Menstrual Irregularities

Most women suffer menstrual irregularities at some point, especially during perimenopause and menopause. While this is natural in many cases, it's important to understand what's natural, and what's cause for concern.

Menstrual irregularities can be caused by various factors

What Are Menstrual Irregularities?

Normally, menstrual cycles remain consistent. Their duration may vary between women, but typically lasts between 21 to 35 days, with menstruation between three to five days. Regular is defined as having your periods occur at roughly the same date each month. During certain stages of a woman's life - for example, perimenopause, and puberty - the frequency of periods starts fluctuating considerably, making them extremely difficult or even impossible to keep track of.

Another type of menstrual irregularity is known as anovulatory periods. It means the body doesn't properly develop and release a mature egg every month. Understanding why menstrual irregularities occur can help you manage the problem effectively.

What Causes Menstrual Irregularities?

During menopause, menstrual irregularities are generally caused by hormonal imbalances. However, there can be a variety of other reasons, such as:

  • Anxiety
  • Stress
  • Fatigue
  • Significant weight gain or loss
  • Over-exercising
  • Smoking
  • Drug use
  • Caffeine
  • Alcohol abuse
  • Certain medications
  • Underlying disorders
  • Poor diet.


Hormones like estrogen and progesterone regulate the menstrual cycle by determining when ovulation and menstruation occur. Without a balanced level of these hormones, women are unable to properly ovulate and experience menstrual irregularities.

How Can I Manage Menstrual Irregularities?

The first step in managing menstrual irregularities, first, try to identify the cause of them. Are you working too hard? Do you feel stressed or anxious? Have you lost or gained a lot of weight? These are all questions you should ask because hormonal imbalance can result from certain lifestyle habits. It may be that you need to relax more by practicing yoga or deep breathing exercises. Take a look at your diet and make sure you get enough nutrients.

However, during menopause, irregular periods are almost always due to hormonal shifts, which occur naturally. There are several options to regulate hormone levels such as:

  • Regular exercise. This will keep your body healthy and help your hormones stay balanced.

  • Eating healthy. Complex carbohydrates, fruit, and vegetables are all essential to give you all the necessary nutrients and vitamins for proper hormone production.

  • Alternative medicine, like herbal supplements, can help alleviate symptoms.
