favism
LowTechnical/Medical
Definition
Meaning
A hereditary condition causing acute hemolytic anemia following consumption of fava beans or exposure to their pollen, due to a deficiency of the enzyme glucose-6-phosphate dehydrogenase (G6PD).
The condition can serve as a model for understanding drug-induced hemolytic anemias and genetic susceptibilities to environmental triggers.
Linguistics
Semantic Notes
The term is almost exclusively used in medical genetics, hematology, and clinical contexts. It names both the genetic predisposition and the acute clinical episode triggered by the beans.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage. Spelling is consistent.
Connotations
Purely clinical and genetic.
Frequency
Equally rare in both varieties, confined to specialist literature.

Examples
By CEFR Level
- Favism is a serious illness.
- Some people cannot eat fava beans.
- The patient was diagnosed with favism after eating a fava bean stew.
- Favism is more common in males because it is linked to the X chromosome.
- Genetic counselling is recommended for families with a history of favism to assess carrier status.
- The biochemical basis of favism lies in the inability of red blood cells to manage oxidative stress induced by compounds in the beans.
Learning
Memory Aids
Mnemonic
FAVA beans cause an ISM (condition) – Favism.
Conceptual Metaphor
A genetic lock that is opened by a specific environmental key (the fava bean).

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with "фавизм" (a direct transliteration, correct but rare). The concept is known but the English term is used internationally in medicine.
Common Mistakes
- Misspelling as 'favaism' (though understandable, standard is 'favism').
- Using it as a general term for any food allergy.

FAQ
Frequently Asked Questions
No, it is not an IgE-mediated allergy. It is an inherited metabolic disorder (an enzymopathy) where red blood cells are destroyed due to an oxidative crisis.
No, you are born with the genetic mutation. However, the first acute hemolytic episode is typically triggered in childhood upon first significant exposure to fava beans.
No, inhalation of fava bean pollen can also trigger the reaction in susceptible individuals.
There is no cure for the underlying enzyme deficiency. Management involves strict avoidance of triggers (fava beans, certain drugs like primaquine) and prompt treatment of hemolytic crises.
