Frequent errors in the interpretation of breath tests in patients with suspected small intestinal bacterial overgrowth (SIBO)

Abstract

The letter highlights the growing issue of misinterpretation of the breath test in diagnosing SIBO, particularly in patients with slow intestinal transit. It warns of the risk of false negatives when key clinical factors are overlooked and gas curves are not properly interpreted. Additionally, it calls for a broader therapeutic approach beyond antibiotics, including alternatives such as phytotherapy, and emphasizes the need for improved clinical training in the interpretation of these tests.
