After catching a cold, various respiratory symptoms can occur, such as nasal congestion, runny nose, cough, sore throat, etc. However, there is also a category of patients who, particularly after a viral cold, may exhibit symptoms such as headache, nausea, vomiting, and even abdominal pain and diarrhea. These patients are referred to as having a "gastrointestinal cold." Like the common cold, a gastrointestinal cold is also caused by respiratory virus infections. Therefore, there are no special medications required for treatment; general over-the-counter cold medicines are sufficient. If there is severe vomiting, some antiemetic medication may be used, and drinking some cola boiled with ginger can also be very effective in treating the headaches and vomiting.
