What causes a white foreign object on the side of the throat, and what should I do?

Generally speaking, the term "throat" refers to the pharynx. White foreign bodies on the edge of the throat may be related to causes such as food residue, oral mucosal shedding, purulent tonsillitis, pharyngeal candidiasis, and diphtheria. It is recommended to seek timely medical advice and receive treatments such as general care and medication under a doctor's guidance. The detailed analysis is as follows:

1. Food Residue

During eating, some food residue may adhere to the edges of the pharynx, forming white foreign bodies. It is recommended to rinse the mouth after meals and use dental floss to clean between teeth to reduce food residue retention.

2. Oral Mucosal Shedding

The normal metabolism of oral mucosa leads to cell shedding, and some of these shed cells may accumulate at the edge of the throat, forming white foreign bodies. Maintaining good oral hygiene and avoiding excessive use of irritating oral care products are recommended.

3. Purulent Tonsillitis

Purulent tonsillitis is usually caused by bacterial infections such as hemolytic streptococcus. Bacterial infection causes swelling and congestion of the tonsils, with white or yellowish-white purulent secretions on the surface. Symptoms typically include sore throat, difficulty swallowing, fever, and others. Treatment should follow medical advice regarding the use of medications such as Penicillin V potassium tablets, Cefixime dispersible tablets, and Compound Chlorhexidine Gargle.

4. Pharyngeal Candidiasis

Pharyngeal candidiasis is usually caused by Candida infection. Fungal infection results in white pseudomembranes covering the pharyngeal mucosa, sometimes appearing as punctate or patchy distributions. Symptoms generally include throat discomfort, foreign body sensation, and dryness. Treatment should follow medical advice regarding the use of medications such as Ketoconazole cream, Fluconazole capsules, and Cefradine capsules.

5. Diphtheria

Diphtheria is usually caused by infection with Corynebacterium diphtheriae. Bacterial infection causes congestion and swelling of the pharyngeal mucosa, with a layer of gray-white pseudomembrane formed on the surface that is difficult to wipe away. Symptoms may also include fever, fatigue, and sore throat. Treatment should follow medical advice regarding the use of medications such as Erythromycin enteric-coated capsules, diphtheria antitoxin, and injectable Sodium Penicillin G.

Maintaining good daily habits and mindset, along with regular dental check-ups, is important for timely detection and management of throat issues.
