As women enter into the time of peri menopause which is the time immediately preceding menopause and is a period of transition whereby women can experience symptom related hormonal changes that start to occur. As the ovaries become less productive the result is greater fluctuation in hormone levels. Most often this results in periods becoming irregular and menstruation unpredictable. Eventually periods end altogether and after 12 months without a period, women are officially considered menopausal. A small number of women become menopausal without experiencing irregular periods prior. For most women however, this is not the case. Irregular periods can be described as a variation to the usual menstrual cycle and can be distinguished by erratic bleeding episodes of abnormal bleeding with varying and degrees of length.
Hormonal imbalance or fluctuations can cause irregular periods especially at the time of menopause. The hormones Oestrogen and Progesterone decline at this time and this can be the cause of irregular periods. Women between the ages of 45 and 55 are the most likely to experience this change although some women may experience it at a younger age and some women when they are older.
One of the main functions of oestrogen is the thickening of the lining of the uterus. With the decline in oestrogen levels the lining may be shed erratically. This in turn can lead to heavy bleeding.
The other hormone known as progesterone, controls the level and extent of a menstrual bleed and is also responsible for the emptying of the contents of the uterus. The declining levels of progesterone can contribute to irregular periods.
Because these two hormones are important to the normal menstrual cycle, the declining levels result in irregular bleeding. The often, large variations cause irregular periods. While the imbalance of hormones in menopause is the main cause of irregular periods it is possible that other health conditions or lifestyle factors may also contribute to irregular periods.
