What causes the feeling of something blocking the throat?
Generally, the throat refers to the pharynx. A sensation of something blocking the throat may be caused by pharyngeal dryness, pharyngeal muscle tension, chronic pharyngitis, reflux pharyngitis, or tonsillar hypertrophy. If discomfort occurs, timely medical consultation is recommended. Detailed explanations are as follows:

1. Pharyngeal Dryness
Pharyngeal dryness may occur due to insufficient moisture to the oral and throat mucous membranes, leading to dryness of the mucosal surface and causing a foreign body sensation. This commonly occurs after prolonged speaking, inadequate water intake, or in dry environments. Maintain adequate hydration, use a humidifier, or place a water basin indoors to increase air humidity.
2. Pharyngeal Muscle Tension
Pharyngeal muscle tension may be caused by anxiety, stress, or unhealthy lifestyle habits (such as prolonged looking down at a mobile phone), causing contraction of the throat muscles and resulting in a foreign body sensation. Maintain good lifestyle habits, reduce prolonged head-down activities, and perform relaxation exercises to relieve pharyngeal muscle tension.
3. Chronic Pharyngitis
Chronic pharyngitis may be caused by repeated episodes of acute pharyngitis, long-term irritation from smoking and alcohol consumption, or inhalation of harmful gases or dust. The inflammation leads to congestion and edema of the pharyngeal mucosa, causing a foreign body sensation, possibly accompanied by symptoms such as throat pain, dryness, and burning. Local treatments, such as compound borax mouthwash, cydiiodine lozenges, and menthol throat tablets, should be used according to medical advice.
4. Reflux Pharyngitis
Reflux pharyngitis may occur when stomach acid refluxes to the throat, irritating the pharyngeal mucosa and causing inflammation. Acid irritation causes a foreign body sensation, often accompanied by a burning feeling. Symptoms may also include hoarseness, retrosternal pain, and coughing. Treatment may include medications such as omeprazole enteric-coated capsules, rabeprazole sodium enteric-coated tablets, and domperidone tablets, as advised by a physician.
5. Tonsillar Hypertrophy
Tonsillar hypertrophy is usually caused by repeated episodes of chronic tonsillitis, infection, or allergic reactions. The enlarged tonsils occupy space in the throat, causing a foreign body sensation. It may also lead to difficulty swallowing, breathing difficulties, and headaches. Medications such as amoxicillin capsules, cefradine capsules, and roxithromycin capsules may be used under medical guidance for treatment.
To prevent this symptom, it is recommended to maintain adequate hydration in daily life to avoid pharyngeal dryness. At the same time, avoid prolonged exposure to harmful gases or dusty environments to reduce throat irritation.
