Do I Have IBS? (Quiz)

Medically Reviewed by: Nicole Anne Vergara, RD

Did you know that about 2,000 patients with Irritable Bowel Syndrome (IBS) have been diagnosed with the condition approximately after 6 years of experiencing various symptoms?

Overall, Irritable Bowel Syndrome affects 5 to 15% of the entire population in the world.

IBS symptoms can resemble those of other GI disorders, making a diagnosis challenging. You can use the questionnaire below to assess whether you need to see a doctor to further investigate your GI problems.

No matter how this self-test turned out; if your symptoms are affecting your quality of life, see a doctor. To effectively treat your pain, it's critical to identify the underlying cause of it.

If you are worried about the digestive issues that you are currently experiencing, but you don't know if you have Irritable Bowel Syndrome, this quiz can give you an overview of whether you can have IBS.

IBS Symptoms

Before we start the quiz, we will be talking about the common IBS symptoms that you should be taking note of.

These symptoms may or may not happen to an individual so taking note of all your symptoms can help your physician diagnose your condition more accurately.

Persistent Abdominal Pain

One of the main symptoms of IBS diagnosis is persistent abdominal pain. It was reported that IBS patients experience abdominal pain and discomfort for 3 months or longer.

Taking note of the length and frequency of abdominal pain is important for an accurate diagnosis of Irritable Bowel Syndrome.

Irregular Bowel Movements

Having irregular bowel movements can be your predominant symptom of IBS. These inconsistencies may include frequent diarrhea or constipation.

You may be diagnosed with IBS-D for diarrhea as your predominant symptom, IBS-C for constipation, or IBS-M if you have mixed symptoms.

Bloating, Distention, and Excessive Gas

Chronic inflammation in your gastrointestinal system results in bloating, distention, and excessive gas.

Inflammation happens when an individual consumes a certain type of "trigger" food that causes inflammation to the GI's inner lining.

These symptoms may be relieved by over-the-counter medications and home remedies. However, IBS symptoms vary from one person to another. Getting professional medical advice is the best thing to do to make sure you get the treatment that fits your condition.

Testing for IBS

Diagnosing Irritable Bowel Syndrome (IBS) requires various tests to rule out other conditions. This medical condition mimics other diseases and gut conditions.

Thus, your healthcare provider would recommend you take one or more of these tests:

Breath Test

Breath tests are done to check for any bacterial overgrowth to diagnose IBS.

The overgrowth of bacteria usually happens for people who have undergone bowel surgeries or other diseases that can cause digestion to slow down.

Blood Test

Complete blood screening is usually done to check for the presence of anemia or other abnormalities related to IBS.

This screening can also check for gastrointestinal tract inflammation, tissue damage, or celiac disease.


A colonoscopy utilizes a small and flexible tube with a camera that allows physicians to examine any discrepancies in the colon and GI tract.

Stool Tests

Stools are examined to check for the presence of any parasites and bacteria in your digestive tract.

Lactose Intolerance Test

Individuals with lactose intolerance do not produce enough lactase. Lactase is an enzyme used to digest the sugar from dairy products.

This intolerance can lead to abdominal pain, excessive gas, and diarrhea which are the same symptoms of Irritable Bowel Syndrome (IBS).

Anorectal Manometry

Anorectal manometry is a test used to evaluate the function of the anal sphincter muscles and the rectum. It is often used to help diagnose conditions such as irritable bowel syndrome (IBS).
