In general, symptoms of allergic rhinitis in children include nasal itching, sneezing, runny nose, nasal congestion, and reduced sense of smell. Detailed explanations are as follows:
1. Nasal Itching: When a child's nasal mucosa comes into contact with allergens such as pollen or dust mites, the immune system identifies them as harmful substances and initiates an immune response, resulting in a sensation of nasal itching.
2. Sneezing: Paroxysmal or continuous sneezing is a typical manifestation of allergic rhinitis. Each episode may involve no fewer than five sneezes and can even reach ten or dozens.
3. Runny Nose: Allergic reactions cause blood vessels in the nasal mucosa to dilate and become more permeable, allowing fluid and certain immune cells from the bloodstream to seep into the nasal tissues, forming a runny nose. The nasal discharge is usually clear and watery, but it may thicken due to nasal blockage or secondary infection.
4. Nasal Congestion: During an allergic reaction, the nasal mucosa becomes congested and swollen, narrowing the nasal passages. Children may experience congestion in one or both nostrils, with varying severity that can affect sleep and daily activities.
5. Reduced Sense of Smell: Allergic reactions may directly affect the function of olfactory receptors, reducing their ability to detect odors, which leads to a diminished sense of smell. Some children may temporarily lose their sense of smell due to allergic rhinitis.
For daily diet, it is recommended to eat light meals, avoid spicy and cold foods, consume more vegetables and fruits to enhance immunity. Nasal irrigation with normal saline daily can help clear secretions and relieve discomfort in children.
