Brown pregnancy line: where does it come from?

A brown line suddenly appears on your rounded stomach? Rest assured, this is a completely normal phenomenon. About 3 out of 4 women observe this line during their pregnancy from the second trimester. Also called “linea nigra”, it results from hormonal changes and disappears after childbirth . Discover all the secrets of this brown pregnancy line and our mother-to-be treatments to pamper you!

Why do we have this pregnancy line?

The brown line of pregnancy, also called “linea nigra”, is a vertical band of dark brown pigmentation . It extends from the navel to the pubis with a width of approximately one centimeter: a sort of small vertical border in the middle of your stomach! Apart from its unsightly side, this pregnancy line does not represent any danger, neither for the mother-to-be, nor for the baby.

But why this band on your rounded stomach? Once again, your hormones are to blame! During pregnancy, the placenta secretes a quantity of the Melanotropic hormone , responsible for the synthesis of melanin. Result: the melanin present on your skin comes out and draws this line on your stomach. The pregnancy line is therefore more marked in women with dark skin. It is also this hormonal phenomenon which explains darker nipples and the appearance of the mask of pregnancy!

Girl or boy ?

According to some beliefs, the brown pregnancy line allows you to know the sex of the baby . So myth or reality? According to adages, the “linea nigra” is very marked in women if they are expecting a little boy. Of course, this is a matter of individual beliefs and is not scientific. Only the second trimester ultrasound reveals with certainty the sex of the future baby!
