[|Human|] My 7 month old baby sounds really chesty when he is playing. He has no temperature, hes eating and theres plenty of wet nappies. Theres no noise when he sleeps and he is well in himself. His GP says his chest is clear so could it be allergies, or to do with teething? Thanks in advance.
[|AI|]  Hi...what you are describing is fitting into a condition called congenital airway anomaly. In this the breathing tubes will be slightly lax, and they will get better as the age progresses. This is a quite common thing which is increasingly being recognized nowadays. You need not worry if his growth parameters and development are normal. As far as diagnosis is concerned it is mostly clinical and the gold standard diagnostic test is bronchoscopy. Many a time this might be mistaken as wheezing, but careful examination shows that the noise is mostly inspiratory and not expiratory. Wheeze is usually expiratory. Regards -
