Expert Irritable Bowel Syndrome Care at Weill Cornell Medicine

Irritable Bowel Syndrome (IBS) is a common disorder in which the large intestine does not function properly. People with IBS can experience a range of symptoms including abdominal pain, constipation diarrhea or both.

IBS is a chronic, long-term condition that does not have a cure. The exact cause of IBS is not known.

Thankfully, with expert IBS care, you can improve your quality of life. Our board-certified gastroenterologists help patients diagnose IBS, identify triggers, and treat symptoms.

Irritable Bowel Syndrome Prevention and Screening

IBS risk factors: Many people experience IBS symptoms from time to time, but do not have the syndrome. You are more likely to develop IBS if you: 

Are under the age of 50
Are female
Have a family history of IBS
Have a mental health illness, such as anxiety or depression

Prevention strategies: Reducing stress and improving diet are effective ways to prevent and lessen IBS symptoms. Our leading gastroenterologists recommend that patients:

Work with a registered dietician to help identify any food triggers
Receive psychotherapy to help manage stress more successfully
Learn and practice stress-reducing techniques

Irritable Bowel Syndrome Symptoms

IBS signs and symptoms vary from person to person. They also may lessen or worsen over time. The most common symptoms include:

Abdominal pain
Cramping
Bloating
Excess gas
Constipation
Diarrhea
Mucus in stool
● Other persistent change in bowel movement patterns

How We Diagnose Irritable Bowel Syndrome

Diagnostic tests and imaging: [P] There is no definitive test for IBS. In fact, there is no sign of the disorder when the intestine is examined. A set of criteria can be used to diagnose IBS based upon the physician taking a careful history and performing a physical examination. Depending upon a person’s individual symptoms, some testing may need to be done to evaluate for other conditions. These tests may include:

Blood, urine, and stool tests
Colonoscopy
Abdominal imaging tests, such as x-ray or ultrasound
Food intolerance tests, such as lactose or gluten intolerance tests
Anorectal manometry

If the testing is performed and confirm that the symptoms are not caused by another disease or disorder, your physician will then carefully discuss your symptoms and if you meet the criteria, you will be diagnosed with IBS.

Successful IBS treatment incorporates many different strategies — such as diet, exercise, stress reduction, and medication. At Weill Cornell Medicine, all patients receive a personalized treatment plan that addresses their unique triggers, symptoms, and lifestyle goals.

Diet: Many IBS patients greatly benefit from tracking their food intake and symptoms. This helps identify specific food that triggers symptoms. In addition to eliminating these foods, IBS patients may also be recommended to:

Eat more high-fiber foods
Eat smaller, more frequent meals
Drink six to eight glasses of water per day
Avoid foods that are known to commonly trigger IBS symptoms, including caffeine, fatty foods, dairy, alcohol, and chocolate
