The specific recovery time of cold and loss of voice is related to the accompanying symptoms, their own resistance and usual care, most of the patients with cold and loss of voice can be relieved after 2-3 days of treatment, and the treatment can be recovered in about 7 days. Cold loss of voice is mostly due to pathogens infecting the upper respiratory tract, causing congestion and edema of the throat and vocal cords, and clinically, anti-infective treatment programs are often used, and the inflammatory reaction of the throat and vocal cords can be relieved after 2-3 days of treatment, and the inflammation of the area can be completely cured in about 7 days of treatment. However, if the patient is accompanied by high fever and other symptoms, indicating that their own resistance is weak, not enough to resist the pathogens in the body, then the inflammation relief time will be extended. In addition, whether or not to pay attention to care after the cold loss of voice will also affect the recovery time, such as frequent talking will cause the vocal folds to vibrate, can not rest, thus aggravating the vocal folds edema. Therefore, if the patient has lost his voice after a cold, he should drink more warm water to speed up the blood circulation of the body, prohibit the consumption of spicy and stimulating food, and need to quit smoking and alcohol.
