1, too harmful:
Excessive growth hormone mainly causes excessive growth of bones, soft tissues and internal organs, which is manifested as gigantism in adolescents and acromegaly in adults.
Skull thickening, wide head and face, high cheekbones, prominent mandible, sparse teeth, poor occlusion, thick hands and feet, hunchback, rough skin, increased hair, pigmentation, hypertrophy of nose, lips and tongue, hypertrophy of vocal cords, and bass may appear.
2, the harm is too small:
Insufficient secretion of growth hormone leads to physical retardation, which leads to dwarfism and dwarfism.
Its growth is slow, there is no puberty, and it has the appearance of "old children" premature aging in adulthood; The body is short, but the trunk, limbs and head are symmetrical; Epiphyseal development is slow, and the bone age is lower than its actual age; Symptoms such as hypoplasia of sexual organs and hypoplasia of secondary sexual characteristics.
Extended data:
Growth hormone is very important for children's growth and development, and it is secreted most during sleep.
"The length of children's sleep time and the length of sleep time are very important. Whether they are reasonable has become an important factor affecting their height. " Director Ye Jin explained that growth hormone is the main driving force for children to grow taller, and only when the growth hormone is secreted sufficiently can they grow taller and shorter.
The level of growth hormone at night is much higher than during the day, especially at the peak of children's growth, and nearly 90% of growth hormone is released at night. So it's important to have a good sleep at night. Missing it will affect growth.
Sleep time is very important. The secretion of growth hormone at night is unbalanced, with more at night in the second half of the first half of the year, and the two peak periods of growth hormone secretion are at night and at 5: 00-7: 00 in the morning, accounting for about 90% of the secretion of growth hormone at night, with a little peak at 6: 00 in the morning.
