Menstrual periods usually start between the ages of 10 and 16 (during puberty), and continue being regular during whole reproductive period of women life. In most cases at 45-55 women are experiencing perimenopause and menopause, when menstrual periods just stop and women are ending their reproductive section of menstrual cycles.
During puberty menstrual periods can be irregular – periods can take up to two years to occur in a regular cycle. After puberty, the majority of females have a regular menstrual cycle – it means periods appear always after same period of time and usually duration of menstruation is also the same (the length of time between each period is similar and the duration of periods is same).
Some women have irregular periods – the time between periods, as well as the amount of blood shed varies considerably (intervals could be 2-6 months and even more and duration of the period could be 2-10 days). Sometimes women experience irregular periods starting from puberty (whole life) and some women can have irregular periods after having regular periods for long period of time (just triggered by stress, diseases, contraception, etc.). In all cases irregular periods could be considered as a signal for hormonal abnormalities triggered by several factors.
In most cases irregular periods could be a reason for infertility because very often (about 90% cases) women with irregular periods have anovulatory cycles (menstrual cycles without ovulation).
There are many factors which are responsible for irregular periods. Some of them you can find below:
A woman can have irregular periods due to significant weight loss or weight gain. You can discover more information about normal weight and anorexia in following pages.
Over exercise can also result in irregular menstruation.
Poor nutrition and diet which is rich in carbohydrates is also related to hormonal imbalance and menstrual disturbances.
Some drugs can also cause irregularities in menstruation.
Recent child birth or miscarriage are also one of the causes of irregularity.
Some women have period irregularities during breast feeding or hyperprolactinemia.
Women could experience irregular periods during perimenopause (menopause).
The above reasons can cause irregularities in menstrual cycle. If you find some reasons of irregular periods in yourself or your relatives and friend then it is a good idea to visit your doctor (by Jitesh Arora).
