An umbilical hernia is a common condition that affects both adults and children, occurring when a portion of the intestine or abdominal tissue protrudes through a weakness in the abdominal wall near the navel. This condition can cause discomfort and, in some cases, lead to serious complications if left untreated. Understanding the symptoms and available treatment options is crucial for those who may be dealing with an umbilical hernia.
This article aims to provide a comprehensive overview of umbilical hernias, covering their causes, symptoms, and diagnosis. It will also explore the various treatment approaches, from watchful waiting to surgical intervention. By delving into these aspects, readers will gain valuable insights to help them recognize the signs of an umbilical hernia and make informed decisions about their healthcare.
Understanding Umbilical Hernias
An umbilical hernia occurs when a portion of the intestine or abdominal tissue protrudes through a weakness in the abdominal wall near the navel. This condition is very common in infants and young children, particularly in babies born prematurely. The hernia appears as a painless lump in or near the belly button, which may get bigger when laughing, coughing, crying, or going to the toilet, and may shrink when relaxing or lying down.
During pregnancy, the umbilical cord passes through an opening in the baby’s abdomen. This opening should close shortly after birth, but in some cases, the muscles don’t seal completely, leaving a weak spot in the surrounding muscle wall. An umbilical hernia can develop when fatty tissue or a part of the bowel pokes through into this area near the navel.
Risk Factors
Several factors can contribute to the development of an umbilical hernia in adults, including:
- Obesity
- Multiple pregnancies
- Fluid in the abdominal cavity
- Previous abdominal surgery
- Long-term peritoneal dialysis to treat kidney failure

Types of Umbilical Hernias
Umbilical hernias can be classified into three types:
- Reducible: A hernia that can be pushed back into place.
- Incarcerated: A hernia that becomes trapped and can no longer be pushed back into the abdominal cavity.
- Strangulated: A hernia that has its blood supply cut off, leading to tissue damage and requiring emergency surgery.
In many cases, the umbilical hernia goes back in, and the muscles reseal by the time a child is 4 or 5 years old. However, without treatment, the hernia will probably get worse over time in adults. Surgery may be recommended to push the bulge back into place and strengthen the weakness in the abdominal wall.
Recognizing Umbilical Hernia Symptoms
The most common sign of an umbilical hernia is a visible bulge or swelling near the belly button. This bulge may be more noticeable when the individual cries, coughs, or strains, and it may shrink or disappear when they are relaxed or lying down. The symptoms of an umbilical hernia can vary depending on the age of the affected individual.
Common Signs in Infants
In infants, an umbilical hernia may be especially evident when the baby cries, causing the belly button to protrude. This is a classic sign of an umbilical hernia. The swelling is usually soft to the touch and typically painless. Umbilical hernias in children often close on their own by the age of 4 or 5, but some may remain open longer.

Symptoms in Adults
Adults with umbilical hernias may experience abdominal discomfort or pain near the belly button. The bulge may be more apparent when standing or straining and may reduce in size when lying down. In some cases, the hernia may become incarcerated, meaning that the protruding tissue becomes trapped and cannot be easily pushed back into the abdominal cavity. This can lead to severe pain, tenderness, swelling, and discoloration at the site of the hernia.
When to Seek Medical Attention
It is essential to seek medical attention if you suspect that you or your child has an umbilical hernia. In infants, consult with the baby’s doctor if you notice a bulge near the belly button. Seek emergency care if the baby appears to be in pain, begins to vomit, or if there is tenderness, swelling, or discoloration at the site of the hernia.
For adults, it is crucial to consult with a doctor if you notice a bulge near your navel. Seek emergency care if the bulge becomes painful or tender, as this may indicate an incarcerated hernia. Prompt diagnosis and treatment can help prevent complications and ensure the best possible outcome.
Diagnosis and Evaluation
The diagnosis of an umbilical hernia involves a combination of physical examination and, in some cases, imaging tests. A healthcare provider will look for a bulge or swelling near the belly button, which may be more noticeable when the individual cries, coughs, or strains. The swelling is usually soft to the touch and may shrink or disappear when the person is relaxed or lying down.
During the examination, the provider will determine if the hernia is reducible, meaning it can be pushed back into the abdominal cavity. They will also assess for signs of incarceration, where the protruding tissue becomes trapped and cannot be easily pushed back. Symptoms of an incarcerated umbilical hernia include abdominal pain, tenderness, constipation, fever, a full, round abdomen, and a discolored bulge.
Physical Examination
A thorough physical examination is the primary method for diagnosing an umbilical hernia. The healthcare provider will inspect and palpate the area around the belly button to identify any swelling or protrusion. They may ask the patient to cough or strain to make the hernia more apparent. The provider will also assess the hernia’s reducibility and check for signs of incarceration or strangulation.
Imaging Tests
In some cases, imaging tests may be used to confirm the diagnosis or assess for complications. These tests may include:
- Abdominal ultrasound: This non-invasive test uses sound waves to create images of the abdominal wall and can help identify the presence of a hernia.
- Computed tomography (CT) scan: A CT scan provides detailed cross-sectional images of the abdomen and can help visualize the hernia and any associated complications.
- Magnetic resonance imaging (MRI): An MRI uses powerful magnets and radio waves to create detailed images of the abdominal wall and surrounding structures.
Differential Diagnosis
When evaluating a patient with a suspected umbilical hernia, healthcare providers must consider other conditions that may present with similar symptoms. The differential diagnosis may include:
- Lipoma: A benign fatty tumor that can develop near the belly button
- Lymphadenitis: Inflammation of the lymph nodes in the abdominal wall
- Hematoma: A collection of blood that may form due to injury or surgery
- Abscess: A localized collection of pus that can develop in the abdominal wall
- Tumor: In rare cases, a growth or mass near the belly button may be mistaken for a hernia
By carefully examining the patient and considering the differential diagnosis, healthcare providers can accurately diagnose an umbilical hernia and recommend the most appropriate treatment plan.
Treatment Options and Management
The management of umbilical hernias involves a combination of conservative approaches and surgical interventions, tailored to the individual patient’s needs and the severity of their condition. The primary goal of treatment is to alleviate symptoms, prevent complications, and improve the patient’s overall quality of life.
Conservative Approaches
In cases where the umbilical hernia is small and asymptomatic, a conservative approach may be recommended. This typically involves close monitoring of the hernia by a healthcare provider and lifestyle modifications, such as avoiding heavy lifting or straining, maintaining a healthy weight, and using supportive garments like abdominal binders or trusses. Regular follow-up appointments are essential to assess any changes in the hernia’s size or the development of symptoms.

Surgical Interventions
Surgical repair is often necessary when an umbilical hernia causes significant discomfort, pain, or is at risk of complications like incarceration or strangulation. The surgical procedure, known as an umbilical herniorrhaphy, aims to reposition the protruding tissue back into the abdominal cavity and reinforce the weakened area of the abdominal wall.
The surgery can be performed using either an open or laparoscopic approach, depending on factors such as the size of the hernia, the patient’s overall health, and the surgeon’s preference. Open surgery involves making an incision near the hernia site, while laparoscopic surgery uses smaller incisions and specialized instruments to repair the hernia. In both techniques, the surgeon may use sutures or mesh to strengthen the abdominal wall and reduce the risk of recurrence.
Post-Treatment Care
Following umbilical hernia repair, patients typically experience some pain and discomfort, which can be managed with prescribed pain medication. Most individuals can return home on the same day of the surgery, although an overnight hospital stay may be necessary for some patients with certain medical conditions.
During the recovery period, patients are advised to avoid strenuous activities and heavy lifting for several weeks to allow proper healing. Gradually, they can resume their normal daily routines as tolerated. Postoperative care instructions, such as wound care and follow-up appointments, will be provided by the healthcare team to ensure a smooth recovery and monitor the patient’s progress.
Conclusion
Understanding umbilical hernias is crucial for proper management and timely treatment. This condition, which affects both children and adults, can range from a minor issue that resolves on its own to a serious problem requiring surgical intervention. Recognizing the symptoms and seeking medical advice early on can help prevent complications and ensure the best possible outcome.
Ultimately, the approach to treating umbilical hernias depends on individual circumstances. While some cases may only need monitoring, others might require surgery to repair the weakness in the abdominal wall. By staying informed about the causes, symptoms, and treatment options, individuals can make well-informed decisions about their health or that of their children, leading to better overall care and peace of mind.
