Acid Reflux (GERD)
Reflujo ácido
Also: Reflujo gastroesofágico (regional variant)
What it means
Acid reflux is another name for gastroesophageal reflux (GER), which happens when stomach contents come back up into the esophagus, the tube that carries food from the mouth to the stomach. It happens when the muscle at the end of the esophagus does not close properly, and it may cause heartburn, a burning feeling in the chest or throat. Having reflux once in a while is common. Gastroesophageal reflux disease (GERD) is the more severe, long-lasting condition in which reflux causes repeated, bothersome symptoms or leads to complications over time.

| Other Spanish terms | Where it is used | Note |
|---|---|---|
| reflujo gastroesofágico (RGE) | General | The formal medical name; MedlinePlus en español uses it as its topic title and abbreviates the occasional event RGE. |
| reflujo gástrico | General | NIDDK's Spanish rendering of "acid reflux": it titles its section "Reflujo gástrico (RGE y ERGE) en adultos" and lists the term among the names doctors use, alongside "acidez" and "reflujo". |
| acidez crónica | General | Given by MedlinePlus en español as another name for its gastroesophageal reflux (ERGE) topic. |
| agruras | Mexico | Everyday plural word for heartburn ("acidez estomacal"), the symptom rather than the condition; the singular "agrura" is recorded in Central America, Cuba, the Dominican Republic and parts of the Andes. |
"Reflujo" is a masculine noun, and its medical sense in the Real Academia Española dictionary is the backward flow of a body fluid, with "reflujo gastroesofágico" as the example. MedlinePlus en español uses "reflujo gastroesofágico (RGE)" for the occasional event and "enfermedad por reflujo gastroesofágico (ERGE)" for the chronic condition, and uses "reflujo ácido" when it describes the esophageal pH test.
The abbreviations change between languages: GER becomes RGE and GERD becomes ERGE, so a Spanish-language record that says "ERGE" refers to the disease, not to occasional reflux. "Acidez" and "agruras" name heartburn, the burning symptom, although NIDDK notes that doctors also use "acidez" for reflux itself.
MedlinePlus advises getting medical help right away ("busque atención médica de inmediato") for chest pain with shortness of breath, or pain in the jaw or arm, because these can be signs of a heart problem.
