Why do you feel nauseous and vomit when you have a cold?

The symptoms of nausea and vomiting when the stomach is uncomfortable during a cold need to be considered gastrointestinal cold, which is a very specific type of upper respiratory tract infection, mainly due to a decrease in the body’s resistance to infection by viruses, bacteria and other pathogens, causing congestion, edema and exudation of inflammatory secretions from the mucosa of the upper respiratory tract. The lymph nodes of the upper respiratory tract mucosa can also be involved causing inflammation, which through the lymphatic system can spread to the digestive tract, such as the lymph nodes of the gastrointestinal tract thus causing inflammation. Therefore, gastrointestinal reactions will occur, manifesting as relatively uncomfortable stomach with nausea and vomiting. Generally, clinical treatment to protect the gastrointestinal tract, such as B-complex vitamins and patchouli, can be given.
