Linea Alba

Linea alba is a Latin term that translates to “white line,” and it refers to a narrow band of tissue that runs vertically along the midline of the abdomen. The linea alba is made up of tough fibrous tissue that connects the abdominal muscles to one another. It is typically about 1-2 cm wide and runs from the bottom of the sternum to the pubic bone.

Diseases or conditions associated with the linea alba include diastasis recti, hernias, and abdominal aortic aneurysms. Diastasis recti is a condition where the abdominal muscles separate, causing a bulge in the middle of the abdomen. Hernias can also occur in the linea alba, where a portion of the intestine protrudes through a weak spot in the abdominal wall. Abdominal aortic aneurysms are a dangerous condition where the aorta, the body’s largest artery, becomes weakened and bulges out, potentially causing life-threatening complications.


There are no specific causes of linea alba as it is a normal anatomical structure in the body. However, in rare cases, it can be a sign of an underlying medical condition. Some of these conditions include:

  1. Diastasis recti: This is a separation of the abdominal muscles that can cause the linea alba to become more prominent.
  2. Hernias: Hernias occur when an organ or tissue pushes through a weak spot in the abdominal wall, causing the linea alba to bulge.
  3. Tumors: In rare cases, tumors can form along the linea alba, causing a visible lump or swelling.
  4. Inflammatory bowel disease: Chronic inflammation of the digestive tract can cause changes in the appearance of the linea alba.
  5. Lichen planus: This is a skin condition that can cause white patches to form on the skin, including the linea alba.

Overall, the linea alba is a normal anatomical feature of the body and is not typically a cause for concern. However, if it becomes more prominent or is accompanied by other symptoms, it is important to seek medical attention to rule out any underlying medical conditions.


While linea alba is a normal and essential part of the abdominal anatomy, it can sometimes become more visible or prominent due to certain factors. For example, pregnancy, weight gain, or abdominal muscle stretching exercises can cause the linea alba to widen or separate, resulting in a condition called diastasis recti. This can lead to a visible bulge in the midline of the abdomen, especially when the abdominal muscles are contracted.

Other than the visible bulge, there are no other symptoms associated with linea alba or diastasis recti. However, if the condition is severe, it may cause back pain, poor posture, or difficulty with activities that require abdominal strength.

In summary, linea alba is not a disease, but a normal part of the abdominal anatomy. If it becomes more visible or prominent, it may indicate diastasis recti, which can lead to a visible bulge and potential complications.


It is a thin fibrous band that runs vertically along the midline of the abdomen, from the xiphoid process of the sternum to the pubic symphysis. It separates the left and right rectus abdominis muscles, which are the paired muscles that form the “six-pack” in well-toned individuals. The linea alba is not a diagnostic test or a marker for any particular disease, but it can be affected by certain conditions that alter the shape or size of the abdominal wall, such as pregnancy, obesity, hernias, or tumors. The presence of a palpable or visible mass or bulge in the abdominal area, or a change in the shape or symmetry of the linea alba, may indicate the need for further evaluation or imaging tests to determine the underlying cause.
