Coughing and vomiting on crying may be caused by reflex stimulation of sensitive areas of the pharynx due to contracture of the muscles around the airway and esophagus during muscle tension.
The specific mechanism may be the following two aspects:
1. During crying, as the muscles of the whole body are in a state of tension and contraction, they are affected by the contracture of the muscles around the respiratory tract and esophagus, resulting in symptoms such as coughing and vomiting.
2. When crying, the nasal cavity within the entire respiratory tract secretions will increase significantly, reflexively stimulate the sensitive areas of the throat, resulting in coughing, vomiting and other uncomfortable symptoms, generally do not need to deal with, after stopping crying will generally improve.
If the coughing and vomiting are more serious, it is recommended to consult a doctor in time to avoid delays.
