When children catch a cold, bacteria or viruses may invade the gastrointestinal tract, affecting its function and causing a loss of appetite. Therefore, when children show symptoms of a cold, in addition to fever, runny nose, and cough, they may also experience poor appetite, abdominal pain, bloating, and even vomiting and diarrhea. When a child has a loss of appetite due to a cold, in addition to treating the symptoms with cold medicine, we can also provide a light diet, encourage more water intake, and give easily digestible, vitamin-rich foods. Additionally, administering Chinese herbal medicine to strengthen the spleen and stomach can be beneficial.
