What is irritable bowel syndrome?

Irritable Bowel Syndrome Q & A

What is irritable bowel syndrome?

Irritable bowel syndrome or IBS is a condition that causes symptoms in the large intestine without causing the inflammatory changes in bowel tissue seen in inflammatory bowel disease (IBD). Although it doesn't have the same risks as IBD, IBS is a chronic condition that requires long-term management to relieve symptoms.

What are the symptoms of IBS?

The symptoms of IBS can vary over time and from patient to patient, but generally, they include:

  • diarrhea

  • constipation

  • belly cramps

  • bloating

  • gas

  • nausea

  • mucus in the stool

What causes IBS?

The exact cause of IBS is not known, but symptoms can be triggered by certain foods, stress, hormonal changes or illnesses, as well as an imbalance of healthy bacteria in your gut. Abnormalities in the nerve pathways that control your bowels may also play a role.

How is IBS diagnosed?

In most cases, a physical exam and medical history can enable Dr. Sherman to diagnose IBS. Sometimes though, additional testing may be needed to rule out other possible causes of symptoms, especially if symptoms first appear after age 50 or if you have:

  • unintended weight loss

  • fever

  • bleeding from your rectum

  • recurrent vomiting

  • persistent diarrhea that may wake you from sleep

  • anemia

  • significant belly pain that doesn't go away after a bowel movement

How is IBS treated?

Many patients can manage IBS symptoms with lifestyle changes, especially changes in diet that can help them avoid foods that trigger symptoms. Learning to manage stress, another common trigger, can also help. Medical treatment is primarily focused on using medications to help treat specific symptoms, such as diarrhea or excessive gas and bloating. Dr. Sherman will develop a treatment plan based on your specific symptoms for the best results.
