Gas is a normal part of digestion, but if you often feel gassy or bloated, it may be worth trying to understand what is causing it. Start with simple changes such as eating more slowly, limiting carbonated drinks, observing which foods trigger symptoms, increasing fibre gradually, drinking regularly and staying active. If your symptoms keep coming back or affect your everyday life, there may be other underlying factors, such as constipation, IBS, food intolerance or SIBO. Gas alone, however, is not enough to establish a specific cause. This is where a SIBO test, such as the Four-in-One Test, may be a next step to gain more clarity about possible causes. The most important thing is therefore not to eliminate as many foods as possible, but to understand which factors actually affect your digestion.
Do you often experience gas, a bloated stomach or a feeling of tightness in your abdomen? Gas in the digestive tract is very common and can occur when we swallow air or when bacteria in the large intestine break down carbohydrates that have not been fully digested.
For some people, symptoms are related to what they eat or drink. For others, constipation, food intolerance, IBS (often caused by SIBO; an overgrowth of bacteria in the small intestine) or other gastrointestinal conditions may play a role.
There is therefore no single solution that works for everyone. Here are 10 simple tips that may help reduce gas and help you understand what affects your own digestion.
10 Tips to Reduce Gas
# | Try this | Why it may help |
1 | Limit carbonated drinks | Carbonated drinks may contribute to more gas and bloating. |
2 | Eat slowly | Eating quickly can cause you to swallow more air, which may increase gas symptoms. |
3 | Pay attention to sugar alcohols | Sorbitol, xylitol and other sugar alcohols can cause gas in sensitive people. |
4 | Drink regularly | Getting enough fluids is important for normal bowel function and may be particularly relevant if you experience constipation. |
5 | Observe foods that trigger symptoms | Certain carbohydrates, legumes, vegetables and dairy products may cause more gas in some people. |
6 | Increase fibre gradually | A rapid increase in fibre intake can cause more gas and bloating. |
7 | Be cautious with supplements | Natural products are not automatically suitable for everyone and can affect the digestive system differently. |
8 | Manage stress | Stress can affect communication between the brain and gut and make digestive symptoms more noticeable. |
9 | Stay active | Regular physical activity can support normal bowel function and may feel good when you are bloated. |
10 | Track your symptoms | A simple food and symptom diary can help you identify recurring patterns. |
1. Limit Carbonated Drinks
Soft drinks, sparkling water and other carbonated drinks contain carbon dioxide. For some people, carbonated drinks may contribute to more burping, gas or a feeling of bloating.
If you often feel gassy, you can try reducing the amount of carbonated drinks for a period of time and see whether it makes a difference.
You do not automatically need to avoid them completely if you do not notice that they affect you.
2. Eat Slowly and Chew Thoroughly
Some gas comes from air that we swallow when we eat and drink.
You may swallow more air if you:
- Eat very quickly
- Drink through a straw
- Chew gum
- Talk a lot while eating
- Drink a lot of carbonated beverages
Eating more slowly and sitting down calmly while you eat can therefore be a simple way to reduce the amount of air you swallow.
3. Pay Attention to Sugar Alcohols
Sugar alcohols are often used in sugar-free products, chewing gum and sweets.
Examples include:
- Sorbitol
- Xylitol
- Mannitol
- Maltitol
- Erythritol
Some of these carbohydrates can be difficult to absorb and may contribute to gas and bloating in sensitive people.
If you often experience gas, it may therefore be worth checking the ingredient list on sugar-free products and seeing whether you notice a connection.
4. Drink Regularly
Getting enough fluids is important for normal body function and may be particularly relevant if you also experience constipation.
Constipation can contribute to bloating and gas, so it can be helpful to make sure you get enough fluids throughout the day.
There is no exact number of glasses that is right for everyone. Fluid needs vary depending on factors such as physical activity, temperature and diet.
5. Observe Which Foods Trigger Your Symptoms
Some foods may cause more gas in certain people.
Examples include:
Group | Examples |
Legumes | Beans, lentils, peas |
Certain vegetables | Broccoli, cauliflower and other cruciferous vegetables |
Certain fruits | Apples, pears and peaches |
Dairy products | Milk, ice cream and yoghurt in people who react to lactose |
Certain sweeteners | Sorbitol, xylitol and other sugar alcohols |
This does not mean that you need to avoid these foods. The important thing is to see whether they actually cause more symptoms for you.
6. Increase Fibre Gradually
Fibre is an important part of a varied and balanced diet, but a rapid increase in fibre intake can cause more gas and bloating.
If you want to eat more fibre-rich foods, it may therefore be better to increase the amount gradually and give your digestive system time to adjust.
This may be particularly relevant if you have recently started eating much more whole grains, legumes, fruit or vegetables.
However, if your symptoms are related to IBS (research has shown that up to 85% of people with IBS had SIBO), increasing fibre intake may worsen gas symptoms because fibre supports bacteria in the small intestine. In these cases, a SIBO test such as the Four-in-One Test can be used to gain more clarity about possible causes of gas production.
7. Be Cautious with Supplements
If you often experience gas, it can be tempting to try different supplements or herbal products.
But natural does not automatically mean that something is suitable for everyone.
Different products can affect the digestive system in different ways, and some supplements can also interact with medications.
If you want to try a supplement, it is therefore sensible to introduce one product at a time and observe how you respond. Talk to your healthcare provider if you take medication or have a medical condition.
8. Manage Stress and Give Your Gut Time to Recover
The gut and brain are constantly communicating through the gut-brain axis.
Stress can affect how the gastrointestinal tract functions and, for some people, make bloating, stomach pain or other symptoms more noticeable. Functional gastrointestinal conditions such as IBS are also linked to how the brain and gut interact.
You can try:
- Yoga
- Deep breathing
- A gentle walk
- Regular breaks and enough sleep
The goal is not to eliminate all stress, but to find ways to give your body regular opportunities to recover.
9. Stay Active
Regular physical activity can support normal bowel function and may also feel good when you already feel bloated.
You do not need to exercise intensely. Try, for example:
- Going for a walk
- Gentle yoga
- Cycling
- Any other movement you enjoy
If your stomach feels heavy after a meal, a gentle walk can be a simple option.
10. Track Your Symptoms
If your gas keeps coming back, it can be difficult to see what is actually triggering it.
For a period of time, try writing down:
What you ate → what you drank → when the symptoms appeared → which symptoms you experienced → how long they lasted.
A simple diary can make it easier to identify recurring patterns. A healthcare professional or dietitian can also use this information to assess whether certain foods or eating habits may be relevant.
Why Do You Get Gas?
Gas in the gastrointestinal tract is normal. Gas is produced, among other things, when bacteria in the large intestine break down carbohydrates that have not been fully digested.
We also swallow air when we eat and drink.
Increased gas symptoms may therefore be related to:
- Food and drinks
- Swallowing a lot of air
- Constipation
- Lactose or fructose intolerance
- IBS and other functional gastrointestinal conditions
- SIBO
- Other gastrointestinal conditions
Having gas does not automatically mean that something is wrong. What matters is whether the symptoms are recurring, severe or affecting your everyday life.
Can SIBO Cause Gas?
Yes, SIBO can be one of several possible causes of gas symptoms.
These bacteria can produce additional gas, and SIBO may occur together with symptoms such as:
- Bloating
- Gas
- Diarrhea
- Weight loss
- Changes in bowel habits
However, the same symptoms can occur with many other gastrointestinal conditions.
Gas and bloating alone are therefore not enough to establish SIBO.
If you have recurring or persistent symptoms, it may be relevant to talk to a healthcare professional about possible causes and whether further investigation is needed.
Can a Low-FODMAP Diet Help with Gas?
A low-FODMAP diet limits certain fermentable carbohydrates that may contribute to gas production and other symptoms in sensitive people.
It is used, among other things, as a symptom-management tool for IBS.
However, it is not necessary to start a strict low-FODMAP diet as soon as you experience gas.
A better first step may be to:
- Observe which foods seem to trigger your symptoms.
- Make small changes.
- Keep a food and symptom diary.
- Get help from a dietitian if you need to make larger dietary changes.
What Can You Do for Gas Quickly?
If you feel gassy right now, you can try a few simple things:
- Take a gentle walk
Light movement may feel good when your stomach is bloated. - Drink water
Especially if you also tend to experience constipation. - Avoid carbonated drinks for the moment
This may reduce additional gas intake. - Eat calmly
Avoid eating very quickly or swallowing a lot of air. - Slow down and relax
Stress can make some digestive symptoms more noticeable.
There is no method that works for everyone. What helps depends on why you are experiencing gas.
When Should You Seek Medical Care for Gas?
Gas is common, but recurring or troublesome symptoms may need to be investigated.
Contact a healthcare professional if:
- Gas or bloating occurs frequently.
- Your symptoms affect your everyday life.
- Your symptoms suddenly change.
- You also experience abdominal pain, diarrhea or constipation.
- You lose weight without trying.
Seek medical care more promptly if you experience severe or sudden abdominal pain, vomiting, fever or other significant general symptoms.
