Sex, age, nutrition, exercise, trauma and many other factors have an effect on growth hormone secretion. Generally, growth hormone stimulation test is performed to detect the peak growth hormone, less than 5 μg/L is a complete deficiency, and 5 to 10 μg/L is a partial deficiency. Therefore, if the growth hormone 1.6 is the peak value of the test is considered low, if not, it should be analyzed on a case-by-case basis. Under physiological conditions, growth hormone is secreted in a pulsatile manner, which is related to the integrity of the hypothalamus, pituitary gland, neurotransmitters, and the structure and function of the brain, with obvious individual differences, and is affected by factors such as sleep, exercise, intake, and stress, and varies greatly between genders and ages. Due to the low level and rhythmic secretion of growth hormone, a single measurement of blood growth hormone level cannot truly reflect the body’s secretion, and excitation tests are most commonly used to assess its deficiency or not. Generally speaking, a growth hormone peak value of less than 5μg/L is regarded as a complete deficiency, and a peak value of 5-10μg/L is regarded as a partial deficiency. It is recommended to consult your local hospital for details.
