What causes a foreign body sensation in the throat and esophagus, and what should I do?

Generally, the term "throat" refers to the pharynx. A foreign body sensation in the throat and esophagus may be related to pharyngeal mucosal irritation, physiological narrowing of the esophagus, chronic pharyngitis, reflux esophagitis, esophageal diverticula, and other causes. It is recommended to seek timely medical consultation and undergo general treatment or medication under the guidance of a physician. Detailed explanations are as follows:

1. Pharyngeal Mucosal Irritation

When the pharyngeal mucosa is irritated by smoke, cold air, or other external factors, it may cause a temporary inflammatory reaction, leading to mucosal swelling and a foreign body sensation. It is recommended to keep indoor air humidified and avoid prolonged exposure to dry environments.

2. Physiological Narrowing of the Esophagus

There are physiologically narrow areas in the esophagus, such as the esophageal inlet and the aortic arch. When food or saliva passes through these narrow areas, it may cause a mild sensation of a foreign body. It is advisable to chew food thoroughly and avoid eating too quickly or consuming hard foods.

3. Chronic Pharyngitis

Chronic pharyngitis is usually caused by recurrent acute pharyngitis or long-term irritation from smoking and alcohol consumption. Inflammation causes congestion and edema of the pharyngeal mucosa and hyperplasia of lymphoid tissue, leading to a foreign body sensation. Symptoms often include dryness, pain, and coughing in the throat. Medications such as Yinhuang Tablets, Pharyngitis Tablets, and Compound Borax Mouthwash may be used under a physician's guidance.

4. Reflux Esophagitis

Reflux esophagitis is typically caused by the backflow of gastric acid or stomach contents into the esophagus. The refluxed material irritates the esophageal mucosa, causing inflammation and swelling, which leads to a foreign body sensation. Symptoms often include acid regurgitation, belching, and abdominal distension. Treatment may involve medications such as Omeprazole Enteric-coated Capsules, Hydrotalcite Chewable Tablets, and Domperidone Tablets, as directed by a physician.

5. Esophageal Diverticula

Esophageal diverticula are often associated with dysfunction of esophageal motility. Food residue or accumulated secretions within the diverticulum can irritate the esophageal mucosa, causing a foreign body sensation. Additional symptoms may include dysphagia, retrosternal pain, and food regurgitation. Treatment may involve medications such as Amoxicillin Capsules, Cefradine Capsules, and Colloidal Bismuth Pectin Capsules, under medical supervision.

In daily life, maintaining healthy lifestyle habits and avoiding prolonged states of tension and anxiety can help alleviate physical discomfort.
