What are the main causes of recurrent pharyngitis?

Pharyngitis is a relatively common type of inflammation, especially chronic pharyngitis, which is prone to recurring and is quite harmful to patients. In severe cases, it can cause fever and easily lead to infection of adjacent organs and tissues. There are many causes of pharyngitis, such as colds, systemic diseases, mental stress, and pathogenic microorganisms, which can easily cause recurrent pharyngitis.

1. Diseases of adjacent organs:

Acute or chronic inflammation of the nasal cavity, sinuses, mouth, teeth, gums, larynx, trachea, bronchi and other adjacent organs, which invade the pharynx along the mucosa, submucosal tissue, local lymph and blood circulation, or repeated stimulation of the pharynx by inflammatory secretions, or forced mouth breathing due to obstruction of breathing due to nasal disease, can all lead to pharyngitis.

2. Systemic diseases:

Allergic constitution or systemic diseases such as rheumatic fever, gout, diabetes, heart disease, anemia, nephritis, bronchitis, emphysema, bronchiectasis, tuberculosis, cirrhosis and malnutrition and constipation caused by digestive system diseases can lead to a decrease in overall resistance and impaired blood circulation in the pharynx, which in turn causes pharyngitis.

3. Pathogenic microorganisms:

The main pathogenic factors of pharyngitis include bacteria, viruses, spirochetes, rickettsia, etc., which can come directly from the air and diet, or indirectly from blood circulation and lymphatic circulation, all of which can lead to the occurrence of pharyngitis.

4. Physical or chemical stimulation:

Talking too much, liking spicy or hot food, smoking and drinking excessively, and being exposed to air pollution such as chemical gases and dust can all damage the pharyngeal mucosal epithelium and glands. Destroys the local defense system; can also cause pharyngitis.

5. Climate and seasonal factors:

Coldness can cause pharyngeal mucosal blood vessels to contract, the number of phagocytes to decrease, and local resistance to decline; dryness can affect pharyngeal mucus secretion and ciliary motility, reducing the cleaning and humidifying effects of the air, and directly causing irritation and damage to the pharyngeal mucosa; the climate changes greatly in winter and spring, and the indoor air circulation is poor, which can easily lead to a decrease in resistance and invasion of pathogenic microorganisms, thereby causing pharyngitis.
