Colds are a common illness and can lead to symptoms of nausea and vomiting. On one hand, some people experience a gastrointestinal type of cold, characterized by stomach discomfort and possibly even diarrhea, which can lead to nausea and vomiting. On the other hand, colds can also cause fever, and the fever can affect the function of the gastrointestinal tract, resulting in nausea and vomiting. Therefore, there is no need to panic if these symptoms occur after catching a cold; some medications can be used to treat the symptoms accordingly. At the same time, it is important to rest, avoid getting chilled, drink plenty of water, and eat a light diet to facilitate recovery. (Medication should be used under the guidance of a physician.)
