What does nasal catarrh mean

Nasal catarrh is actually a type of rhinitis and swelling of the nasal mucosa, which can be divided into acute rhinitis and chronic rhinitis. However, we all know that the occurrence of this condition will have an impact on life and health, so we need to pay attention to correct and scientific treatment.

1. Swelling of the nasal mucosa, also known as nasal mucosal enlargement, is more common in rhinitis. It is a swelling caused by irritation of the nasal mucosa by inflammation in the nasal cavity. In terms of pathological changes of nasal mucosa, there are chronic simple rhinitis, chronic hypertrophic rhinitis, caseous rhinitis, atrophic rhinitis, etc. In terms of the rapidity of onset and the length of the course of the disease, it can be divided into acute rhinitis and chronic rhinitis.

2. When rhinitis develops to a certain extent, when the vascular lesions of the nasal mucosa are mainly characterized by microvascular dilation and increased permeability, it manifests as pale edema; when the lesions of the nasal mucosal blood vessels are mainly characterized by dilation of venules and cavernous sinuses, it manifests as swelling. Swelling or edema of the nasal mucosa is one of the main causes of nasal congestion.

3. If the swelling of the nasal mucosa (rhinitis) is not effectively treated, it will seriously affect people's normal life, mainly manifested in symptoms such as dizziness, fatigue, low fever, excessive nasal discharge, blood in the mucus, etc. If it continues for a long time, it may even cause cancer.

In addition, some rhinitis, although it develops slowly and lasts for a long time, has specific causes and therefore has specific names, such as allergic rhinitis (also known as allergic rhinitis) and drug-induced rhinitis.
