  • Clinically Speaking with a Pediatric Pulmonologist: Dr. Wadha Alotaibi

    Clinically Speaking is PodBites’ special interview series where we step beyond textbooks and into real clinical practice — sitting down with specialists to explore how medicine is actually practiced, how clinical decisions are made, and what it truly means to care for patients.

    In this episode,Our host Abdulah Alotaibi sits down with Dr. Wadha Alotaibi, Pediatric Pulmonologist at King Fahad Medical City Hospital (KFMC), to explore the clinical world of pediatric respiratory medicine through the lens of a specialist working on the frontlines.

    From evaluating a child with a persistent cough to managing complex chronic respiratory conditions, Dr. Alotaibi shares her clinical approach, diagnostic reasoning, and real-world insights into pediatric lung disease — offering valuable perspectives for students transitioning from theory to practice.
