Normally the duration of periods ranges from 3 to 6 days. This is when the exfoliated endometrial lining, which had been preparing for possible conception in the previous cycle, is discharged through the vagina. In the case, if the period only lasted 2 days, it is appropriate to speak about hypomenorrhea. Physiologically, having a short period is considered normal during hormonal alterations in the organism and intake of hormonal contraceptives. There are 2 congenial and 7 acquired causes or pathological scantiness of periods.
In fact, periods are nothing but monthly discharge of blood and elements of endometrium, exfoliated due to alteration of hormonal profile. Menstruation appears to be one of the components of regeneration in the reproductive system. As a rule, the volume of blood loss does not exceed 35-50ml, and periods last from 3 to 6 days. Decrease of the amount of blood or obvious reduction of periods is commonly referred to as hypomenorrhea.
When is a short period considered normal?
Two periods (apart from pregnancy) can be outlined in the life of a woman, during which major hormonal alterations takes place. One of these periods is the year, following menarche (the first period) and 3-4 years before menopause (a critical period of time, which is characterized by complete absence of menstruations in 12 months). The last mentioned period is called perimenopause.
Scantiness and reduced duration of menstruation are considered to be physiologic in these two periods. Anovulatory cycles can be observed, which has to do with the fact that in these new conditions, the organism does not provide for sufficient secretion of hormones. Besides, endometrial lining, which does not fully prepare itself to possible impregnation, simply does not accumulate enough content to provide for normal periods.
It should also be noted that the condition when period only lasts a day or two is normal in women, who take hormonal contraceptives. Such drugs deliberately provoke cycles, in which the ovum does not maturate and fails to emerge from the follicle, which contributes to the minimization of periods.
What can permanently short periods mean?
For a certain group of women 1 or 2 day period is a permanent practice. This may be the case with a congenial pathology of the genital tract, which is first of all presented by inadequate development of secondary sexual characteristics (underdeveloped breasts, hair growth problems, etc.) and infertility.
Thorough examination can reveal development disorders in internal genitalia – uterus and ovaries. Conditions, which are accompanied by short periods include:
- Triple X syndrome – the genetic disorder, associated with chronic anovulation;
- Asherman syndrome – inherent synechias (adhesions) in the uterine cavity, which do not allow for normal growth and monthly transformation of the endometrial lining.
