Abdominal bloating and flatulence (meteorism) are among the most common complaints that lead patients to consult a gastroenterologist. Although in most cases the underlying cause is a dietary error or lifestyle factor, persistent bloating can also be a symptom accompanying more serious digestive disorders. The Endomedix Gastroenterology Centre In this article, experts help you understand the possible causes of bloating and highlight when you should not delay seeing a specialist any longer.
What causes bloating?
The sensation of bloating is caused by an excessive amount of gas accumulating in the digestive system. This gas can enter the body in two ways: either we swallow air whilst eating or talking (aerophagia), or it is produced by gut bacteria as they break down nutrients.
The most common causes are:
- Dietary factors: Certain foods (beans, lentils, brassicas, fizzy drinks) naturally increase gas production. Eating too quickly or chewing gum, on the other hand, leads to swallowing unnecessary air.
- Food intolerances: One of the main symptoms of lactose intolerance (sensitivity to milk sugar) or fructose malabsorption (impaired absorption of fruit sugar) is pronounced bloating, which occurs immediately after eating the food in question.
- An imbalance in the gut flora (dysbiosis): If the number of beneficial bacteria in our gut decreases and gas-producing bacteria become predominant, a feeling of bloating may become a persistent problem.
- SIBO (Small Intestinal Bacterial Overgrowth): In such cases, bacteria from the large intestine migrate into the small intestine, where they begin to ferment the food prematurely, leading to extremely severe bloating and distension.
- IBS (Irritable Bowel Syndrome): A functional disorder of bowel function in which the sensitivity of the bowel wall is heightened, meaning that even a normal amount of gas is experienced by the patient as painful bloating.
When does bloating become a medical condition?
Many people try to remedy the problem with over-the-counter medicines (e.g. preparations containing simethicone), but these often only serve to mask the symptoms. In 2025, in this age of modern diagnostics, you do not have to put up with these complaints.
Consult a specialist if your bloating:
- It recurs regularly or becomes chronic (lasting for more than 2–3 weeks).
- It is accompanied by severe abdominal pain or cramps.
- It is clearly linked to the consumption of certain foods.
- It is associated with a change in bowel habits (diarrhoea or constipation).
„Alarming” symptoms (requiring immediate medical attention!):
There are certain symptoms where bloating may be caused by a more serious underlying condition, such as inflammatory bowel disease or a tumour:
- Unintentional, sudden weight loss.
- Blood in the stools.
- Anaemia, constant tiredness.
- Fever or night sweats.
- A lump or hard area felt when palpating the abdomen.
How does the examination take place at Endomedix?
From At the Endomedix Gastroenterology Centre We do not merely treat the symptoms; we seek to identify the underlying cause. Our range of diagnostic services includes the very latest techniques:
- Exhalation tests (H₂ test): This is the simplest and quickest method for detecting lactose intolerance, fructose malabsorption and SIBO. It is painless and extremely accurate.
- Laboratory tests: We use a blood test to check for inflammatory markers, coeliac-specific antibodies and liver function.
- Abdominal ultrasound: It helps to rule out gallstones, pancreatic involvement or other organ abnormalities.
- Colonoscopy: If inflammatory bowel disease or a tumour is suspected, this is the most reliable method. At Endomedix, you can request to have the examination carried out under general anaesthesia, making it completely stress-free and painless.
What can you do to relieve your symptoms?
As well as undergoing a medical examination, it is worth following some lifestyle advice:
- Keep a food diary to spot the patterns!
- Eat slowly and chew your food thoroughly!
- Avoid fizzy drinks and artificial sweeteners (e.g. sorbitol)!
- Make sure you exercise regularly; physical activity helps to relieve flatulence.
