Light menstruation

What is a light menstruation?

Light menstruation, also known as hypomenorrhea, means that blood loss is less than average. This can range from just a few drops a day to a short period of one or two days. Some people experience this as normal, while for others it may be a sign of an underlying cause.

Characteristics of light menstruation

• Less than 30 ml of blood loss per cycle (normal is 30-40 ml).
• Menstruation lasts less than 2 days.
• Sometimes only light spotting instead of actual bleeding.

Causes of light menstruation

• Hormonal changes, such as low estrogen levels.
• Use of hormonal contraception, such as the pill or hormonal IUD.
• PCOS or thyroid problems.
• Stress, weight loss or intense training.
• Perimenopause, the transitional phase before menopause.

When should you see a doctor?

If your period suddenly becomes much lighter for no apparent reason or if your cycle becomes irregular, it may be wise to consult a doctor.
