FAQs
What affects growth hormone?
The amount of growth hormone in the blood changes during the day and is affected by exercise, sleep, emotional stress, and diet.
Does growth change throughout the day?
Levels of growth hormone vary widely throughout the day, so a single measurement of growth hormone is of limited use. If you are concerned about growth hormone deficiency, we recommend discussing this with your doctor.
What is hGH?
Growth hormone (hGH), or somatotropin, is responsible for normal body growth, metabolism, protein production in muscle cells, and energy release from the breakdown of fats in the body.
