Nasal congestion is a symptom that usually requires treatment for the disease causing it, not just the symptom. Diseases that cause nasal congestion include chronic hypertrophic rhinitis, sinusitis, nasal swelling, etc. They can be treated with oral medications, nasal sprays, and surgery. 1. Chronic hypertrophic rhinitis: Decongestants can be used to shrink blood vessels and reduce the swelling of the nasal mucosa, and common drugs such as hydroxymetazoline. If the drug treatment is not effective, it is necessary to carry out partial resection of the inferior turbinate under the guidance of the doctor. 2. Sinusitis: Decongestants such as ephedrine can be used to relieve nasal congestion. If the nasal secretion is sticky and difficult to eliminate, eucalyptus-pinocampus enteric capsule can be used to promote the discharge of mucus. 3. Nasal swelling: new organisms in the nasal cavity can block the nasal cavity, such as nasal polyps, nasal involutional papilloma, etc., should go to the hospital in time to perform surgical removal of the swelling treatment. It is recommended that patients seek medical treatment in time and cooperate with doctors to find out the causes, the above drugs should be used as prescribed by doctors.
