You probably have heard of irritable bowel syndrome (or IBS). Many people confuse IBS with other conditions such as IBD (or inflammatory bowel disease), colitis, ulcerative colitis, Crohn's disease. Do you know what IBS is?

IBS is a collection of symptoms such as cramping, abdominal pain, bloating, diarrhea and constipation for 3 months or more. It is considered a “functional” condition in that it affects how the intestines work in the absence of major mechanical, inflammatory or biochemical diseases, determined by routine examinations. This means that there is no structural damage in the intestine.

If you have IBS, you are not alone. It is a common disorder that can affect approximately 1 in 10 people in the Western countries. It is also more common in younger persons (those under 50 years), women, or people with a family history of IBS.

Signs and Symptoms

IBS symptoms can be different depending on the person. Symptoms can come and go or may be worse on some days compared to others. In some people, symptoms may only occur after meals. Though IBS symptoms do not go away, generally they do not get worse over time.

Common symptoms of IBS include:

  • Abdominal pain and cramping
  • Diarrhoea and/or constipation
  • Bloating
  • Gassiness
  • Mucus in the stool
  • Feeling that you cannot fully empty your bowels
  • Some people with IBS may also experience nausea, heartburn, backache,
  • headache, urinary symptoms, and sleep problems


Though the exact cause for IBS is not known, doctors believe that the brain may be misfiring signals to the intestinal tract, causing abnormal muscle contractions or spasms. Some people with IBS may experience symptoms resulting from possible triggers. These include:

  • Eating—there is no food that causes IBS but certain foods may make symptoms worse (this will depend on the person); consult a healthcare provider to ensure you are meeting your dietary needs
  • Hormonal changes, such as monthly periods
  • Other digestive tract diseases, such as infection
  • Medicines, such as antibiotics

See Your Doctor

If you are having symptoms, make an appointment with your GP or a specialist (such as a gastroenterologist). While there is no cure for the disorder, there are treatments that can help improve IBS symptoms. You and your doctor can discuss the best approach to help relieve your symptoms with the use of medicines. Your doctor can also help you to identify factors that trigger your symptoms and to make changes in your diet and lifestyle to avoid these triggers.

Remember to keep notes about your symptoms because IBS is usually diagnosed and treated based on them. Your doctor may run tests to make sure it is not another GI condition. In addition to a physical exam, he or she may ask you questions about your symptoms and medical history. Be prepared to discuss the following with your doctor:

  • What are your symptoms? Do you experience mostly diarrhoea or constipation? Or both?
  • How often do you experience symptoms of IBS?
  • When did your symptoms start?
  • Are your symptoms worse after eating, during your periods (for women), after taking medications or during stressful situations?
  • What are your eating habits?
  • What other medical conditions do you have?
  • What medications do you take?
  • Do you have a family history of IBS or other gastrointestinal disorders?

IBS is a chronic condition that requires long-term treatment. Though symptoms can vary, people experiencing mild ones often do not seek medical treatment. Regardless of the severity of symptoms, it’s important to remember that no one has to suffer from IBS alone.
