There are many elements which go into the proper functioning of the human body. Cells, tissues, organs, bodily secretions and hormones are some of these components. The chemical messengers which act as messengers to various bodily functions are termed as hormones. Composed of amino acids, these hormones move around throughout the body giving out secretions which aid in carrying about  several functions. These hormones are specific to the kind of response that they are meant to trigger in the human body.  One such hormone is the Human Growth Hormone (HGH) which like other hormones is made up of amino acids which are specific towards this particular hormone.

The Human growth hormone is secreted by the pituitary glands and is involved in roles specific to it which include growth regulation, initiation of cell regeneration and ensuring proper metabolic activities in the human body.
In an ideal case the body continues with the production of the human growth hormone during most of the individuals lifetime though the amount produced sees a significant dip as the individual ages.

The human growth hormone as discussed earlier is responsible for ensuring proper growth of the individual in terms of his height throughout his life. But abnormal doses of the human growth hormone when present in the body has its own share of problems. An increase in the amount of HGH can result in abnormal height which would be far beyond the normal average height seen in an individual while on the other hand a substantial decrease in the human growth hormone in the body will ensure that the individual becomes a dwarf.
Though it is the height aspect which is a major function of the human growth hormone but there are several other activities too in the human body which are regulated by the presence and production of the human growth hormone. The notable functions amongst these include its role in ensuring a younger looking skin, it also helps the body to get rid of excess of cellulite, it aids in keeping our bones strong and healthy and at the same time enhances the energy levels of our body. The other functions include the role of the human growth hormone is its role in the re growth of several organs which shrink considerably over a period of time, to its help in having a stringer immune system. What ever be the role taken up by the human growth hormone the one thing that is clear is that it si very important for the proper functioning of the human body.
