Irritable bowel syndrome – a common problem, individual approach
Irritable bowel syndrome is a recurrent abdominal pain that occurs at least once a week for 3 months, with symptoms at least 6 months associated with at least two features: bowel movements, change in bowel frequency, change in the appearance of stools. According to the Rome IV Diagnostic Criteria, the disease is diagnosed on the basis of clinical symptoms. This does not apply to people over 50 years of age (and in the case of first-degree relatives of patients with colorectal cancer after 45 years of age) and patients with alarm symptoms. Due to the lack of a single etiological factor, the treatment of irritable bowel syndrome consists in reducing symptoms and improving the patient’s quality of life. Non-pharmacological treatment includes a high-fiber diet and modification of the microbiota. The most effective drugs are antispasmodics directly affecting the smooth muscle, inhibiting the influx of calcium, i.e. drotaverine, mebeverine and alverine. There has been proven effectiveness of antidepressants. This confirms that functional disorders of the gastrointestinal tract are a manifestation of the dysfunction of the brain–gut–microbiota axis.
