Abdominal wall laxity refers to weakness, stretching, or separation of the muscles and connective tissues of the abdominal wall, leading to a protruding or sagging abdomen despite weight control or exercise. This condition is commonly seen after pregnancy, significant weight fluctuations, aging, or previous abdominal surgeries. Unlike superficial fat accumulation, abdominal wall laxity involves structural changes that cannot be corrected through diet or exercise alone.

One of the most common contributors to abdominal wall laxity is diastasis recti, a condition where the rectus abdominis muscles separate along the midline due to prolonged stretching. Pregnancy places significant strain on the abdominal wall to accommodate fetal growth, and in many individuals, the muscles do not fully return to their original position postpartum. Repeated pregnancies, multiple births, or large babies further increase the risk. Significant weight gain and subsequent weight loss can similarly overstretch the abdominal tissues, reducing elasticity.

Patients with abdominal wall laxity may notice a persistent abdominal bulge, poor core strength, lower back pain, postural problems, and reduced physical performance. Some experience difficulty engaging core muscles during exercise, while others report functional concerns such as discomfort during prolonged standing or lifting. In severe cases, abdominal wall weakness may coexist with hernias, increasing the risk of complications.

Clinical evaluation includes assessment of muscle separation, skin quality, fat distribution, and any associated hernias or scars from prior surgeries. Functional symptoms are carefully documented, as abdominal wall laxity is not merely a cosmetic concern. The impact on daily activities, posture, and musculoskeletal health is an important part of decision-making.

Management depends on severity and patient goals. Mild laxity may benefit from targeted physiotherapy focused on core strengthening and posture correction. However, moderate to severe abdominal wall laxity often requires surgical intervention to restore muscle integrity and abdominal contour. Surgical correction focuses on tightening the abdominal muscles and reinforcing the abdominal wall, improving both function and appearance.

Post-treatment outcomes typically include improved core stability, reduced back discomfort, enhanced posture, and a flatter, more defined abdominal profile. Addressing abdominal wall laxity helps patients regain confidence, physical comfort, and functional strength, especially after life events such as pregnancy or major weight loss.
