How much blood should one lose during their period and how is too much?

On average, a person loses between 2 and 5 tablespoons (30–70 milliliters) of blood during a period. However, some people may lose more or less than this amount.

There are a few factors that can affect how much blood you lose during your period, including:

* Your age: Menstruation tends to be heaviest in the early years of menstruation and then gradually decreases as you get older.

* Your menstrual cycle: Some women have heavier periods than others, and some periods are heavier than others within the same woman.

* Your hormones: Hormonal imbalances can cause heavier periods.

* Certain medical conditions: Some medical conditions, such as uterine fibroids or adenomyosis, can also cause heavier periods.

If you're concerned about how much blood you're losing during your period, talk to your doctor. They can help you determine if your bleeding is normal or if there may be an underlying medical condition that needs to be treated.

Here are some signs that you may be losing too much blood during your period:

* You need to change your pad or tampon every hour or two

* You bleed through your pad or tampon within an hour

* You have large blood clots that are larger than a quarter

* You're feeling very tired or lightheaded

* You have difficulty breathing

* You're experiencing abdominal pain that doesn't go away

If you experience any of these symptoms, it's important to see a doctor right away.
