So what causes menstrual irregularities? If you don't pay attention to hygiene during menstruation, don't pay attention to keeping warm during menstruation, like to eat cold food, don't pay attention to rest, and body cold will lead to disordered menstruation.
What causes menstrual disorders
Bad living habits such as irregular work and rest, excessive eating, etc. can lead to changes in the endocrine environment, which can easily lead to irregular menstruation in women. In addition, some gynecological diseases, uterine fibroids, endometrial polyps, etc. are also causes of irregular menstruation in women.
1. Irregular work and rest. Due to the influence of life or work, people often stay up late or have reversed work and rest schedules. Such bad work and rest habits can easily lead to endocrine disorders and irregular menstruation.
2. Excessive weight loss. Uncontrolled weight loss or excessive exercise will cause the body to not take in enough protein and fat, which will affect the normal synthesis of estrogen in the body and lead to scant menstruation or amenorrhea.
3. Emotional factors. If you are depressed, anxious or under great mental stress for a long time, the function of the hypothalamus will be damaged, and the ovaries will be unable to secrete hormones and ovulate, which can easily lead to irregular menstruation.
4. Abortion surgery. Multiple abortion surgeries can lead to thin endometrium, uterine damage that is difficult to repair, and even lead to irregular menstruation, amenorrhea, and infertility.
5. Uterine fibroids. Women with uterine fibroids usually experience irregular menstruation, which is mainly characterized by heavy menstrual flow and extremely long menstrual periods. The severity of the symptoms depends on the pathology of the uterine fibroids.
6. Thyroid problems. Hyperthyroidism or hypothyroidism can also affect ovarian function and make menstruation irregular.
7. The impact of the birth control ring. The IUD is a foreign body outside the body and can irritate a woman's endometrium, causing irregular menstruation and amenorrhea.
How to calculate the menstrual cycle
A complete menstrual cycle is calculated from the first day of menstruation to the first day of the next menstrual period. Normally, the menstrual cycle is measured in one month, but in fact it varies from person to person. The calculation of menstrual cycle should include the time of menstrual cramps. Some women only calculate the time when menstruation is clean, so they may think that the menstrual cycle is shortened. A menstrual cycle generally lasts 21-35 days, with an average of 28 days. It is normal to have one period at the beginning and the end of the month.
The menstrual cycle is also called the ovarian cycle and is divided into four phases, including the follicular phase, ovulation phase, luteal phase and menstrual phase:
1. Follicular phase: follicular phase It is from the first day of menstruation to the day of ovulation. During this period, under the influence of follicle-stimulating hormone, the concentration of estrogen hormones in the body increases, the follicles gradually mature, and the endometrium thickens.
2. Ovulation period: Ovulation period refers to the process in which egg cells and surrounding cumulus granulosa cells are expelled together. A woman's ovulation date is generally about 14 days before her next menstrual period.
3. Luteal phase: The luteal phase refers to the period from ovulation to the day before menstruation. The ovaries are affected by lutein-stimulating hormone and secrete progesterone to maintain a thickened endometrium to facilitate the implantation of fertilized eggs. Bed, if no fertilized egg implants, the endometrium will collapse and the menstrual cycle will end with the onset of menstruation.
4. Menstrual period: The duration of each menstrual period is called the menstrual period, usually 2-8 days, with an average of 4-6 days. Generally, there are no special symptoms during menstruation. However, due to pelvic congestion and the effects of prostaglandins during menstruation, some women may experience discomfort in the lower abdomen and lumbosacral region or painful uterine contractions, and may experience symptoms of gastrointestinal disorders such as diarrhea.
