effects of irregular periods on body

Irregular periods can greatly impact the overall health of a person.

While often viewed as a mere inconvenience, the effects of irregular periods on body have far-reaching consequences.

On one hand, they can be a sign of something even more serious, while, on the other, irregular periods can lead to several health issues.

Having an appropriate management strategy is important to tackle irregular periods.

Let us look at the effects of irregular periods on the body and discuss what can be done to counter its effects. 

What are irregular periods

Irregular periods (Oligomenorrhea) refer to inconsistent menstrual blood flow.

Some menstrual irregularities are expected at postpartum, menarche, or in the perimenopausal time.

However, under normal conditions, if a person reports menstrual cycles for more than 35 days for four to nine cycles a year, it is termed irregular periods.

It is estimated that 14-25 percent of women in the general population suffer from irregular periods.

Causes of irregular periods

Irregular periods are often associated with disorders that include:

  • Polycystic Ovarian Disorder 
  • Androgen-secreting tumors
  • Problems in the Hypothalamus (a part of the brain)
  • Contraceptive pills side effects

Studies have shown that people with obesity, less sleep, and more exposure to stress were also more likely to suffer from irregular periods.

Poor quality sleep of less than five hours daily is associated with irregular menstrual cycles.

Moreover, menstrual irregularities are linked with high perceived physiological stress.

Furthermore, factors like smoking can also lead to irregular periods.

Engaging in activities like smoking can affect your reproductive health.
Besides irregular periods, smoking and high cigarette use can cause premature Menopause in the long run.

What do irregular periods do to your body

Irregular periods are not normal in the body and usually can result in side effects.

The following are some of the effects of irregular periods on the body that you must watch out for.


Irregular periods are often related to more serious underlying conditions like Polycystic Ovary Syndrome (PCOS), which can cause infertility.

The hormonal imbalances causing irregular periods can also make pregnancy difficult.

Polycystic Ovary Syndrome (PCOS) is a condition when the ovaries produce an abnormally high amount of Androgens from small cysts that can develop on the surface of the ovaries.

Thickening of the uterus lining

Irregular periods causes an imbalance of the Estrogen and Progesterone levels in the body.

The imbalance of these critical hormones can cause gradual thickening of the uterine walls (Endometrial Hyperplasia).

Endometrial Hyperplasia

Sometimes, the thickening of the uterus lining can lead to Endometrial Cancer.

Moreover, studies have shown that those who experience irregular periods are more likely to develop Endometrial Cancer later in life.
