What does cretinism mean?
Cretinism is a noun denoting a congenital condition characterised by markedly stunted physical and mental development caused by insufficient thyroid hormone, typically arising before or shortly after birth. Historically observed at high rates in iodine-deficient regions such as the Alps, it is now rare where newborn screening and iodised salt are standard, and modern medicine prefers the term congenital hypothyroidism. The word derives from the French crétin, possibly linked to chrétien, meaning "Christian," reflecting an old Alpine notion that affected individuals retained childlike innocence. Because its related forms, particularly cretin, have become insults, the vocabulary surrounding this word carries significant negative connotation and should be handled sensitively. Cretinism survives chiefly in historical, epidemiological, and public-health writing about iodine deficiency.
nounA condition of severely stunted physical and intellectual growth caused by a deficiency of thyroid hormone, especially congenital hypothyroidism present from birth. The term is now considered dated and offensive, having been replaced in medical use by "congenital hypothyroidism."
- A congenital condition marked by stunted physical growth and intellectual disability resulting from thyroid hormone deficiency, now medically termed congenital hypothyroidism.
"The introduction of routine newborn screening has made cretinism, once common in iodine-deficient regions, largely preventable."
"Iodine supplementation programmes have dramatically reduced rates of endemic cretinism worldwide."
"Historical accounts from remote alpine valleys describe cases of cretinism attributed to iodine-poor soil and water."
Rarely pluralised, since the term usually refers to the general condition rather than individual instances; plural form appears only in older medical literature discussing distinct varieties or cases.
"Nineteenth-century physicians distinguished several regional varieties of cretinisms in their case reports."
The word comes from French crétin, thought to be from chrétien, meaning "Christian" — an old Alpine term implying that people with this condition were nonetheless innocent souls.

Etymology of cretinism
Cretinism derives from the French word crétin, which appeared in Alpine dialects to describe people affected by congenital iodine deficiency; one widely accepted account traces crétin to chrétien, meaning "Christian," suggesting the sufferers were viewed as innocent souls. The English term entered usage in the nineteenth century as physicians documented the condition across Europe. It belongs to the same family as the adjective cretinous and the noun cretin.

How cretinism is actually used
Cretinism is a technical historical medical term; modern clinical practice uses "congenital hypothyroidism" instead. Related words such as "cretin" are widely regarded as offensive when applied to people, either medically or as insults, so writers should exercise care.

"Cretin" refers to the person affected by the condition (and is now used as an insult), while "cretinism" refers to the condition itself.
"Myxedema" denotes severe adult-onset hypothyroidism with swelling of the skin and tissues, whereas "cretinism" refers to hypothyroidism beginning in infancy or before birth.
