Often, it's the intestines. This sounds like it would cause noticeable symptoms—and sometimes it does. However, many don't have any hernia symptoms at all, or they simply notice a bump or bulge. Hernias can produce a bulge that is constant or that may come and go, depending on your position or what you’re doing. Hernia surgery may be needed in some cases, but not all. Learn more about treatment decisions are made, the types of hernia that exist, how they are diagnosed, and what you can do to prevent a hernia. 1:57 Click Play to Learn All About Hernias This video has been medically reviewed by Kashif J. Piracha, MD Types of Hernia Most hernias occur in the abdominal area, between your chest and hip bones. Hernias that can be pushed back into place are called reducible hernias. Those that can’t be popped back into position are termed irreducible or incarcerated. If you can feel the hernia on the outside of your body (you might notice a bump), you have an external hernia. Those that can’t be felt are labeled internal hernias. Hernias are further classified by the body region where they occur. ' Inguinal Hernias Inguinal hernias typically occur in the inguinal canals, which are located on either side of the groin. Inguinal hernias are one of the most common types of hernia, affecting 27% of men and 3% of women. Umbilical Hernias Umbilical hernias occur when tissue or parts of the intestine push through a weak area near the navel. They account for 6-14% of adult abdominal hernias, making them the second most common type. Up to 20% of newborns have this hernia. If not closed by age 5, it needs to be closed surgically. Hiatal Hernias Hiatal hernias occur when parts of the stomach or other organs break through an opening in the diaphragm. Hiatal hernias are very common and the overwhelming majority are what’s known as “sliding” hiatal hernias, meaning they can move in and out of place. Femoral Hernias Femoral hernias are found in the lower groin area, near the upper thigh. Women, because of their wider pelvises, are four times more likely than men to develop femoral hernias. Incisional Hernias The cutting (incision) and sewing of surgery can weaken a muscle wall, making it more likely an incisional hernia will develop. Roughly 15% of people will develop an incisional hernia after surgery involving the abdominal wall. Hernia Symptoms Laura Porter / Verywell Most hernias can be felt. You might notice a bump or bulge (it may be hard or soft) in an area of your body. Not all hernias produce discomfort, but when they do you might experience: BurningPullingPainPressureSwellingDigestive issues like heartburn or gastroesophageal reflux disease (GERD) The discomfort may be more intense when you strain (for example, while having a bowel movement or lifting a heavy object) or tighten your abdominal muscles (when you’re coughing, sneezing or exercising, for instance). Complications Get immediate medical attention if you have: Pain around the hernia that’s sudden or severeNausea and vomiting along with the pain These could be signs that an organ or tissue is dangerously stuck within the torn area or that its blood supply is being cut off (called a strangulated hernia). This is a medical emergency. What Causes a Hernia? Hernias occur when pressure is put on a weak or injured muscle. Hernias can happen to anyone—male or female, young or old. Sometimes you’re born with a weakening in muscle walls that can make you prone to a hernia, and other times it develops over time. Some risk factors for hernia development include: Sex: Males have hernias about twice as often as females. When a fetus' testicles descend from the abdomen, the opening doesn’t always close properly. That increases hernia risk. Having excess weight or obesity: Extra weight increases pressure on muscles and organs, weakening the structures that hold things in place. Pregnancy, especially multiple pregnancies: As a fetus grows, so, too, does the strain on your abdominal wall. Age: Muscles become weaker as you age. Prior surgery: Surgery in the abdominal or groin area can weaken the muscles. Performing activities that can strain abdominal muscles: This includes heavy lifting. Persistent coughing: Coughing places pressure on the chest and abdomen. Tobacco use: This can lead to chronic coughing. Family history of hernias: Males with a family history of inguinal hernias are eight times more likely to develop one than other males. Constipation: This can result in straining during a bowel movement, placing pressure on the abdomen. Diagnosis To diagnose a hernia, your healthcare provider will perform a physical exam, feeling for a hernia while you sit, stand or even cough. They may also order imaging tests like an ultrasound or computed tomography (CT) scan. Your provider may also perform an endoscopy, which uses a flexible scope equipped with a light and camera to examine the inside of your esophagus and your stomach. What Can Be Mistaken for a Hernia? There are times when someone is diagnosed with a hernia when they really have something else. Some conditions that can be mistaken for a hernia include: Pubic and inguinal venous collateralsAcute vasitis (inflammation of the vas deferens, which is a duct that carries sperm from the testicle to the urethra)Spermatic cord lipomas (fatty tumors on the cord-like structure formed by the vas deferens and the tissue around it)Spermatic cord cancerAdhesionsAppendicitisDiverticulitis (inflammation of the colon)Hip problemsInflammatory bowel diseaseLumbar disc diseasesProstatitis (prostate inflammation)Urinary tract infection Likewise, as your doctor evaluates you, they may consider and work to rule out these issues. Hernia Treatment How your hernia is treated depends on a number of factors, including where the hernia is located, its size, whether it’s growing and if it’s causing you discomfort. Even anatomy plays a role. Inguinal hernias in those born female may be treated more aggressively than in those born male. Surgery In general, for hernias that are small and asymptomatic, your doctor may advise simply watching the hernia. For hernias that are large, causing pain or impacting your quality of life, surgery may be recommended. Types of hernia surgery include open surgery, laparoscopic surgery, and robotic surgery. Open Surgery In open surgery, the surgeon cuts through the body where the hernia is located. The bulging parts are put back into place and the tear is stitched. Instead of sutures, a doctor might use a mesh panel (usually made of plastic or animal tissues) to provide added support. Those who have their inguinal and femoral hernias repaired with a mesh appear to have a reduced risk of hernia recurrence. Laparoscopic Surgery Using small incisions through which surgical tools (usually a flexible tube with a camera and light that guides the surgeon), the organs/tissues are moved back to where they belong and the hole is repaired. This is considered minimally invasive surgery and has a quicker recovery time than open surgery. Robotic-Assisted Surgery Robotic-assisted surgery is similar to laparoscopic surgery, but the surgeon operates the tools from a console. Herniorrhaphy: What to Expect with Hernia Repair Surgery Prevention Other than the umbilical hernias that affect newborns, a hernia will not go away on its own. See your doctor if you notice a bulge. If you have any of the risk factors for a hernia, make sure your doctor is checking for them at your physical exams. To keep hernias at bay, stay on top of your health game: Maintain a healthy weight.Stay hydrated and eat a diet rich in fruits, whole grains and vegetables to avoid constipation.Don’t lift more than you’re able.Don’t smoke. A Word From Verywell Finding a bump or bulge on your body can be scary, and your first step is to get it checked out by a doctor. But if you’re diagnosed with a hernia, rest assured that you’re not alone. Hernias are quite common, and the surgeries that are often used to treat them are some of the most frequently performed surgeries in the U.S. More than 20 million hernias are repaired every year, worldwide, with 700,000 of those in the U.S. alone. While there are risks with any surgery, hernia surgery is considered safe and effective. Recovery will depend on your overall health and the type of surgery performed, but many people are back to their regular routines in just a couple of weeks. 18 Sources Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.
