A hernia is a condition in which an internal organ or tissue protrudes through a weak spot in the muscle or tissue that normally holds it in place. Hernias can occur anywhere in the body, but they are most common in the abdomen or groin region.

Hernias can occur after weight loss surgery. These are specific types of hernias that occur uncommonly but can cause symptoms such as reflux or pain.

Different types of hernias

There are many different types of hernias, but the most common types that occur after weight loss surgery are:
  • Hiatal hernia: This type of hernia occurs when the upper part of the stomach pushes up through the diaphragm and into the chest. This causes reflux and/or heartburn

  • Incisional hernia: This type of hernia occurs through an incision made during surgery. Although this can occur with keyhole surgery it is very uncommon.

  • Internal abdominal hernia: This type of hernia occurs inside the abdomen, when a loop of intestine pushes through into a space it isn’t supposed to be. This can occur in gastric bypass surgery but again is uncommon.

Symptoms of hernias

The symptoms of a hernia can vary depending on the type of hernia and its location. However, some common symptoms of hernias include:

  • A bulge in the abdomen or groin
  • Pain or discomfort in the area of the hernia
  • Abdominal pain and/or vomiting
  • Difficulty swallowing or reflux (in the case of a hiatal hernia)

Diagnosis of hernias

If you are experiencing any of the symptoms of a hernia, your doctor will likely take a medical history as well as perform a physical examination. They may also order an ultrasound or CT scan to confirm the diagnosis.

Treatment of hernias

The main treatment for a hernia is surgery to repair the weakened muscle or tissue. This surgery is usually performed laparoscopically (using keyhole surgery).

Recovery after hernia repair surgery

Most people recover from hernia repair surgery quickly as it is performed laparoscopically. You will be able to go home from the hospital generally after a short hospital stay. However in some occasions depending on specific circumstance your hospital stay will be further determined by your doctor.
