Tracheal diverticulum does not usually get better with abdominal breathing. If the patient is asymptomatic with tracheal diverticulum, no treatment is needed. If the tracheal diverticulum is combined with infection, drug treatment is needed, and if necessary, surgical treatment. Tracheal diverticulum is mainly caused by congenital tracheal dysplasia, weak abdominal wall, etc., and abdominal breathing refers to increase the diaphragm’s range of motion, reduce thoracic cavity movement, and improve lung ventilation, but it is generally ineffective for the improvement of tracheal diverticulum, so the patient’s abdominal breathing can not make the condition better. Generally when patients with tracheal diverticulum are asymptomatic, no treatment measures can be taken. If tracheal diverticulum is combined with bacterial infection, antibiotics such as cefixime and cefuroxime are needed under the guidance of a doctor. In severe cases of tracheal diverticulum, surgery is required to remove the diseased area. Patients who are considering tracheal diverticula are advised to seek prompt medical attention, and the doctor will choose appropriate measures to treat the patient’s condition. In addition, patients should keep the indoor environment clean and should not go to environments with heavy air pollution. Patients should eat less spicy food such as chili and mustard in their diet, and can eat light food such as tomatoes and green vegetables.
