Bloating after quitting alcohol: why it happens and what helps

Why your stomach can feel bloated after you stop drinking, why your face and belly may look less puffy, what helps, and when bloating needs a doctor.

Quick answer

The NHS says the most common reason for bloating is a lot of gas in your gut. After you stop drinking, things that often change can add to it: more fizzy drinks in place of alcohol, more sugar, bigger meals, more fibre at once, and constipation while your bowels settle. Alcohol also affects the stomach and gut directly, and that may take time to settle. The puffy look that alcohol can give your face is a separate thing: Drinkaware says many of alcohol's effects on your appearance are reversible when you drink less. See a GP if you feel bloated regularly, or have bloating with weight loss or blood in your poo.

Why you might feel bloated after quitting alcohol

No study has measured bloating in people who have just stopped drinking, so nobody can say how common it is. But the NHS's list of causes, and what research shows about alcohol and the gut, explain why it happens to many people.

Fizzy drinks in place of alcohol. Many people swap beer or wine for cola, sparkling water or alcohol-free beer. The NHS advice for bloating is not to drink lots of fizzy drinks or caffeine, so a fridge full of fizzy drinks can leave you more bloated than before, not less.

More sugar and bigger meals. Sugar cravings are common in the first weeks, and the NHS lists lots of processed, sugary or fatty food, and large meals late at night, among the things that make bloating worse. Our guide to sugar cravings after quitting alcohol explains why the cravings happen.

More fibre all at once. Eating healthier is a good idea, but beans, lentils and cabbage are foods the NHS says are known to cause gas. Adding a lot of them in one go can bring on wind and bloating.

Constipation. Constipation is one of the digestion problems the NHS lists as a cause of bloating, and it is common in the first weeks without alcohol. Our guide to constipation after quitting alcohol covers it in detail.

Your gut is settling. Alcohol affects the stomach's acid and the muscles around it, and the movement of the intestines, according to a review of the research. Studies of people who drank heavily for a long time found more bacteria in the small intestine than in people who did not, and in one study some people's gut changes were still there after three weeks without alcohol. None of these studies measured bloating, but they suggest the gut may take time to settle.

Why your face and belly may look less puffy

Some people search for the opposite: when does the alcohol bloat go down? Drinkaware says alcohol dehydrates your body every time you drink, and that this can make your skin look "bloated and puffy". It also says many of alcohol's effects on your appearance are reversible if you drink less.

A smaller belly over the following weeks is more likely to be weight. Alcohol has around 7 calories a gram, almost as many as fat. Our guide to weight loss after quitting alcohol explains how much people tend to lose and why some gain instead.

How long does it last?

There is no study that tracks bloating after quitting alcohol. If it comes from what you eat and drink, it usually eases once you change those things. If you feel bloated regularly, or you have changed your diet and still feel bloated, the NHS says see a GP.

What helps

The NHS advice for bloating:

Go easy on fizzy drinks, coffee and tea. Try still water, or flavour it with fruit.
Smaller, more frequent meals instead of large ones, and not a big meal late at night.
Chew with your mouth closed, so you swallow less air, and do not slouch when you eat.
Exercise regularly. The NHS says it improves digestion and can also help when you already feel bloated.
Drink plenty of water, and if you are constipated, eat foods high in soluble fibre, such as oats or linseed.
Massage your stomach from right to left to release trapped wind.
A pharmacist can suggest a medicine such as simeticone for bloating, or a laxative if you are constipated.

Going back to drinking will not help: the NHS lists alcohol among the drinks to avoid when you are bloated. If other things are changing too, our timeline of what happens when you stop drinking shows what else to expect in the first days and weeks.

When to get help

If you drink heavily every day, speak to a doctor or a local alcohol service before you stop. Stopping suddenly when you are dependent on alcohol can be dangerous.

See a GP if you:

feel bloated regularly
have changed your diet but keep feeling bloated
have bloating and have lost weight without trying
have bloating and blood in your poo

Get urgent medical help if you have bloating with vomiting, diarrhoea or constipation, with a stomach ache, with a high temperature, or with a swelling or lump in your tummy, or if you cannot pee, poo or fart.

Get emergency help if your stomach is swollen and you have a severe stomach ache that came on suddenly, you are vomiting blood, or you have severe difficulty breathing.

Questions

Is bloating normal after quitting alcohol?

It is common. Swapping alcohol for fizzy drinks, eating more sugar or bigger meals, adding a lot of fibre at once and constipation are all common in the first weeks, and all are on the NHS's list of things that can cause bloating.

How long does bloating last after quitting alcohol?

No study has measured it. Bloating from food and drink usually eases once you change them. If you keep feeling bloated after changing your diet, see a GP.

Why is my stomach bloated after I stopped drinking?

Most likely a mix of things: more fizzy drinks, sugar or large meals, more fibre at once, and constipation while your bowels settle. Alcohol also affects the stomach and gut, which may take time to settle after you stop.

When does alcohol bloat go away after quitting?

Drinkaware says alcohol dehydrates you every time you drink and can make your skin look bloated and puffy, and that many of these effects are reversible when you drink less. A smaller belly over the following weeks is more likely to be weight loss.
