Claim: Babies born with tracheomalacia, which can also affect the voice box, may have other health issues like a heart defect, reflux or developmental delay with mild to severe symptoms like noisy breathing.
Evidence: The same condition can also affect the larynx, which is called laryngomalacia. The larynx (/ˈlærɪŋks/), commonly called the voice box, is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration. Babies born with tracheomalacia may have other health issues like a heart defect, reflux or developmental delay. Symptoms can be mild to severe. Symptoms inside the lung include noisy breathing that may get better when you change your baby's position or while he or she is asleep.
