Childhood and adolescence of "catch-up growth"

It found that many children suffering from anorexia nervosa, low thyroid function, intestinal malabsorption and malnutrition diseases such as SARS, will hinder the normal development. But after impede effective treatment, if it is to overcome, the children will be to speed the resumption of growth. At this stage of rehabilitation to speed up the growth of the phenomenon, known as the "catch-up growth." Characterized by the growth of the duration of the normal length of children, development of the situation to improve significantly more. As a result, children in a variety of prevention and treatment of acute and chronic diseases and consumption of diseases, to ensure their normal development is very important. For example, some of hypothyroidism in children 8 to 10 years old when the growth rate of less than half of normal children, bone development has clearly failed, the small bone age. The use of hormone therapy after the film, appeared to catch up with rapid growth. Six months later, the growth rate of up to the local children of the same age and average speed of 2-4 times the rate of bone age to catch up with the growth of up to 3 times the average. It is precisely because of the growth to catch up with these children despite the sudden increase in the beginning of full age and maturity are deferred for two years or so, but can also reach the normal level of height.

However, not all diseases are bound to resume the process of "catch-up growth", children can "catch-up growth", so that growth can return to the normal track of the original, depending on the cause of the disease, the duration of the disease And the extent of the problem. If the lesion involving the central nervous system and a number of important endocrine gland, a serious disease, or metabolism in the body can not balance the long-term recovery, will not be able to "catch-up growth." Furthermore, the same disease can be treated as a result of timely and different. In general, early symptomatic treatment is very important. The younger, to achieve a high level of "catch-up growth," the greater the possibility.

In addition, children suffering from different diseases have different "catch-up growth" performance. For example, idiopathic pituitary growth hormone deficiency in children, although the use of growth hormone therapy for many years, but his adult height of children in general are still lower than normal. The reason is that children with such speed and height growth rate of skeletal maturation is not exactly the same. Useless in the growth hormone, even though growth is stopped, the bone is still slow maturation process carried out. By the use of growth hormone therapy, is greatly accelerate the pace of growth, but because of the growth plate closure of the restrictions, is the "catch-up growth," the potential is often not fully developed. This situation will be referred to as "incomplete to catch up with growth." And we give in front of the children with hypothyroidism example, as the children's height and bone age is parallel to the backward, behind the bone age and sometimes even more evident. In the provision of hormone therapy, is to catch up with the growth rate higher than that of bone age, the recovery period for the "catch-up growth," the fight for more time to provide a greater potential. This situation will be referred to as the "complete catch-up growth."
