Why PPIs Often Fail for Voice Problems

Nearly one in three adults will experience a voice disorder at some point in their lifetime, often without realizing it may be connected to their overall health (Stachler et al., 2018). In this episode, we sit down with integrative otolaryngologist Dr. Linda Dahl to unpack how subtle changes in vocal tone, stamina, and clarity can serve as early clues to what’s happening systemically - from inflammation and hormonal shifts to nervous system stress, reflux, and microbiome changes - and what to do next depending on what you hear. From simple in-office listening strategies and targeted questions to appropriate referrals, lab considerations, and integrative support options, this episode helps clinicians effectively resolve common voice issues using a whole person approach. 

Dr. Linda Dahl, MD, is a board-certified otolaryngologist, voice specialist, and integrative ENT physician. Her clinical work focuses on functional voice disorders, laryngeal health, and the intersection of vocal performance with systemic physiology. Dr. Dahl is known for integrating conventional ENT diagnostics with evidence-informed strategies that address inflammation, reflux, hormonal balance, and nervous system regulation. She regularly educates clinicians on using the voice as a meaningful window into whole-person health.
