What is the cause of brown blood periods?

I have noticed that my periods are producing brown blood instead of red.

My OB/GYN told me that it's nothing to be concerned about if you've got brown menstrual fluid instead of red because it's simply the age of the cells that make the difference. I get the impression that if the uterine lining is loose for a bit before sloughing off it can cause the cells to turn brownish.

Most "brown" blood is from old mentrual fluid. During your previous cycle, your uterus did not expel all the lining and the blood content was left. When the next cycle begins, the older lining is shed giving it the brown appearance.

Brown blood indicates old blood which means it is left over tissue from your last period or at the end of your period, this cycle.

This is very common for menstruating women, and is nothing to worry about. Brown blood is simply older blood. It is most common towards the end of your period. If your period is especially light, this may occur as well. Whether you have a light or heavy period, this is extremely normal. Don't worry.

Brown blood during your period is usually not a cause for alarm. When you menstrate, sometimes all of the blood is not released. Bright red bleeding is due to fresh shedding of the uterine walls. Brown blood is the older blood that may not have been released in your previous cycle. Good luck!

Blood turns brown when it is exposed to air. This is why blood dries brown on clothing. So the possible cause of having brown blood in your period is that the blood is not coming out very fast or is remaining on the outside of your body longer before release.

If your blood is brown, it is probably due to what is called "old blood." This can be due to there being residual blood from your last period or stress.
