The timing of the onset of puberty in women is influenced by genetic and environmental factors, and the timing of the onset of development varies. If all genetic factors and environmental conditions are normal, women usually start to develop at the age of 9-12. At this time, the rate of development of the uterus and ovaries gradually increases, and the secretion of estrogen in the body increases, prompting the secondary sexual characteristics of women to develop and mature. The human pituitary gland secretes growth hormone, which has a significant effect on the development of bones, bone mass, brain, nerves and intelligence of women. If some women are influenced by genetic factors and environmental conditions, they only start to develop between the ages of 13 and 23, but this is also a normal phenomenon and no clinical symptoms are required for treatment. In addition, during puberty, women’s height grows rapidly and the demand for nutrients in the gastrointestinal tract and other vital organs increases, so it is important to pay attention to supplemental nutrition and to ensure adequate, high-quality sleep.
