Irregular periods: Causes, Complications, and Treatment

Irregular periods: Causes, Complications, and Treatment

A female body prepares itself for pregnancy every month. During this time, one of your ovaries passes an egg to the fallopian tube, where it awaits the event of fertilisation with healthy sperm.

However, when that doesn’t happen, the uterus lining sheds. This is called menstruation or periods, and the process repeats every month, typically every 28 days.

However, many women experience irregular periods which in most cases isn’t indicative of a serious problem. It is important to understand what’s causing it and when to seek medical attention.

This article explains everything you need to know about irregular periods.

 

What are irregular periods?

If the gap between your monthly menstrual flow keeps changing, you might have irregular periods. While it’s normal for periods to occur a little early or late, certain signs indicate when it’s important to consult a gynaecologist.

Those signs are:

  • You are below the age of 45, and your periods have become irregular all of a sudden
  • The gap between your menstrual cycles is often less than 21 days or more than 35 days
  • Excessive bleeding during menstruation
  • Periods that last more than seven days
  • You are unable to get pregnant due to irregular periods

By consulting a gynaecologist, you will also find out the cause of your irregular periods. Some of the common causes are discussed next.

 

Causes of irregular periods

Numerous reasons for irregular periods are there, including:

  • Natural hormonal changes
  • Birth control
  • Underlying health conditions

Let’s understand them one by one.

 

1. Natural hormonal shifts

Irregular periods can occur due to natural hormonal changes. The main hormones that regulate your menstrual cycle are follicle-stimulating hormone (FSH), progesterone, and estrogen.

Any disruption in the usual rise and fall of these hormones can lead to irregular periods.

Factors that may alter the hormone levels are:

  • Stress
  • Extreme weight gain or weight loss
  • Early pregnancy: a simple pregnancy test will confirm it
  • Puberty
  • Excessive exercise

It is common and natural to have irregular periods during puberty when the body undergoes many changes. During those years, the periods tend to be longer and irregular. It takes several years before they become shorter and regular.

Apart from that, you can also have menstrual irregularity after childbirth, as it takes some time for your hormones to return to normal. Breastfeeding, in particular, is associated with suppressed ovulation.

When your periods stop because of frequent breastfeeding, it’s called lactational amenorrhea. It usually lasts three to six months or longer. Another natural cause of irregular periods is perimenopause.

In most women, perimenopause lasts four to seven years before they hit menopause, i.e., complete cessation of their menstrual cycle. During this phase, the estrogen and progesterone level continues to fall.

 

2. Birth control

One of the causes of irregular periods is oral contraceptives. They prevent pregnancy by reducing or stopping ovulation. You won’t have a true period if you are using birth control. In fact, you might not have a period at all.

While on birth control, you can experience withdrawal bleeds. However, this should not be mistaken for menstruation.

A drop in your hormone levels triggers it, and when that happens, some mucus and blood from your uterus lining are shed through the vagina.

Other forms of birth control can also lead to withdrawal bleeds, including intrauterine contraceptive devices (IUD), vaginal rings, and birth control patches.

The withdrawal bleeds usually last a few days or a few weeks. It differs for every woman. Over time, it becomes more regular or stops entirely.

Similarly, you can have irregular periods after stopping birth control. Typically, women experience withdrawal bleeds for two to four weeks before resuming menstruation.

However, it may take three to four months before they become regular.

It’s important to note that if you had an irregular pattern before using oral contraceptives, it’s normal for you to return to an irregular pattern again after stopping the usage.

 

3. Underlying health conditions 

Sometimes, irregular periods are indicative of an underlying health condition, such as:

  • Polycystic ovary syndrome (PCOS): The formation of fluid-filled sacs in the ovaries causes this chronic condition, and irregular periods are one of the symptoms
  • Eating disorders: Certain eating disorders like binge eating, anorexia, and bulimia nervosa can lead to irregular or absent periods
  • Thyroid disease: Both hyperthyroidism (excessive thyroid hormone) and hypothyroidism (insufficient thyroid hormone) are associated with irregular periods; it can also cause the flow to be too light or heavy
  • Premature ovarian failure (POF): When ovaries stop releasing eggs before age 40, it’s likely due to premature ovarian failure; it causes irregular periods or premature menopause in women
  • Hyperprolactinemia: The excessive level of prolactin protein is known as hyperprolactinemia, which is one of the reasons for irregular periods

Other conditions such as type 1 diabetes and congenital adrenal hyperplasia (disorders of the adrenal gland) can also cause menstrual irregularity.

 

Complications 

Irregular periods can lead to other complications, such as:

  • Iron deficiency: Frequent or heavy periods may cause you to develop iron deficiency.
  • Infertility: Conditions such as PCOS and POF are major reasons for infertility.
  • Osteoporosis: Reduced estrogen in your body contributes to osteoporosis (brittle or weak bones).
  • Cardiovascular diseases: Lack of estrogen increases the risk of cardiac diseases.

All of these conditions require medical attention as well.

 

Irregular periods treatment 

Most natural causes of menstrual irregularity, such as perimenopause and childbirth, don’t require any treatment. Irregularity due to birth control pills, patches, or IUDs also doesn’t need medical attention.

However, if your irregular periods have been persistent and you are below the age of 40, it’s wise to see a doctor who will determine the underlying problem.

Your treatment options may include:

  • Hormone therapy: This is typically recommended by doctors to manage PCOS symptoms
  • Nutritional therapy: A dietician will advise a suitable nutritional therapy if you are living with an eating disorder that causes irregularity
  • Mental health support: Since stress, eating disorders, depression, and anxiety are linked with irregular periods, you may require psychological support
  • In vitro fertilsation (IVF): If irregular periods are causing infertility and you’ve been trying for a while, IVF is an option worth considering; doctors use this technology to artificially extract your egg and fertilize it with your partner’s or donor’s sperm

 

Certain lifestyle changes and home remedies can help you get periods regularly, including:

  • Maintaining a healthy weight
  • Exercising
  • Adding cinnamon and ginger to your diet
  • Taking adequate Vitamin D

 

Conclusion

Irregular periods are menstruation flows that are unpredictable and change in length and/or frequency. Working with your doctor to determine the cause of irregular periods is important.

Some women have them because of a condition called Polycystic Ovarian Syndrome (PCOS) which can cause infertility. Menstrual irregularity is not a problem for everyone, but for some women, it is a serious issue that can affect their quality of life.
