Menopause Irregular Periods

One of the earliest signs that a woman is entering perimenopause is irregularity in what was previously a fairly regular menstrual periods. As one approaches menopause, spotting between periods and skipping periods signal weakening hormone signals and herald significant changes to come.

Definition of Irregular Periods

There can be no simple definition of irregular periods due to the wide variation in what is considered a woman’s regular menstrual cycle. Changes in your usual cycle, whether that is brown spotting between periods, missed periods, more frequent periods, or flow that is heavier or lighter than usual can all be considered signs of irregular periods, if they persist for several months

Symptoms of Irregular Periods

The most common indicator of irregular periods is a shorter than normal interval between periods, often as little as two weeks. In other cases, symptoms of irregular periods during menopause may include more widely spaced periods, including menstruation that comes every six weeks – or even less frequently. Some women will even miss a period – or several in a row – before resuming their regular menstrual cycle.

Menstrual flow also is an indicator of irregular periods. Menstrual bleeding may last for as long as a week, or as little as 1-2 days. In some cases, the menstrual flow itself will vary, including lighter or heavier periods. For some women, physical symptoms may also accompany irregular periods during perimenopause, including unusual cramping, and blood clots that are more noticeable than usual.

Causes of Irregular Periods

Like most menopause symptoms, the primary cause of irregular periods is hormonal imbalance. Estrogen is the hormone that causes the lining of the uterus to thicken in preparation for ovulation. Progesterone is the hormone that signals the uterus to shed that lining if there is no fertilized egg to make use of it.

During perimenopause, a woman may have a cycle in which no egg is produced. In that case, progesterone is not produced either, which leads to higher than usual levels of estrogen. This build-up can result in heavier than usual periods, since the uterine lining may have built up over several months. Further hormonal imbalances can lead to irregularities in period duration, heaviness, and regularity.

Risks of Irregular Periods

One of the most important risks of irregular periods is the possibility of unwanted pregnancy. Many women incorrectly assume that their era of fertility has passed when they miss periods for several months in a row. However, until there have been no periods for at least a year, women should assume that they are still fertile and take appropriate measures to prevent unwanted pregnancy.
Irregular periods can also cause other symptoms related to erratic menstruation. Such symptoms can include severe pelvic cramping, back pain, frequent mood swings, fatigue, and ultimately, infertility in women.
