Why do esophageal cancer patients feel food getting stuck and experience vomiting of mucus when eating, and what should be done about it?

In general, esophageal cancer patients may experience symptoms of food pushing upward and spitting mucus during meals, which could be related to improper eating habits, weakened swallowing function, esophagitis, gastroesophageal reflux disease (GERD), or hiatal hernia. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Improper Eating Habits

Spicy, greasy, or excessively hot foods can irritate the esophageal mucosa. If a patient frequently consumes spicy, irritating, or overly hot foods during illness, it may exacerbate inflammatory responses, leading to food and mucus reflux. It is advisable to adjust dietary habits by choosing light, easily digestible foods such as white rice porridge or soup noodles. Additionally, avoid alcohol consumption and smoking to reduce irritation to the esophagus.

2. Weakened Swallowing Function

Esophageal cancer may damage esophageal muscles or nerves, thereby impairing swallowing function. During eating, reduced peristalsis and contractile function of the esophagus can cause food and liquids like saliva to stagnate within the esophagus, resulting in sensations of upward pressure and mucus regurgitation. Patients should choose easy-to-swallow foods, maintain a balanced diet, and adopt a pattern of eating small meals more frequently.

3. Esophagitis

Esophagitis commonly accompanies esophageal cancer. Inflammation stimulates the esophageal mucosa, increasing secretions and resistance to food passage. These secretions may reflux into the mouth along with food during eating, causing the sensation of food moving upward and mucus expulsion. Other typical symptoms include esophageal spasms and discomfort during eating. Patients may follow medical advice to use medications such as colloidal bismuth pectin capsules, lansoprazole tablets, or omeprazole enteric-coated capsules for treatment.

4. Gastroesophageal Reflux Disease (GERD)

GERD refers to the backflow of stomach contents into the esophagus due to dysfunction of the lower esophageal sphincter, irritating the esophageal mucosa and causing sensations of food rising upward and mucus vomiting during meals. Esophageal cancer patients, whose esophageal function is already compromised, are more prone to developing GERD. Common accompanying symptoms include retrosternal burning sensation, belching, and dysphagia. Under medical supervision, patients may take medications such as mosapride citrate tablets, ranitidine tablets, or rabeprazole sodium enteric-coated tablets.

5. Hiatal Hernia

A hiatal hernia occurs when part of the stomach in the abdominal cavity protrudes through the esophageal hiatus of the diaphragm into the chest cavity. This displaces the lower esophageal sphincter abnormally, weakening the barrier that prevents acid reflux and making the sensation of food pushing upward more pronounced. Other common symptoms include chest pain, belching, and nighttime coughing. Patients may follow their doctor's instructions to use medications such as domperidone tablets, sucralfate chewable tablets, or potassium citrate bismuth capsules.

It is recommended that patients develop healthy lifestyle habits during recovery, including eating smaller meals more frequently and chewing food thoroughly. Consuming more fresh vegetables and fruits can also contribute to overall health.
