What deficiency causes dwarfism?

In fact, dwarfism is mostly not caused by a lack of nutrients, but often by pituitary factors or genetic factors. For example, hypofunction of the anterior pituitary gland and insufficient secretion of growth hormone will affect the growth and development of the body. In addition, if there is a disorder in cartilage development, dwarfism will also occur.

1. Pituitary factors:

It is endocrine dwarfism. Due to congenital (primary) or acquired (secondary) reasons, the anterior pituitary gland function is impaired and growth hormone secretion is insufficient, which hinders the growth and development of the body.

2. Cretinism:

Thyroid hormone is closely related to bone maturation. When the thyroid gland is underactive during childhood, the ossification of cartilage and the growth of teeth are hindered, and the appearance of ossification centers of long bones is significantly delayed, which affects the development and maturation of bone pathways and leads to short stature.

3. Chondrodysplasia:

This disease is caused by the weak growth ability of cartilage and the slow longitudinal development of bones, resulting in severe dwarfism. It is hereditary and not endocrine. The clinical manifestations are: 1) The length of the trunk bones is often normal, but the limbs are obviously short, and the lower body is significantly shorter than the upper body; 2) The spine is lordotic, the abdomen is protruding forward, the buttocks are protruding backward, and the fingers are short and thick; 3) The intellectual development is normal; 4) The sexual organs are normal and the child has reproductive ability.

4. Ovarian hypoplasia:

This disease, also known as Turner syndrome, is a congenital genetic defect in females. The patient has ovarian hypoplasia and dwarfism. Its characteristics are: 1) The closer to puberty, the slower the growth and development; 2) Incomplete development of reproductive organs and primary amenorrhea; 3) Short and fat body with thorax; 4) A significant increase in gonadotropin in the patient's urine, which is the opposite of pituitary dwarfism.
