What is Irritable bowel syndrome?
Irritable bowel syndrome is a disorder characterized most commonly by cramping, abdominal pain, bloating, constipation, and diarrhea. IBS causes a great deal of discomfort and distress, but it does not permanently harm the intestines and does not lead to a serious disease, such as cancer. Most people can control their symptoms with diet, stress management, and prescribed medications. For some people, however, IBS can be disabling. They may be unable to work, attend social events, or even travel short distances.
As many as 20 percent of the adult population, or one in five Americans, have symptoms of IBS, making it one of the most common disorders diagnosed by doctors. It occurs more often in women than in men, and it begins before the age of 35 in about 50 percent of people.
What are the symptoms of Irritable bowel syndrome?
Symptoms range from mild to severe, however most people have mild symptoms. IBS symptoms may be worse in patients with underlying stress or mood disorders such as anxiety and depression, but it is important to understand that these conditions do not cause IBS. Symptoms may include:
