Menstrual Cycle: Phases & Their Importance

The menstrual cycle refers to the regular, natural process that occurs in the female body, in which the uterus prepares itself for potential pregnancy. It typically lasts about 28 days, but can vary from person to person. During the menstrual cycle, hormones such as oestrogen and progesterone rise and fall, causing the ovaries to release an egg (ovulation), thickening of the uterine lining, and then shedding of the lining if fertilisation doesn't occur. The shedding of the uterine lining is what causes menstruation, or a woman's period. The menstrual cycle is an important aspect of reproductive health and is essential for fertility.

Understanding Menstrual Cycle 

The menstrual cycle can be broken down into several phases:

  • Menstrual Phase: This is the phase during which the uterus sheds its lining, resulting in bleeding for a period of 3-7 days.
  • Follicular Phase: This phase begins on the first day of menstrual bleeding and lasts for approximately 14 days. During this phase, follicles in the ovaries begin to mature and produce oestrogen, which stimulates the growth and thickening of the uterine lining.
  • Ovulation Phase: This is the phase during which the matured follicle releases an egg from the ovary, which travels through the fallopian tube towards the uterus. This typically occurs around day 14 of the cycle, but can vary.
  • Luteal Phase: This phase begins after ovulation and lasts for approximately 14 days. The ruptured follicle in the ovary turns into a structure called the corpus luteum, which produces progesterone. Progesterone prepares the uterine lining for potential implantation of a fertilised egg.

If fertilisation does not occur, the corpus luteum will break down and hormone levels will drop, leading to the shedding of the uterine lining and the start of a new menstrual cycle.

It's important to note that the length and regularity of the cycle can vary from person to person and can be affected by factors such as stress, weight changes, hormonal imbalances, and certain medical conditions. If you have concerns about your cycle, it's a good idea to speak with your healthcare provider.


Importance of Menstrual Cycle 

The menstrual cycle is important for several reasons:

  • Reproduction: The cycle plays a crucial role in reproduction, as it prepares the female body for potential pregnancy. Without a regular menstrual cycle, a woman may have difficulty conceiving.
  • Hormonal balance: The hormones involved in the menstrual cycle, such as estrogen and progesterone, help regulate many bodily functions, including bone health, mood, and energy levels.
  • Health monitoring: Changes in the cycle can be an early indication of potential health issues, such as hormonal imbalances, thyroid problems, or polycystic ovary syndrome (PCOS). Tracking your cycle can also help you identify irregularities and potentially seek medical attention if needed.
  • Empowerment and normalisation: Understanding your cycle and talking openly about it can help reduce stigma and empower women to make informed decisions about their reproductive health.

Overall, the menstrual cycle is an important aspect of reproductive and overall health. If you have any concerns about your cycle or reproductive health, it's always a good idea to speak with your healthcare provider.

Problems causing improper menstrual cycle and how to overcome them?

There are several factors that can cause an irregular or improper menstrual cycle. Some of these include:

  • Hormonal imbalances: Hormonal imbalances can cause irregular menstrual cycles. This can occur due to conditions such as polycystic ovary syndrome (PCOS), thyroid dysfunction, or even stress.
  • Weight changes: Significant weight gain or weight loss can disrupt the menstrual cycle. This is because excess body fat can produce hormones that can interfere with the normal cycle.
  • Certain medications: Certain medications, such as hormonal contraceptives or medications used to treat other health conditions, can affect the menstrual cycle.
  • Menopause: As women approach menopause, their cycle can become irregular and eventually stop.
Menstrual Cycle: Phases & Their Importance

To overcome irregular cycles, it's important to first identify the underlying cause. If the cause is a medical condition, your healthcare provider may recommend specific treatments or medications. In other cases, lifestyle changes may help regulate the cycle. These may include:

  • Maintaining a healthy weight: Maintaining a healthy weight can help regulate the cycle and improve overall reproductive health.
  • Managing stress: Stress can interfere with hormonal balance and disrupt the menstrual cycle. Managing stress through techniques such as meditation or exercise can be helpful.
  • Hormonal contraceptives: Hormonal contraceptives such as birth control pills or hormone-containing intrauterine devices (IUDs) can help regulate their periods.
  • Surgery: In some cases, surgery may be necessary to address underlying health conditions that are affecting the cycle.

It's important to speak with your healthcare provider if you have concerns about your menstrual cycle. They can help determine the underlying cause and recommend appropriate treatments or lifestyle changes.
