Seasonal rhinitis, also known as allergic rhinitis with seasonal outbreaks, requires the identification of specific allergens for its prevention. This type of rhinitis is caused by allergies to seasonal factors, so it is necessary to visit an allergen testing center at an ENT (Ear, Nose, and Throat) department of a hospital to determine the specific allergens. Then, prior to the season, preventative measures can be taken to avoid contact with these allergens. Medications can be started one or two weeks in advance to alleviate the symptoms of rhinitis. Common medications include anti-allergy nasal steroids and other anti-allergy drugs such as antihistamines and leukotriene antagonists. Nasal steroids are typically administered via nasal spray once or twice a day, and during the prevention period, it can be sprayed once a day.

Difference between Allergic Rhinitis and Rhinitis

Allergic rhinitis and rhinitis are issues of a specific concept versus a broader concept. Allergic rhinitis is a type of rhinitis caused by a hypersensitivity reaction, which is an allergic response of the body leading to inflammation of the nasal passages. Rhinitis, however, includes allergic rhinitis as well as chronic rhinitis, hypertrophic rhinitis, vasomotor rhinitis, atrophic rhinitis, etc. Thus, it's a matter of differentiating between a more specific and a general concept. Clinically, it is particularly important to differentiate their diagnosis and treatment. For example, the primary treatment for allergic rhinitis is anti-allergy medication, whereas treatments for conditions like chronic and atrophic rhinitis are completely different. Therefore, it is crucial to differentiate these accurately in clinical practice to ensure the correct medication is used.

What causes rhinitis?

There are many causes of rhinitis in clinical settings, such as acute rhinitis, which is primarily due to infections, especially viral infections. Chronic rhinitis has many influencing factors, such as incomplete treatment of acute rhinitis leading to chronic conditions, or originating directly from chronic rhinitis. For instance, physical and chemical irritants, inappropriate use of medications in the nasal cavity, such as rhinitis medicamentosa caused by the use of nasal mucosa constrictors, and some inappropriate self-actions like habitual nose-picking, can all cause chronic rhinitis. Other forms of rhinitis, such as allergic rhinitis, are mainly caused by allergic factors. There is also vasomotor rhinitis, mainly due to inconsistent vasoconstriction, among other reasons. These are the main factors. (For specific medications, please follow the guidance of a professional physician and do not medicate blindly.)

Which is more serious, chronic rhinitis or allergic rhinitis?

Chronic rhinitis primarily involves inflammation of the nasal mucosa, submucosal tissues, nasal conchae, tympanic membrane, and even the bones. Allergic disease mainly involves allergic inflammation of the nasal mucosa. There is no clear distinction in severity between chronic rhinitis and allergic rhinitis. If chronic rhinitis tends towards an atrophic progression, then it is relatively serious. Allergic rhinitis, with its recurrent episodes, causes allergic cough and allergic asthma, which also signifies a relatively serious condition. Therefore, both chronic rhinitis and allergic rhinitis require active treatment, rather than distinguishing which one is more severe or which condition is milder. All issues should be actively treated.

Causes of Seasonal Rhinitis

Seasonal rhinitis, also known as allergic rhinitis, is considered an autoimmune disease, and its onset may be related to genetic factors. If direct relatives have allergic rhinitis, the likelihood of developing allergic rhinitis is relatively higher. Some patients are also related to environmental factors, such as frequent exposure to dust, pollen, and seafood, which also increases the likelihood of triggering allergic rhinitis. Clinical symptoms are numerous, with common ones including repeated itchy nose, runny clear nasal discharge, and sneezing. In terms of treatment, oral medications and nasal spray medications for anti-allergy treatment are commonly used, and regular follow-ups are needed to observe the effects. (Medication use should be under the guidance of a professional doctor.)

The difference between chronic rhinitis and allergic rhinitis

The differences between chronic rhinitis and allergic rhinitis are quite significant. Firstly, we need to consider the causes of the diseases. Allergic rhinitis is mainly caused by the body's own immune response, primarily due to allergens the body encounters externally, which trigger this immune response. Chronic rhinitis, on the other hand, is primarily associated with local inflammation of the nasal mucosa and turbinates, and generally, it is not directly related to the body's own immune system. Another difference lies in the symptoms. The main symptoms of chronic rhinitis include nasal congestion and runny nose, with some patients possibly experiencing headaches or dizziness. In contrast, symptoms of allergic rhinitis mainly include itchy nose, sneezing, and clear nasal discharge, with some patients possibly experiencing nasal congestion. In such cases, it is necessary to visit an otolaryngologist, allowing an experienced doctor to make a diagnosis, supplemented by additional diagnostic tests.
