Is My Bloating Normal, or Should I Get It Checked?
If you’ve ever undone the top button of your trousers after lunch, you’re in good company. Bloating is one of the most common digestive complaints there is, and most of the time it settles on its own within a day or two.
But if it’s been sticking around for weeks, or it’s starting to feel like your new normal, it’s worth understanding why, and when it’s time to get it looked at properly.
WHAT IS BLOATING?
Bloating is that tight, full feeling in your tummy, sometimes with visible swelling, sometimes without. It usually comes down to gas, digestion, or fluid building up in your gut. It’s not a condition in itself. It’s a symptom, and it can have a lot of different causes, from what you ate for lunch to how your gut is working day to day.
WHAT ARE THE MOST COMMON CAUSES OF BLOATING?
For most people, bloating is linked to something everyday:
- Eating too fast, or eating a large meal
- Fizzy drinks, or drinking through a straw
- Certain foods, like beans, onions, and cabbage
- Constipation
- Stress
These are all things you can usually manage yourself, and for a lot of people, small changes to how and what you eat make a real difference.
Getting a proper diagnosis usually starts with simple, non-invasive tests, and once we know what we’re dealing with, we can actually do something about it.”
Why does my bloating keep coming back?
Sometimes bloating isn’t a one-off. It’s there most days, it’s part of a wider pattern, and simple dietary changes don’t seem to make a difference. When that’s the case, it’s worth getting checked rather than continuing to manage the symptom on its own, as your bloating could be a sign of one of the conditions below.
Coeliac disease and food intolerances
For some people, bloating is your gut’s reaction to something specific in your diet, particularly if your gut tends to ferment certain foods more than most. Coeliac disease is a common auto-immune condition, that is seen in 1% of the UK population. The condition reacts to gluten and is frequently seen in association with other intolerances like lactose and carbohydrate sensitivities. These can all cause ongoing bloating that won’t shift with general diet tweaks, because the trigger is more specific.
Hormonal changes
If you have periods, or you’re going through perimenopause or menopause, bloating can be linked to shifting hormone levels affecting your gut motility (how quickly food moves through your digestive system), rather than digestion itself. It’s a fairly common symptom that’s often overlooked or dismissed as “just hormones,” but it’s still worth understanding and, if it’s disruptive, worth getting support for. Whilst our Gastroenterologists can help if this is a gut motility issue, our Gynaecology experts can help support you with hormonal changes.
IBS and IBD
Conditions like irritable bowel syndrome and inflammatory bowel disease often cause bloating that’s frequent and frustrating, alongside other changes to your gut that come and go over time. Bloating is just part of the picture, and the experts at our Digestive Health Centre can help identify what’s going on with the aim of helping alleviate your discomfort. IBS and IBD aren’t mutually exclusive, in fact they’re seen together in 40-80% of patients. In IBS, bloating often indicates trapped gas, but in IBD, it can sometimes point to a narrowing or blockage in the bowel, which is a more serious issue.
Acid reflux
Bloating and reflux often go hand in hand. When stomach acid travels back up into your oesophagus, it’s not unusual for that to come with a bloated, uncomfortable feeling too, especially after eating. If heartburn, a sour taste, or discomfort after meals sound familiar alongside the bloating, it’s worth reading our guide to acid reflux to understand the overlap and what tends to help.
These symptoms are sometimes linked to a build-up of stool in the bowel, known clinically as faecal loading, and constipation. When these are the underlying cause, treating it directly can settle both the reflux and the bloating quickly, rather than reaching for stronger and larger doses of antacids that aren’t tackling the actual cause.
How long is bloating normal for?
Most bloating isn’t a sign of anything serious. But duration matters here more than it does with a lot of other symptoms.
As a general guide, if bloating is happening most days for three weeks or more, it’s worth getting checked. This is the same benchmark used in national NHS health guidance, and it exists because persistent bloating can, in rare cases, be an early sign of something that needs attention, including ovarian, bowel, or kidney conditions.
What else should I look out for?
It’s worth getting checked sooner if:
- You’re also experiencing unexplained weight loss
- There’s been an on-going change in your bowel habits
- You’re experiencing persistent pain
- You’ve noticed blood in your stool
- You’ve noticed new bloating that wasn’t there before, especially if you’re over 50
How is persistent bloating diagnosed and treated?
If you’ve been living with bloating for more than a few weeks and it’s not settling, the next step isn’t complicated. A consultation with a gastroenterologist usually starts with understanding your pattern of symptoms, and some straightforward tests, such as blood tests, stool tests or food intolerance testing, before anything more involved.
Our Digestive Health Centre brings together consultation and diagnostics in one place, so if further investigation is needed, it can happen quickly. Depending on your symptoms, this might include a colonic transit study (a series of x-rays that tracks how food moves through your gut over the course of about a week), a gastroscopy, colonoscopy, or capsule endoscopy. We offer a range of diagnostic gastro Fixed Price Packages covering these and other procedures, so you’ll know exactly what’s included and what it costs from the outset.
