Glue therapy is a treatment for varicose veins that involves using a special medical glue to seal off the problematic vein. During the procedure, the doctor inserts a thin tube into the vein and injects the glue, which sticks to the vein walls and seals them shut. This stops the blood flow through the vein.

 Over time, the sealed vein is absorbed by the body and fades away. Glue therapy is a minimally invasive and effective alternative to traditional vein treatments like surgery or laser therapy.
