Babies with nasal congestion, but no boogers can be seen in the nostrils, it is likely to be caused by deviated nasal septum, hypertrophic rhinitis and other reasons, or it may be caused by physiological factors. 1. Deviated septum: Due to the structural abnormality of the nasal cavity, the air flow rate and direction of flow are abnormal, which can lead to nasal congestion, but at this time, the secretion is relatively small, so you can’t see the boogers. 2. Hypertrophic rhinitis: it can cause hyperplasia of the inferior turbinate, leading to obstruction of nasal ventilation, children often feel nasal congestion, itchy nose, abnormal sense of smell, and boogers can not be seen when the secretion is small. 3. Physiological factors: dry air and other environmental factors can lead to nasal congestion in infants but no boogers can be seen in the nostrils. There may be other reasons for a baby’s stuffy nose but no boogers in the nostrils, such as allergic rhinitis, etc. It is recommended to consult a doctor in time to find out the cause of the problem and treat it accordingly.
