Whereas Somatostatin, an inhibitory hormone that inhibits the release of somatotropin belittles.
Physiologically it will during sleep the most Somatotropin in the pituitary gland educated.

therapy

Growth spurts are commonly biologically preprogrammed and necessary for healthy physical and mental development of children and adolescents.

However, in some cases this not really get lost, either too strong or too weak are pronounced and may be associated with further complications. These may require targeted therapy.

During the pubic growth spurt, the lateral curvature of the Spine (Scoliosis) the strongest. If this phase runs unevenly or particularly quickly, it can lead to a Imbalance come and through Back pain cause. Is the Scoliosis severe pronounced and that growth still not completed, for example physical therapy and wearing one Corsets to be necessary. In very extreme cases may even have to be the spine operational be straightened up.

Also Knock knees and bow legs occur relatively often in young children. Shortly after the start of the run a knock-kneed position is even that Normal findings. This corrects himself usually by itself up to the age of six and does not require any further therapy. However, it shows no spontaneous correction or take the Misalignment even to, should regular check-ups occur.

This is sometimes necessary when a very large body is expected and the growth spurts are so rapid that they cause additional discomfort. For example, you can thereby create a Prevent scoliosis or their Reduce expressionwhich otherwise often causes lifelong back problems for those affected.

An excess of growth hormones is also with one Pituitary gland tumor conceivable. Both short and tall stature can also hereditary be conditional and must therefore be precise in each individual case to be clarified. The drug therapy is actually an intervention in the Hormonal balance and should therefore only go through doctor's prescription and carried out under strict control.
