During pregnancy, many people notice a dark, vertical line on their abdomen. This line is called the linea nigra. It usually appears around the middle of pregnancy, but it can also show up in men, children, and women who aren’t pregnant.
If you’re wondering why this line appears and what you can do about it, keep reading to learn more.
What Is a Linea Nigra?
The linea nigra is a dark, brownish line that runs vertically down the abdomen. It’s usually about 1/4 to 1/2 inch wide and most often appears between the belly button and the pubic area. Sometimes, it can extend above the belly button.
This line is always present but is usually light and invisible. When it darkens, it’s called the linea nigra. During pregnancy, hormonal changes can make the line more noticeable.
Who Gets a Linea Nigra?
While the linea nigra is most common during pregnancy, it can appear in:
- Pregnant women: About 92% of pregnant women develop this line.
- Non-pregnant women: Around 16% of non-pregnant women may also have it.
- Men and children: It can appear in men and children too.
Why Does the Linea Nigra Appear?
The exact reason isn’t fully understood, but hormones are believed to play a big role.
1. Hormonal Changes
- During pregnancy, hormones like estrogen and progesterone increase. These hormones can stimulate melanocytes, the cells that produce melanin (the pigment that darkens skin).
- This extra melanin can darken areas of the skin, including the linea nigra.
2. Medications and Environmental Factors
- Birth control pills or other medications that affect hormones can cause the line to darken.
- Sun exposure can also increase melanin production, making the line more noticeable.
3. Underlying Health Conditions
- In rare cases, hormonal imbalances or medical conditions might cause the line to appear. If you’re concerned, talk to your doctor.
Is the Linea Nigra Harmful?
No, the linea nigra is not harmful. It’s a natural change in the skin and doesn’t require treatment. For most people, it fades on its own over time.
Can You Make the Linea Nigra Go Away?
While you can’t completely prevent the linea nigra, there are ways to make it less noticeable:
1. Give It Time
- After pregnancy or when hormone levels return to normal, the line usually fades on its own.
2. Use Sunscreen
- Sun exposure can darken the line. Applying sunscreen to your abdomen when you’re outside can help prevent it from getting darker.
3. Cover It with Makeup
- If the line bothers you, you can use makeup to temporarily cover it. Avoid using skin bleach, as it can irritate your skin and cause side effects.
When to See a Doctor
The linea nigra is usually harmless, but if you’re worried about hormonal imbalances or other health issues, talk to your doctor. They can check for underlying conditions and provide guidance.
