Dwarfism vs. Cretinism: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on February 6, 2024
Dwarfism is a condition resulting in short stature, often due to genetic factors. Cretinism is a disorder caused by thyroid hormone deficiency, leading to physical and mental development issues.

Key Differences

Dwarfism is primarily characterized by short stature, typically resulting from genetic mutations affecting bone growth. Cretinism, on the other hand, is a congenital condition caused by a deficiency in thyroid hormones, impacting physical and cognitive development.
Individuals with dwarfism often have proportionate body structures, although some forms can lead to disproportionate limb-to-body ratios. In cretinism, the lack of thyroid hormones can result in developmental delays, stunted growth, and intellectual disabilities.
Dwarfism can be diagnosed through genetic testing and observation of growth patterns. Cretinism, also known as congenital hypothyroidism, is typically identified through newborn screening tests.
Treatment for dwarfism focuses on managing symptoms and complications; there's no cure for the underlying genetic causes. Cretinism requires early and ongoing treatment with thyroid hormone replacement to prevent severe developmental issues.
Social and emotional support is crucial for individuals with dwarfism, as they may face unique challenges in daily life. Early intervention and support are also critical for children with cretinism to achieve the best possible developmental outcomes.

Dwarfism and Cretinism Definitions


Requires adaptations in daily living due to stature.
Schools often make accommodations for students with dwarfism.


Typically detected through newborn thyroid screening.
Early detection of cretinism is crucial for treatment.


Characterized by an adult height under 4 feet 10 inches.
She was diagnosed with dwarfism at an early age.


Can result in stunted growth and cognitive impairment.
Untreated cretinism often leads to lifelong intellectual disabilities.


A medical condition resulting in significantly short stature.
Despite his dwarfism, he excels in various sports.


Requires lifelong thyroid hormone replacement therapy.
She manages her cretinism with regular medication.


Often genetic, leading to reduced growth of bones.
Dwarfism in her family is due to a rare genetic mutation.


A condition caused by severe thyroid hormone deficiency.
Cretinism can lead to significant developmental delays if untreated.


Can be proportionate or disproportionate in body structure.
His type of dwarfism results in proportionate limbs and torso.


Associated with both physical and mental developmental issues.
Children with cretinism need early and ongoing support for optimal development.


The medical condition of being a dwarf.


A congenital condition caused by a deficiency of thyroid hormone during prenatal development and characterized by small stature, intellectual disability, dystrophy of the bones, and a low basal metabolism.


The condition of being a dwarf animal or plant. In both senses also called nanism.


(disease) A condition of severely stunted physical and mental growth due to the untreated congenital deficiency of thyroid hormones.


The condition of being a dwarf person of short stature.


A condition of endemic or inherited idiocy, accompanied by physical degeneracy and deformity (usually with goiter), frequent in certain mountain valleys, esp. of the Alps.


The quality of being puny or inferior.


Severe hypothyroidism resulting in physical and mental stunting


A genetic abnormality resulting in short stature


How is cretinism treated?

Cretinism is treated with thyroid hormone replacement therapy.

What causes dwarfism?

Dwarfism is usually caused by genetic mutations affecting bone growth.
