In the birth industry, Linea Alba is a Latin term meaning “white line.” It refers to a white fibrous band that runs down the center of the abdominal wall. The Linea Alba is formed by the fusion of the two recti sheaths, which are the layers of connective tissue that surround the abdominals.
During pregnancy, the Linea Alba stretches and thins as the abdominal muscles separate to make room for the growing baby. This can cause the linea alba markings to become more visible.
Linea Alba is often used interchangeably with other similar terms, such as ‘Linea Nigra’ and ‘Striae Gravidarum.’ However, Linea Alba specifically refers to the white line on the abdominal wall, while ‘Linea Nigra’ refers to a dark line that can form on the abdomen during pregnancy, and ‘Striae Gravidarum’ simply refers to stretch marks.
Linea Alba is closely related to the term Linea Semilunaris, which refers to the crescent-shaped line that runs along the base of the abdomen. The Linea Semilunaris is formed by the fusion of the two rectus abdominis muscles.
While Linea Alba is most commonly used in the birth industry, the term has been known to be used outside of the birth industry as well. For example, Linea Alba has been used to refer to a white line that forms on the surface of the moon during a lunar eclipse.

The width of linea alba can be an indicator for the risk of hernia. A wide linea alba (>10 mm) is a risk factor for incisional hernia, while a narrow linea alba (<5 mm) is a protective factor against incisional hernia.
There are many ways to measure the width of linea alba. The most common method is to use a caliper to measure the distance between the two recti muscles at the level of the umbilicus. Other methods include ultrasound, MRI, and CT scan.
The width of linea alba may change over time. For example, it may widen with age or after pregnancy. It is affected by natural hormonal changes that occur during pregnancy.
Other Types of Stretch Marks
Some other stretch marks that may develop during pregnancy include:
- Stretch marks on the breasts
- Stretch marks on the buttocks
- Stretch marks on the thighs
- Stretch marks on the stomach
These are normal in most cases, as the skin is stretching to accommodate the growing baby. If you are concerned about the appearance of your stretch marks, remember that most stretch marks will change over time and that it is nothing to be ashamed of.
There are a number of ways to treat and prevent stretch marks, including:
- Moisturizing the skin
- Applying cocoa butter or other topical treatments
- Using compression garments
- Getting laser therapy or other cosmetic treatments
If you are concerned about the appearance of your stretch marks, talk to other mothers or a dermatologist to find alternative lifestyle techniques
