What does it mean when there is yellow nasal discharge in the nose upon waking up?
Yellow nasal discharge upon waking in the morning may be caused by various factors such as chronic nasal vestibulitis or nasal vestibule eczema. It is recommended to seek medical attention promptly and identify the underlying cause under the guidance of a healthcare professional before initiating treatment.

1. Dry Air
When indoor air is excessively dry, moisture from the nasal mucosa easily evaporates, causing nasal secretions to become thick and sticky. Dust and other impurities in the nasal cavity are more likely to adhere, forming yellow nasal discharge. Using a humidifier to maintain indoor humidity between 40% and 60%, or placing water basins indoors to increase evaporation, can help alleviate this condition.
2. Dietary Factors
Consuming excessive spicy, greasy, or irritating foods may lead to internal "heat" buildup, increasing nasal secretions and turning them yellow. Adjust your diet by eating more light, vitamin-rich foods such as fresh vegetables and fruits, drinking plenty of water, and reducing intake of spicy and oily foods.
3. Chronic Nasal Vestibulitis
Nasal vestibulitis refers to acute or chronic inflammation of the skin in the nasal vestibule. In addition to yellow discharge, patients may experience itching. Treatment may include soaking or rinsing with warm normal saline or boric acid solution for astringent effects; warm compresses may also provide some relief.
4. Sinusitis
Sinusitis involves inflammation of the sinus mucosa, often caused by bacterial infection. The inflammatory response leads to the production of large amounts of purulent secretions within the sinuses, which drain backward into the nasal cavity, resulting in yellow nasal discharge. This condition is commonly accompanied by symptoms such as nasal congestion and headache. Medications used for treatment include eucalyptus oil-pinen capsules (enteric-coated soft capsules), amoxicillin-clavulanate potassium tablets, and mometasone furoate nasal spray.
5. Nasal Vestibule Eczema
Nasal vestibule eczema is a type of skin lesion occurring in the nasal vestibule, characterized by an inflammatory skin reaction with significant exudation and diverse rash presentations. Patients may apply topical tacrolimus ointment or take desloratadine citrate tablets orally as directed by a physician.
In daily life, maintain a light diet and avoid spicy or irritating foods such as garlic, hot pot, and mustard. Ensure adequate rest and avoid excessive fatigue to prevent adverse effects on overall health.
