Bloating, a feeling of fullness and tightness in the abdomen, is an extremely common complaint that plagues many people's daily lives. Although it is often harmless, persistent or recurrent bloating can have a significant impact on quality of life and may even be a symptom of a serious digestive disorder. In this article, we explain in detail what may be behind bloating, how lifestyle changes can help alleviate it, and what diagnostic and therapeutic options are available to treat the problem. Endomedix Gastroenterology Centre with the help of experts.
What exactly is bloating and what are its symptoms?
Bloating is a subjective sensation: a feeling of fullness or pressure in the abdomen, often accompanied by visible abdominal distension, also known as distension. It is important to distinguish between the two, as a feeling of fullness is not always associated with an increase in abdominal volume. Bloating is often associated with other symptoms such as:
- Excessive gas formation and intestinal gas (flatulence)
- Abdominal pain or discomfort
- Abdominal cramps
- Changes in bowel movements (diarrhoea or constipation)
- Burp
- Early feeling of fullness during meals
Together, these symptoms may indicate that there is a problem with the digestive system.
The most common causes of bloating
Bloating can be caused by many factors, from simple lifestyle habits to complex digestive diseases.
Lifestyle factors and diet
The most common cause of bloating is often our diet and lifestyle.
- Air aspiration (aerophagia): Excessive air swallowing, which can occur when eating or drinking, chewing gum, smoking or even under stress, leads to an increase in the amount of air entering the stomach.
- Eating gas-forming foods: During the digestion of certain foods, intestinal bacteria produce increased amounts of gas. Examples include legumes (beans, lentils), cabbage (broccoli, cauliflower), onions, carbonated drinks and artificial sweeteners.
- High fat foods: Fatty foods slow down the emptying of the stomach, which can lead to a feeling of fullness and bloating.
- Grate coating: Although fibre intake is essential for healthy digestion, sudden increases in fibre intake or consumption of inappropriate (e.g. insoluble) fibre can worsen symptoms.
Digestive diseases
If the bloating persists and is accompanied by other symptoms, it is important to seek medical advice, as there may be more serious underlying conditions.
- Irritable bowel syndrome (IBS): IBS is one of the most common functional bowel diseases, with abdominal pain, bloating and altered bowel movements being the leading symptoms. The intestinal tract of patients with IBS is often hypersensitive, causing even normal amounts of bowel gas to be experienced as uncomfortable straining.
- Food intolerances:
- Lactose intolerance: Lack of lactase enzyme needed to digest milk sugar (lactose). Once in the colon, lactose ferments, causing gas, bloating and diarrhoea.
- Fructose malt absorption: Fructose (fructose) malabsorption can produce similar symptoms.
- Contaminated small bowel syndrome (SIBO): In this condition, the bacteria normally present in the large intestine multiply in large numbers in the small intestine. These bacteria ferment ingested carbohydrates already in the small intestine, leading to significant gas formation and bloating.
- Coeliac disease (celiac disease): An autoimmune disease triggered by gluten (a protein found in wheat, barley and rye) that leads to damage to the lining of the small intestine. Typical symptoms include bloating, diarrhoea, abdominal pain and malabsorption.
- Functional dyspepsia: A condition with pain or discomfort in the upper part of the stomach, with symptoms of feeling full after meals, early satiety and bloating, without any organ lesions.
- Gastric motility disorders (e.g. gastroparesis): A slowing of gastric emptying, which causes food to stay in the stomach too long, causing a feeling of fullness and bloating.
- Inflammatory bowel diseases (IBD): Crohn's disease and ulcerative colitis are chronic inflammatory conditions that can also cause bloating, although abdominal pain, bloody diarrhoea and weight loss are the more dominant symptoms.
How can we relieve bloating? Lifestyle and dietary advice
Before seeking medical help, it's worth trying some simple lifestyle and dietary changes that can often be effective in alleviating symptoms.
- Conscious eating: Eat slowly, chew your food thoroughly and avoid swallowing air. Do not talk while eating.
- Smaller, more frequent meals: Large portions can put a strain on the digestive system. Try to eat smaller portions five to six times a day.
- Avoiding gas-forming foods: Keep a food diary to identify the foods that make your symptoms worse. Avoid or reduce your intake of pulses, cabbage, onions, fizzy drinks and chewing gum.
- Low FODMAP diet: FODMAPs (fermentable oligo-, di-, mono- and monosaccharides and polyols) are short-chain carbohydrates that are difficult for some people to absorb and cause gas and bloating when fermented in the gut. The diet consists of temporarily avoiding foods high in FODMAPs (e.g. certain fruits, vegetables, dairy products, cereals) and then gradually reintroducing them to establish personal tolerance. This diet is recommended under the supervision of a dietician.
- Fluid consumption: Drink enough water, but only in moderation between meals so as not to dilute stomach acid. Avoid fizzy drinks.
- Regular physical activity: Moderate-intensity exercise, such as a brisk walk, stimulates bowel movements and can help to expel gas, reducing bloating.
- Probiotics: In some cases, probiotics containing beneficial bacteria can help restore the balance of the gut flora and relieve bloating. Ask your doctor or pharmacist for advice on the right product for you.
When should we see a doctor?
Although bloating is often harmless, in some cases a gastroenterological examination is essential. Consult a specialist if you have bloating:
- Persistent or recurrent.
- Severe pain or cramping.
- It is associated with „alarming” symptoms such as unintentional weight loss, bloody stools, fever or difficulty swallowing.
- It significantly reduces the quality of life.
From Endomedix Gastroenterology Centre experienced specialists are ready to investigate the cause of your complaints thoroughly.
Diagnosis of bloating in Endomedix Centres
To make an accurate diagnosis, the specialist will take a detailed medical history, including eating habits, lifestyle and accompanying symptoms. This is followed by a physical examination. Depending on the underlying cause, further investigations may be necessary:
- Laboratory tests: A blood test can help rule out inflammatory processes, anaemia and coeliac disease (by testing for specific antibodies).
- Stool analysis: It can detect hidden bleeding, inflammatory markers (e.g. calprotectin) and possible infections.
- Exhalation tests: These non-invasive tests are essential for the diagnosis of lactose intolerance, fructose intolerance and SIBO. The patient consumes a special sugar solution (lactose, fructose or lactulose) and then blows into a device at set intervals, which measures the concentration of exhaled hydrogen and methane gas. Elevated values indicate malabsorption or bacterial overgrowth.
- Endoscopic examinations (reflections):
- Gastroscopy (gastroscopy): It allows examination of the upper part of the oesophagus, stomach and small intestine. It can be used to diagnose coeliac disease (by histological sampling), reflux disease or gastric emptying disorders.
- Colonoscopy (colonoscopy): It is used to examine the entire colon, excluding inflammatory bowel diseases or tumour lesions.
- Imaging studies: Abdominal ultrasound, CT or MR scans may be needed less frequently, in specific cases, to assess the condition of the abdominal organs.
Modern therapeutic options
The treatment always depends on the underlying disease diagnosed. The Endomedix Gastroenterology Centre offers the most modern, personalised therapy options:
- Managing IBS: Diet (e.g. low FODMAP diet with the help of a dietician) and lifestyle counselling are the cornerstones of therapy. If necessary, antispasmodics, bowel motility drugs and specific antibiotics (e.g. rifaximin) that act on IBS symptoms can be used to improve bloating and global symptoms.
- Managing SIBO: The aim of the therapy is to reduce the number of bacteria that have multiplied in the small intestine. This is done with special antibiotics (e.g. rifaximin) that are minimally absorbed. Following treatment, restoring the balance of the gut flora and addressing the underlying causes (e.g. motility disorder) is essential to prevent recurrence.
- Management of food intolerances: Therapy is based on avoidance of the carbohydrate (lactose, fructose) that is causing the problem. In the case of lactose intolerance, supplementation with lactase enzyme in the form of tablets is also possible.
- Management of coeliac disease: The only effective therapy is a strict, lifelong gluten-free diet.
- Treatment of functional dyspepsia and motility disorders: In addition to dietary advice, anti-ulcer (prokinetic) medicines and medicines that improve the stomach's capacity to absorb food (e.g. buspirone) can help.
