Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder (gut condition) which affects approximately 15% of the population. It is a functional disorder, as it cannot be identified by finding abnormalities in the gastrointestinal (GI) tract, but its diagnosis comes from the symptoms that people experience and which are not associated with other illnesses.
Irritable Bowel Syndrome (IBS) is also known as nervous colitis, nervous colon and spastic bowels.
IBS affects around 10 – 15 % of the adult population, but only about 5% have been diagnosed.
IBS sufferers can experience various symptoms from the esophagus and stomach area to the bowels, such as:
- Abdominal pain
- Bloating (pressure in the abdomen)
- Distension (the abdomen increases in circumference)
- Noisy abdomen
- Diarrhea (IBS-D)
- Constipation (IBS-C)
- Alternate diarrhea and constipation (IBS-A)
- Passing of mucus when defecating
- Acid reflux and heartburn
The severity of IBS symptoms varies from person to person, with some people experiencing symptoms that come and go, while others have to deal with much severe daily bowel problems which affect their work, sleep and their ability to enjoy life.
What causes IBS?
At present we are not 100% sure about the exact cause of Irritable Bowel Syndrome (IBS), but it seems that a faulty communication between the brain and the intestinal tract could be causing abnormalities in how the GI tract deals with its content.
Other elements to take in consideration may be:
- Food – although no specific food has been proved to cause IBS, certain food can cause the symptoms
Abnormality in the gut bacteria
- Medicines – like antibiotics
- Infection in the digestive system
- Stress and other psychological problems – like depression or anxiety
- Changes in the hormones – more prevalent in women during their monthly period
- Genetic reason
- Joint hyper mobility (it seems that people who have this condition have a higher probability of suffering from IBS as the muscles that squeeze food through the digestive system are weaker)
While there is no definite way to test IBS, a physician can diagnose IBS if a person shows the typical signs and symptoms that are related to the syndrome. The doctor will also ask about a person’s medical history, after examining and testing the abdomen to determine if internal organs are larger than normal. Doctors will also look into the most common symptoms of abdominal pain, bloating, changes in bowel habits, etc. The most common way to diagnose IBS is the Rome criteria.
A lot of the IBS symptoms are common to other illnesses and therefore your doctor may also carry out some tests to eliminate any other ailments, which can cause similar symptoms:
- Blood tests
- Stool sample, to check for blood or evidence of infection
- Sigmoidoscopy, in which a flexible, lighted tube with a tiny camera at the end is inserted into the rectum and up the left side of the colon
- Colonoscopy, in which a longer tube is used to examine the entire colon
Research has indicated that altering one’s diet can improve symptoms of IBS. While it does take long to discover what works well for an individual suffering with IBS, keeping track of one’s diet and staying away from the foods which seem to trigger symptoms of IBS is a good way to go. The low FODMAP diet has been proven successful in relieving those nasty IBS symptoms for the majority of IBS sufferers. The following are just some of the foods that have proven to flare up symptoms of IBS:
- Onion, garlic, cauliflower, corn, peas, sweet potato, most beans
- Most fruit juices
- Some dairies such as milk, custard, yoghurt
- Honey, some jams types
- Certain fruits like apples, apricots, avocado, cherries, grapefruit, mango, nectarine
- Carbonated drinks, gums and beverages which contain artificial sweetener.
When to Call a Professional
To be safe, contact your doctor if you notice the following:
- Unexplained weight loss/weight gain
- Blood in your stool
- Abdominal pain that is accompanied by vomiting, dizziness or fainting
- Abdominal pain or diarrhea during night time.
While there is no cure for IBS, most people can lessen the distressing symptoms by following a low-FODMAP diet .
Needless to say, it is always a good idea for those who have already been diagnoses with IBS to get the help of a dietitian specialised on the low FODMAP diet.
If you want to learn more about IBS, here is a very informative lecture from Prof. Peter Gibson, Professor and Director of Gastroenterology at The Alfred and Monash University. (Don’t be scared by the length of the video, this lecture is packed with must know information for those suffering from IBS!)
