It is impossible to generalize how long it takes to recover from loss of taste and smell with a cold, but it usually recovers in about a week, and may take a little longer if combined with a serious infection.
Loss of taste in colds may be caused by edema of the mucous membrane in the olfactory region, neuritis due to viral infection, swelling of the mucous membrane of the nasal cavity so that the olfactory pigments are unable to reach the olfactory region, or due to the disease resulting in a slower metabolism, poor appetite, poorer mental condition, etc. The loss of smell is usually caused by edema of the nasal mucous membrane and increased nasal secretions. The loss of smell is usually caused by edema of the nasal mucosa and increased nasal secretions. It usually recovers gradually with the relief of colds.
Cold is a self-limiting disease and usually recovers in a week or so. Therefore, most patients recover their sense of taste and smell in about a week. Some patients are in better shape and recover more quickly, and may regain their sense of taste and smell in a shorter period of time. If the patient is in poor physical condition and has not been treated in time, resulting in a serious infection, it may take a slightly longer time to recover.
Patients are advised to pay attention to a light diet and maintain a good state of mind. If they cannot recover for a long time, they need to consult a doctor in time to avoid delaying their condition.
