The 8 main reasons why children are short are always a concern for parents, and there are indeed many babies who are short in life, and the reasons for this are the following.
The causes of short: 1, genetic influence: because of genetic genes caused by the short is called “familial short”. These short children show a normal growth rate, the growth curve is parallel to the curve of normal children, but always at the low limit, in kindergarten or elementary school class height queue, often in the forefront. They are physically healthy, have normal intelligence and normal laboratory tests. These children have puberty on time and are short in height in adulthood.
2. Delayed puberty development: Short stature in childhood is due to the late onset of puberty and sexual maturity, and normal height by adulthood. These children have normal height at birth. After 6 months to 2 years of age after birth, their growth rate is slower than that of children of the same age. After 3 years of age, their growth rate is normal, their growth curve is parallel to that of normal children, and their epiphyses close 2 to 3 years later, thus they have normal growth potential. But before puberty they look short compared with children of the same age, and puberty height surge, the age of boys after 16 years old, girls after 14 years old, and finally adult height is normal.
3, small size at birth: full-term born children weighing less than 2.5 kg is called full-term small-like children. There are also premature small-like children. These small children in the mother’s womb developmental delay. There are various reasons: such as the mother’s nutritional deficiencies, severe pregnancy reaction vomiting, eating very little; there are placental and umbilical cord factors and maternal disease during pregnancy.
4. Mental depression: Emotional deprivation dwarfism such as children caused by discrimination and abuse, once the environment is changed they will grow normally again.
5. Growth hormone deficiency: caused by insufficient secretion of growth hormone by the pituitary gland or structural abnormalities. The vast majority of the causes are unknown, and about 2/3 of the affected children have a history of breech delivery. The children are particularly short and start to grow very slowly at the age of 1 to 2 years after birth, growing only 1 to 3 cm per year, with an average adult height of 137 cm. dwarfism is proportional, i.e. the limbs, head and trunk are proportionally short, and the bone age is significantly behind the actual age. Intelligence is normal.
6. Hypothyroidism: caused by insufficient secretion of thyroid hormones. The majority of congenital j hypothyroidism is caused by congenital underdevelopment or underdevelopment of the thyroid gland. During the neonatal period, it may manifest as much sleep, little crying, little movement, long jaundice, cold limbs, low body temperature, constipation, abdominal distension, feeding difficulties, etc. Later, it may manifest as slow growth and mental retardation.
7, congenital ovarian hypoplasia: occurs in girls, due to sex chromosome abnormalities. There are many manifestations of this disease, but almost all patients have short stature and slow growth, and most adults are about 140cm tall.
8. Systemic diseases that cause short stature: chronic malnutrition, chronic diarrhea, congenital heart disease, respiratory disease, anemia, kidney disease, infection, etc. can cause growth disorders in children.
Prevention of childhood dwarfism: Children’s height is the result of the interaction between heredity and environment. Parents should create a good environment so that the growth potential of children can be fully developed and children can grow as tall as possible.
1. If improper feeding or disease after birth can lead to short stature. Therefore, it is important to have adequate nutrition throughout the infant and toddler period, add supplementary food in time and prevent diseases. For the birth of small samples of children more to enhance nutrition and care, so that they accelerate growth.
2, we should pay attention to reasonable nutrition, do not be partial food, less snacks, 1 to 2 hours before the meal it is best not to eat candy or drink drinks, which is conducive to good appetite. Exercise often, because the secretion of growth hormone increases after exercise, which is beneficial to growth. The secretion of growth hormone in normal people is pulsatile and mainly occurs at night during sleep, so adequate sleep is also important for growth.
