Should You Be Concerned About Heavy Bleeding?

Every woman’s period is different. What seems normal for one woman may be out of the ordinary for another. While some women have light periods that cause no reason for concern, others may have heavier periods that not only interfere with their daily activities but might also signal an underlying problem.

What’s normal for you depends on your body. How do you tell the difference between normal menstrual flow and a period that is too heavy? Read on to find out.

What is “normal” anyway?

What constitutes a “normal” period varies from woman to woman. However, the typical period lasts from 2-7 days and the average menstrual cycle, which starts on the first day of your period, is anywhere from 21-35 days. Cycles tend to shorten as you age.

Most women experience a regular cycle that occurs at the same time each month and a light, moderate, or heavy flow that falls within the broad “normal” range. Flow tends to vary during the 2-7 days of your period, with the first day or two being heavier. Many women experience a lighter flow toward the end of their period.

Is there such a thing as “too much”?

Even though there is a broad range of what is considered to be normal, there is such a thing as too much menstrual flow. The medical term for heavy or prolonged periods is menorrhagia.

The average woman loses about 30-40 milliliters of menstrual fluid during her period. That’s about 2-4 tablespoons.

While there’s debate about what amount of blood loss is classified as heavy, most experts consider your period to be heavy if you lose more than 60 milliliters of fluid per cycle.

Because it’s difficult to measure your flow, here are some good indicators to tell whether your menstrual flow is too heavy:

Health conditions that cause heavy periods

While heavy menstrual flow usually isn’t serious, it can sometimes signal underlying health problems. The following conditions can cause heavy periods:

Keep in mind that perfectly innocent things can cause heavy bleeding, such as stress or changes in diet.
