When a baby has a cough accompanied by nausea, dry heaving and vomiting, it is often caused by laryngitis. When inflammation occurs in the throat, there is congestion and edema, and the swelling of the pharynx causes some irritation, so that nausea as well as dry heaving and vomiting can occur. Because the pharynx belongs to the nasopharynx, which is the common channel of the respiratory system and the digestive system, at this time, in addition to the symptoms of the digestive system, there will also be symptoms of the respiratory system, which will cause the symptoms of coughing. If it is accompanied by bacterial infection, you also need to give your baby antibiotics for treatment at the same time, such as pediatric cefixime granules or pediatric cefadroxil, the anti-inflammatory effect is relatively good.
