Speaking about the female reproductive system, I would like to note that it is an amazing "mechanism" over which nature has labored fairly. Accordingly, when there is a violation of the menstrual cycle, this is primarily indicative of some kind of failure in the structure inherent in the woman by nature itself. Normally, cyclic changes in the body of each woman occur during every 28 days, they are associated with a fluctuation in the level of hormones, and in this case we consider only those women who are of childbearing age. The result of these changes is considered to be regular bleeding, menstruation, which, in turn, indicates that the female body is being updated, and also signals the absence of pregnancy. Normal is the cycle time, which fits within the framework of 21 to 35 days, accordingly all that goes beyond this norm will be considered for violation of the menstrual cycle. Treatment in this case has the right to appoint only a specialist from medicine, because it consists in taking strong hormonal drugs and in observing a certain regimen.
Considering the causes of violations, it should be noted that they can have a completely different character, depending on the health status of the woman, as well as on what stage of her life she is. The primary cause, which causes a violation of the menstrual cycle, should be considered the presence of the disease. These can be frightening ailments, such as algodismenorea, dysmenorrhea, or oligoamenorea, each of which causes cycle failures for various reasons. However, the most severe in this case is a disease such as amenorrhea, which leads to a lack of menstruation for up to six months.
Speaking about the menstruation cycle, we should not forget about the purely psychological factors that can cause its violation. Too stressful atmosphere, regular outbursts of not always positive emotions and experiences can lead to a serious enough failure even in a very harmonious schedule of menstruation. As a result, menstruation can come with a decent delay, or do not come at all. Sometimes stressful situations provoke too short a cycle, which should also be considered a pathological phenomenon.
Any violation of the menstrual cycle should be a signal for the need to visit a gynecologist, who by examination can detect the presence of any deviations in the health of a woman. Nevertheless, we should not exclude such a factor as too long abstinence from sexual activity, which can also cause changes in the body. Of course, too serious a violation of the menstrual cycle of a woman due to lack of sexual activity is hardly possible, but the delay for several days against abstinence is a fairly common phenomenon and does not require medical intervention.
