Rhinitis has the potential to affect the growth and development of the patient, so it can affect the growth. Children with rhinitis must actively control the symptoms. If the child often sleeps at night with nasal congestion, open-mouth breathing or even wakes up suffocating, it means that the child has a serious obstructive problem and will lack oxygen during sleep, and will be drowsy and weak during the day, which affects the growth and development of the child. Active application of medication is recommended, commonly used is budesonide nasal spray or mometasone furoate nasal spray. If it is allergic, you also need to add oral anti-allergy drugs, commonly used is cetirizine hydrochloride syrup. Symptomatic treatment will improve the child’s symptoms of nasal congestion and can avoid affecting the child’s growth and development.
