Why do women get tired when they get their periods? It doesn't seem like the blood lost would do that.?

Answer 1

Its hormonal. Estrogen fades as you get ready to start a period. Estrogen helps keep insulin under control. Insulin, thus, can go wild. The purpose of insulin is to open the "cell's mouths" to let food and water in. Thus, right before your period, insulin is madly tucking food and water in cells, causing bloating and weight gain.

The food insulin tucks in cells is blood glucose. If there is too much insulin (a condition known as hyperinsulinemia), it can result in there being too little blood glucose in the blood stream for the rest of the body to use during the day (a condition known as hypoglycemia). If the brain senses a low blood sugar condition, it requests food, but if you don't eat, it starts to slow the body down to conserve energy, causing tiredness.

Answer 2

I think it is the stress on your body during your period. Your whole body goes through changes, and your hormones add to the stress. I know that blood loss can make you tired, due to the loss of iron. So if you have a heavy flow it could be possible to be tired from that. I generally feel tired right before I start, so I think it has to do with hormone levels.

Answer 3

It's hormones.

The blood "lost" isn't really like bleeding, it's the old uterine lining coming out as it replaces itself.

Answer 4

Its not because of the blood loss, I think it is because of your body working to get it out... im not sure.

If you were in pain with cramps you wouldn't feel comfortable doing anything either.
