Allergic pneumonia symptoms are mainly divided into early symptoms, such as wheezing, runny nose, etc.; middle and late symptoms, such as nausea and vomiting, fever and cyanosis.
1. Early symptoms: the early symptoms of allergic pneumonia usually start 3~6 hours after the patient inhaled the sensitizing factor. As the sensitizing factor will stimulate the bronchial mucosa, resulting in mucosal edema and increased secretion, the patient will experience symptoms such as wheezing, runny nose, dry cough, etc., and some of the patients are accompanied by chest pain, and then they should be detached from the allergen immediately, and seek medical treatment in a timely manner.
2. Middle and late symptoms: If the condition is not controlled in time, the sensitizing factor can lead to infection, stimulate gastrointestinal peristalsis and gastrointestinal reactions such as nausea and vomiting, diarrhea and other gastrointestinal reactions, accompanied by systemic fever symptoms. Continuous edema can lead to airway obstruction, gas exchange is impaired, the patient hypoxia can be manifested as cyanosis of lips and fingers and toes, and in severe cases, anaphylactic shock can be induced.
To summarize, patients should go to the hospital for treatment immediately to control the development of the disease and to avoid life-threatening situations.
