hyperchlorhydria
Extremely Low / SpecialistTechnical/Medical
Definition
Meaning
The excessive secretion of hydrochloric acid by the stomach.
A medical condition characterised by abnormally high gastric acid levels, often associated with symptoms like heartburn or indigestion, and sometimes linked to peptic ulcers or Zollinger-Ellison syndrome.
Linguistics
Semantic Notes
A highly specific clinical term. Used almost exclusively in gastroenterology. Its opposite is 'hypochlorhydria' (low acid) or 'achlorhydria' (no acid).
Dialectal Variation
British vs American Usage
Differences
No significant spelling or usage differences. The condition is defined identically in both medical communities.
Connotations
Purely clinical, with no regional connotative variation.
Frequency
Equally rare and specialist in both varieties.

Examples
By Part of Speech
adjective
British English
- The hyperchlorhydric state was confirmed by gastric analysis.
American English
- A hyperchlorhydric patient may require proton-pump inhibitors.
Examples
By CEFR Level
- Some stomach pains can be caused by hyperchlorhydria, which means the stomach makes too much acid.
- The endoscopy was clear, but persistent symptoms led to a gastric pH study, which revealed idiopathic hyperchlorhydria.
Learning
Memory Aids
Mnemonic
HYPER (over) + CHLOR (like chlorine, part of hydrochloric acid) + HYDR (water, but here relates to acid) + IA (condition). Think: 'HYPER-active CHLORine-HYDRogen-IA condition' for overactive stomach acid.
Conceptual Metaphor
STOMACH IS A CHEMICAL FACTORY (producing an excessive/dangerous amount of a key chemical).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct calque 'гиперхлоргидрия' exists and is correct, but a doctor might more commonly use the descriptive phrase 'повышенная кислотность желудка' (increased stomach acidity).
Common Mistakes
- Misspelling: 'hyperchlorhydia' (missing 'r'), 'hyperchlorhydrea' (incorrect ending).
- Confusing it with 'hyperchloremia' (high blood chloride).

FAQ
Frequently Asked Questions
No. Hyperchlorhydria is the condition of having too much stomach acid. Acid reflux (GERD) is one possible consequence, where that excess acid flows back into the oesophagus.
While stress can exacerbate acid production and symptoms, true idiopathic or pathological hyperchlorhydria usually has an underlying medical cause, such as a gastrin-secreting tumour.
Treatment typically involves acid-reducing medications like proton-pump inhibitors (e.g., omeprazole) and H2-receptor antagonists, alongside investigation and management of any underlying cause.
No, it is relatively rare. Simple indigestion or heartburn is much more common and often does not involve truly excessive acid levels, just sensitivity or reflux.
