最常见的一种情况是胃食管反流（简称GERD）导致食管腺癌。

So gastroesophageal reflux disease, or GERD, is when stomach acid flows back into the esophagus.

因此，胃食管反流病，即GERD，指由于过多的胃酸反流回食管而引起的烧心、反酸等症状。

Ok, now the most common symptom of chronic gastroesophageal reflux disease is pyrosis, also called heartburn, which is a burning pain in the chest, just behind behind the breastbone.

慢性胃食管反流病最常见的症状是胃灼热，也叫烧心，就是胸骨后烧灼感。

Reflux laryngitis is another cause of chronic laryngitis and develops in people with severe gastroesophageal reflux disease where acid from the stomach goes all the way up the esophagus into the pharynx.

反流性喉炎是另一个慢性喉炎的病因，见于严重胃食管反流病的患者：胃酸通过食管，向上进入咽部。

Alright, as a quick recap, gastroesophageal reflux disease, or GERD, is a condition where a decreased tone of the lower esophageal sphincter causes an excessive amount of stomach acid to flow back into the esophagus.

得！快速回顾一下：胃食管反流病（即GERD）是一种食管下括约肌张力下降导致过多胃酸反流回食管的疾病。
