Thickening of the mucous membrane of the throat may be related to chronic simple pharyngitis, chronic hypertrophic pharyngitis and reflux pharyngitis.
1. Chronic simple pharyngitis: acute simple pharyngitis recurrent episodes are often the cause of the disease, the lesions are mainly in the mucous membrane layer, manifested as chronic congestion of the pharyngeal mucosa, there are more lymphocyte infiltration around the blood vessels, but also can be seen in the infiltration of leukocytes and plasma cells. Mucosal and submucosal connective tissue hyperplasia. Mucous glands can be hypertrophied, hypersecretory function, increased mucus secretion.
2. Chronic hypertrophic pharyngitis: under the stimulation of adverse physical and chemical factors and chronic inflammation of the upper respiratory tract, chronic simple pharyngitis can often develop into this disease. Mucosal congestion and thickening, mucosa and submucosa have more extensive connective tissue and lymphoid tissue hyperplasia, lymphoid tissue hyperplasia protrudes around the mucous glands, which is manifested as multiple granular bulges on the posterior wall of the pharynx, and sometimes even fused into a piece.
3. Reflux pharyngitis: gastric contents reflux to the throat, corrosion, damage to the mucosa of the throat, stimulate mucosal vasodilatation, tissue exudate increase, mucosal hyperplasia can occur.
Thickening of the mucous membrane of the throat is due to a number of reasons, it is recommended to actively seek medical attention, systematic examination to clarify the cause of the disease.
