An epigastric hernia, commonly occurring between the xiphoid process and umbilicus, involves the protrusion of extraperitoneal fat through a weakened linea alba, often affecting manual workers aged 30-45. Symptoms can range from asymptomatic to painful attacks during exertion, with treatment options including surgical intervention when necessary. Surgical procedures involve clearing herniated fat, closing the defect, and potentially using mesh reinforcement for larger hernias.
