Certain people are born with a congenital defect — one existing from birth — that causes their abdominal wall to be abnormally thin. They are at a greater risk for developing a ventral hernia. Other risk factors for a ventral hernia include:

• pregnancy
• obesity
• history of previous hernias
• history of abdominal surgeries
• injuries to your bowel area
• family history of hernias
• frequently lifting or pushing heavy objects

According to UCSF, incisional hernias may occur in up to 30 percent of those who’ve had an abdominal surgery. Most occur at the site of a surgical scar. The scar tissue weakens or thins, allowing a bulge to form in the abdomen. This bulge is tissue or organs pushing against the abdominal wall.

Ventral hernias can produce an array of symptoms. Symptoms may take weeks or months to appear.

You may feel absolutely no symptoms. Or you could experience discomfort or severe pain in the area of your hernia, which might grow worse when you try to stand or lift heavy objects. You may see or feel a bulging or growth in the area that feels tender to the touch.

If you experience any of the following symptoms, make sure to consult a doctor right away:

• mild discomfort in your abdominal area
• pain in your abdomen
• outward bulging of skin or tissues in your abdominal area
• nausea
• vomiting

For a complete diagnosis, a doctor will ask you about your symptoms and perform a physical exam. They may need to order imaging tests to look inside your body for signs of a ventral hernia. These may include:

• abdominal ultrasound
• abdominal CT scan
• abdominal MRI scan

Ventral hernias require surgical correction. If left untreated, they continue to grow slowly until they are able to cause serious complications.

Untreated hernias can grow into enlarged ventral hernias that become progressively more difficult to fix. Swelling can lead to trapping of hernia contents, a process called incarceration. This in turn can lead to reduced or no blood supply to the tissues involved, which is referred to as strangulation.

Options for surgical treatment include:

• Mesh placement surgery: A surgeon pushes tissue back into place and then sews in a mesh, which serves as a reinforcing patch, to keep it in place. This is considered safe and reliable, and mesh placement has been shown to reduce risk of hernia recurrence.
• Laparoscopic repair: A surgeon makes multiple small openings and fixes your hernia using guidance with a small camera inside your body to direct the surgery. A mesh may or may not be used.
• Open surgery (nonlaparoscopic): A surgeon makes an incision adjacent to your hernia, pushes the tissues back into place, and then sews the area shut. A mesh may or may not be used.

Benefits of laparoscopic removal include the following:

• much smaller cut site, which lowers chance of infection
• reduced postoperative pain
• reduced hospital stay — generally able to leave day of or day after procedure
• absence of a large scar
• faster overall recovery time

These are a few concerns about open surgery:

• longer stay in the hospital after surgery
• greater amount of pain
• medium to large scar
