Dwarfism is defined as a child whose height is less than 2 standard deviations from the average height of children of the same sex, age, and race, and whose growth rate is less than 5 cm per year. Parents should pay more attention to their children’s growth during the development process. Some children may have height growth disorders, such as: dwarfism. So, let’s learn more about the symptoms of dwarfism next.
1, chondrodysplasia: chondrodysplasia is the most common kind of congenital dwarf, a developmental abnormality that belongs to cartilaginous bone defects and normal membranous bone; it is an autosomal dominant hereditary disease, about 80% of cases are sporadic; the physical signs are already obvious at birth, with dwarf being the most significant, typical cases are disproportionate body posture, mainly short limbs, especially the upper arm and femur are the most obvious, while the trunk is still normal; large head The head is large, the face is wide, the forehead and bilateral tops are wide, the middle finger is separated from the fourth finger in a “V” shape, called “trigeminal hand”; the lower limbs are curved, and the intelligence is normal; the final height of adults is 112-136 cm for men and 112-136 cm for women according to statistics. 2. Children’s height growth rate: children’s height can be used as a criterion, the growth rate of infants and children under 3 years old is less than 7 cm / year; 3 years old to pre-pubertal, the growth rate is less than 3-5 cm / year; puberty growth rate is less than 5-6 cm / year, are slow growth in height.
3. Normal body shape, slow growth dwarfism: The child has a uniform short appearance but slow growth, and the most common disease is growth hormone deficiency (GHD). Other diseases include environmental and psychological factors, Turner syndrome caused by chromosomal lesions, and chronic diseases (such as malnutrition, chronic kidney disease, congenital heart disease, chronic asthma, etc.) caused by dwarfism.
4. Disproportionate dwarfism: These children have disproportionate dwarfism in appearance, i.e. the trunk and limbs are disproportionate in length, commonly caused by chondrodysplasia, osteogenesis imperfecta and hypothyroidism. 5. Normal body shape and normal growth rate: These children have proportionate dwarfism in appearance and normal growth rate every year, commonly caused by familial dwarfism.
We hope that parents will pay more attention to their children’s growth, and once they find that their children have unhealthy symptoms, they should go to the hospital for examination and treatment in time so as not to miss the best period of treatment and enable their children to grow up healthy and strong!
