What does bloating feel like?
The NHS describes bloating as a feeling that your tummy is full and uncomfortable. You may notice that your tummy looks or feels bigger than usual, that you have tummy pain or discomfort, that it is rumbling or making noises, or that you are passing more wind than usual.
Common causes of bloating
According to the NHS, the most common reason is having a lot of gas in your gut. This can come from some foods and drinks, such as certain vegetables and fizzy drinks, or from swallowing air as you eat. Bloating can also be linked to a digestive problem such as constipation, a food intolerance or coeliac disease, and some people feel bloated around the time of their period.
What may help
- Move regularly. The NHS says regular exercise can help prevent bloating and can also help when you already feel bloated.
- Look for your triggers. Noting what you eat and drink alongside your symptoms can show patterns. If general diet tips do not help, a GP may refer you to an NHS dietitian.
- Ask a pharmacist. They can advise on medicines that ease bloating.
- Change fibre gradually. Adding fibre too quickly can cause extra wind. Increase it slowly, and drink more fluid as you do.
Fibre and bloating
Fibre is good for your bowel, but sudden increases can cause gas. A Bradford District Care NHS leaflet notes that soluble fibre is more likely to increase gas production than insoluble fibre, so some people feel more bloated when they eat a lot of it. A varied diet and a gradual change usually work best. Our guide to why fibre is important for digestive wellbeing explains both types.
When to get medical advice
The NHS advises you to see a GP if you feel very bloated, you are often bloated or it does not go away. It also says to ask for an urgent GP appointment or call 111 if bloating comes with being sick, diarrhoea, constipation or a stomach ache, and to see a GP if you have bloating together with unintentional weight loss or blood in your poo. Persistent bloating is not usually serious, but the NHS notes that bloating that does not go away can occasionally be a sign of something more serious, which is why it is worth checking.
Where do supplements fit?
No supplement can replace finding out why you are bloated. If bloating is persistent, speak to your GP or pharmacist before trying herbal products, including colon cleanse supplements.
