The Navel: A Small Spot in the Middle of the Abdomen, With Anatomy Worth Knowing

People rarely think about that small spot in the middle of their abdomen — until it causes pain, itching, irritation, or some unusual change catches their attention.

Yet this simple spot is far more than a leftover mark from the umbilical cord. Behind it lie layers of the abdominal wall, and it connects to anatomical structures that represent important remnants from fetal life.

It's the navel.

So what's actually behind it? Is there an open channel leading into the abdomen? Does it still serve any function after birth? How should it be cleaned? And when is pain, redness, or discharge minor, versus something worth seeing a doctor about?

These questions sound simple, but they help explain a part of the body most people overlook.

First: What Is the Navel, Really?

The navel is a scar and anatomical region on the anterior abdominal wall resulting from the site where the umbilical cord attached during fetal life.

Two things need to be distinguished here:

• The umbilical cord in the fetus: a real structure that typically contains two umbilical arteries and one umbilical vein, surrounded by a gel-like tissue known as Wharton's jelly[1].
• The navel in an adult after birth: it is not a continuation of the umbilical cord into the body, and it is not an open tube leading directly to the bladder, liver, or intestines. It's the region where the fetal attachment site healed, its structure transforming into tissue, scar, and fibrous ligaments connected to fetal remnants[2].

This is why reaching the bottom of the navel while cleaning doesn't mean reaching into the abdomen or touching an internal organ.

The navel can be deep, shallow, or shaped differently from person to person, and this variation is normal in many cases. An anatomical study on 57 adult cadavers found that the umbilical ring itself could be round or oval (59% of cases), collapsed or slit-like (21.4%), or fully covered by a band connecting the round ligament of the liver to the umbilical ligaments (19.6%), with other variations in its relationship to the surrounding ligaments[3]. (These percentages reflect a limited sample of 57 cadavers in a single anatomical study, and aren't necessarily a precise reflection of prevalence across the general population.)

What's Behind the Navel?

Looking at the inner surface of the abdominal wall, several important structures are connected to the navel region.

Among the most important are three fibrous fetal remnants[4]:

1. The Median Umbilical Ligament

This ligament is a remnant of the urachus, a fetal structure once connected to the bladder.

After fetal life ends, the urachus closes off and becomes a fibrous cord known as the median umbilical ligament, extending between the navel region and the top of the bladder.

This doesn't mean there's an open channel between the navel and the bladder in a healthy adult.

Under normal conditions, this path is closed and fibrous.

2. The Medial Umbilical Ligaments

On either side of the median umbilical ligament are two ligaments known as the medial umbilical ligaments.

These are remnants of the two umbilical arteries that were once part of fetal circulation, carrying blood from the fetus toward the placenta.

After birth, their distal portions close off and become fibrous ligaments, while other segments of the arteries remain part of the normal pelvic circulation.

3. The Round Ligament of the Liver

There's also the round ligament of the liver (ligamentum teres hepatis), a remnant of the left umbilical vein.

It extends from the navel region within the free edge of the falciform ligament of the liver toward the liver itself. The same anatomical study found that this ligament often ends by splitting into several branches in the area above the umbilical ring, some of which cross the ring itself[3].

So when we talk about the navel "extending inward," the more scientifically accurate picture isn't a single open tube starting at the navel and ending at an internal organ.

Rather, there are fibrous fetal remnants and anatomical pathways connected to the abdominal wall and the navel[4].

Does the Navel Serve a Function After Birth?

In an adult, the navel doesn't perform an active physiological function like the one the umbilical cord served during fetal life.

During pregnancy, the umbilical cord was critically important — it represented the exchange route between the fetus and the placenta, typically containing two umbilical arteries and one umbilical vein. At full term, its average length is around 50–60 centimeters, with natural variation between cases[2].

After birth, this role ends.

In adults, though, the region retains anatomical and medical importance, even though it no longer serves fetal circulation.

The navel region is also an important anatomical landmark for surgeons, and it's among the landmarks visible when looking at the inner surface of the abdominal wall during laparoscopic surgery[1].

Is the Navel an Open Channel Into the Abdomen?

This is one of the ideas most worth correcting.

No.

A normal adult navel is not an open door into the abdominal cavity[1][2].

The bottom of the navel may appear deep, and touching it may feel like reaching a far-off place, but that doesn't mean there's an open channel to the bladder, liver, or intestines.

There's an important difference between:

The external depth of the navel

and

The existence of an open anatomical connection to an internal organ.

Under normal conditions, this open connection doesn't exist.

That said, rare pathological cases exist where fetal remnants persist or connect abnormally to the navel — such as certain urachal disorders — potentially causing symptoms like umbilical discharge or recurrent infections[5]. These cases require medical evaluation and are not the normal state.

Why Does the Navel Differ From Person to Person?

Not all navels are alike. They can be:

• Deep-set (an "innie").
• Protruding (an "outie").
• Narrow.
• Relatively wide.
• Round.
• Oval.
• Closer to a slit shape.

There's natural anatomical variation in the shape of the umbilical ring and its relationship to the surrounding ligaments. Anatomical studies have documented several different patterns for this region[3].

So shape alone isn't enough to judge whether something is wrong.

What matters is the appearance of a new change or accompanying symptoms such as pain, redness, swelling, discharge, or an unusual lump.

How Should the Navel Be Cared For?

Caring for the navel in an adult doesn't need to be complicated. Usually, it's enough to[6]:

1. Gently wash the area with mild, unscented soap and water while showering.
2. Gently remove any accumulated dirt or skin, without harsh scrubbing.
3. Rinse the area thoroughly.
4. Dry it gently, especially if the navel is deep and retains moisture.

Cleveland Clinic guidance notes that the navel can collect sweat, skin cells, dirt, and bacteria, and therefore needs regular, gentle cleaning, while avoiding harsh scrubbing and harsh or scented products[6].

If your navel is deep (an "innie"), it's often enough to wash it with mild, unscented soap and water while showering, then rinse and pat dry thoroughly. Some educational sources, such as UPMC HealthBeat, also suggest a mild saltwater solution (a teaspoon of salt in a cup of warm water) as an additional option for loosening stubborn debris — though this is a practical suggestion rather than an official clinical guideline, and soap and water alone are sufficient for most people[10]. The same sources recommend avoiding creams or oily products inside the navel, since excess moisture can contribute to bacterial or fungal growth.

If your navel protrudes (an "outie"), it's usually easier to clean since it's more exposed to air. Washing it with mild soap and water while showering, then rinsing and drying, is enough.

There's no need to turn navel cleaning into an aggressive daily routine, or to push fingers and tools deep inside.

Cleanliness doesn't mean scrubbing.

The skin inside the navel can be sensitive, and small scratches from scrubbing or prodding can cause irritation and open a path for bacteria to enter.

Do We Need Alcohol or Antiseptics?

It's worth noting that medical opinion isn't entirely unified here.

Some doctors and dermatology clinics do recommend using rubbing alcohol on a cotton swab as part of a weekly navel-cleaning routine, viewing it as an effective way to remove buildup[8]. Other medical sources hold that mild soap and water are usually sufficient, and that alcohol is "okay but not necessary"[9]. These sources note that repeated alcohol use can strip the skin's protective oil layer, causing dryness and irritation, and may sometimes disrupt the skin's natural bacterial balance[9].

In other words: using alcohol occasionally isn't considered a serious mistake according to some sources, but relying on it as a daily or very frequent routine is what most doctors advise against — especially if the area is already irritated or has a scratch.

For ordinary daily hygiene, mild soap and water is a common, nearly universally low-risk recommendation[6].

Repeated use of harsh substances or constant scrubbing can dry out or irritate the skin, and can lead someone into a cycle of:

Harsh cleaning ← irritation ← a feeling of uncleanliness ← harsher cleaning ← more irritation.

The goal isn't to make the navel "sterile" — that's neither necessary nor realistic.

The goal is to keep it clean, dry, and free of skin injury.

What About Oils, Creams, and Ointments?

Here too, it's important to distinguish between skin care and treating a skin condition.

Not every cream is suited to every problem.

If the skin is normal, there's usually no need to apply a range of creams or oils inside the navel purely as prevention.

Some oily products can also increase moisture retention in a deep area, particularly for some people, so they shouldn't be used inside the navel without a specific reason.

If there's a genuine skin problem — inflammation, eczema, a fungal infection, or another skin condition — a doctor may prescribe a specific treatment based on diagnosis.

An important rule emerges here:

A substance suited to one condition isn't necessarily suited to any cut, redness, or itch.

Antifungals, antibiotics, corticosteroids, moisturizers, and protective ointments are all medications or products with different uses.

What About Corticosteroids?

Topical corticosteroids can be an important treatment for certain skin conditions, but they are not a general-purpose ointment for cuts and scratches.

Using a corticosteroid without knowing the cause of redness or itching can mask signs of inflammation, and may be inappropriate for certain types of skin infection.

This is why a strong or medium-strength corticosteroid cream shouldn't be used just because of a minor scratch or redness in the navel, without knowing the cause.

More importantly: skin medications aren't necessarily safe to use inside the eyes or on mucous membranes just because they're safe on skin.

Medication is used in the location, manner, and duration it was designed for or prescribed by a doctor.

What If a Minor Scratch Occurs Inside the Navel?

A minor, accidental scratch can occur during attempts to clean the navel with a cotton swab or small tool, or from fingernails.

If it's just a minor surface scratch with no signs of infection, it's usually best to:

• Stop prodding the area.
• Gently wash it with mild soap and water.
• Dry it.
• Avoid repeated alcohol use or scrubbing.
• Avoid layering multiple products without reason.

For a surface wound, a pharmacist or doctor can be asked about a suitable product to protect the skin while it heals, especially if the area is irritated.

But if pain, redness, or swelling starts to increase, or discharge appears, the situation has changed and needs evaluation.

What Problems Can Appear in the Navel Area?

1. Buildup of Dirt and Skin Cells

Dead skin cells, lint, sweat, and dirt can accumulate inside the navel, especially if it's deep.

In some cases, this material can collect into a solid, dark mass.

This doesn't necessarily mean there's a serious illness.

Regular gentle cleaning and drying are usually sufficient, while avoiding digging or harsh scrubbing. Medical literature has described a rare case of an adult woman who accumulated a lint ball inside her navel, leading to continuous discharge for four months before it was discovered and surgically removed[7].

This mass may sometimes appear dark brown or black, and may feel solid. It may be odorless or accompanied by an odor even without obvious redness — the absence of redness alone doesn't rule out a problem. If it doesn't come out with gentle cleaning, or is accompanied by pain, a strong odor, or discharge, it's best not to try digging it out with a tool, and to seek medical evaluation instead.

2. Inflammation or Infection in the Navel Area

Inflammation can occur in the skin surrounding the navel, with symptoms such as:

• Redness.
• Swelling.
• Pain or tenderness.
• Warmth of the skin.
• Discharge.
• An unusual odor.

Omphalitis in newborns is a different and more significant topic, and can be serious, requiring rapid medical evaluation.

So newborn omphalitis shouldn't be confused with minor irritation in an adult's navel.

In adults, navel infection is less common but can occur, sometimes linked to infection, accumulation of foreign material, or, rarely, fetal remnants like a urachal remnant — one published case documented omphalitis with an umbilical abscess in a 20-year-old woman due to a urachal remnant, requiring antibiotic treatment and surgical drainage[5].

3. Fungal Infections

Warm, moist skin can be a suitable environment for certain fungi to grow.

A fungal infection may appear as:

• Redness.
• Itching.
• A rash.
• Moisture.
• Flaking.
• Sometimes odor or discharge.

People with diabetes, those who are overweight, or those taking antibiotics or immunosuppressant medications for extended periods may be more prone to this type of infection, because these conditions can alter the skin's natural bacterial balance or increase moisture in skin folds.

But not every case of redness in the navel is fungal.

That's why it's best not to use an antifungal based purely on guesswork if the problem is recurring or unclear.

4. Skin Conditions

Some skin conditions can appear in the navel area just as they do elsewhere on the body.

Examples include certain types of eczema, dermatitis, or psoriasis.

In these cases, treatment is directed at the skin condition itself, not at the navel as an independent problem.

This again illustrates why there's no such thing as "one cream for the navel."

5. Umbilical Hernia

An umbilical hernia is different from simply having a protruding navel.

A hernia occurs when tissue, such as fat or a portion of the intestine, passes through a weak area in the abdominal wall at the umbilical ring[3].

It may appear as a bulge or lump at the navel, and may become more noticeable when coughing or straining.

Various factors can increase the likelihood of a hernia, including increased intra-abdominal pressure and certain cases of weight gain or ascites, among others.

Obesity is generally associated with an increased likelihood of abdominal wall hernias, and an older observational study (2012) covering more than 2.8 million patients found that this association with incarceration risk grew stronger as body mass index increased[11]. But this is an observational study showing a statistical association at the group level, not a tool for predicting an individual's personal risk — a higher BMI alone doesn't mean any particular hernia will necessarily become incarcerated.

The truly important sign, regardless of weight, is the appearance of incarceration or strangulation symptoms: sudden, rapidly worsening pain, a lump that becomes hard and painful and can't be pushed back in, nausea or vomiting, abdominal bloating, inability to pass gas or stool, or a change in skin color over the lump (severe redness, blue discoloration, or darkening). This situation calls for going to the emergency room immediately, not waiting for a routine doctor's appointment.

Not every protrusion at the navel is a hernia, which is why it may need medical examination to confirm.

What About Putting Olive Oil in the Navel?

This is a very widespread habit, and it deserves a closer look.

Many people believe that placing drops of olive oil in the navel can "treat" problems in distant organs — such as poor eyesight, joint pain, or fertility issues. This belief is tied to a common idea that the navel is connected to an internal network that carries the oil to different organs of the body.

There's no scientific evidence supporting this. As explained earlier, there's no channel or "gland" behind the navel that transports any substance to internal organs after birth. Specialized medical reviews have examined this practice specifically — including claims about treating joint pain — and found no scientific basis for it[12][13].

So why do some people feel genuinely better sometimes?

The feeling of improvement is largely tied to the placebo effect: when a person believes a particular practice will help them, that belief can temporarily change how they perceive pain, without that meaning actual healing has occurred[12].

Olive oil is also genuinely beneficial for dry skin, and can soften cracked skin — but this is an effect on the navel's own skin, not absorption reaching internal organs[13].

Repeated use of olive oil can irritate certain sensitive skin types, and the warm, moist environment inside the navel can become more conducive to fungal growth if oil is added regularly[13].

When Should You See a Doctor?

It's best to seek medical evaluation if one or more of the following signs appear:

• Clear or persistent pain.
• Swelling that increases rather than improving.
• Redness spreading around the navel.
• Clear warmth in the skin.
• Pus or unusual discharge.
• A strong odor with discharge.
• Recurrent or unexplained bleeding.
• A new or painful lump.
• A bulge that looks like a hernia.
• Recurrent discharge from the navel with no clear cause.
• Fever or general symptoms alongside local inflammation.

These symptoms shouldn't always be interpreted as simply "not cleaning enough."

Persistent or recurring discharge, for example, can have multiple causes — some skin-related, some inflammatory, and some rare cases tied to fetal remnants[5][7].

What Does a Doctor Do When Examining the Navel?

Seeing a doctor doesn't necessarily mean the situation is serious.

The evaluation usually starts with simple questions and an examination of the area.

The doctor may ask:

• When did the problem start?
• Is there pain?
• Is there itching?
• Is there discharge?
• What color is the discharge?
• Does it have an odor?
• Is there fever or chills?
• Did a scratch or injury occur in the area?
• Was a cream, ointment, or antiseptic used?
• Is there a lump or swelling?
• Is this the first time this has happened, or is it recurring?

Then the skin, the navel, and the surrounding area are examined.

In some cases, if there's reason to look for a deeper problem, the doctor may order additional tests such as ultrasound or CT imaging, depending on symptoms and clinical suspicion. These tests have been used in rare cases of navel infection linked to urachal remnants[5].

What Should a Patient Tell Their Doctor?

It's important not to feel embarrassed about mentioning small details.

It's helpful to mention any of the following to the doctor, if they occurred:

• Scratching with fingernails.
• Using a cotton swab.
• Scrubbing the area hard.
• Using alcohol or an antiseptic.
• Applying oil or cream.
• Using an old ointment.
• Attempting to remove a lump or discharge on one's own.

This information isn't embarrassing or trivial — a doctor doesn't need a perfect story, just honest information that helps them understand the cause of the irritation or injury.

Common Mistakes in Navel Care

Mistakes that can be avoided include:

Inserting Tools Deeply and Repeatedly

Because excessive cleaning can cause scratches and irritation.

Harsh Scrubbing

Cleanliness doesn't require forcibly removing everything.

Repeated Use of Alcohol or Strong Antiseptics

There's no need to sterilize the navel daily, and unnecessary use of harsh substances can irritate the skin[6].

Applying Any Cream Just Because of Redness

Redness has many causes, and treatment depends on the cause.

Using Corticosteroids as a Wound Ointment

Corticosteroids have specific medical uses and aren't a general treatment for every scratch or irritation.

Using Oils Excessively Inside a Deep Navel

Because the goal isn't adding moisture, but keeping the area clean and dry.

Trying to Force Everything Out

If there's a solid mass, recurrent discharge, or pain, it may be better to have it examined by a doctor rather than continuing to dig and clean.

The Navel Isn't a Diseased Organ Just Because It Looks Different

It's also important not to let attention to cleanliness turn into excessive worry.

Variation in navel shape between people is normal[3].

Having a deep navel doesn't mean illness.

Having a protruding navel doesn't necessarily mean a hernia.

A small amount of dirt doesn't mean infection.

Passing redness after friction doesn't necessarily mean serious inflammation.

But persistent or worsening change, pain, discharge, swelling, fever, or a new lump are things worth paying attention to.

Practical Summary

The navel isn't just a small hollow in the middle of the abdomen, nor is it an open channel leading to the body's internal organs.

It's a region of the abdominal wall carrying anatomical traces of fetal life. It connects internally to important fibrous remnants, including the median umbilical ligament, the medial umbilical ligaments, and the round ligament of the liver.

After birth, the umbilical cord's functional role ends, but the region retains anatomical and medical importance.

Caring for it is simpler than one might think:

Gentle cleaning, good drying, and avoiding prodding, scrubbing, or randomly using medications.

And if a genuine problem appears, the answer isn't always more cleaning.

Sometimes the best thing to do is stop prodding the area, observe it, and seek medical advice if symptoms persist or signs appear that warrant an exam.

Taking care of the body doesn't mean constantly doing something.

Sometimes it means knowing when to act, when to stop, and when to ask for help.
