Hormonal Imbalances

Menstruation or menses is regulated by an equilibrium of certain hormones mainly estrogen and progesterone. Any interference with this hormonal balance makes for irregular menstruation.

Stress And Lifestyle Factors

There is strong scientific evidence linking stress and menstrual irregularities.

Excessive amounts of cortisol, a stress hormone produced as a result of chronic stress can disrupt the levels of hormones needed for normal menstruation.

Additionally, lifestyle plays an important role in ensuring that menarche is consistent. Such lifestyle practices are excessive exercise, sudden weight fluctuations, and irregular sleep patterns. Though beneficial to regular health rigorous physical activity may result in anovulation (the absence of ovulation) thus interfering with the menstrual cycle.

Eating more fruits and vegetables together with whole grains and lean protein while taking appropriate supplements may help achieve hormone balance and menstrual regularity.

Medical Conditions

Another contributing factor to menstrual irregularities is endometriosis which is a pathological process whereby tissue similar to the lining of the uterus tends to develop outside the uterus. 

PID which is normally caused by sexually transmitted infections is also a factor for the reproductive organs as well as irregularities in the normal cycle of menstruation. Dealing with and treating these fundamental medical problems are necessary prerequisites to the resumption of a normal menstrual regimen and reproductive wellness. 

Birth Control Methods

Women who practice contraception especially hormonally may experience irregular menstruation. However, these pills, IUDs, contraceptive injections, or any other hormonal contraception may disrupt the normal menstrual cycle. However, it will influence the length of women’s periods as well as the blood flow that will occur after starting or stopping such means.

It is important to be aware of how various contraceptive options may impact menstruation when using a form of birth control. Therefore it would be prudent for women to talk about their problems while indicating what options work with their needs for their general well-being.
