Bloating

Relevant specialty: General Internal Medicine (GP) · Gastroenterology

Bloating occurs when gas accumulates increasingly in the intestine, and manifests as a feeling of tension, a feeling of fullness, or frequent passing of wind. It is very common and usually harmless. It is often related to diet or a sensitive gut.

Possible causes

01

Gas-producing foods

Legumes, cabbage, onions, or carbonated drinks promote gas formation in the intestines. Foods high in sugar can also contribute to this.

02

Eating habits

Eating hastily, talking while eating, or chewing gum allow more air to enter the digestive tract. This increases the feeling of fullness.

03

Sensitive digestive system and intolerances

With irritable bowel syndrome or intolerances such as lactose intolerance, the intestines react more sensitively. This can lead to increased bloating.

Typical steps at the doctor's office

  1. 1During the consultation, your diet, eating habits, and the connection with certain foods will be discussed.
  2. 2Your abdomen will be examined to assess the symptoms and evaluate bowel activity.
  3. 3If an intolerance is suspected, a targeted investigation, such as with a food diary or test, may be useful.

What you can do yourself

  • Observe which foods trigger the symptoms and reduce these if necessary.
  • Eat slowly, chew well, and avoid swallowing air hastily.
  • Avoid carbonated drinks and highly gas-producing foods if they are poorly tolerated.
  • Regular exercise and a warm abdominal compress can support well-being.
When a doctor's visit makes sense

If bloating occurs very frequently, is accompanied by pain, or if bowel habits change permanently, it is worth getting an assessment from your GP or in gastroenterology. Medical advice is also advisable if the symptoms affect your daily life.
