Can anxiety cause gas and bloating?
Yes. Anxiety changes how you breathe, eat and digest, which can mean more gas and bloating, and the discomfort can feed the anxiety. Here’s what helps.
Anxiety and an uncomfortable, bloated, gassy stomach often go together. If you’ve noticed that your tummy swells up or you’re more gassy when you’re stressed, you’re not imagining it.
How anxiety causes gas and bloating
Swallowing air
When you’re anxious, you tend to breathe faster and through your mouth, sigh more often, and sometimes gulp. You may also eat or drink quickly, chew gum or reach for fizzy drinks. All of these add air to your stomach, which has to come out somewhere: as burping, gas or bloating.
Changes in how your gut moves
Your gut and brain are in constant contact. Stress and anxiety can speed up or slow down how food moves through your gut. When things slow down, food has longer to ferment, which can produce more gas. When they speed up, you may get cramps and diarrhoea.
A more sensitive gut
When you’re anxious, your gut can become more sensitive, so a normal amount of gas feels more uncomfortable and more noticeable.
Changes in eating
Anxiety can change what you eat: skipping meals and then eating a lot at once, reaching for sugary snacks, more coffee, or more alcohol. Any of these can leave you bloated.
Can bloating cause anxiety?
It works both ways. If you’re sensitive to body feelings, a tight, swollen stomach or a gassy cramp can feel alarming. You might worry that something is wrong, or that others will notice, and that worry can then make your gut even more uncomfortable.
What helps
- Breathe slowly through your nose, with a longer out-breath. It calms your gut and means you swallow less air.
- Eat slowly, chew well, and try not to talk while you have food in your mouth.
- Cut back on fizzy drinks, chewing gum and drinking through straws.
- Go for a gentle walk after meals to help things move.
- Notice your trigger foods. Some foods, like beans, onions and some artificial sweeteners, cause more gas for many people. A food and mood diary can help you spot patterns.
- Try a warm drink. Some people find peppermint tea soothing.
- Go easy on caffeine and alcohol.
Could it be IBS?
If you often have bloating, gas, stomach pain, diarrhoea or constipation, it could be irritable bowel syndrome (IBS). The NHS lists stress and anxiety among the possible triggers for IBS flare-ups. A doctor can help you find out, and suggest diet changes and treatments that help.
How Breatheasy can help
Breatheasy can help you calm the anxiety that feeds a bloated, gassy stomach. Its guided breathing exercises pulse your phone as you breathe in, helping you breathe slowly and swallow less air, and ten-second check-ins and a journal help you notice whether symptoms follow stressful days, meals or drinks. If anxiety turns into panic, the panic button walks you through it. Breatheasy is coming soon to iPhone and Android.
When to see a doctor
See a doctor if bloating or gas keeps coming back, or lasts more than a few weeks. Get help urgently if you have:
- weight loss you can’t explain
- bleeding from your bottom, or blood in your poo
- a lump or swelling in your stomach that doesn’t go away
- severe pain, or you keep being sick
These need checking, whatever the cause. If anxiety is behind your symptoms, our post on nervous stomach has more ways to settle it.
