Allergic rhinitis that is very severe and affects sleep must be caused by allergic rhinitis that is not treated in a timely manner or not maintained with maintenance treatment. It may be that rhinitis causes sinusitis, or even some children have adenoid hypertrophy in addition to allergic rhinitis, at which point it can affect sleep. The impact on sleep depends on the extent of the impact on sleep and whether there is a sleep disorder causing hypoxia, which should be determined by a sleep EEG. If there is adenoid hypertrophy, see if it exceeds a certain percentage, for example, more than 70%, what does it mean? Because of the narrowing of the airway caused by adenoid hypertrophy, a blockage of more than 70% can be an indication for surgery. If the simple allergic rhinitis is not required to do surgery, even if the surgery is done, it is meaningless. Therefore, long-term medication must be used. One of the medications for allergic rhinitis is hormone inhalation, hormone spray spray, such as endosulfan, reno-cort, co-sulfan, are commonly used. There is also oral montelukast, which can be used in combination. In addition to this, you can use some anti-allergy drugs, such as loratadine, cetirizine, etc. In short, persistent treatment and long-term treatment are necessary to improve the quality of life of your child. It is important to see when it really affects sleep, and the surgery must be done.
