Menstrual Cycle as a Vital Sign: Why It Matters in Women's Health

The menstrual cycle is more than just a monthly event ,it's a window into a woman’s overall health. Leading medical journals like The Lancet have advocated recognizing it as a vital sign, alongside temperature, heart rate, respiratory rate, and blood pressure. But despite this growing awareness, integration of menstrual data into clinical records remains rare.

What is a Vital Sign?

Vital signs are indicators that show how well the body is functioning. Traditionally, they include:

• Body temperature
• Heart rate (pulse)
• Respiratory rate
• Blood pressure

Adding the menstrual cycle to this list is a revolutionary yet logical step in modern medicine.

Why Menstrual Cycle is a Vital Sign

A healthy menstrual cycle reflects the balance of hormones, metabolism, immune function, and more. Changes in cycle length, flow, or regularity can indicate deeper issues.

Medical Conditions Associated with Abnormal Cycles

• Polycystic Ovary Syndrome (PCOS) – Irregular or absent periods
• Endometriosis – Painful, heavy periods
• Thyroid disorders – Affect cycle frequency and flow
• Eating disorders – Amenorrhea (lack of menstruation)
• Chronic stress – Can suppress ovulation

What The Lancet Says

In recent advocacy pieces, The Lancet has emphasized that menstrual health is not a luxury or side-topic. It is central to physical, emotional, and reproductive health. Integrating menstrual tracking into routine health assessments could dramatically improve early diagnosis of conditions.

Clinical Gap: Why Are Doctors Not Using This?

• Lack of standard tools to input menstrual data in electronic health records
• Social stigma and discomfort discussing periods
• Undertrained staff in menstrual health literacy
• Perception of menstruation as a non-essential parameter
