What Does The Brown Color Of Menstruation Mean?

Blood tones during menstruation can vary greatly; however, the brown tone does NOT always mean that everything is fine; Nor is it a very serious issue.


This state of constant tension can cause the lining of the uterus to compress and hinder the expulsion of endometrial cells, causing blood to oxidize and take on that color.

Nutritional deficiencies

The lack of nutrients in the body, as a result of poor diet, may be responsible for this alteration of tonality. It is important to know that prolonged malnutrition can cause amenorrhea, which is the absence of menstruation.

Implantation bleeding

It occurs when the fertilized egg adheres to the wall of the uterus and certain veins that supply the endometrium are broken and this causes dark bleeding, which lasts three to four days.


Not every month the cells are expelled in a period, so they are "stored" and are expelled in the next cycle, by a brown flow.


The use of these, especially oral ones, can have as a side effect the change in the color of the menstrual flow, due to hormonal mismatch. The use of the IUD can also generate this change in tone, along with irregular menstrual cycles and abundant flow.

Sexually transmitted diseases

Sexual diseases caused by bacteria such as gonorrhea or chlamydia, cause a more rapid degradation of the menstruation blood, making the menstrual blood darker. In addition to this, this type of menstruation is usually accompanied by a foul odor, brown flow before or after menstruation, belly or pelvic pain and fever above 38º C.


Another situation in which the dark menstruation is normal, is in the postpartum period in which the uterus takes about 45 days to return to its normal size, causing bleeding throughout this period. In this phase the bleeding is not exactly menstruation, but the coloration is dark and can confuse many women, but it is not of concern since this is a normal and expected situation.

Hormonal disorders and menopause

When hormonal alterations caused by thyroid problems or even menopause arise, it is very common for menstruation to be dark and in a small amount. This alteration is also very common when changing birth control pills or when the woman is no longer breastfeeding very often, and the birth control pill that is used during breastfeeding is not enough so that there is no bleeding.

Before any change in your menstruation, it is important that you go to review with your gynecologist as soon as possible.

    What if I'm not bleeding at all? I would usually have my period by now. It doesn't always come on the same day, so it's hard to say exactly how late it is, but it's definitely late. Usually my doctor says don't worry about it unless it goes past 2 weeks. Sometimes I wake up and it feels like I have it but there's nothing when I check. Usually when I have this problem, I'm either going on or off birth control. I'm not on anything and it's impossible for me to be pregnant because I'm not active and haven't been in a while. Everything has been fine since going off the pill. My period regulated itself and I haven't had any problems since. Until now. I went off it a while ago. What's going on?
