Irritable bowel syndrome is a common functional bowel disorder that poses a significant healthcare burden, can seriously impair quality of life, and is the most commonly diagnosed gastrointestinal condition. It is estimated that the prevalence of irritable bowel syndrome is approximately 11.2% in the world and 12.8% in Turkey. Its etiology is not fully understood and many factors play a role. The most common symptoms include abdominal pain, straining, myalgia, feeling of urgency, and bloating. The disease is diagnosed according to Rome IV criteria. Its treatment is carried out by pharmacological and non-pharmacological methods. The goal of care in patients is to relieve symptoms, prevent complications, and restore patients' quality of life. The primary nursing role for patients with irritable bowel syndrome is to educate the patient with basic information about diagnosis and treatment regimens and to provide care by assessing the effects of patients' physical, social and psychological factors on their activities of daily living. Nurses should guide patients by informing them about important issues such as diet, complications of the disease, its causes, drugs used in treatment and possible side effects.
