It generally takes a few days for a baby to recover from severe wheezing depending on the disease the baby is suffering from, the degree of wheezing, and the medication used. There are many causes of wheezing in babies, such as respiratory diseases (e.g. pneumonia, bronchitis, etc.) and allergic diseases (e.g. allergic asthma, etc.) that may induce wheezing and other symptoms. If respiratory diseases cause severe wheezing with coughing and coughing, the symptoms of wheezing will generally disappear in about 7-10 days after prompt symptomatic treatment after the cause is clearly identified. In the case of allergic asthma caused by allergies, the wheezing symptoms will disappear within a few minutes to a few hours after the medication is administered and the allergens are removed. Therefore, the number of days it takes for a baby to recover from severe wheezing depends on the disease the baby has, the degree of wheezing, and the medication used. In addition, when asthma symptoms such as wheezing, recurrent cough and wheezing are detected, the baby should go to the pediatric department of the hospital for blood gas analysis, bronchial excitation test, lung function, chest imaging and other related examinations in time to avoid the eventual development of adult asthma due to untimely treatment or improper treatment, which may then cause impaired lung function or even risk of fatalities.
