What's the burning sensation in the esophagus?

Esophageal burning sensation refers to a burning sensation or heat sensation behind the sternum or in the upper abdomen, which may be caused by acid reflux, esophageal disease, eating habits, other factors, etc. 1. Acid reflux Acid reflux is one of the most common causes. When the sphincter function between the stomach and esophagus is weakened or dysregulated, gastric acid is easy to reflux into the esophagus, stimulating the esophageal mucosa, causing burning sensation. This may be related to eating habits, obesity, increased abdominal pressure, certain drugs and other factors. 2. Esophageal diseases such as esophagitis, esophageal ulcer, etc., the above diseases themselves will lead to esophageal mucosa damage, prone to burning sensation. 3. Eating habits Eating too fast, too much, too full, or eating spicy, greasy, irritating foods, acidic foods, etc., may stimulate increased gastric acid secretion or lead to delayed gastric emptying, thus causing esophageal burning. 4. Mental factors in a long-term state of tension, anxiety, stress, may affect the normal function of the gastrointestinal tract, leading to abnormal gastric acid secretion and heartpower disorders, increasing the risk of esophageal burning sensation. 5. Other factors Some diseases such as peptic ulcer, stomach tumor, etc. may also indirectly lead to esophageal burning sensation. In addition, pregnancy, smoking, drinking, etc. may also be related to esophageal burning sensation. If esophageal burning sensation occurs frequently, seriously affects the quality of life, or is accompanied by other symptoms such as dysphagia, chest pain, nausea, vomiting, etc., you should seek medical attention in time for detailed examination, such as gastroscopy, esophageal pH monitoring, etc., to clarify the cause and take appropriate treatment measures.
