Is it normal to have a black line on your belly during pregnancy?

Some mothers have a black line on their belly during pregnancy, which is normal. It is caused by hormonal changes during pregnancy, which leads to skin pigmentation. The belly, especially between the pubic symphysis and the navel, is a common site for this.

This line has no practical significance and usually does not persist like stretch marks and melasma. It will disappear naturally six months to a year after giving birth. Don't worry.

Why is there a black line on the belly during pregnancy?

1. Progesterone imbalance

During pregnancy, the uneven secretion of estrogen and androgen in the pregnant woman's body will cause melanin precipitation, and the pregnancy line will become darker and thicker.

If the pregnant woman has thick hair and dark skin, the pregnancy line formed will be very dark and relatively thick.

If the pregnant woman has less hair and fair skin, the pregnancy line formed will be light in color, narrow and small, which is related to the pregnant woman's own physical constitution.

2. Important anatomical landmarks

Before a woman becomes pregnant, there will be a physiological curve on her abdomen that is lighter in color. After pregnancy, the color of this midline of pregnancy will become darker and darker. The midline of pregnancy is also an important anatomical landmark. When a woman has a caesarean section, the doctor will perform the operation based on this midline of pregnancy.
