What Are Missed Periods?

Missed periods refer to the absence of menstrual bleeding when a period is expected. Missing one period occasionally may occur due to stress, illness, or hormonal fluctuations. However, missing periods repeatedly or for several months requires medical evaluation.

Pregnancy is the most common cause of missed periods, but when pregnancy is ruled out, other causes must be explored.

What Is Amenorrhea?

Amenorrhea is the medical term used to describe the absence of menstruation. It is diagnosed when periods are absent for a prolonged duration and are not related to pregnancy, breastfeeding, or menopause.

According to the American College of Obstetricians and Gynecologists (ACOG), amenorrhea should always be evaluated to identify the underlying cause.

Types of Amenorrhea

1. Primary Amenorrhea

This occurs when a girl does not start menstruating by the age of 15 despite normal growth and development.

2. Secondary Amenorrhea

This occurs when periods stop for three months or more in a woman who previously had regular cycles.

Causes of Missed Periods

Pregnancy
Hormonal imbalance
Polycystic Ovary Syndrome (PCOS)
Thyroid disorders
