HERNIA Facts
Reviewed By: Dr. Michael Sawyer
What is a hernia?
A hernia is a defect / hole that occurs over time when fatty tissue or an organ protrudes through the opening that normally contains it. Scroll to learn about the various types and locations of hernias:
Occurs in between chest cavity and abdomen.
Occurs between the sternum and belly button.
Occurs near the belly button.
The location varies as it occurs at the site of a previous surgical cut.
Commonly referred to as a groin hernia and can occur on the right side or left side or both sides.
Appears in the upper thigh or groin area.
Hernia comes back in the same location.
General term used to describe a hernia occurring on the front of the abdomen.
Also referred to as a lateral hernia, occurs near the oblique muscles.
Where the tissue or intestine becomes trapped in the hernia sac and can’t be moved back into place.
When the blood supply is cut off from an incarcerated hernia. This is a medical emergency requiring immediate attention.
What causes a hernia?
In the simplest terms, hernias occur from a combination of internal pressure (like from straining) and weakness/opening in the muscle or fascia of the abdomen.
Hernias are often complicated by a variety of factors which may include any combination of the following:
- Smoking
- Previous surgery
- Diabetes
- Immune response
- Obesity
- Strenuous exercise such as lifting too heavy
- Constipation
- Age
- Weight
- Genetics
- Congenital – occurs at birth

Hernia Symptoms
Am I at risk for a hernia?
Males and females are both at risk for developing a hernia, anatomical differences play a role in how likely you are to develop a hernia.
Due to the extra tissue and space around the male reproductive organs, there's more area for a hernia to occur. As a result, approximately 1 in 4 (or 25%) of males are at risk for developing an inguinal hernia.1
Due to the shape of the female’s pelvis and the deeper location of the reproductive organs, women are more likely to present without a visible bulge. Females are more at risk for umbilical and incisional hernias due to the abdominal wall stretching during pregnancy.2
What can be mistaken for a hernia?
Statistics estimate that 15 out every 1000 people in the US will be diagnosed with a hernia.3 While relatively common, and over 1 million are repaired each year4, there remains a chance a healthcare provider may fail to diagnosis the hernia as the following conditions may mimic the symptoms:
- GERD – gastroesophageal reflux disease
- Diastasis recti – separation of abdominal muscles, and in some cases can be repaired without surgery
- Athletic pubalgia – also known as a sports hernia
- In women pelvic pain may be caused by endometriosis, ovarian cysts, or fibroids

Diagnosing a Hernia
Hernias can only be diagnosed by a licensed health care provider during a visual inspection and a physical exam. Males are probably familiar with the phrase “turn and cough.”
Hernia diagnosis is then confirmed by a provider-ordered imaging diagnostic test such as an ultrasound, CT scan, or MRI.
Can a hernia be diagnosed via telehealth? Thanks to recent technological enhancements, it is possible.
