A hernia on a woman typically looks like a soft, rounded bulge that appears where it shouldn’t, most commonly near the belly button, in the groin, or along a surgical scar. The bulge may be as small as a grape or as large as a grapefruit, and it often becomes more visible when you stand up, cough, or strain. In some cases, there’s no visible bulge at all, which makes hernias in women notoriously easy to miss.
Groin Hernias: Inguinal and Femoral
Groin hernias in women come in two forms, and they look slightly different because they push through different spots. An inguinal hernia creates a bulge in the crease where your inner thigh meets your lower abdomen. The bulge sits above the crease of your groin, closer to the midline of your body. On imaging, these hernias average about 3 centimeters across but can range from roughly 1 to 10 centimeters, so a small one may look like a marble-sized lump while a large one creates an obvious swelling you can see through clothing.
Femoral hernias appear slightly lower and more to the outer side of the groin, closer to the top of your thigh. They tend to be a bit smaller, averaging around 2 to 3 centimeters. Femoral hernias are far more common in women than in men, occurring at a ratio of roughly 10 to 1. Because of their position, they can be mistaken for a swollen lymph node. One key difference: a hernia bulge is soft, often disappears when you press on it or lie down, and gets more prominent when you cough. A swollen lymph node feels firm, doesn’t change with position, and won’t pop back in when you push on it.
Umbilical Hernias and the Belly Button
An umbilical hernia shows up as a bulge on or directly around your belly button. Part of the small intestine, along with fat or fluid, pushes through a weak spot in the abdominal wall right at the navel. The result is a soft, squishy lump that can make your belly button look like it’s sticking out or has changed shape. For some women, the bulge is always there. For others, it only appears when there’s pressure on the abdomen, like during a bowel movement, while lifting something heavy, or when laughing hard.
Women who have given birth multiple times have a higher risk of developing umbilical hernias. Pregnancy stretches and weakens the abdominal wall around the navel, and each pregnancy adds to that strain. The hernia may first become noticeable during pregnancy itself or show up months or years later.
Incisional Hernias After Surgery
If you’ve had abdominal surgery, including a cesarean section, hysterectomy, or any procedure that required cutting through the abdominal wall, an incisional hernia can develop along or near the scar. It looks like a bulge or lump rising from the skin at the surgical site. A small incisional hernia measures about 2 inches (5 centimeters) across and may be easy to overlook. A large one, over 4 inches (10 centimeters), creates a more obvious swelling and is more likely to cause pain.
The bulge becomes more noticeable when you stand up or put strain on your abdominal muscles. You might not see anything at all while lying flat, then notice it clearly when you’re standing, constipated and bearing down, or getting up from a chair. The skin over the bulge usually looks normal in color and isn’t tender to touch unless the hernia is becoming trapped.
Occult Hernias: When There’s No Visible Bulge
One reason hernias are underdiagnosed in women is that they don’t always produce a visible lump. These are sometimes called occult, or hidden, hernias. The defect in the muscle wall exists, but it’s deep enough or small enough that nothing bulges outward. Instead, the hernia presses on nearby nerves.
Research from a pelvic physical therapy practice found that out of 35 women with endometriosis screened for occult hernias, 22 tested positive for nerve compression affecting the groin and genital area. Symptoms of an occult hernia can include groin pain, pain during sex, genital pain, pelvic floor pain, a sensation of urinary pressure, increased lower abdominal pain during menstruation, and pain radiating into the leg. Because these symptoms overlap heavily with endometriosis, pelvic floor dysfunction, and other gynecological conditions, occult hernias in women often go unrecognized for years.
If you’re experiencing chronic groin or pelvic pain without a visible bulge, an MRI or ultrasound can detect defects in the muscle wall that aren’t visible from the outside. For groin hernias specifically, ultrasound, MRI, and CT scans are all considered appropriate imaging options.
How to Check Yourself
You can look for a hernia at home by standing in front of a mirror and watching specific areas while you cough or bear down. Focus on your belly button, your groin creases, and any surgical scars on your abdomen. A hernia will appear as a soft bulge that pops out during strain and may flatten or disappear when you relax or lie down. You might also feel pressure, a dull ache, or a pinching sensation when the bulge emerges.
Try checking in different positions. Some hernias are only visible while squatting, bending over, or lifting. If you notice a bulge that comes and goes with activity, that pattern alone is a strong indicator. A lump that stays the same size regardless of position or strain is more likely a cyst or lymph node than a hernia.
What a Hernia Looks Like vs. Other Lumps
In the groin area especially, it can be hard to tell a hernia apart from other types of lumps. Here’s how they compare:
- Hernia: Soft, changes size with coughing or position changes, often disappears when you press on it or lie down.
- Swollen lymph node: Firm, stays the same size regardless of position, doesn’t go back in when pressed, may be tender if caused by infection.
- Cyst: Usually round and well-defined, doesn’t change with coughing or straining, feels like a distinct ball under the skin.
A hernia that goes away when you press on it is generally less urgent than one that stays out. A hernia you can’t push back in may be incarcerated, meaning tissue is trapped in the opening.
Warning Signs That Need Immediate Attention
Most hernias look like skin-colored, painless bulges. When the appearance changes, it can signal that the hernia has become strangulated, meaning the blood supply to the trapped tissue is cut off. The visual warning signs follow a specific pattern: the skin around the bulge first becomes paler than your normal skin tone, then gradually turns darker or reddish. This color change, combined with sudden severe pain, nausea, or vomiting, indicates the tissue is losing blood flow and needs emergency surgical repair.
A hernia that was previously easy to push back in but suddenly won’t flatten, or one that becomes hard and extremely tender, has likely become incarcerated or strangulated. The transition from a harmless-looking soft bulge to a firm, discolored, painful lump can happen within hours.
