Why does nasal congestion with runny nose and difficulty breathing through the nose cause nausea, and what should be done about it?

Nasal congestion with runny nose and nausea when breathing through the nose may be related to upper respiratory tract infections, allergic rhinitis, sinusitis, or other causes. Symptoms can be improved through medication and daily care. Specific analyses are as follows:

1. Upper Respiratory Tract Infection

Upper respiratory tract infections are usually caused by viruses, which can lead to nasal mucosal congestion, swelling, and increased secretions, resulting in nasal discomfort. Patients may take medications such as compound paracetamol and amantadine capsules or ammonium caffeine yellow敏capsules according to medical advice.

2. Allergic Rhinitis

Allergic rhinitis is typically triggered by allergens such as pollen, dust mites, pet dander, or others, which may irritate the nasal mucosa and blood vessels, causing symptoms like sneezing and nasal itching. Patients can use topical treatments such as naphazoline hydrochloride nasal drops or oxymetazoline hydrochloride nasal drops.

3. Sinusitis

Sinusitis refers to inflammation of the sinuses, which may increase nasal mucosal secretions and block sinus passages, leading to pressure and pain. Patients may use ephedrine hydrochloride nasal drops or compound menthol nasal drops as directed by a physician.

In addition to the common causes mentioned above, symptoms may also be associated with deviated nasal septum, chronic pharyngitis, or other conditions. Patients should seek timely medical evaluation to determine the underlying cause and receive targeted treatment.
