Diastasis (physiology)

Diastasis in physiology refers to the separation of parts of the body that are normally joined together. This term is most commonly used in the context of diastasis recti, a condition where the rectus abdominis muscles separate along the midline of the abdomen. Diastasis can also occur in other parts of the body, such as the pubic symphysis.

Diastasis Recti

Diastasis recti is a condition characterized by the separation of the rectus abdominis muscles, which are the two large vertical muscles that run down the front of the abdomen. This condition is most commonly seen in pregnant and postpartum women, but it can also occur in newborns and men. The separation occurs along the linea alba, a fibrous structure that runs down the midline of the abdomen.

Causes

The primary cause of diastasis recti is increased internal abdominal pressure. In pregnancy, the growing uterus stretches the abdominal muscles, which can lead to separation. Other causes include:

• Obesity
• Heavy lifting
• Chronic coughing
• Multiple pregnancies

Symptoms

Symptoms of diastasis recti include:

• A visible bulge or "pooch" in the abdomen
• Lower back pain
• Poor posture
• Difficulty lifting objects
• Constipation

Diagnosis

Diastasis recti is typically diagnosed through a physical examination. A healthcare provider may ask the patient to lie on their back and perform a small crunch. The provider will then feel for a gap between the rectus abdominis muscles.

Treatment

Treatment options for diastasis recti include:

• Physical therapy
• Exercise programs focused on strengthening the core muscles
• Surgery in severe cases

Diastasis of the Pubic Symphysis

Diastasis of the pubic symphysis is a condition where the pubic bones separate at the front of the pelvis. This condition can occur during childbirth or as a result of trauma.

Causes

The primary causes of diastasis of the pubic symphysis include:

• Childbirth
• Pelvic trauma
• High-impact sports

Symptoms

Symptoms of diastasis of the pubic symphysis include:

• Pain in the pelvic region
• Difficulty walking
• Swelling and bruising

Diagnosis

Diagnosis is typically made through a combination of physical examination and imaging studies such as X-ray or MRI.

Treatment

Treatment options include:

• Rest
• Physical therapy
• Pain management
• Surgery in severe cases
