The main reason for being short and what are the reasons for being short

Short stature refers to a child's height being less than 2 standard deviations (-2SD) of the average height of children of the same sex, age and race, and the growth rate is less than 5 cm per year. The following conditions suggest that the child has slow growth: the child's growth rate is less than 7 cm years before the age of 3 years; 3 years old to puberty, less than 5 cm years; Puberty is less than 6 cm years.

**。1.Deficiency or insufficient secretion of growth hormone causes the height to not grow normally.

2.Familial short stature.

3.Growth hormone insensitivity or resistance syndrome, mostly caused by mutations in the growth hormone receptor gene, is mostly inherited in an autosomal recessive manner.

4.Congenital ovarian hypoplasia should be identified by karyotyping.

5.About 1 3 intrauterine growth retardation children are short in stature in adulthood.

6.Disorders of bone development: all kinds of bone and cartilage hypoplasia, etc., all have special faces and postures.

7.Growth retardation caused by other endocrine and metabolic diseases: congenital hypothyroidism, congenital adrenal hyperplasia, precocious puberty, hypercortisolism, mucopolysaccharidosis, glycogen storage disease, renal tubular acidosis, etc., each has its own clinical manifestations and is easy to identify.

Certain chronic diseases and malnutrition, etc.

We hope you find it helpful and recommend that you visit the relevant specialist hospital.

The height of the child is greatly affected by genetic factors and environmental factors, parents are tall, the child is naturally tall, and environmental factors are also very important to the growth of the child. Generally speaking, the growth pattern is 50cm at birth, and the first year grows the fastest, and can grow about 25cm taller. During puberty, boys can grow 25-30 cm taller, and girls can grow about 25 cm taller.

Among the environmental factors, a reasonable diet, adequate sleep, appropriate outdoor exercise, and a good mood are all very important for children's growth. Note that the child's annual growth should not be less than 5cm, if the child is much lower than children of the same age, much shorter, you should go to the hospital to check thyroid hormone and growth hormone. If necessary, the epiphyseal line test will be done, and if the epiphyseal line is not closed, the child can still grow up.

What are the causes of short stature? What are the causes of short stature? Let's learn the reasons why everyone is short!

What are the causes of short stature? a.Osteopathic short stature:

Short stature due to bone dysplasia, including chondrodystrophy and cartilage insufficiency. b.Nutritional metabolic disorders short stature:

Individuals suffer from chronic diseases, nutritional disorders, diabetes insipidus, diabetes, etc. c.Short stature with chromosomal disorders:

Chromosomal errors are often accompanied by silly induction, congenital ovarian hypoplasia, etc. d.Endocrine short stature:

This type of disease is mainly caused by too little endocrine hormone secretion, hypothyroidism, precocious puberty, and excessive secretion of adrenal corticosteroids. e. Think that if the parents are tall, the children must be tall: although height is closely related to genetics, heredity only provides a range of personal height, with an error of about 8 centimeters up and down.

Therefore, a child's lifelong height is the result of a combination of genetic and acquired factors. Genetics only selects the growth space of children, but there are many external and acquired factors that affect whether it can be brought into play. As we all know, short stature is a form of short stature in children.

The criteria for judging short stature in children can refer to the following two aspects:1Short stature is diagnosed if the height of patients of the same race, sex, and age in a similar environment is more than 50 or below the 300th percentile of the normal population.

2. The child's height growth can also be used as a criterion. The growth rate of infants and young children under 3 years of age is less than 7 cm-years; 3 years before puberty, growth rate less than 40% years; The growth rate of puberty is less than 30% years, which is considered a slow growth in height. Parents can write down the height of their children during the annual physical examination and draw a line.

If the line flattens or falls, there is a problem. A rough observation is that if the child is less than 7 cm per year until the age of three, less than four to five cm per year through the age of three to puberty, and less than one cm per year during puberty, then a pediatric endocrinologist should be sought as soon as possible for diagnosis and **.
