长话短说，这种情况是天生的，后长，成年后正常身高。如果是这种情况（这要由医生确定），中医一定管用， 因为无论吃什么，扎什么，灸什么，小孩一般最后都会长到正常身高。如果这不是中医的疗效，那就没天理了。
只是，不要给小孩种下中药肾病和肝病的根子。按双极大侠的办法吃点狗肉白面之类的应该无妨。

Constitutional delay of growth and puberty — Constitutional delay of growth and puberty (CDGP, sometimes called constitutional short stature for prepubertal children) results in childhood short stature but relatively normal adult height. Children with CDGP are usually of normal size at birth. However, a downward shift in growth rate begins at three to six months of age that is parallel to that seen in most normally growing children in this age group, but tends to be more severe and prolonged. By three or four years of age, children with CDGP usually are growing at a low-normal rate (eg, about 4 to 5 cm/year in preadolescent girls, and 3.5 to 4.5 cm/year in preadolescent boys). The result is a growth curve that remains below, but parallel to, the third percentile for height. In addition to a low preadolescent height velocity, they tend to have delayed pubertal development. This leads to a marked height discrepancy during the early teenage years compared with their peers, but is followed by catch-up growth when they do enter puberty (figure 2).
The hallmark of CDGP is delayed skeletal age; it is more closely related to the height age (age at which one's height would be average) than the chronologic age (table 1). For these children and adolescents, height data should be interpreted according to bone age rather than chronological age to accurately reflect height potential. Because the bone age is delayed, growth typically continues longer than normal, often resulting in adult stature within the normal range. In many cases, there is a family history of delayed growth and puberty in one or both parents (sometimes described as being a "late bloomer").
Differential features of familial short stature and constitutional delay of growth and puberty
| Feature | Familial short stature | Constitutional delay |
| Parents' stature | Small (one or both) | Average |
| Parents' puberty | Usual timing | Often delayed |
| Birth length | Normal or low-normal | Normal |
| Growth (zero to two years) | Normal | Slow from mid-infancy to mid-childhood |
| Growth (two years to puberty) | Normal | Slow |
| Bone age | Normal | Delayed |
| Timing of puberty | Normal | Delayed |
| Pubertal growth | Rate low-normal | Growth spurt delayed; rate slightly diminished |
| Adult height | Short | Normal |
