Diagnosing IBS can be really tricky: symptoms can vary widely from person to person, and even from day to day. They can come and go, and may be aggravated by stress and anxiety.
Despite this, IBS is one of the most common gut disorders, affecting around 5-10% worldwide (although many more cases are thought to go undiagnosed).
The exact cause isn’t fully understood, but involves interaction between the gut and the brain. This can increase sensitivity to normal gut movements and affect how things move through the gut.
The most common symptoms include abdominal pain, bloating, gas, and changes in bowel movements (diarrhoea, constipation, or both). Some people with IBS also report headaches, muscle pain, chronic fatigue, depression, and sleep difficulties.
There’s currently no test to diagnose IBS, which is what makes diagnosis so challenging. Tests can be done to rule out other conditions, by diagnosis is usually based on symptom history. Elimination and re-introduction diets (such as the low-FODMAP diet) can help identify trigger foods.
❗️ If you’re experiencing ongoing symptoms that impact your quality of life, your first step is to see with your doctor for testing and to rule out other conditions BEFORE eliminating any foods from your diet. This is really important, as some tests (eg. for coeliac disease) require you to have the allergen in your diet to give accurate results.
