What causes a hernia in a female after abdominal surgery (lap band removal)? incision is four steri strips long

Strain: Tissue weakness and strain on suture line before scar formation or poor surgical closer, which is very uncommon.

Hernia: I assume you are talking about an abdominal wall hernia and not a hiatal hernia. If you have had surgery, your incisions can develop into incisional hernias. The incision gets weak over time and can allow your intestines to bulge through. Incisional hernias are more likely to happen in people that are overweight. Fixing them is fairly simple and i typically do this laparoscopically.

Many factors: There are many factors that contribute to hernia formation after an operation, including a genetic predisposition, suturing technique, obesity, post-op activity level, immune system suppression, and infection to name a few. Hope you don't get a hernia.
