Rectus diastasis can absolutely affect men, and it’s more common than many people realize. According to recently published research, roughly 30% of American men have some degree of rectus diastasis. The condition occurs even more frequently in men with other abdominal wall issues, such as abdominal wall hernias, highlighting a strong association between muscle separation and broader abdominal wall weakness.
Dr. Gregory Dumanian, Chief of Plastic Surgery at Northwestern and a board-certified general and plastic surgeon, is internationally known for his expertise in treating rectus diastasis with the most advanced techniques. Here’s what men need to know about the condition.
Why Rectus Diastasis Develops in Men
Rectus diastasis occurs when the connective tissue between the left and right abdominal muscles stretches and thins, allowing the muscles to separate. The thin line of fascia between the muscles is called the linea alba (white line). In young individuals, it is the width of one’s fifth finger. While often discussed in relation to pregnancy, research and clinical experience show that men are also frequently affected.
In men, rectus diastasis often develops due to increased intra-abdominal pressure over time. Common contributors include weight gain, heavy lifting, chronic straining, previous abdominal surgery, and underlying connective tissue disease. Aging can also play a role, as abdominal tissues naturally lose strength and elasticity over time. The linea alba, which generally is less than 2 cm in men, can widen to even 8-10 cm in the most severe cases.
Signs of Rectus Diastasis in Men
Men may notice a bulge down the center of the abdomen, especially when sitting up or tightening their core. Others experience lower back discomfort, reduced core strength, or a feeling that their abdomen no longer feels stable. Because these symptoms can overlap or be mistaken for hernias, rectus diastasis is sometimes overlooked or misunderstood.
How Rectus Diastasis Differs From a Hernia
Rectus diastasis isn’t a true hernia, as there’s no hole in the abdominal wall. Instead, the connective tissue stretches and thins, allowing the muscles to drift apart. That said, rectus diastasis and hernias often coexist. When both are present, they can worsen each other and contribute to functional problems rather than just cosmetic concerns. The most common association is an umbilical hernia with rectus diastasis.
This overlap explains why rectus diastasis is so common in men with other abdominal wall conditions. Appropriately addressing muscle separation requires careful evaluation and a deep understanding of abdominal wall anatomy.
When Treatment Becomes Part of the Conversation
Most cases of rectus diastasis do not need surgical treatment. Mild separation without symptoms may be managed conservatively with weight loss. However, more severe cases can affect posture, core strength, and daily life. Older textbooks state that male pattern rectus diastasis is not repairable with the standard sutures that are used for female pattern rectus diastasis. Dr. Dumanian uses advanced approaches, including mesh-supported abdominal wall repair. He’s the inventor of DuraMesh™, the first new surgical suture in 40 years. DuraMesh™ is used now widely around the world to provide a lasting repair of rectus diastasis. The extra skin is that is created by tightening the stomach muscles is removed as a vertical abdominoplasty. The vertical scar is typically hidden by abdominal skin, and the umbilicus is often recreated at the same time.
Rectus Diastasis Evaluation in Chicago
Rectus diastasis in men is real, common, and often underdiagnosed. A thorough evaluation with Dr. Dumanian can clarify whether your symptoms are coming from muscle separation, an associated hernia, or both.
