Umbilical Hernias in Infants Often Close; Adult Ones May Not

Have you noticed a small bulge at your baby’s belly button — or your own — that seems to pop out with coughing or straining? That’s often an umbilical hernia: tissue, fat, or sometimes part of the intestine pushing through a weak spot in the abdominal wall near the navel.

It’s common in infants and happens in adults too. Some hernias can be safely watched. Others need a planned surgical repair. The right approach depends on your situation, and that’s what this guide walks you through.

Overview

An umbilical hernia is a protrusion of tissue through a weak area in the abdominal wall at the belly button. It may contain fat or a small segment of intestine, creating a visible or palpable bulge. In many people, the bulge becomes more noticeable when coughing, crying, straining, or standing and may flatten when lying down.

Umbilical hernias are especially common in babies because the opening in the abdominal wall where the umbilical cord passed may not close completely right away. They also occur in adults, particularly when pressure inside the abdomen increases over time or the tissues weaken. Although many umbilical hernias are not immediately dangerous, they should be assessed to determine whether observation or repair is the safest approach.

What makes it different from other abdominal wall hernias? The location — it develops right at the navel. People sometimes lump it in with hernias in general, but the age at which it appears, the symptoms, and the treatment choices can all differ. A careful exam tells us whether it’s a simple hernia that slides back in easily, or one more likely to trap tissue.

Symptoms and what people usually notice

The most common sign of an umbilical hernia is a small bulge or swelling at the belly button. In infants, it is often most visible when crying, coughing, or straining. In adults, the bulge may be noticed while standing, lifting, exercising, or after meals, and it may become less obvious when resting flat.

Some umbilical hernias cause no discomfort. Others may lead to a feeling of pressure, mild tenderness, aching, or discomfort with movement and exertion. Symptoms can vary from day to day, especially if the hernia slides in and out easily.

Some signs shouldn’t wait. If the bulge turns firm, painful, or won’t push back in, or the skin over it becomes red or discolored, get medical help promptly. Nausea, vomiting, bloating, or pain that suddenly gets worse can mean tissue is trapped and losing its blood supply.

• Pressure, tenderness, or aching in adults
• Painful, hard, or non-reducible bulge as a possible emergency sign

Causes and risk factors

An umbilical hernia forms when there is both a weak point in the abdominal wall and enough internal pressure to push tissue outward. In babies, the cause is usually incomplete closure of the umbilical ring after birth. In adults, the weakness may have been present for years or may develop gradually as tissues stretch and thin.

Anything that raises pressure inside the abdomen can increase risk. Common factors include pregnancy, obesity, repeated heavy lifting, chronic coughing, constipation with frequent straining, and fluid buildup in the abdomen. Previous abdominal surgery, multiple pregnancies, and aging may also make the abdominal wall more vulnerable.

Umbilical hernias can occur in men and women, but certain risk patterns differ by age group. Infant cases are often harmless and self-limited, while adult cases are more likely to persist and enlarge over time. In adults, clinicians also consider whether there are related abdominal wall defects such as an inguinal hernia or broader tissue weakness that may influence treatment planning.

How doctors diagnose an umbilical hernia

Diagnosis usually begins with a medical history and physical examination. A doctor examines the belly button area while the patient is lying down and standing, and may ask the person to cough or gently strain so the bulge becomes easier to assess. The clinician checks whether the hernia is reducible, how large the opening may be, and whether there are signs of pain, skin changes, or trapped tissue.

In many straightforward cases, no tests are needed. Imaging may be recommended if the diagnosis is uncertain, the patient has obesity or significant pain, there is concern for another abdominal problem, or surgery is being planned. Ultrasound is often helpful, and in some adults a CT scan may be used for a clearer view of the abdominal wall and hernia contents.

Your doctor will also look at the bigger picture: whether you smoke, your weight, other medical conditions, past operations, and any symptoms that point to a bowel obstruction. All of this shapes the decision — is it safe to watch and wait, or should surgery come sooner?

Treatment options

Treatment depends on age, symptoms, hernia size, and risk of complications. In infants, many umbilical hernias close spontaneously during early childhood, so doctors often recommend observation if the child is otherwise well and the hernia is soft and reducible. Regular follow-up helps confirm whether the opening is shrinking and whether repair may be needed later.

In adults, umbilical hernias usually do not close on their own. If the hernia causes discomfort, enlarges, interferes with daily activity, or cannot be reduced easily, planned repair is commonly advised. Surgery may also be recommended for smaller hernias if the anatomy suggests a higher chance of incarceration or if the patient prefers repair after discussing risks and benefits.

Repair can be performed with open or minimally invasive techniques. The surgeon returns protruding tissue to its normal position and closes the defect, sometimes reinforcing the area with mesh depending on the size of the opening, tissue quality, and recurrence risk. In selected patients, laparoscopic surgery may be appropriate, while others benefit from a standard open approach. The most suitable method is individualized after clinical assessment.

Emergency treatment is needed if the hernia becomes incarcerated or strangulated, meaning tissue is trapped and may lose blood supply. In these situations, prompt surgery helps prevent damage to the intestine and other complications. For this reason, a previously mild hernia should still be monitored for any sudden change in pain, firmness, or color.

Prevention, self-care, and living with an umbilical hernia

Not every umbilical hernia can be prevented, especially in infants or when there is an inherited tendency toward weaker connective tissue. However, reducing abdominal strain may lower the chance that a hernia worsens or recurs. Weight management, treatment of chronic cough, avoiding tobacco use, and addressing constipation can all help reduce repeated pressure on the abdominal wall.

Watching a small hernia as an adult? Lift safely, avoid unnecessary straining, and follow your doctor’s advice about activity. Support garments come up sometimes, but be clear on this: they don’t repair the defect and are no substitute for a medical evaluation. If the bulge changes shape, hurts more, or stops going back in, get the plan reviewed promptly.

After surgical repair, recovery advice typically includes gradual return to activity, attention to wound care, and temporary limits on heavy lifting. Patients should follow the surgeon’s instructions closely, since healing time varies by technique and by individual health status. If a broader evaluation of the abdominal wall is needed, some people may also benefit from assessment by specialists experienced in general surgery and hernia care.

When to seek medical care

Medical review is appropriate for any new or persistent bulge at the belly button, even if it is painless. An evaluation helps confirm whether it is truly an umbilical hernia and whether observation or repair is the better option. In infants, caregivers should mention the bulge during routine pediatric visits and return sooner if the swelling becomes painful, discolored, or difficult to reduce.

Adults should arrange an appointment if the hernia is enlarging, causing pressure or pain, limiting exercise or work, or becoming harder to push back in. A doctor can also check for related issues such as additional abdominal wall defects or symptoms that suggest another cause of abdominal discomfort.

Get urgent care if you have sudden severe pain, vomiting, fever, abdominal swelling, redness or purple discoloration over the hernia, or a bulge that won’t go back in. These can be signs of incarceration or strangulation — both need prompt treatment. And if you’d like a full assessment, centers such as Acıbadem Health Point offer multidisciplinary hernia diagnosis and treatment for international patients in JCI-accredited hospitals.
