Colds accompanied by headache and nausea that prompts a feeling of wanting to vomit can be symptoms caused by a gastrointestinal type of cold, leading to dizziness, headache, nausea, and other discomforts. At this time, one can take some anti-cold medications combined with medications that aid digestion and alleviate symptoms. It is also necessary to take medicines that regulate the stomach and intestines for treatment. Make sure to eat smaller meals more frequently and not to eat too much at one time. Additionally, under the guidance of a doctor, one can take some antiemetic drugs to relieve nausea and the urge to vomit. It's beneficial to consume more liquid or soft foods, such as millet porridge, soft noodles, or vegetable soup. Moreover, it's important to eat slowly and chew thoroughly to fully digest the food and avoid overburdening the intestines and causing symptoms of indigestion.
