Inflammatory Bowel Disease | Symptoms, Causes & Treatment

What are IBD and IBS?

Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS) are two distinct gastrointestinal conditions that affect the digestive tract. Although they may share some symptoms, they differ significantly in causes, diagnosis, and treatment approaches.

IBD refers to chronic inflammatory conditions such as Crohn’s disease and ulcerative colitis, which cause visible damage to the gastrointestinal lining. It can result in severe complications if left untreated. IBS is a functional bowel disorder without any structural damage. It is characterized by abdominal discomfort and altered bowel habits such as constipation, diarrhea, or both. While not life-threatening, IBS can greatly impact quality of life. At Royal Care Hospital, our team of gastroenterologists provides advanced diagnostics, evidence-based treatments, and holistic support to help patients manage these chronic conditions effectively.
