Menstruation (Menstruation, Menses)

Menstruation (Menses) is the cyclic rejection of the thickened functional layer of the endometrium and the release of blood from the uterus, which occurs monthly in women of childbearing age (see Menarche, Menopause). Menstruation is one of the stages of the menstrual cycle that occurs if fertilization of the egg has not occurred. Typically, the duration of menstruation can range from three to seven days. In the case of anovulatory menstruation (anovular menstruation), menstrual bleeding occurs without the first release of the egg from the ovary. During vicarious menstruation, a woman experiences cyclically occurring bleeding, corresponding to the timing of menstruation, from the mucous membranes of the nose, gums, stomach, and oral cavity, and not from the uterus. During retrograde menstruation, a woman experiences a reverse flow of menstrual blood and endometrial fragments through the fallopian tubes (see Endometriosis). See also Amenorrhea, Dysmenorrhea, Epimenorrhea, Hypomenorrhea, Menorrhagia, Oligomenorrhea.

Menstruation is a natural process that occurs in women of childbearing age. This is a cyclical shedding of the functional layer of the uterus and bleeding that occurs monthly.

Menstruation begins on the first day of the menstrual cycle. During this period, ovulation occurs, which can lead to fertilization of the egg and pregnancy. If fertilization does not occur, then menstruation begins.

The duration of menstruation is usually from three to seven days, but can vary depending on the individual characteristics of the body. During menstruation, a woman may experience some symptoms such as abdominal pain, headaches, nausea and others.

However, not all periods are the same. Some women may experience anovulatory menstruation, which is when menstrual bleeding occurs without the release of an egg from the ovaries. In this case, the menstrual cycle may be disrupted.

In addition, there are other types of menstruation such as vicarious menstruation, retrograde menstruation and endometriosis. Vicarious menstruation can manifest itself in the form of cyclic bleeding from the mucous membranes of other organs, and retrograde menstruation is characterized by the reverse flow of menstrual blood through the fallopian tube.

In general, menstruation is a normal process that helps a woman maintain her health and reproductive function. However, if your period is accompanied by severe pain or other symptoms, you should see a doctor for diagnosis and treatment.

Menstruation (Menses): Physiological process and its features

Menstruation, also known as menstruation or period bleeding, is a natural cyclical process that occurs in women of reproductive age. It is characterized by the rejection of the thickened functional layer of the endometrium - the inner mucous membrane of the uterus, and the subsequent release of blood through the vagina. Menstruation is one of the phases of the menstrual cycle and occurs when fertilization of the egg has not occurred.

Typically, menstruation begins after menarche, the first appearance of menstruation in girls, and continues until menopause, the end of the reproductive period in women. The frequency of menstruation is usually around 28 days, but can vary depending on the individual characteristics of each woman.

The duration of menstruation usually ranges from three to seven days, but can also vary from woman to woman. During menstruation, the uterus contracts, shedding the functional layer of the endometrium, which leads to bleeding. Blood, mucus and endometrial cells leave the body through the vagina as menstrual blood.

Sometimes anovulatory menstruation can occur, where menstrual bleeding occurs without first releasing an egg from the ovary. This can be caused by various factors, including hormonal changes in a woman's body.

There are also rare cases of vicarious menstruation, when bleeding similar to menstruation occurs from the mucous membranes of the nose, gums, stomach, mouth, and not from the uterus. This phenomenon requires additional medical intervention and study.

Retrograde menstruation is a condition in which menstrual blood and endometrial fragments move back through the fallopian tubes into the abdominal cavity. This condition may be associated with endometriosis, a common disease in which endometrial-like tissue grows outside the uterus.

It's important to note that menstruation can be accompanied by a variety of symptoms, including lower abdominal pain (dysmenorrhea), mood changes, fatigue and breast swelling. These symptoms can be individual and vary between women.

In conclusion, menstruation is a natural process in women's lives. It is associated with cyclic rejection and bleeding from the uterus and is part of the menstrual cycle. Menstruation can vary in duration and be accompanied by different symptoms. If you experience unusual or painful symptoms during menstruation, it is recommended to consult a doctor for diagnosis and treatment.
