Light periods refer to menstrual periods that have very light flow and are characterized by a lesser number of days than usual. Although the menstrual cycles vary from a woman to another, the duration for a normal period is around every 28 days. Each period lasts for approximately four to seven days. The amount of blood loss in a normal period is around 20 ml to 80 ml. However, loss of blood below 20 ml can be considered as light periods.
The causes of light periods can vary for different woman. Some of them are:
- An imbalance in hormone levels in the body like PCOD (polycystic ovarian disease).
- Light periods are most common in women who are approaching menopause. This is because, at this time, women tend to produce less estrogen, a hormone responsible for regulating menstrual periods.
- Light periods can be common in girls who have just started to menstruate.
- Excessive bouts of exercise, a thyroid condition or an eating disorder can be also responsible for light periods in women.
- Women who use hormonal or oral contraceptives may also have a chance of experiencing light periods.
- An important cause of scanty menses is implantation bleeding. That means sometimes, despite being pregnant, little amount of bleeding can happen at the expected time of menses in the first three months of Pregnancy. So it's important to rule out pregnancy at the earliest.
