The first step in the healing process is to consult a health professional to confirm your suspicion of IBS and rule out any other possible medical conditions that may be creating or contributing to your symptoms. Once an IBS diagnosis has been confirmed by a health professional, LofoFoodie recommends seeking out a qualified Low Fodmap dietitian for a consultation.

There are no specific lab tests that can diagnose IBS. Your doctor will see if your symptoms match with the definition of IBS, and may run tests to rule out conditions such as:
- Food allergies or intolerances, such as lactose intolerance and poor dietary habits
- Medications such as high blood pressure drugs, iron, and certain antacids
- Enzyme deficiencies where the pancreas isn’t releasing enough enzymes to properly digest or break down food
- Inflammatory bowel diseases like ulcerative colitis or Crohn’s disease
Tests that may be carried out to eliminate other possible issues may be :
- Flexible sigmoidoscopy or colonoscopy to look for signs of blockage or inflammation in your intestines
- Upper endoscopy if you have heartburn or indigestion
- Blood tests to look for anemia (too few red blood cells), thyroid problems, and signs of infection
- Stool tests for blood or infections
- Tests for lactose intolerance, gluten allergy, or celiac disease
