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.

CLINICAL TAKEAWAYS FROM THIS EPISODE
- Using the Voice as a Functional Assessment Tool in Whole-Person Care
- Changes in vocal tone, strength, endurance, or ease can provide early clues to systemic stressors such as inflammation, neuroendocrine imbalance, sleep disruption, microbiome dysfunction, or neurological or autonomic issues (Stachler et al., 2018).
- Integrative Treatment Considerations for Voice-Related Symptoms
- When vocal changes are present, supportive strategies may include addressing reflux, nutrient insufficiencies, nervous system regulation, breath mechanics, posture, microbiome optimization, referral to physical therapy and more (Stachler et al., 2018).
GUEST INTRODUCTION
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.
LABS, NUTRITION, AND LIFESTYLE SUPPORT
Dr. Dahl’s Clinical Lab Considerations for Voice Issues and Cough
- Inflammatory and metabolic markers as clinically appropriate (Stachler, 2018).
- Hormonal assessment as clinically indicated (Yalim, 2025).
Dr. Dahl’s Nutrition and GI Support Considerations for Vocal Issues and Chronic Cough
- Hydration assessment and counseling (Verdolini, 1994).
- Address reflux holistically if present (Stachler, 2018).
- Support the microbiome as clinically indicated and consider candidiasis overgrowth in patients with a history of oral corticosteroid use (Pinto, 2013).
Lifestyle and Nervous System Support for Voice
- Consider humidified air and environmental support for laryngeal tissue health (Levendoski, 2014).
- Vocal hygiene education, including pacing and rest—even in non-performers.
- Referral to voice therapy when functional misuse or strain is suspected (Wolfberg, 2024).
