What is the first treatment for irritable bowel syndrome?

IBS can involve abdominal pain, bloating, diarrhoea, constipation, or alternating bowel habits. A clinician first considers your symptom pattern and checks whether another problem needs attention. Treatment is then matched to the main symptoms rather than using one plan for everyone. Food changes may include regular meals, adjusting fibre gradually, and noticing whether particular foods worsen symptoms. Restricting many foods without guidance can make eating less balanced.

Arrange a GP Consultation if symptoms are new, persistent, or interfering with daily life. Keep a brief record of meals, bowel movements, pain, bloating, and stress or sleep changes. Bring this to the appointment. A clinician may suggest Nutrition Counselling for a structured eating plan or Food Intolerance Testing when the history supports it. Introduce one change at a time and allow enough time to see its effect. Do not stop prescribed medicines or remove major food groups without professional advice.

Seek prompt medical advice for blood in the stool, black stool, unexplained weight loss, fever, repeated vomiting, severe or worsening abdominal pain, or symptoms that wake you regularly. Get urgent help if pain is intense, your abdomen becomes swollen and hard, or you cannot keep fluids down. These features need assessment rather than being assumed to be IBS.

Which symptom should we target first? Could my medicines or eating pattern be contributing? Would a dietitian-led plan be suitable? Do I need testing before changing my diet?
