Gut Health Breath Tests
At The Fern, we offer comprehensive specialty gut health testing to help uncover root causes to digestive symptoms and guide personalized care.
Our testing options include breath tests for small intestinal bacterial overgrowth (SIBO), lactose intolerance, fructose malabsorption, and sucrose malabsorption, among other specialized assessments.
By pairing thoughtful diagnostic evaluation with an individualized approach to gut health, we help patients and their providers better understand digestive concerns and develop targeted care plans.
Common Reasons to Book Breath Tests
- Bloating or gas after meals
- belly pain or cramping
- Diarrhea, constipation, or both
- Symptoms after dairy, fruit, or sweets
- Digestive symptoms that haven’t improved with other care
