Why your stomach feels bloated, simple ways to ease it, common trigger foods with gentler swaps, and the warning signs that mean you should see a doctor.
A bloated stomach is usually caused by trapped gas, eating too quickly, fizzy drinks, constipation or foods your gut finds harder to digest, such as beans, onion or wheat. Most bloating is harmless and eases with simple changes like eating slowly, having smaller meals and taking a gentle walk, but bloating that keeps coming back needs checking.
Bloating is one of the most common gut complaints, and it can make you feel uncomfortable, self-conscious and tired. This guide explains the main bloating causes, how to reduce bloating, which foods cause bloating and what to swap them for, and the warning signs that mean you should see a doctor.
What is bloating, and how is it different from distension?
Bloating is the feeling of fullness, tightness or pressure in your tummy, often with wind or rumbling. Distension is a visible increase in the size of your abdomen, so your clothes may feel tighter by the evening. You can have one without the other, and both often come and go through the day.
For most people, bloating is linked to gas building up in the gut, a gut that is extra sensitive to normal amounts of gas, or food and stool moving slowly through the bowel.
What causes a bloated stomach? Common bloating causes
Most of the time, bloating comes down to everyday habits and foods. Common causes include:
- Eating quickly or swallowing air: eating fast, talking while you eat, chewing gum and drinking through a straw all add air to your stomach.
- Fizzy drinks: carbonated drinks release gas into the stomach.
- Large or fatty meals: rich meals take longer to leave the stomach, which can leave you feeling full and uncomfortable.
- Constipation: when stool builds up, your tummy can feel heavy and bloated.
- Increasing fibre too quickly: fibre is good for you, but a sudden jump can cause wind and bloating while your gut adjusts.
- Sugar alcohols: sweeteners such as sorbitol, mannitol and xylitol, found in many sugar-free sweets and chewing gums, can cause gas and loose stools.
- Lactose intolerance: some people do not make enough lactase, the enzyme that digests milk sugar, so milk can cause bloating, wind and diarrhoea.
- High-FODMAP foods: FODMAPs are types of carbohydrate that gut bacteria ferment, producing gas. Onion, garlic, wheat, beans and lentils, and some fruits such as apples, pears and mango are common examples.
- Your menstrual cycle: hormone changes before and during a period often cause bloating.
- IBS (irritable bowel syndrome): bloating is one of the main symptoms of IBS, along with tummy pain and changes in bowel habit.
Less commonly, bloating can be a sign of a condition such as coeliac disease or, rarely, something more serious. That is why the red flags further down this page matter.
How to reduce bloating: practical relief tips
Small, consistent changes often make the biggest difference. Try these:
- Eat slowly and chew well. Put your spoon or fork down between bites and give yourself time to finish a meal.
- Have smaller, more regular meals rather than one or two very large ones.
- Take a gentle walk after meals. Movement helps gas pass through your gut.
- Increase fibre gradually and drink water with it. Add one higher-fibre food at a time over a few weeks, and drink plenty of fluid through the day.
- Cut back on fizzy drinks, chewing gum and sugar-free sweets.
- Try peppermint tea or ginger. Many people find these soothing after meals. They are traditional comforts and the evidence for bloating is limited, but they are fine for most people in normal food amounts. Peppermint can make heartburn worse in some people.
- Keep a food and symptom diary for two to three weeks. Note what you eat, when bloating happens, your bowel movements, stress levels and, for women, where you are in your cycle. Patterns are often easier to spot on paper.
If you are not opening your bowels regularly, treating constipation often eases bloating too. Our guide to the diet for constipation explains which foods and drinks help.
Foods that cause bloating and gentler swaps
The table below lists common triggers and kinder alternatives. Not everyone reacts to the same foods, so use it as a starting point rather than a list of foods to avoid forever.
| Common trigger | Why it can bloat | Gentler swap |
|---|---|---|
| Chickpeas, rajma and other beans | Contain fermentable carbohydrates (FODMAPs) | Soak well, rinse and cook thoroughly, and have smaller portions; or try moong dal |
| Fizzy drinks and soda | Release gas into the stomach | Water, mint-infused water or plain laban |
| Onion-heavy curries and garlicky dishes | Onion and garlic are high in FODMAPs | Use less onion; flavour with cumin, ginger, fresh coriander, garlic-infused oil or the green tops of spring onions |
| Sugar-free sweets and gum | Sugar alcohols such as sorbitol ferment in the gut | A small portion of a regular sweet, or a piece of fruit |
| Milk, if you are lactose intolerant | Lactose is not fully digested | Lactose-free milk, or yoghurt and laban, which many people with lactose intolerance tolerate better in moderate amounts |
| Large, rich meals such as biryani or fried snacks | Fat slows down stomach emptying | Smaller portions with plenty of vegetables; grilled rather than fried |
| Wheat-based foods, for some people | Wheat contains fructans, a type of FODMAP | Rice, oats or potatoes at some meals |
| Apples, pears, mango and watermelon | Contain fructose or sugar alcohols | Oranges, kiwi, grapes, pineapple or strawberries |
Is a low-FODMAP diet right for me?
The low-FODMAP diet is a well-researched approach for managing IBS symptoms, including bloating. It is a short-term, step-by-step process that works best with guidance from a dietitian or nutrition professional:
- Elimination: for a short period, usually a few weeks, you cut down on high-FODMAP foods to see whether your symptoms settle.
- Reintroduction: you bring back one FODMAP group at a time to learn which ones, and how much, trigger your symptoms.
- Personalisation: you return to the widest, most varied diet you can, limiting only the foods that truly cause problems.
It is not meant to be a forever diet. Staying very restrictive for a long time can reduce the variety of your diet and may affect the balance of your gut bacteria. Before you start, see your doctor to rule out conditions such as coeliac disease. Coeliac testing only works while you are still eating gluten, so do not cut out wheat before you have been tested.
When to see a doctor
Occasional bloating is normal. See your doctor promptly if you have:
- bloating most days for 3 weeks or more
- weight loss you cannot explain
- blood in your stool, or black, tarry stools
- a change in your bowel habit that does not settle
- difficulty swallowing
- vomiting that keeps happening
- a lump in your tummy
- persistent bloating with feeling full quickly or loss of appetite, especially if you are a woman over 50, as this should be checked
- signs of anaemia, such as unusual tiredness, breathlessness or pale skin
- a family history of bowel cancer, ovarian cancer or coeliac disease
Get urgent medical help if bloating comes with severe tummy pain, a hard and swollen abdomen, being unable to pass stool or wind, or a high temperature.
Frequently asked questions
Why is my stomach bloated every day?
Daily bloating is often linked to eating habits, constipation, IBS or particular trigger foods. However, if you have been bloated most days for three weeks or more, see your doctor to rule out other causes.
What gets rid of bloating fast?
A gentle walk, loosening tight clothing, a warm drink such as peppermint or ginger tea, and avoiding fizzy drinks can help gas move along. If bloating is severe or comes with pain, vomiting or fever, get medical advice.
Can stress cause bloating?
Yes. Your gut and brain are closely connected, and stress can make the gut more sensitive and change how it moves, especially if you have IBS. Relaxation techniques, regular sleep and physical activity can all help.
Do probiotics help with bloating?
Some people with IBS find that certain probiotics help, but results vary and the evidence is mixed. If you try one, give it a few weeks and stop if you notice no difference, and check with your doctor first if you have a weakened immune system.
