developing pigment stones.
Why do gallstones develop? The most important risk factors
There are a number of factors that may contribute to the development of gallstones. Although they can affect anyone, certain groups are at greater risk.
The most common risk factors:
- Age: As we get older, particularly from the age of 40 onwards, the risk increases.
- Female: Gallstones are two to three times more common in women, which can be explained by the effect of female hormones, particularly oestrogen.
- Pregnancy: Hormonal changes during pregnancy and increased cholesterol levels also contribute to the formation of stones.
- Family accumulation: If there is a family history of gallstones, you are also more likely to develop them.
- Obesity: Being overweight or obese increases cholesterol levels in the bile, which can lead to the formation of gallstones.
- Rapid weight loss: As a result of drastic diets and sudden weight loss (for example, following gastric bypass surgery), the liver releases extra cholesterol into the bile, which is also a risk factor.
- Etrend: A diet high in cholesterol and fat but low in fibre may contribute to the formation of cholesterol stones.
- Certain medicines: Medicines containing oestrogen (e.g. contraceptives, hormone replacement therapy) and certain cholesterol-lowering medicines (fibrates) may increase the risk.
- Other diseases: Diabetes, Crohn’s disease, liver cirrhosis and sickle cell anaemia may also increase the risk of gallstones.
Symptoms and possible complications of gallstones
Sokan élnek epekővel anélkül, hogy tudnának róla, mert a kövek semmilyen panaszt nem okoznak. Ezeket „néma köveknek” nevezzük. A problémák akkor kezdődnek, amikor egy kő elmozdul és elzárja az epeutat.
A typical stomach cramp
A legjellemzőbb tünet az epegörcs (biliáris kólika), amely egy hirtelen fellépő, erős, görcsös fájdalom a has jobb felső részén vagy a gyomorszáj környékén. A fájdalom kisugározhat a hátba, a lapockák közé vagy a jobb vállba. Az epegörcsöt gyakran kíséri hányinger és hányás. Jellemzően zsíros, nehéz ételek fogyasztása után jelentkezik, és néhány perctől akár több órán át is tarthat.
More serious complications
If the blockage of the bile duct is persistent, more serious complications may develop, requiring immediate medical attention. In such cases, other symptoms appear alongside the pain:
- Inflammation of the gallbladder (cholecystitis): It is characterised by persistent, severe pain, a fever and chills.
- Bile duct obstruction: If the stone enters the common bile duct, it can cause jaundice (a yellowish discolouration of the skin and the whites of the eyes), dark urine and pale stools.
- Pancreatitis (inflammation of the pancreas): If the stone blocks the opening of the pancreatic duct, a life-threatening condition known as pancreatitis, which is characterised by severe abdominal pain, may develop.
If you experience symptoms such as a fever, chills, jaundice or persistent, severe abdominal pain, seek medical attention immediately!
How can gallstones be prevented? Medical advice for everyday life
Although we cannot influence genetic predisposition or age, there is much we can do through our lifestyle to prevent the formation of gallstones. The key is to achieve and maintain a healthy weight and to follow a balanced diet.
1. Maintain your ideal weight! Az elhízás az egyik legjelentősebb rizikófaktor. A testsúly normalizálása csökkenti az epe koleszterinszintjét. Fontos azonban, hogy a fogyás fokozatos legyen! A túlságosan gyors súlyvesztés (heti 1-1,5 kg-nál több) éppúgy kockázatos, mint a túlsúly. A koplalás és a nagyon alacsony kalóriatartalmú diéták kerülendők. Törekedjen a lassú, fenntartható fogyásra, heti 0,5-1 kg súlycsökkenést megcélozva.
2. Get some regular exercise! Physical activity not only helps with weight management, but also reduces the risk of gallstones in its own right. Exercise improves metabolism and aids digestion. At least 30 minutes of moderate-intensity exercise a day (e.g. brisk walking, cycling, swimming) already has a significant positive effect.
3. Change your eating habits! The basis of a gallstone-preventative diet is a diet rich in fibre and low in fat and cholesterol.
- Eat plenty of fibre: Fibre aids digestion and lowers cholesterol levels. Eat plenty of vegetables, fruit, wholegrains (e.g. porridge, brown rice, wholemeal bread) and pulses (e.g. lentils, beans).
- Choose healthy fats: Avoid saturated fats (fatty meats, processed meats, full-fat dairy products, butter) and trans fats (processed foods, margarines). Instead, eat foods containing unsaturated fatty acids, such as olive oil, avocados, nuts and oilseeds (in moderation), as well as oily fish (e.g. salmon).
- Cut down on your intake of refined carbohydrates and sugar: Products made from white flour (white bread, pastries) and sugary foods and drinks may increase the risk of gallstones.
- Eat regularly: Fasting and skipping meals can slow down the emptying of the gallbladder, which can lead to the formation of stones. Try to eat several small meals a day.
4. Make sure you drink enough fluids! Adequate hydration is essential for healthy digestion. Drink at least 2–2.5 litres of fluid a day, primarily water.
Interestingly, several studies have found a link between regular coffee consumption and a lower risk of gallstones. The exact mechanism behind this is not yet fully understood, but it appears that coffee stimulates the contraction of the gallbladder.
When should you see a gastroenterologist?
If you have symptoms suggestive of gallstones, or if you are in a high-risk group and would like to make sure that everything is fine, it is worth consulting a gastroenterologist. The examination is usually painless and straightforward.
A leggyakoribb diagnosztikai módszer a hasi ultrahang, amely gyors és megbízható képet ad az epehólyag állapotáról és a kövek jelenlétéről. Ha a diagnózis bizonytalan, vagy szövődmény gyanúja merül fel, további vizsgálatokra (pl. laborvizsgálat, CT, MRCP, ERCP) lehet szükség.

Summary: You’re in control
Az epekövesség egy gyakori, de nagymértékben megelőzhető állapot. Bár bizonyos rizikófaktorokat, mint a kor vagy a genetika, nem tudunk befolyásolni, az életmódunkkal – különösen a táplálkozással és a testmozgással – sokat tehetünk a kockázat csökkentéséért.
Achieving and maintaining a healthy weight, following a diet rich in fibre and low in fat, taking regular exercise and drinking enough fluids all help to keep your gallbladder healthy. Remember, prevention is always easier than treating an existing condition.
