A cold is an inflammatory condition of the upper respiratory tract. When a patient's immune function is decreased and they are inadvertently exposed to cold, this can lead to the invasion of viruses, bacteria, and pathogens into the respiratory tract, causing clinical symptoms such as nasal congestion, runny nose, and sneezing. Colds can be divided into heat-type colds and cold-type colds based on the timing of onset and the different clinical symptoms that appear. Heat-type colds generally occur more often in summer. If a patient also experiences vomiting, the first step is to determine whether the cold is caused by a viral infection. If it is, appropriate antiviral medications and medications to clear heat and detoxify can be utilized to treat the symptoms. Once the symptoms of the cold are effectively controlled, the symptoms of vomiting will also subside. Of course, care must be taken to ensure a bland diet for patients with heat-type colds who experience vomiting, avoiding spicy and irritating foods until the condition is effectively controlled, after which the diet can gradually return to normal.
