Irritable Bowel Syndrome (IBS)<\/strong> is a common functional gastrointestinal disorder<\/strong> that affects the large intestine. It is characterized by recurring abdominal pain, bloating, and changes in bowel habits such as diarrhea or constipation. Although IBS is a chronic condition, it does not cause permanent damage to the intestines and can be effectively managed with lifestyle changes and medical care.<\/p>\n\n\n\n

What Is Irritable Bowel Syndrome?<\/h2>\n\n\n\n

IBS is a disorder of the gut\u2013brain interaction<\/strong>, meaning the digestive tract appears normal but does not function properly. People with IBS often have a sensitive digestive system that reacts strongly to certain foods, stress, or hormonal changes.<\/p>\n\n\n\n
