This kind of situation has continued many years. Her physical growth and the healthy situation are alright, ask that this can be one morbid state?

??One of feminine reproductive system’s physiological characteristics is the periodic variation, the menstruation is this periodic change important symbol. Menstrual cycle’s adjustment mainly through the hypothalamus - pituitary gland - ovary axis, this axis receives central nervous system’s control. Moreover, the menstrual cycle also receives other many kinds of factors the influence, like energetic factor, nutrition condition and environmental variation, and so on.
??Many people have heard, the tropics area’s girl is precocious, displays in the precocity and the menstrual onset; Also some material called individual south girl, when hometown the menstruation is normal, but after actually does not come month after next to the north, but south returns after to restore month after next normally. These explained that the menstrual cycle receives the outside climatic shift the influence, your younger female cousin’s situation probably is also this.
??The above all sorts of situations also can only show that at best certain girls’ menstrual cycles are sensitive to the outside climatic change, cannot be called the morbid state.
