What is the prevalence of Irritable Bowel Syndrome?

Irritable Bowel Syndrome (IBS) is a common gastrointestinal disorder that affects a significant portion of the population worldwide. The prevalence of IBS varies across different regions and populations. According to various studies, it is estimated that IBS affects around 10% to 15% of the global population. However, the exact prevalence is challenging to determine due to underreporting and misdiagnosis.

IBS is more commonly diagnosed in women than men, with a female-to-male ratio of approximately 2:1. It can occur at any age, but it often starts in early adulthood. The symptoms of IBS can vary in severity and may include abdominal pain, bloating, diarrhea, constipation, or a combination of both.

While the exact cause of IBS is unknown, several factors are believed to contribute to its development, including abnormal gastrointestinal motility, visceral hypersensitivity, gut-brain axis dysfunction, and psychological factors such as stress and anxiety.

It is important to note that IBS is a chronic condition that requires long-term management. Although it can significantly impact an individual's quality of life, various treatment options, including dietary changes, stress management techniques, and medications, can help alleviate symptoms and improve overall well-being.
