Alcohol-related diseases: what the French figures show
Alcohol is part of everyday social life, which makes its effects hard to see. Public health data, on the other hand, are precise and take us beyond mere impressions. In this article, Reset Laser reviews the documented harms, organ by organ, using official French figures, and above all looks at what remains reversible when you stop.
KEY TAKEAWAYS
- In France, 41,000 deaths were attributable to alcohol in 2015, or 7% of deaths among people aged 15 and over [1].
- Cancers come first with 16,000 deaths, ahead of cardiovascular diseases (9,900) and digestive diseases (6,800) [1].
- There is no risk-free threshold for cancer, as the mechanism relies on acetaldehyde [2].
- Alcohol is the leading cause of chronic pancreatitis [4].
- A large share of these harms stabilises or regresses after stopping.
The key figures in France
The reference study, published in the Bulletin épidémiologique hebdomadaire (the French weekly epidemiological bulletin), estimates the number of deaths attributable to alcohol in France in 2015 at 41,000: 30,000 among men and 11,000 among women, or 11% and 4% respectively of mortality among adults aged 15 and over [1].
The breakdown by cause sheds light on the rest of this article [1]:
| Cause of death | Deaths attributable to alcohol (2015) |
|---|---|
| Cancers | 16,000 |
| Cardiovascular diseases | 9,900 |
| Digestive diseases | 6,800 |
| External causes (accidents, suicides) | 5,400 |
| Other (mental and behavioural disorders, etc.) | over 3,000 |
In total, 7% of deaths among people aged 15 and over are attributable to alcohol [1]. These figures do not only concern very heavy drinking: premature mortality affects the whole drinking population.
The liver, the classic route
It is the organ that comes to mind first, and the progression is well described. It happens in three stages that can follow one another over years.
Steatosis, or fatty liver, is a build-up of fat in the liver cells. It is silent and reversible once you stop.
Alcoholic hepatitis is an inflammation, sometimes acute and severe, which can appear after a period of heavy drinking.
Cirrhosis is the gradual destruction of liver tissue, which is replaced by fibrosis. At this stage, established damage does not disappear, but stopping alcohol remains the factor that weighs most on how things develop.
The liver is a silent organ: abnormal blood test results appear long before symptoms. A liver function test is one of the checks your GP can request.

Laser auricular reflexology supports your journey, alongside your doctor’s care. A single session of about one hour, with personalised follow-up for 12 months.
Cancers, the least-known part
This is the figure that surprises people most: 16,000 cancer deaths are attributable to alcohol every year in France [1].
The mechanism relies mainly on acetaldehyde, the first breakdown product of ethanol, which damages DNA [2]. This mechanism works whatever the drink.
The sites affected include the upper aerodigestive tract (mouth, pharynx, larynx), the oesophagus, the breast, the colon and rectum, and the liver [2]. Breast cancer is the leading alcohol-induced cancer in women, and the risk rises even at low levels of drinking [2].
This point deserves to be stated clearly: there is no risk-free level of drinking when it comes to cancer. Lower-risk drinking guidelines limit the risk; they do not eliminate it.
The heart and blood vessels
Cardiovascular diseases account for around 9,900 attributable deaths a year [1].
Three main mechanisms are involved. High blood pressure, whose link with alcohol is dose-dependent and well quantified. Heart rhythm disorders, atrial fibrillation in particular, triggered by episodes of heavy drinking. And cardiomyopathy, a weakening of the heart muscle linked to chronic heavy drinking.
The brain
Neurological harm combines two mechanisms: the direct toxicity of alcohol and nutritional deficiencies, especially vitamin B1 deficiency [3].
The severe forms are Wernicke’s encephalopathy, a medical emergency, and Korsakoff syndrome, which leaves lasting memory damage [3]. Subtler cognitive problems, affecting attention, working memory and planning, are common long before these extreme forms.
What sets this damage apart, as explained in our dedicated article, is its potential for partial recovery after a prolonged period without alcohol.
The pancreas and digestive system
Digestive diseases account for 6,800 attributable deaths a year [1].
Alcohol is the leading cause of chronic pancreatitis, an inflammation that gradually destroys the pancreas and causes disabling pain, digestive problems and a risk of diabetes [4]. Acute alcohol-related pancreatitis is a hospital emergency.
On top of this come gastritis, reflux and poor nutrient absorption, which keep deficiencies going.
Mental health
Mental and behavioural disorders appear among the attributable causes of death [1], but the real burden lies elsewhere: in everyday life.
Alcohol and depression feed each other. Alcohol is a central nervous system depressant, and using it to manage anxiety or insomnia makes both worse in the medium term. Sleep problems, which are particularly common, are also one of the best-identified relapse factors.
What becomes possible again when you stop
We will not end this article on a list of risks, because that is not the most useful message.
A large share of these harms regresses or stabilises after stopping. Fatty liver improves within a few weeks. Blood pressure falls within two to four weeks. Sleep problems settle down over a few months. Cognitive functions recover partially, sometimes substantially, after a prolonged period without alcohol [3]. The risk of cancer, for its part, decreases gradually the longer you stay alcohol-free.
None of these changes happens on command: they take time and support. Our article on the benefits of quitting alcohol day by day sets out the timeline, and the one on the signs of alcoholism helps you assess your drinking.
One precaution before any change: if you drink every day, stopping abruptly can carry a medical risk. Talk to your GP before you stop.
Reset Laser support
The laser auricular reflexology offered in our centres targets the physical side of the urge to drink: a session of about one hour, stimulating reflex points on the ear with a soft low-intensity laser, without medication. It comes with 12 months of personalised support and a free support session if you relapse. This commercial commitment is an obligation of means and cannot be considered a promise of results, as success also depends on your personal willpower. It complements medical follow-up and never replaces it.

OUR EXPERT’S ADVICE
Bruno Couderc — Practitioner in auricular reflexology and support coaching
« An article like this one produces a spike of worry that fades within a week. That is almost always what happens, and it is why nothing changes. If something in this list made you stop and think, turn it straight away into an action with a date: an appointment with your GP, a blood test, or simply writing down for seven days what you actually drink. Just one, chosen now. Almost all the clients I support who made a change started with a step like this, not with a grand decision. »
Frequently asked questions
What is the most common disease caused by alcohol?
Liver damage is the most frequent, starting with steatosis, which is reversible. In terms of deaths, cancers come first, with 16,000 attributable deaths a year in France [1].
What can alcohol cause?
Liver damage, several types of cancer, high blood pressure and heart rhythm disorders, brain and cognitive damage, pancreatitis, as well as sleep and mood disorders [1][2][3][4].
At what amount does alcohol become dangerous?
In France, the guidelines set a maximum of 10 drinks a week and 2 a day, with some alcohol-free days. For cancer risk, no threshold is protective: the risk rises even at low levels of drinking [2].
Are alcohol-related diseases reversible?
Partly, and it depends on the stage. Fatty liver, high blood pressure and sleep problems improve markedly once you stop. Established cirrhosis and Korsakoff syndrome leave lasting damage.
