Irritable Bowel Syndrome – IBS | Bangkok Hospital Phitsanulok

What Is Irritable Bowel Syndrome (IBS)?

Irritable Bowel Syndrome (IBS) is a chronic disorder of the digestive system that is not caused by inflammation, infection, or intestinal parasites. Instead, it results from abnormal functioning of the intestinal muscles, which can lead to discomfort, abdominal cramping, diarrhea, constipation, or alternating episodes of both.

Although IBS is not life-threatening, if left unmanaged, it can significantly impact one’s quality of life.

Common Symptoms of IBS

Recurring abdominal pain or cramping, often relieved after a bowel movement
Diarrhea, constipation, or alternating between the two
Bloating, gas, and abdominal distension
A sensation of incomplete evacuation or frequent urge to defecate
Symptoms may worsen with stress or insufficient rest

Important: IBS typically does not present with blood in the stool or fever. If these symptoms occur, seek medical attention immediately.

Causes and Risk Factors

The exact cause of IBS remains unclear, but several contributing factors have been identified:

Abnormal intestinal motility—either too fast or too slow
Hypersensitivity of the gastrointestinal nervous system
Emotional factors such as stress, anxiety, or depression
Certain dietary triggers, including fatty foods, dairy, and alcohol
History of intestinal infections or food poisoning
