Irritable Bowel Syndrome

Relevant specialty: Gastroenterology

Irritable bowel syndrome involves recurring abdominal pain, bloating, and changes in bowel habits, without any other underlying disease being found. While the symptoms can be distressing, the condition is benign. Often the complaints persist over a longer period and vary in intensity.

Possible causes

01

Sensitive bowel

The bowel reacts hypersensitively to stretching and normal digestive processes. This leads to pain and altered bowel habits without any pathological findings.

02

Diet and intolerances

Certain foods can worsen symptoms, such as foods that cause bloating or are poorly tolerated. The triggers vary from person to person.

03

Stress and tension

Emotional strain and stress affect bowel activity through the close connection between the gut and nervous system. This can intensify the symptoms.

What you can do yourself

  • Keep a food diary to identify your personal triggers and adjust your diet gradually.
  • Pay attention to regular meals and adequate fluid intake.
  • Incorporate relaxation techniques and regular physical activity into your daily routine to reduce stress.
  • Observe foods that cause bloating or are poorly tolerated and reduce them if necessary.
When a doctor's visit makes sense

If recurrent abdominal complaints persist over a longer period, an assessment by the family doctor is advisable, who will refer to gastroenterology if needed, in order to confirm the diagnosis and rule out other causes. Even if the complaints significantly burden everyday life, a medical consultation can help.
