While the average age of menopause is around 50, every woman’s body has its own unique timeline. Some women stop menstruating in their mid-40s, and others continue well into their mid-50s.

No, your body burns calories the same whether you are menstruating or not. Most of what happens to your body during your period is hormone related and not caused by muscle contraction, so you aren’t really doing any extra work in your body.

Who else finds it hard to believe that you lose aprox. 28 gallons of blood from periods in a lifetime?

Q: Do the math- aprox. 13 periods a year for aprox. 37 years (age 13-50 is average) and you bleed up to a cups worth each period. That’s 461 cups aka 28 gallons!OMG! That’s crazy! Women have it so hard. THE QUESTIONS IS: How can we bleed that much and not die?PS. i subtracted 20 cups from what the answer was if you bled a cup EVERY period, because I’m sure we don’t for every one.

A: Yeah that is crazy!But thats why guys say that girls have magical tricks:We bleed without a cut,We get wet without water,And we make things without bones hard.lol some guy told me that once…

Why do women have periods? Isn’t it a shocking waste of nutrients?

Q: Why couldn’t the lining of the uterus be re-absorbed or just remain in readiness rather than being shed each month? How many calories/other nutrients does a woman waste over her lifetime in lost blood from her periods, on average? Is there an evolutionary reason why human females bleed? (NB I am posting this in biology, not religion, I do not want a religious debate on evolution in this thread please. There are plenty of other questions for that!).Do any other animals bleed to the same extent?Thanks to those of you who have tried to answer this question, but please, don’t waste your time unless you actually KNOW the answer. I am a scientist myself (PhD biology and 10+ years research experience) and don’t know this. I hoped there might be someone with expertise in the field of human reproduction on here…? Thanks again for your sensible replies.

A: I’m not exactly an expert, but I thought I should just pitch in my two cents’ worth anyway. =pThe lining is quite thick by the time it is at its peak. Simply reabsorbing it would be really complex and take a long time. After all, the only way to go is by apoptosis and if the whole lining underwent apoptosis at once or too rapidly, the signals release would just trigger a massive immune response, leading to a greater waste of resources (energy, nutrients etc). All that free nutrients from the cell debris could also be potential sources of nutrients for pathogens.Also, if the lining were to be left there rather than being reabsorbed or released, it would probably be more energetically demanding.Although cats and dogs reabsorb their lining, I’m guessing that their lining is much much less than humans, which might explain why they reabsorb rather than bleed it out. However, it’s possible that menstruation happens in humans because it allows the females to be sexually active whenever they want to, rather than to be “in heat” like estrous animals.Oh, and menstruation is accompanied by diapedesis and loss of leukocytes. This could be part of the reason for menstruation, such that the leukocytes would help to clear off any bacterial or fungal growth that might be present.
