Overgrowth of uvula may be due to chronic inflammatory stimulation of neighboring organs, developmental abnormalities, etc. A few patients may not have any symptoms, and some of them may cause foreign body sensation, cough, nausea, and change of voice. 1. Foreign body sensation: it can cause discomfort or foreign body sensation in the pharynx, and often nausea and vomiting, especially obvious when checking the pharynx and eating. When the mouth is opened wide and deep breathing is done (at this time, the soft palate is lifted and the pharyngeal isthmus is enlarged), the foreign body sensation can disappear, and then reappear after the mouth is closed. 2. Cough: patients also often have paroxysmal cough and voice changes, cough is more likely to occur when lying down, mostly due to irritation of the posterior wall of the pharynx by the uvula. Examination of patients found that the uvula is too long, you can actively go to the hospital to check the diagnosis, follow the doctor’s instructions to standardize the treatment.
