We all know that menstrual cycle, also known as menstrual period or menstrual period, is a period of time that makes every girl extremely "restless". period once a month is about 7 God, how much do you know about "menstrual cycle"? For example, when does a normal menarche begin? How long is a normal menstrual cycle? etc. .
Below is a specific promotion:
1. The age of menarche in women is usually between 13 and 14 years of age, but for some women, time of menarche occurs earlier at 11 years of age (premature menstruation) or later at 16 years of age. Normal (late menstrual cycle);
2. The menstrual cycle specifically refers to physiological cycle of women after puberty;
3. Secondly, female menstrual cycle ranges from 21 to 35 days, but in general it is about 28 days (about a month);
4. Depending on place of origin (eg, ovary, uterus), each menstruation can be divided into several stages. The ovarian phases can be divided into follicular, ovulatory, and luteal phases, while uterine phases can be divided into menstrual, proliferative, and secretory phases, and each phase is closely related to endocrine system.A recent University of Queensland study found that early menstruation is associated with worsening menopausal symptoms.
School of Public Health researchers analyzed data from more than 18,000 middle-aged women in many countries. The results showed that women (girls) who began menstruating at age 11 or younger, decades later, or during menopause, had a 50% increase. may experience more frequent hot flashes and night sweats than usual.
Dr Xin Fangzhong of University of Queensland believes that women who have early periods are more likely to experience these two symptoms than hot flashes or night sweats.
Early menstruation (early menstruation) has previously been associated with certain health conditions, including cardiovascular disease and type 2 diabetes.
Experts analyzed data as part of International Collaboration on Reproductive Health and Chronic Diseases throughout life.
Geeta Mishra, project leader, also believes that not only this one-sided factor, but obesity also played a role in results of study. She hopes study will encourage more people to become aware of need to increase physical activity, thereby highlighting importance of maintaining a healthy weight.
It showed that compared to normal-weight women aged 14 years and older, women with early onset of menstruation who were overweight or obese in middle age were twice as likely to have frequent hot flashes and night sweats as women with a normal menstrual cycle.
Therefore, it is very important to identify and encourage women with early menstruation (premature menstruation) to participate in health promotion programs, especially adult weight control, in order to have a preliminary and general idea of their own health status meaningful!
