What is Irritable Bowel Syndrome (IBS)? Symptoms, Causes & Treatment
Irritable Bowel Syndrome (IBS)
Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder, meaning it affects how your digestive system works rather than causing structural damage. It mainly impacts the large intestine and can lead to recurring digestive discomfort.
