Causes of Rhinitis in Children

Too-Yourhealth

Rhinitis is a common condition that causes inflammation of the nasal passages. It can be caused by a variety of factors, including allergies, infections, and irritants. In children, rhinitis is often caused by allergies to pollen, dust mites, or pet dander.

Allergic Rhinitis

Allergic rhinitis is the most common type of rhinitis in children. It is caused by an allergic reaction to an allergen, such as pollen, dust mites, or pet dander. When a child with allergic rhinitis comes into contact with an allergen, their body produces antibodies called immunoglobulin E (IgE). These antibodies bind to cells in the nose, which then release histamine and other inflammatory mediators. These mediators cause the blood vessels in the nose to dilate and the nasal passages to become inflamed.

Symptoms of allergic rhinitis include:

Sneezing

Runny nose

Itchy nose

Stuffy nose

Watery eyes

Scratchy throat

Infectious Rhinitis

Infectious rhinitis is caused by a virus, bacteria, or fungus. The most common cause of infectious rhinitis in children is the common cold virus. Other viruses that can cause infectious rhinitis include the flu virus and the adenovirus. Bacteria that can cause infectious rhinitis include Streptococcus pneumoniae and Haemophilus influenzae. Fungi that can cause infectious rhinitis include Aspergillus and Candida.

Symptoms of infectious rhinitis include:

Sneezing

Runny nose

Stuffy nose

Fever

Chills

Body aches

Headache

Fatigue

Irritant Rhinitis

Irritant rhinitis is caused by exposure to an irritant, such as smoke, dust, or chemicals. Irritants can damage the cells in the nose and cause inflammation. Symptoms of irritant rhinitis include:

Sneezing

Runny nose

Stuffy nose

Burning or stinging sensation in the nose

Itchy nose

Watery eyes

Diagnosis of Rhinitis

The diagnosis of rhinitis is based on the child's symptoms and a physical examination. The doctor may also order allergy testing to determine if the child has allergies.

Treatment of Rhinitis

The treatment of rhinitis depends on the cause.

Allergic rhinitis: Treatment for allergic rhinitis includes avoiding allergens, taking antihistamines, and using nasal sprays.

Infectious rhinitis: Treatment for infectious rhinitis includes rest, fluids, and over-the-counter medications. Antibiotics may be necessary if the infection is caused by bacteria.

Irritant rhinitis: Treatment for irritant rhinitis includes avoiding irritants and using nasal saline sprays.

Prevention of Rhinitis

There is no sure way to prevent rhinitis, but there are steps that can be taken to reduce the risk of developing the condition. These steps include:

Avoiding allergens

Washing hands frequently

Staying away from sick people

Getting vaccinated against the flu and other respiratory infections

Using a humidifier in the home

Keeping the home clean and free of dust and pet dander
