The child coughing throat hissing sound may be caused by bronchitis, laryngitis, congenital laryngeal asthma and other diseases.
1. Bronchitis: mainly caused by pathogen infection, such as bacteria, viruses and so on. At the onset, the child will experience an increase in phlegm, which leads to a hissing sound when coughing.
2. Laryngitis: laryngitis is an inflammatory reaction in the larynx, which may be caused by pathogenic infections. Prolonged overuse of the voice, acid reflux or lower respiratory tract infections can also lead to laryngitis, and the child will have a barking cough, which will make the throat hiss when coughing.
3. congenital laryngeal wheezing: congenital laryngeal wheezing is caused by excessive relaxation of the soft tissues of the larynx, which may be caused by immaturity of the airway and digestive tract nerves, and the child will have a chicken-like wheezing sound, which makes the throat hiss when coughing.
There are more reasons why a child’s coughing voice makes a hissing sound, and it needs to be examined promptly and treated according to the specific cause.
