The textbook female cycle is 28 days. Unfortunately, we are not machines controlled by a quartz watch. The classic menstrual period is not always every four weeks, but subject to multiple influences. Stress, weight problems, climate change, hormonal fluctuation and pregnancy, as well as taking hormonal and non-hormonal preparations (e.g. psychotropic drugs) – all affect the menstrual cycle.
Short-term fluctuations should have no significance, but if mid-cycle bleeding, spotting, fluctuations in cycle duration or the like occur in several cycles in a row, a gynecologist should be consulted to ascertain the cause. In particular, long-term absence of menstruation in young women requires treatment, otherwise deficiency symptoms could arise due to lack of estrogen (e.g. osteoporosis).
In addition, excessive bleeding, which may be caused by polyps, fibroids, hormone imbalances etc., requires short-term investigation, otherwise anemia may occur and ultimately serious conditions need excluding as the cause for such irregularities.
As your gynecologist we can offer you reliable clarification of the cause by examination of the female genital organs, hormone determination in the blood, ultrasound and other diagnostics, thereafter commencing appropriate treatment for you.
