Cirrhosis: screening and follow-up in Luxembourg

Cirrhosis is a chronic liver disease in which liver tissue, damaged over many years, is gradually replaced by scar tissue that no longer works. Its causes are varied: alcohol, but also chronic viral hepatitis and fatty liver disease linked to excess weight or diabetes. The condition stays silent for a long time, yet it can be detected with a simple blood test and an ultrasound scan, and its progression can be stopped when the underlying cause is treated. In Luxembourg, the general practitioner is the first person to see for screening; they refer patients to a gastroenterologist or hepatologist when specialist follow-up is needed.

A liver that stays quiet far too long

The liver is a discreet organ. It filters the blood, produces essential proteins, stores energy and neutralises toxins — and it does all of this without ever hurting, because it contains almost no pain fibres. When an injury is repeated year after year, liver cells die and are replaced by scarring, much like burnt skin that heals as fibrous tissue. This widespread scarring process is what we call cirrhosis: the liver becomes hard and knobbly, and blood flows through it with increasing difficulty.

The trap lies in the organ's enormous reserve. A liver can lose a large share of its capacity before the slightest symptom appears. Someone can therefore live for years with developing cirrhosis, feel broadly well, and only discover the disease at an advanced stage. That is exactly why screening matters so much.

Many possible causes, none of them deserving judgement

In the popular imagination, cirrhosis means alcohol. The reality is broader. Regular alcohol consumption over many years is indeed a major cause — and alcohol dependence is an illness that can be treated, not a moral failing. But cirrhosis can also result from chronic viral hepatitis (hepatitis B or C), sometimes contracted decades earlier without the person ever knowing. And an increasingly common cause is metabolic fatty liver disease: fat building up in the liver, encouraged by excess weight, type 2 diabetes and a sedentary lifestyle, which can progress to inflammation and then fibrosis — without a single drink.

In other words, nobody has to justify their cirrhosis. Looking for the cause is not looking for a culprit: it means identifying the lever to act on, because treating the cause is what stops the disease.

Late signs, when the liver can no longer compensate

As long as the liver compensates, there is often nothing to notice, or only vague signs: lasting tiredness, loss of appetite, mild discomfort under the right ribs. The more telling signs come late, when the disease is advanced. The skin and the whites of the eyes may turn yellow (jaundice), the abdomen may swell because fluid accumulates, the legs may puff up, the skin may itch. Bruises appear easily, because the liver produces fewer clotting factors. Some people notice small red spider-like vessels on the chest, or unusual confusion towards the end of the day.

Vomiting blood or passing black stools signals digestive bleeding, a serious complication of cirrhosis: this is an emergency, and 112 must be called without delay.

Simple screening for those at risk

The good news is that nobody has to wait for those signs. A standard blood test measures liver enzymes and other markers that flag liver damage early; scores calculated from these results estimate the degree of fibrosis. An abdominal ultrasound, a painless examination without radiation, shows the appearance of the liver and any fat accumulation. The specialist may add an elastography, a type of ultrasound that measures liver stiffness and in most cases replaces the old biopsy.

Who should raise it with their GP? People who have drunk alcohol regularly for a long time, those living with type 2 diabetes, significant excess weight or metabolic syndrome, anyone who may have been exposed to hepatitis B or C, and those whose blood tests have already shown liver abnormalities. A simple check-up, free of judgement, tells you where you stand.

A disease whose progression can be stopped

Cirrhosis is not a sentence to inevitable decline. When the cause is treated, progression stops in the great majority of cases, and the liver can even recover part of its function, especially at early stages. In practice: stopping alcohol, with medical support rather than alone, changes the prognosis dramatically, even once cirrhosis is established. Chronic viral hepatitis now has highly effective treatments, prescribed by the specialist. For metabolic fatty liver disease, gradual weight loss, regular physical activity and good diabetes control reduce liver fat and inflammation.

In every case, a healthy lifestyle supports the liver: balanced eating, up-to-date hepatitis vaccinations where indicated, and caution with medicines and supplements taken without medical advice.

Follow-up: watching in order to act before complications

Once cirrhosis is diagnosed, regular follow-up is organised between the GP and the gastroenterologist or hepatologist. It relies on blood tests and ultrasound scans at set intervals, with a twofold aim: checking that the disease is not progressing, and detecting complications early, when they are far easier to treat — fluid in the abdomen, varicose veins in the oesophagus, and above all the risk of liver cancer, which ultrasound surveillance can pick up at a stage where treatment is possible. This follow-up is not a sword of Damocles: on the contrary, it is what allows people to live long and normal lives with a fragile liver.

In Luxembourg: an accessible care pathway

The pathway usually starts with the general practitioner, who prescribes the blood tests and ultrasound and then refers to a gastroenterologist if needed. Consultations, laboratory tests and imaging are covered by the national health fund under the usual reimbursement rules, detailed on the CNS website. People who wish to cut down or stop drinking can talk to their GP or turn to the country's specialised addiction services: asking for help for your liver and asking for help with alcohol are part of the same act of caring for your health, with no judgement attached.
