There are many reasons for colds to have no taste in food, which may be caused by viruses invading the taste nerves, nasal congestion, medications and other factors. 1. Viruses invade the taste nerve: viral infections cause colds, such as coxsackievirus, adenovirus, syncytial virus, etc. If viruses invade the taste nerve after infection, it will lead to a temporary loss of taste. If the virus violates the gustatory nerve after infection, it will lead to a short-term loss of taste, and the sense of taste will gradually recover after the cold gets better. 2. Nasal congestion: Nasal congestion caused by colds can lead to olfactory impairment, the nasal cavity has become congested and edematous, resulting in nasal congestion. The nasal cavity becomes congested and edematous, resulting in nasal congestion. There is no way for food odors to enter the olfactory region, so this can lead to olfactory malfunction. 3. Drugs: some drugs stimulate the gastrointestinal tract, such as aspirin, acetaminophen, etc., the use of drugs will stimulate the gastric mucosa, thus affecting the appetite, and there is a transient loss of taste. When there is no taste of cold food, it is recommended to consult a doctor in a timely manner, follow the doctor’s instructions for further examination, with the help of the doctor to clarify the cause, and targeted treatment or treatment.
