You can absolutely lose your belly button, and it happens to more people than you might expect. Surgery is the most common reason, whether it’s a planned cosmetic procedure like a tummy tuck or a medically necessary operation for a birth defect or abdominal emergency. Some people are born with conditions that displace or prevent the navel from forming normally in the first place. The belly button occupies a surprisingly meaningful spot in how people see their own bodies, and losing it, or never having had one, has prompted surgeons to develop dozens of techniques for building one from scratch.
What the Belly Button Actually Is
The belly button is a scar. It marks the spot where the umbilical cord connected you to the placenta before birth. That connection forms remarkably early: the umbilicus appears around the fourth week of fetal development, when the flat embryonic plate begins to fold inward. At that stage, the site is a ring that houses umbilical blood vessels, a loop of developing intestine, and several temporary structures that will eventually disappear. By birth, the cord has narrowed to three blood vessels embedded in a jellylike cushion, and once it is clamped and cut, the stump dries, falls off, and leaves behind the familiar indent or protrusion we call a belly button.1Frontiers of Medicine. Anatomy and embryology of umbilicus in newborns: a review and clinical correlations
Because the belly button is just a scar in the skin and underlying fascia, it has no ongoing biological function after birth. There is no organ underneath it, no open channel to the interior of your body. That is partly why it can be lost or altered without any physiological consequence. But its visual significance is another story entirely.
Congenital Conditions That Prevent or Displace the Navel
Some babies are born with the belly button missing, severely misplaced, or buried in scar tissue from conditions that required emergency repair at birth. Two of the best-known examples are omphalocele and gastroschisis, both of which involve abdominal organs developing partly outside the body wall. Surgical closure of these defects saves the child’s life, but it reshapes the abdominal surface in ways that can erase the normal navel anatomy. In one study comparing long-term outcomes for children who had these repairs, about 81% of gastroschisis patients said they were satisfied with the cosmetic appearance of their abdominal scar, though they were more likely to have bowel complications and irregular stools than children treated for omphalocele.2PubMed Central.

Bladder exstrophy is another congenital condition that routinely affects the belly button. In these cases, the bladder forms on the outside of the abdomen, and the umbilicus ends up displaced downward, attached to the upper edge of the exposed bladder. For decades, surgeons simply removed the navel during the repair without a second thought. Many patients who grew up without a belly button later reported distress about the absence, describing it as a visible deformity they felt self-conscious about.3Journal of Urology. Umbilical Reconstruction in Patients With Exstrophy: The Kangaroo Pouch Technique That feedback eventually shifted surgical practice toward preserving and repositioning the umbilicus whenever possible during bladder closure.4PubMed. Reconstruction of umbilicus during functional closure of bladder exstrophy
Losing Your Belly Button to Surgery
The single most common reason adults lose their belly button is abdominal surgery, and abdominoplasty, commonly called a tummy tuck, leads the list. During a standard tummy tuck, the surgeon removes a large section of excess skin and fat from the lower abdomen, then pulls the remaining skin downward to create a flatter profile. Because the navel is attached to the underlying muscle layer by a stalk, it does not move with the skin. The surgeon cuts a new opening in the repositioned skin and stitches the navel into its new spot. This step is called umbilical transposition, and if it goes well, the belly button looks natural in its new location.5PubMed. The two-dermal-flap umbilical transposition: a natural and aesthetic umbilicus after abdominoplasty
When things go less smoothly, the relocated belly button can flatten out, shift off center, or heal with visible scarring that makes it look artificial. In more drastic abdominal surgeries, such as large hernia repairs, tumor excisions, or emergency operations for trauma, the navel is sometimes sacrificed entirely because preserving it would compromise the surgical outcome. Surgeons treating bladder exstrophy reported that in roughly 96% of cases the early results of umbilicoplasty looked excellent or satisfactory, but a small percentage of patients needed revision surgery within a year or two because the reconstructed navel had gone flat and lost depth.6PubMed. Results of umbilicoplasty for bladder exstrophy That pattern of gradual flattening over time is a recurring challenge in navel reconstruction regardless of the original cause.
Other abdominal procedures that can erase or damage the navel include ostomy surgeries, where an opening for waste is created through the abdominal wall, and surgeries for conditions like necrotizing fasciitis, where large areas of skin and tissue must be removed to control infection. In each case, the belly button is not the surgical priority; keeping the patient alive and functional is. The navel gets sacrificed as collateral.
Medical Conditions That Can Destroy the Navel
It is not always a surgeon’s scalpel that takes the belly button. Certain diseases can damage or distort the navel on their own. Umbilical hernias, where a loop of intestine or fatty tissue pushes through the abdominal wall at the navel site, can stretch the belly button beyond recognition if they become large or require surgical mesh repair. The mesh flattens the area and often eliminates the characteristic dimple.
Cutaneous endometriosis is a less well-known culprit. This condition involves endometrial tissue, the same tissue that lines the uterus, growing in the skin, and the belly button is one of its favored locations. In a review of 33 women with cutaneous endometriosis, nearly all had a history of prior abdominal surgery, and the most common symptom was an abdominal mass at the navel, reported in 96% of cases. About half also experienced cyclical pain at the site. Surgical removal was necessary for the vast majority, and roughly a quarter of those patients needed a prosthetic mesh to close the resulting defect.7European Journal of Obstetrics & Gynecology and Reproductive Biology. Cutaneous endometriosis: Presentation of 33 cases and literature review After that kind of excision, the belly button is often gone or severely altered.
Tumors that seed at the navel, sometimes called Sister Mary Joseph nodules, are another possibility. These are metastatic deposits from cancers elsewhere in the abdomen or pelvis. They are uncommon but clinically significant because they often signal advanced disease. Treating the nodule typically involves removing tissue at the navel site, which again can leave the area flat and featureless.
Can You Get a New Belly Button?
Yes, and surgeons have been surprisingly creative about it. A literature review found sixty different techniques for reconstructing a missing umbilicus described across 77 published papers. The most common approaches involve local skin flaps, where nearby tissue is folded and sutured into a small depression, and purse-string sutures, which cinch a circle of skin inward to mimic the natural dimple.8Aesthetic Plastic Surgery. Umbilical Reconstruction Techniques: A Literature Review The sheer number of techniques reflects the fact that no single method works perfectly for every patient. Fat distribution, skin quality, scar tissue from prior operations, and the patient’s body shape all influence which approach gives the most natural-looking result.
The term for building a belly button from nothing is umbiliconeoplasty, which specifically refers to creating a navel where none exists, whether the absence is congenital or the result of surgery or injury.9PubMed Central. Umbilical reconstruction: different techniques, a single aim This is distinct from umbilicoplasty, which reshapes or repositions an existing navel. Both procedures are outpatient in most cases and carry low complication rates, though the long-term challenge of the reconstructed navel flattening out remains real. Patients who want the deepest, most natural-looking result sometimes need a revision procedure a year or more after the initial surgery.
Reconstruction is not only a cosmetic luxury. For children who grew up without a belly button because of congenital repairs, and for adults who lost theirs to emergency surgery, the procedure addresses something that feels psychologically important. You do not realize how much the belly button registers as a visual anchor of the human torso until it is missing.
Why a Missing Belly Button Bothers People
At first glance, caring about a small scar on your midsection might seem trivial. The belly button does nothing after birth. But people who lack one consistently describe it as a source of self-consciousness, especially in situations involving exposed skin: swimming, changing in locker rooms, intimacy. The distress is real enough that researchers recently developed a dedicated measurement tool, the BODY-Q Belly Button Scale, specifically to capture how satisfied or dissatisfied people feel about their navel’s appearance. In its validation study involving 372 participants, the scale was refined to six items that reliably measured how people perceived the look and shape of their belly button.10Aesthetic Surgery Journal. The BODY-Q Belly Button Scale: A Development and Validation Study
The fact that a validated clinical instrument now exists for belly button satisfaction speaks to how seriously the field takes this concern. Surgeons treating bladder exstrophy noticed the same thing decades ago: patients who had their navels removed during childhood repair frequently raised the issue during follow-up visits, calling the absence a deformity.3Journal of Urology. Umbilical Reconstruction in Patients With Exstrophy: The Kangaroo Pouch Technique That patient feedback was a major driver behind the shift toward navel-preserving surgical techniques and the development of reconstruction options.
Children may feel the impact more acutely than adults. A child born with gastroschisis or omphalocele who grows up with an unusual-looking or absent belly button navigates questions from peers throughout childhood and adolescence. Adults who lose a belly button to a tummy tuck gone wrong or to emergency surgery at least remember having one, which frames the loss differently. For children, the belly button they see on everyone else is something they never had.
What Makes a Belly Button Look “Normal”
There is no single correct belly button. They come in a wide range of shapes, from deep vertical slits to horizontal creases to outward protrusions (the so-called “outie”). Position varies too, though most navels sit roughly at the level of the top of the hip bones, in the midline of the abdomen. What tends to look “off” to the human eye is not a specific shape but a flat, featureless patch of skin where some kind of indent is expected. That is the hallmark of a missing or poorly reconstructed navel.
Plastic surgeons aiming for natural results typically try to create a small, slightly hooded depression with a bit of shadow at its center. The shadow turns out to matter a great deal; a belly button that sits flush with the surrounding skin reads as artificial even if it is technically in the right spot. Techniques that anchor the base of the new navel to the deeper abdominal fascia tend to maintain their depth better over time, but tissue remodeling and weight fluctuations can still flatten things out. This is why the sixty-plus published techniques exist: each one tries to solve the depth-retention problem in a slightly different way.8Aesthetic Plastic Surgery. Umbilical Reconstruction Techniques: A Literature Review
Belly Buttons and Weight Loss Surgery
Massive weight loss, whether through bariatric surgery or lifestyle changes, frequently distorts the belly button. As the abdominal skin stretches during obesity and then deflates during weight loss, the navel can migrate downward, stretch into an unrecognizable slit, or become buried in redundant skin folds. The belly button is technically still there, but functionally it has been lost in the sense that it no longer looks or behaves like one.
Body contouring surgery after major weight loss often includes a panniculectomy or abdominoplasty to remove excess skin. During these procedures, the navel faces the same transposition challenge described earlier. Surgeons detach it from the surrounding skin, excise the excess tissue, and reposition the navel through a new hole in the tightened skin. The results depend heavily on how much skin needs to be removed and how much the abdominal wall has been weakened. Patients who have lost a hundred pounds or more present a very different surgical canvas than someone seeking a standard tummy tuck after pregnancy.
Do All Mammals Have Belly Buttons?
Every placental mammal has an umbilical scar. Dogs, cats, horses, dolphins, whales, and primates all develop via a placenta and umbilical cord, and all of them carry some trace of that connection after birth. In most animals, the scar heals flat and is quickly hidden by fur or skin texture, which is why you have probably never noticed your dog’s belly button. It is there, usually a small, thin line or slight irregularity on the abdomen, but it is nothing like the deep dimple that humans carry.
The human belly button is unusually prominent for a mammal. Our relative hairlessness makes it conspicuous, and the way human skin heals at the umbilical site tends to produce a deeper, more defined scar than what forms on most other species. Marsupials and egg-laying mammals do not have belly buttons at all, since they either develop in a pouch or in an egg rather than being nourished through a placental cord. So while the belly button is essentially universal among the mammals you are most likely to encounter, it is not a universal feature of all mammals.
Piercing, Infection, and Accidental Damage
Belly button piercings are one of the most common body piercings, and they carry a higher rejection and infection rate than ear piercings because of the navel’s location. The area folds, stretches, and rubs against waistbands constantly. A badly infected navel piercing can damage the surrounding tissue enough to leave permanent scarring that distorts the belly button’s shape. In extreme cases, surgical debridement of infected tissue can leave the area looking significantly different from its original form.
Burns, trauma from car accidents, and dog bites to the abdomen can also destroy the navel. These are not common scenarios, but they illustrate the broader point: the belly button is just skin and scar tissue. Anything that damages skin in that area can erase it. Unlike an organ, there is nothing underneath to regenerate; once the surface anatomy is disrupted, the belly button is gone unless someone reconstructs it.
The good news, if you can call it that, is that losing a belly button carries zero health consequences. It creates no vulnerability, no opening to infection, no metabolic problem. The issue is entirely one of appearance and identity. For some people that matters enormously, and for others it barely registers. Whether reconstruction makes sense depends entirely on how much the absence bothers you, and surgeons have enough tools in their kit to offer a credible option for almost anyone who wants one.
