Why are poor monthly periods after the delay?
Scanty periods after a delay may be because the woman had a low progesterone level in the current cycle. The fact is that progesterone ensures the normal course of the second phase of the cycle, which starts from the moment of ovulation to the onset of menstruation. With progesterone deficiency, there may be a delay in menstruation, since the second phase of the cycle is simply extended. The lengthening of the second phase of the cycle is necessary so that the endometrium of the uterus becomes sufficiently thick and ready to be rejected. If the endometrium does not grow to a normal thickness, then menstruation does not occur, that is, there is a delay.
When progesterone is deficient, the endometrium grows slowly, the second phase of the menstrual cycle becomes longer and there is a delay in menstruation. Progesterone deficiency can occur with various hormonal disruptions triggered by a number of different factors, such as:
- Nervous tension
- Mental injury
- Emotional shock
- Hard physical work
- Improper nutrition
- Changing the familiar environment
- Various endocrine diseases (diabetes mellitus, thyroid pathology, etc.),
- Somatic diseases (pathology of the heart, blood vessels, lungs, nervous system, etc.),
In addition, the delay and subsequent scanty periods can be triggered by postponed catarrhal diseases or inflammatory processes in the organs of the urinary and genital systems of a woman. Very often, a woman freezes, slightly congeals the genital or urinary organs, which leads to a delay, after which there are scanty periods. In such situations, delay and scanty periods are one-time occurrences. During the next cycle, in the absence of negative factors, the monthly normalize and proceed as usual.
Also, a delay with subsequent scanty menstruation occurs during anovulatory cycle. That is, when ovulation was absent in the current menstrual cycle. Such healthy cycles occur in every healthy girl or woman 1 - 2 times a year.
Finally, the cause of poor menstruation after a delay may be pregnancy. In this case, it is not about menstruation, but about a small bleeding that occurs when the embryo is inserted into the wall of the uterus. Many women have such scanty menstrual-like discharge in early pregnancy. This is a variant of the physiological norm.
