Pregnant black line

Linea Nigra: Should I Be Worried?

Medically reviewed by Holly Ernst, PA-C — By Stephanie Watson on February 21, 2019

Overview

Pregnancy can do weird and wonderful things to your body. Your breasts and belly enlarge, your blood flow increases, and you begin to feel movements from deep inside.

Around the middle of your pregnancy, you may notice another unusual change: a dark line running down the front of your abdomen. It’s called the linea nigra, and it’s no cause for alarm.

What causes linea nigra?

Your skin, like the rest of your body, goes through some changes during pregnancy. It stretches to accommodate your growing belly and breasts, and it may change color.

Most pregnant women notice darker patches of skin on their face, especially women who already have dark hair or skin. These patches of skin are called the “mask of pregnancy.”

You may also notice other areas of your body getting darker, like your nipples. If you have any scars, they might become more noticeable. Freckles and birthmarks may become more obvious, too.

These color changes happen because of the hormones estrogen and progesterone, which your body produces in larger amounts to help your baby develop.

Estrogen and progesterone stimulate cells called melanocytes in your skin, causing them to produce more melanin, the pigment that tans and darkens your skin. Increased melanin production is what makes your skin change color during pregnancy.

At some point during your second trimester, you may notice a dark brown line running down the middle of your abdomen, between your belly button and pubic area. This line is called the linea alba. You’ve always had it, but before your pregnancy it was too light to see.

When melanin production increases during pregnancy, the line gets darker and more obvious. Then it’s called the linea nigra.

What should I do about linea nigra?

Linea nigra isn’t harmful to you or your baby, so you don’t need medical treatment.

Some people believe that the linea nigra could send a signal about your baby’s gender. They say that if it runs to your belly button, you’re having a girl, and if it keeps going all the way to your ribs you’re due for a boy. But there isn’t any science behind the theory.

What happens to linea nigra after pregnancy?

Soon after your baby is born, the linea nigra should start to fade. In some women, though, it may never completely disappear. And if you get pregnant again, expect to see that line reappear.

If the line doesn’t go away after pregnancy and its appearance bothers you, ask your dermatologist about using a skin bleaching cream. That may help the line fade more quickly.

Don’t use a bleaching cream during your pregnancy or while you’re breastfeeding, because it can be harmful to your baby.

If the line really bothers you during pregnancy, try concealing the line with makeup until it fades.

Be sure to wear sunscreen whenever you expose your belly and other areas of your skin to the sun. Sun exposure can make the line even darker.

Takeaway

Linea nigra happens during pregnancy because your hormones trigger color changes in your skin. It’s not something to be worried about and usually fades after you give birth.

What to Know About the Pregnant Belly Line

Pregnancy can come with some unusual body changes, like hair in places you didn’t expect, sudden indigestion, hemorrhoids and acne breakouts. But here is a lesser-known surprise to add to the growing list of pregnancy pleasantries: Linea nigra. This dark line that can develop down the center of your bump may catch you off guard. So what is linea nigra, when does it appear and what can you do—if anything—to make it go away? Here’s what you need to know about the pregnancy line on your stomach.

What Is Linea Nigra?

Linea nigra, which is Latin for “black line,” is a streak running from your belly button to your pubic region that may develop and darken during pregnancy, according to the American College of Obstetricians and Gynecologists (ACOG). The length, width and color of this pregnant belly line varies from person to person.

Its appearance might make you do a double take, but it’s nothing to be concerned about. “Linea nigra is simply the increase in pigmentation of the skin,” says Julie Lamppa, APRN, a certified nurse-midwife at the Mayo Clinic and the author of Obstetricks. “Linea nigra can look slightly different on everyone,” and it may be more obvious if you have darker skin, says Christine Greves, MD, a board-certified ob-gyn at the Winnie Palmer Hospital for Women & Babies. People with darker skin have more melanocytes, which are pigment-producing cells, making them more prone to getting this line, explains Michael Cackovic, MD, a maternal-fetal medicine physician at the Ohio State University Wexner Medical Center.

It’s important to emphasize that this dark line on your stomach isn’t something that will impact you or baby. “Pregnant women can be reassured that linea nigra isn’t harmful and has no adverse effect on pregnancy outcomes or the baby,” says Jessica Shepherd, MD, an ob-gyn and founder of Sanctum Med + Wellness in Dallas, Texas. It’s just one of those things that you may (or may not) have to deal with for a while.

Does everyone get linea nigra?

While the linea nigra line is common, not every mom-to-be will get it. In fact, there’s no way to tell in advance if this is something you’ll develop during pregnancy. “We don’t know why some people get it and others don’t,” Greves says. Of course, having more pigment-producing cells may make you more prone to it, but it’s certainly not a guarantee. If you have linea nigra once, you’re probably going to have it in subsequent pregnancies too.

What Causes Linea Nigra?

Linea nigra is just one of the many skin changes that can happen during pregnancy. “Almost all pregnant women develop some type of hyperpigmentation in their skin in certain areas,” Cackovic says. For example, many pregnant women notice their areolas darkening or experience dark patches of skin that appear on the face, known as melasma. These melanocytes are likely stimulated by hormones like estrogen and progesterone, which surge in your body during pregnancy, Greves explains.

Unfortunately, there’s no definitive known way to avoid linea nigra. While you might not love the look of it, the important thing to remember is that it’s totally normal.

When Does Linea Nigra Appear?

This signature belly line can technically show up at any point in your pregnancy, but it will typically surface sometime in the second or third trimester, Lamppa says. Again, not everyone gets linea nigra. Either way, it’s no cause for stress.

What Is the Purpose of Linea Nigra?

While some physical changes that happen in pregnancy, like your breasts growing, have a biological purpose, experts say there’s no clear reason why your body would need to develop linea nigra. You can file this one under the many mysteries of pregnancy. “There’s no biological purpose for this,” Greves says.

Sorry to spoil your fun, but if you’ve heard an old wives’ tale that the length of your pregnant belly line will determine whether you’re having a boy or a girl, we’re here to debunk that myth. (It specifically claims that if the linea nigra starts below your belly button, you’re carrying a girl; if it extends above your navel, you’re supposedly having a boy.) While this is a fun guessing game to test out, Greves stresses that it’s not a legitimate way to determine baby’s sex.

When Does Linea Nigra Go Away?

If you’re wondering when the linea nigra will go away, you’ll have to be patient. There’s no clear-cut answer: The truth is, it depends. But in all likelihood, you’ll probably notice some changes in your skin soon after baby is born. “As hormonal levels start to decrease and stabilize, linea nigra should start to fade in the weeks and months after birth,” Lamppa says. Still, Cackovic adds that it can take up to a year or longer for linea nigra to fade in some people. What’s more, for others, this pregnancy line may never completely go away.

There are really no at-home remedies you can use to get rid of linea nigra during or after pregnancy. If it continues to linger after baby is born, consider seeing a dermatologist. Cackovic says they may recommend skin-lightening agents, chemical peels or laser and light therapies to try to get the line to fade. Another tip? Use a good SPF when your stomach is exposed. The sun’s UV rays can exacerbate patches of hyperpigmentation.

You may not be thrilled with the look of your pregnant belly line, but try not to focus on it, and be patient. “Remember that your body has amazingly grown a baby, and your body will never quite be the same—and that’s okay,” Lamppa says. The linea nigra is proof that you can do amazing things.

Why do women get a dark line on their belly during pregnancy?

Many expectant mothers notice that over time a dark vertical line appears on their stomach.

Some are so worried that they begin to get rid of it by any means, fearing that it will harm their health.

A dark vertical stripe on the abdomen (from Latin Linea nigra ) is one of the most common signs of pregnancy. This brownish line, usually about a centimeter wide, runs from the pubis to the navel, but sometimes it extends to the very top of the abdomen.

This vertical streak appears in most pregnant women and becomes fully visible around the 23rd week of pregnancy.

Why does a streak form?

Skin color often changes during pregnancy, dark spots may appear in different parts of the skin. Like other changes, the appearance of a strip on the abdomen is caused by an increase in hormone levels during the second and third trimester. It gradually gets darker.

By the way, there is another stripe, but white or a white line of the abdomen ( linea alba ), which stretches from the navel to the pubis and is present in all people.

However, the brown streak only occurs during pregnancy.

The appearance of a dark line during pregnancy is due to an increase in hormones that affect melanocyte cells, which ultimately leads to the production of more melanin, the pigment on which our skin color depends, that is, this pigment is to blame for everything.

It also causes age spots on the body, darkens the nipples, the skin in the perineum.

When does the dark line appear?

Most pregnant women notice a dark line between the first and second trimesters. And for expectant mothers who are expecting twins or triplets, the strip becomes visible already in the middle of the first trimester.

However, not all pregnant women develop this line. Studies have shown that this phenomenon is characteristic of 75% of expectant mothers.

When will the dark line disappear?

Dark lines on the abdomen disappear gradually after a few weeks after childbirth. If a woman is breastfeeding, then the strip will last for several months. In general, it takes time for the dark pigment melanin to stop accumulating in the cells.

Can the strip be dangerous for mother or baby?

This pigment line cannot pose any danger to the child. The fetus is completely protected from external influences. The only problem is that the streak is more pronounced in women with dark skin. This is usually caused by hyperpigmentation. But there is nothing to worry about here either. She, though slowly, but also disappears after childbirth.

Is it possible to predict the gender of the unborn child using the strip?

There is an old saying that if a woman has a brownish line passing through the center of the navel, then she will have a girl, and if the line passes by the navel, as if rushing around the navel, then there will be a boy. However, there are no scientific theories or studies to support this.

How to remove a dark line during pregnancy?

The appearance of a streak is a natural process, and there is no way you can get rid of it completely. However, you can follow some rules so that the skin does not darken even more.

Always wear closed clothing that protects the skin from direct sunlight.
Use a sunscreen with an UV protection index of at least SPF-30 to protect the skin from direct sunlight, for the face it is better to use creams with a maximum SPF-50. Do not sunbathe in the open sun.
Include foods rich in folic acid in your diet: orange juice, spinach, wheat, beans, drink enough liquid up to 2 liters per day, try to moisturize your skin with special creams.

There is absolutely no need to lighten this area, especially at home, otherwise it can lead to skin burns.

If age spots appear on the face, it is worth contacting a dermatologist who will advise what to do in this case so as not to harm yourself and the baby in the womb in the first place.

Remember that there is nothing wrong with the appearance of linea nigra on the stomach. Most importantly, make sure you eat and rest properly, and the strip will disappear on its own in a few months after the baby is born.

Dark stripe in pregnant women: statistics

During pregnancy and after childbirth, many processes in a woman's body are rearranged. Often, pigmentation and vascular network appear on the skin.

According to statistics, this phenomenon is typical for 75% of expectant mothers.

Increased skin pigmentation usually occurs in certain areas on the body. Most often, the line from the pubic symphysis to the navel or the xiphoid process of the sternum darkens. It is also called the "stripe on the abdomen in pregnant women. " For a child, this pigment line does not pose any danger.

The skin of the areola, nipples, armpits, perineum, inner thighs and neck also darkens. Fresh scars from surgeries shortly before pregnancy may also become more visible.

Why do pregnant women get a stripe on the stomach

It is not completely known what causes increased pigmentation. There is speculation that this is due to the fact that estrogens and progesterone stimulate the production of melanocytes - special skin cells that are responsible for skin color and tanning. In those areas of the body where there are more of these cells, pigmentation is more noticeable. In rare cases, during pregnancy, a woman's entire skin becomes darker. But here there is rather another reason - perhaps this is how the disease associated with adrenal dysfunction manifests itself.

When the dark line appears during pregnancy

Most often, the dark line on the abdomen in pregnant women becomes clearly visible in the second trimester. If a woman is expecting twins or triplets, then the line will be clearly visible already in the middle of the first trimester.

Is it possible to make this line lighter

Nothing needs to be done about pigmentation during pregnancy - this is a completely natural and short-term process. If there are thoughts to get rid of the dark strip on the stomach with a cream, then this is also not necessary. Lightening agents will not help, and excessive use of them can lead to skin burns.

But, if during pregnancy you are worried about the strip on your stomach, you can follow some rules so that the skin does not become darker:
