Children often have cough symptoms after a cold, and there are many babies who may vomit as soon as they cough. This condition is due to respiratory infections on the one hand, and then it may be due to sputum or irritation of the pharynx when coughing. Babies have a lack of resistance and have a high chance of catching a cold, and coughing symptoms often occur after illness. If the cough is more intense, it may lead to shortness of breath or uneven gasping and cause vomiting in babies. When a baby has a severe cough, he or she needs to go to the hospital in time to receive targeted treatment and cough suppressant therapy under the guidance of a doctor, and the cough will be controlled and the vomiting will improve. At the same time, infants who vomit when they cough may have accumulated a lot of phlegm in their throats, and coughing stimulates the phlegm to the esophagus, which can lead to vomiting. In addition, pathogenic infections such as bacteria or viruses that cause colds can also affect the baby’s digestive system, leading to gastrointestinal disorders and indigestion, which can also lead to coughing and vomiting. You should pay attention to give your baby some easily digestible food, you can take some probiotics or digestive drugs.
