The recovery time for chronic pneumonia varies individually, depending on the severity of the disease and physical fitness. If the symptoms are mild and the patient is in good health, only a mild cough, white mucous sputum, white blood cells and calcitoninogen are not high, and a few foci of infection can be observed in the chest X-ray, active anti-inflammatory and anti-infective treatment can be given, and the recovery period is about 1 week. If the symptoms are relatively severe, with high fever, chills, massive cough, yellow pus sputum, abnormally high white blood cells and calcitoninogen, along with chest tightness and shortness of breath, the treatment time is relatively long at this time, and it usually takes about half a month of active anti-infection treatment to gradually recover. In addition, during the recovery period of chronic pneumonia, patients should pay attention to balanced nutrition, more intake of fresh vegetables and fruits, appropriate exercise to enhance physical fitness, and avoid catching a cold, which will help reduce the recurrence of the disease.
