An abdominal binder is a wide elastic band or garment that provides support to the abdomen and lower back. It is commonly used post-surgery, after childbirth, or for individuals with abdominal conditions to help stabilize the core, reduce swelling, and promote healing. Abdominal binders come in various sizes and materials, offering adjustable compression for comfort and effectiveness. They can also help improve posture and alleviate discomfort during recovery.
