Irritable Bowel Syndrome (IBS)

Irritable bowel syndrome, or IBS, may affect as many as one in five people and is characterized by constipation, bloating, diarrhea, abdominal pain, and cramping. IBS is sometimes called by other names, including spastic colitis, mucous colitis, or spastic colon, but IBS does not normally cause permanent damage to the intestines or lead to serious diseases such as cancer, although it causes a great deal of discomfort.

Symptoms and Causes of Irritable Bowel Syndrome (IBS)

The most frequent symptoms of IBS are abdominal pain, bloating, and a feeling of discomfort, but can vary a great deal from one person to the next. Some people have constipation while others have diarrhea, with others going back and forth between the two. Any of these symptoms may disappear for a time, only to return, or they may never go away and even worsen over time.

Researchers have yet to find a single cause for IBS, but the immune system may be involved or the large intestine may be particularly sensitive to certain foods or stress. Bacteria in the small intestine has been the most recent area of study.

People who suffer from IBS may have a colon that temporarily stops working or that works intermittently. Food may move too slowly through the colon and cause constipation, or it can move too quickly and result in diarrhea.

Diagnosis of Irritable Bowel Syndrome

There is no single test for IBS, so diagnosis normally begins with a physical examination and a complete medical history and discussion of your symptoms. Blood tests, stool samples, and X-rays may be taken to rule out other conditions, and your gastroenterologist, Dr. Shamsi may need to perform a colonoscopy to study your colon.

If no other cause for your symptoms is found, IBS may be based on how frequently the discomfort has shown up during the past year, the appearance and disappearance of pain that accompanies bowel movements, and changes in the frequencies and nature of your bowel movements.

Treatment of Irritable Bowel Syndrome

There is no single drug or cure for IBS, so treatment may focus on reducing or eliminating particular symptoms of the condition. Medications to help with constipation, diarrhea, or abdominal pain may be prescribed, or a combination that includes antidepressants may be recommended.

A course of antibiotics may improve IBS for months to years <link to JAMA article>, and Dr. Shamshi has found great success treating his patients with IBS with this treatment plan.
