A woman’s life is divided into seven different physiological stages, each with its own characteristics, so the focus is also different. Understanding the physiological characteristics of women allows every step of growth to go smoothly. Prevention is the best cure, and prevention is the secret to a lifetime of health benefits for women. The ancients said it well: the top doctor treats the untreated disease, the middle doctor treats the future disease, and the bottom doctor treats the existing disease. Here are a few important stages for women. I. Childhood From birth 4 weeks to about 12 years old. 1, to prevent the occurrence of precocious puberty: pay attention to diet, eat breakfast on time, eat less dinner, slow down meals, do not eat or eat less high-calorie, fried and puffed food, not picky eaters, control weight, exercise.

Once you notice the emergence of pubic hair and breast development, you should consult a doctor as soon as possible to prevent premature development from leading to a short adult size, which may affect your work and life in the future. 2. Pay attention to hygiene. Wash your vulva every day, change your shorts regularly, and wash your shorts separately. Use paper to wipe after a bowel movement, from front to back.

Adolescence is a period of transition from childhood to adulthood, where physical changes affect psychological and personality changes, so special attention should be paid. The onset of puberty begins at the age of 8 to 10 and is related to genetics, living environment, nutritional status and psycho-spiritual factors. 1. The first female sex characteristics: As the ovaries enlarge and follicles develop, they secrete two major female hormones: estrogen and progesterone. Estrogen is the hormone that makes a woman feminine, and progesterone is the hormone that protects a woman, one without the other. The internal and external genitalia begin to develop, the mons pubis bulges, the labia majora and minora are thickened with pigmentation, the vagina becomes wider and longer, the uterus increases in size, etc. 2.

Third, sexual maturity, also known as the reproductive period, usually starts at the age of 18 and lasts for about 30 years. Regular menstruation is established and fertility function is available. Attention should be paid to the prevention of gynecological diseases, including gynecological inflammation, gynecological tumors and gynecological endocrine disorders. Annual pelvic ultrasound is recommended, and those who are sexually active must also undergo annual gynecological examinations and regular cervical screening. An important task during this period is childbirth, including preparation for pregnancy, pregnancy checkup and postpartum recovery. 1. Before preparing for pregnancy, you should go to the hospital for checkups, ultrasound to see if the uterine adnexa are normal and to rule out any lumps; gynecological checkups to see vulvar development, vaginal patency, and cervical polyps, etc. Cervical cancer screening (TCT and/or HPV) is done to rule out cancer and precancerous lesions.

The earliest can start at the age of 40, mostly 45 years old, lasting as short as 1 to 2 years, as long as 10 to 20 years. Menstruation is irregular due to the gradual decline of ovarian function. If menstruation is heavy or lasts for a long time, you must pay attention to gynecological tumors and abnormal uterine bleeding and seek medical attention as soon as possible. The permanent termination of menstruation is called menopause, and the average age of menopause for women in China is 49.3 years old, depending mainly on heredity.
