How is Irritable Bowel Syndrome diagnosed?



Irritable Bowel Syndrome (IBS) is a common gastrointestinal disorder that affects the large intestine. It is characterized by a variety of symptoms, including abdominal pain, bloating, gas, diarrhea, and constipation. Since these symptoms can also be indicative of other conditions, diagnosing IBS can be challenging. However, healthcare professionals follow a systematic approach to reach a diagnosis.



Medical History: The first step in diagnosing IBS is a thorough medical history evaluation. The doctor will ask about the patient's symptoms, their duration, and any triggers or patterns associated with the symptoms. They will also inquire about the patient's medical history, family history, and any previous gastrointestinal issues.



Physical Examination: A physical examination is conducted to rule out other potential causes of the symptoms. The doctor will palpate the abdomen to check for any abnormalities or tenderness. They may also listen to bowel sounds using a stethoscope.



Rome Criteria: The Rome criteria are widely used to diagnose IBS. These criteria help standardize the diagnosis by defining specific symptoms and their duration. According to the Rome IV criteria, a patient must experience recurrent abdominal pain or discomfort for at least one day per week in the last three months, along with two or more of the following: improvement with defecation, change in stool frequency, or change in stool form.



Diagnostic Tests: While there is no specific test to definitively diagnose IBS, certain tests may be performed to rule out other conditions. These tests may include:




  • Blood tests: Blood tests can help identify any signs of inflammation or infection in the body. They can also check for celiac disease or other conditions that may mimic IBS symptoms.


  • Stool tests: Stool samples may be analyzed to check for the presence of blood, infections, or parasites. This helps rule out conditions such as inflammatory bowel disease or infections that can cause similar symptoms.


  • Colonoscopy: In some cases, a colonoscopy may be recommended to examine the lining of the colon and rule out conditions like inflammatory bowel disease or colon cancer. During this procedure, a flexible tube with a camera is inserted into the rectum to visualize the colon.


  • Flexible sigmoidoscopy: Similar to a colonoscopy, a flexible sigmoidoscopy allows the doctor to examine the lower part of the colon using a flexible tube with a camera. This procedure is less invasive than a colonoscopy and may be used if symptoms are primarily in the lower part of the colon.


  • Imaging tests: In some cases, imaging tests such as an abdominal X-ray, CT scan, or MRI may be ordered to rule out other conditions or detect any structural abnormalities in the digestive tract.



Elimination Diet: In certain situations, an elimination diet may be recommended to identify specific food triggers that worsen IBS symptoms. This involves removing certain foods from the diet and gradually reintroducing them to observe any changes in symptoms.



Additional Considerations: It is important to note that IBS is a diagnosis of exclusion, meaning other conditions must be ruled out before confirming IBS. The symptoms of IBS can vary greatly among individuals, and there is no definitive test to diagnose it. Therefore, healthcare professionals rely on a combination of medical history, physical examination, and diagnostic tests to reach a diagnosis.



If you suspect you may have IBS, it is crucial to consult with a healthcare professional who can evaluate your symptoms, perform the necessary tests, and provide appropriate guidance and treatment options.

There is no way of getting a definitive test. Most General Practitioners will investigate and do a thorough medical history examination which is vital to rule out any other causes first. IBS often runs in families who have food sensitivities or several types of allergies so this would certainly help with diagnosis. Blood tests may be run to check for other conditions. A nutritionist / dietician will help to work out a eating plan and help to eliminate certain types of foods that likely trigger the IBS. Keeping a record of what you eat, when and what if any reactions to specific foods are encountered. The more information you are able to provide to your medical team the better it will help to establish IBS.
