Pediatric Hydrogen Breath Testing
A simple, non-invasive way to evaluate lactose intolerance, fructose malabsorption, and SIBO in kids and teens.
Hydrogen breath testing is a non-invasive test that helps identify carbohydrate malabsorption (lactose, fructose) and small intestinal bacterial overgrowth (SIBO) in children with chronic GI symptoms.
Dr. Mendez orders breath testing only when it will help direct treatment, and pairs results with a practical diet and management plan, not just a printout.
Conditions & concerns we address
Lactose Intolerance
Confirming lactose malabsorption in kids with bloating, gas, or diarrhea after dairy.
Fructose Malabsorption
Evaluating reactions to fruit juices, sweetened drinks, and high-fructose foods.
SIBO Evaluation
Considered in select kids with bloating, distension, and altered bowel habits, often after antibiotics or in motility disorders.
Chronic Bloating
Helping sort gas and bloating into specific, addressable patterns.
Persistent Diarrhea
Used alongside other testing when carbohydrate intolerance is on the differential.
How Dr. Mendez approaches care
- Careful selection so testing is offered when results will meaningfully change the plan.
- Clear pre-test prep instructions for diet, antibiotics, and probiotics.
- Coordinated scheduling at partnered pediatric facilities.
- Results reviewed with you in plain language, with a written plan.
- Dietitian collaboration when ongoing diet adjustments are needed.
Signs it's time for a consultation
- Bloating, gas, or diarrhea consistently linked to dairy or specific foods.
- Chronic bloating without a clear explanation.
- Suspected SIBO, especially after repeated antibiotics or in motility issues.
- A prior breath test result you want re-interpreted in context.
