Women usually start menstruating when they are fifteen or sixteen years old. The monthly menstruation is very painful for girls. There are many taboos after menstruation, such as not drinking cold water, not touching cold water, and not eating spicy food, otherwise the stomach will be very painful. Women's menstruation is also a criterion for testing whether women are healthy. What happens if there are blood streaks and spots on the lips before menstruation? Let’s learn about it with the editor today. Menstruation is a physiological cycle that occurs in some fertile female humans and in chimpanzees and other animals. Cows, horses, camels, pigs, and sheep also menstruate, and some mammals experience estrus cycles. In women of childbearing age and female primates, the endometrium undergoes cyclical changes every month or so, with autonomous thickening, blood vessel proliferation, glandular growth and secretion, and endometrial collapse and shedding accompanied by bleeding. This periodic vaginal discharge or uterine bleeding is called menstruation. The main components of menstruation are blood (3/4 arterial blood, 1/4 venous blood), endometrial tissue fragments and various active enzymes and biological factors. Among them, fibrinolytic enzyme makes menstrual blood liquid and prevents it from coagulating, and prostaglandins play the role of contracting the uterus. Medically speaking, only the reproductive cycle experienced by primates (including humans) is called menstruation. In addition, the reproductive cycle of other mammals is called the estrus cycle. Menstruation is regulated by the reproductive hormone system and is necessary for biological reproduction. A woman's first menstruation is called menarche, and the onset of menarche marks the entry of a woman into puberty. The average age of menarche for girls is 12 years old. Many factors, including genetics, diet, and physical health, can cause menarche to come earlier or later. The cessation of menstruation marks that a woman has entered menopause, also known as menopause. The average age of menopausal women is 51 years old. Of course, just like menarche, many factors such as genetics, disease, surgery and medical treatment can advance or delay menopause. It is normal to enter menopause between the ages of 40 and 58. Menopause occurring before the age of 35 is defined as premature aging. If there are red spots with bloodshot around the lips, you should first rule out the possibility of allergies. Patients are advised to pay attention to timely screening and stay away from allergens, eat light meals and drink plenty of water, try not to eat spicy and stimulating foods, as well as seafood such as fishy shrimps and crabs. Guidance: Go to the hospital in time when necessary, and use anti-allergic and other drug treatments after the doctor's diagnosis, such as chlorpheniramine, vitamin C, and calcium gluconate tablets. |
