What causes throat congestion?

If your throat is congested, you should pay attention to whether it is caused by some bacteria and microorganisms. In particular, acute pharyngitis is prone to these symptoms. Also, if you are not careful about your diet and often eat spicy and irritating foods, it may cause throat congestion.

1. Pathogenic microorganisms: including bacteria, viruses, spirochetes, rickettsia, etc., are the main pathogenic factors of acute pharyngitis, which can come directly from the air and diet, or indirectly from the blood circulation and lymphatic circulation.

2. Physical or chemical stimulation: Talking too much, eating spicy or hot food, excessive smoking and drinking, chemical gas, dust and other air pollution can all damage the pharyngeal mucosal epithelium and glands. Destroy local defense systems.

3. Climate and seasonal factors: Cold weather can cause pharyngeal mucosal blood vessel contraction, reduce the number of phagocytes, and decrease local resistance; dryness can affect pharyngeal mucus secretion and ciliary peristalsis, reduce the cleaning and humidifying effects of the air, and directly cause 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.

4. Diseases of adjacent organs: acute and chronic inflammation of the nasal cavity, sinuses, oral cavity, 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 obstruction of breathing due to nasal disease and forced mouth breathing, can all lead to pharyngitis.

5. 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 decreased overall resistance and impaired blood circulation in the pharynx, which in turn causes pharyngitis.

6. Other common factors that induce pharyngitis include excessive fatigue, mental stress, and lack of sleep.
