Irritable bowel syndrome (IBS) is a common gastrointestinal disorder that affects millions of people around the world. It is characterized by abdominal pain, bloating, and changes in bowel movements. Symptoms may be mild or severe and can be triggered by a variety of factors, including stress, diet, and certain medications. IBS is believed to be caused by a combination of physical and psychological factors. There is no single test that can diagnose IBS, so it is typically diagnosed through a combination of physical examination, medical history, and laboratory tests. The most common treatment for IBS is lifestyle changes, such as eating a balanced diet and avoiding foods that trigger symptoms. Stress management can also be beneficial. Medications, such as antispasmodics, antidepressants, and laxatives, may be prescribed to help relieve symptoms. Some people may benefit from therapies such as cognitive behavioral therapy (CBT) or hypnotherapy. IBS can be disruptive and can have a negative impact on quality of life, but there are ways to manage symptoms and improve overall health. Working with a healthcare provider to identify triggers, develop a plan to manage symptoms, and make lifestyle changes can be beneficial.
