The length of menstrual cycle varies from person to person, ranging from 20 to 40 days is normal, and each woman's menstrual date has its own regularity. So what are the reasons for the longer menstrual cycle? The following is my introduction to the reasons for your longer menstrual cycle. I hope it can help you.
1. Abnormal central nervous system hypothalamus
Including mental stress, such as reactions caused by mental stress such as environmental change, excessive tension and mental strike; There are also dysregulation or inhibition of hypothalamic gonadotropin secretion caused by weight loss, anorexia nervosa, excessive exercise and drugs; In addition, there are congenital diseases or brain malformations and tumors that cause abnormal hormone secretion.
2. Uterine abnormalities
Uterine dysplasia and endometrial destruction can also cause sparse menstruation and even amenorrhea. Endometrial destruction includes inflammatory factors, such as endometrial tuberculosis; It can also occur in endometrial basal layer injury or adhesion caused by excessive curettage after postpartum or induced abortion.
3. Ovarian abnormalities
Abnormal menstruation caused by congenital ovarian dysplasia or abnormal ovarian function or secondary lesions, such as polycystic ovary syndrome, with clinical manifestations of sparse menstruation, irregular, hairy, obesity and so on; Ovarian functional cyst; Ovarian tumors affect menstruation due to hormone changes. Then there is a serious pelvic infection, which can also damage the bilateral ovarian tissue, thereby affecting menstruation, and even permanent amenorrhea. Tuberculosis is more common.
4. Pituitary abnormalities
It refers to the abnormal secretion of gonadotropin caused by pituitary lesions, including congenital factors and acquired lesions, such as pituitary tumors.
The reasons for the longer menstrual cycle are multifaceted and complex, including genetic problems, endocrine problems and immune problems, as well as rare menstruation caused by psychoneurological factors, tumors, trauma and drugs. If such problems occur for a long time, it is best to go to the hospital for relevant examination, identify the possible causes and try to carry out targeted treatment, otherwise it may affect fertility for a long time.
1. Follicular period: the follicular period 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 hormone 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 discharged together. Women's ovulation date is generally about 14 days before the next menstruation.
3. Luteal phase: luteal phase refers to the period from ovulation to the day before menstruation. Under the influence of luteal stimulating hormone, the ovary secretes luteal hormone to maintain the thickened endometrium, so as to facilitate the implantation of fertilized eggs. If there is no implantation of fertilized eggs, the endometrium will disintegrate, and the menstrual cycle will end with menstruation.
4. Menstrual period: the duration of each menstruation is called menstrual period, which is generally 2-8 days, with an average of 4-6 days. Generally, there are no special symptoms during the menstrual period, but during the menstrual period, due to pelvic congestion and the role of prostaglandins, some women will have discomfort of lower abdomen and lumbosacral falling or uterine contraction pain, and may have gastrointestinal dysfunction symptoms such as diarrhea. A few women may have headaches and mild neurological instability.
Why is my menstruation never allowed? Is there a problem? I believe this is one of the difficult problems for women. Women really have no choice about the good friend "big aunt". They worry about coming early, worry about coming late, worry about coming too long, and panic about coming too short. How many days is the menstrual cycle normal? Details are as follows:
The female menstrual cycle begins with the first day of menstruation and ends with the next menstruation. The length of the cycle varies from person to person, ranging from 21 to 36 days, with an average of about 28 days. The duration of menstruation is generally 3-7 days, with an average of 5 days. The menstrual cycle is separated by the day of ovulation, which is divided into the follicular phase before ovulation and the luteal phase after ovulation. The length of follicular phase is not certain, but the luteal phase is fixed for about 14 days.
Within this range is the normal menstrual cycle.
