Whether an infection in the right lung is serious depends on the condition, and also considers the patient’s age, resistance, and the presence of underlying diseases. A limited infection is not considered serious; if there are serious complications, it may be more serious. Most right lung infections are caused by viruses, bacteria, mycoplasma, fungi, tuberculosis and other infections. If the lesion is more limited and the systemic symptoms are not obvious, the infection can be absorbed after active treatment, which is usually not considered serious. If the disease is prolonged and there are serious complications, such as lung abscess, pleural effusion, thoracic adhesions, pyothorax, septicemia, etc., it may be more serious. If the patient is older, has lower resistance, has multiple chronic diseases, such as diabetes, or is a tumor patient, it is also not conducive to recovery from the disease, and may cause infectious shock or bacteremia, which is usually more serious as well. If you suffer from the above diseases, you need to consult a regular hospital in time, and cooperate with the doctor to improve the examination and standardize the treatment.
