Irregular Periods: 5 Common Causes Women Should Be Aware Of

When menstruation arrives earlier or later than expected, or doesn’t occur at all, it is known as irregular periods or abnormal menstruation. Many women experience this issue at different stages in life, and it can sometimes point to underlying health concerns. Here are five common causes:

1. Hormonal Imbalance

Estrogen and progesterone regulate the menstrual cycle. When these hormones are out of balance, it can lead to irregular periods. Thyroid dysfunction is another factor that affects hormone levels, contributing to menstrual irregularities.

2. Obesity or Sudden Weight Changes

Gaining or losing a significant amount of weight can disrupt your menstrual cycle.

Overweight women may produce more estrogen, which can delay or stop ovulation.

Underweight women may lack sufficient body fat, affecting hormone production and ovulation.

3. Polycystic Ovary Syndrome (PCOS)

PCOS is a hormonal condition where small cysts develop on the ovaries. This leads to:

Hormonal imbalance

Irregular or missed ovulation

Delayed or infrequent periods

It's one of the leading causes of irregular menstruation among women of reproductive age.

4. High Prolactin Levels

Prolactin is the hormone responsible for milk production after childbirth. However, elevated prolactin in non-pregnant women can:

Disrupt ovulation

Cause irregular or missed periods

This condition may require medical evaluation and treatment.

5. Anemia

Anemia is common in women, especially those with heavy menstrual bleeding. Low hemoglobin levels can affect overall health, including the regularity of menstrual cycles.

Treating anemia promptly can help restore menstrual balance and prevent ovulation issues.
