I believe everyone knows what menstruation is. Menstruation is of great significance to female friends. Female friends are prone to various abnormal conditions during menstruation, so we recommend that female friends must pay attention to their food, clothing, housing and transportation during menstruation. Some female friends are prone to symptoms of weak legs during menstruation, so what exactly causes weak legs during menstruation? Menstruation is a physiological cycle that occurs in some fertile female humans and in chimpanzees and other hominins. Cows, mares, female camels, sows, and sheep also have menstruation, 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. 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 women is 12. 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. It is normal to have weak legs during menstruation, because you have to fight pain during menstruation, your mental resistance is obviously reduced, and coupled with a lot of bleeding, your body is weak. Therefore, you should pay attention to supplementing red substances, and avoid cold and spicy foods. In the above article, we introduced the importance of menstruation to female friends. Female friends are prone to some special situations during menstruation, such as the weak legs mentioned above. Through the above analysis, we know that heavy bleeding during menstruation can easily lead to weak legs. |
