Why do I have hip pain during my period?

Buttock pain in women during menstruation is a normal physiological condition and is generally attributed to premenstrual syndrome. Because after entering the menstrual period, there is a lot of shedding of the uterine wall and the bleeding is relatively heavy. In addition, the female hormones in the body will undergo significant changes, and the body's metabolic rate will also undergo significant changes, making it easy for lactic acid bacteria to form in the body.

Menstruation is a physiological cyclical period that occurs in some reproductive female humans, apes, and other animals. Cows, horses, female camels, pigs, and sheep also have periods, and some mammals experience estrus cycles in person. In mating and breeding female primates, every month or so, the uterine wall undergoes independent thickening, blood vessel proliferation, glandular duct metabolism, and the uterine wall collapses and falls off with the regular changes of bleeding. This regular vaginal discharge or uterine bleeding is called menstruation. The blood discharged during menstruation is also called menstruation.

The female reproductive organs are composed of the uterus, ovaries, uterus, bilateral fallopian tubes, and vagina. The main function of the ovaries is to produce eggs and produce ovarian hormones. The uterus and fallopian tubes are reproductive organs. There are tens of thousands of eggs in the ovaries, and each egg contains one egg cell.

Before puberty, the egg is essentially useless. During puberty, under the action of gonadotropin from the anterior pituitary gland, the imperfect egg gradually grows and produces estrogen. When the uterus is fully developed and ovulation occurs, the egg wall collapses, the cells enlarge and turn yellow, which is called progesterone. It produces estrogen while producing estrogen.

As the uterus and ovaries change, the uterine wall also undergoes relatively regular changes. Estrogen causes the endometrium to thicken, the endometrial cells to increase and expand, and the intrauterine arteries to become more tortuous and spiral, which is called the reproductive uterine wall. During the ovulation period, due to the interaction of estrogen and oestrogen, the uterine wall swells, the glandular ducts produce a large amount of mucus and glycogen, and the thickness of the endometrium increases from 1mm to 6mm, which is called the metabolic period of the uterine wall.

If the egg is not fertilized, about 14 days after ovulation, the corpus luteum shrinks and stops secreting estrogen and estradiol. At this time, the blood vessels in the uterine wall contract, the endometrium necrotizes and falls off, causing bleeding and menstruation.

Therefore, the length of the menstrual cycle depends on the length of the uterine and ovarian cycle, which is generally 21-30 days, but varies from person to person, and may be 23-45 days, or even three months or half a year as a cycle. As long as there is regularity, it is generally considered a normal menstrual period.

The bleeding time is generally 2-7 days, and the total amount of bleeding during each menstrual period is 30-50ml. Many people think that menstrual volume greater than 80ml is a pathological condition.
