When there is a cough, most of them are caused by respiratory tract infections, which are easily accompanied by fever, cough and phlegm, as well as symptoms of poor appetite and digestion. If you eat more sweets at this time, it will affect the digestion of the stomach, which will cause excessive secretion of stomach acid, aggravate gastrointestinal discomfort, and may cause nausea and vomiting.
