Umbilical Hernia

An umbilical hernia is a common medical condition that affects many individuals, particularly infants and adults with weakened abdominal muscles. This condition occurs when a part of the intestine or fatty tissue protrudes through a weakened muscle near the belly button, known as the umbilical ring. In this comprehensive blog, let's delve into the causes, symptoms, and treatment modalities for umbilical hernia, shedding light on this misunderstood condition.

What is an Umbilical Hernia?

An umbilical hernia is one of the types of abdominal hernia that occurs when the abdominal muscles fail to close properly around the umbilical ring. It results in a small opening that allows the intestines or fatty tissue to push through, causing a bulge near the belly button. While this condition is common in infants, it can also affect adults, especially those with a weakened abdominal wall, due to various factors such as obesity, pregnancy, or previous abdominal surgery. 

Causes of Umbilical Hernia

Various factors can be a reason for umbilical hernia, such as: Congenital impairment: Umbilical hernia usually develops in infants when the abdominal muscles fail to close completely before birth. Premature birth or certain health conditions, such as Down syndrome, can increase the possibility of developing an umbilical hernia. 

  • Increased muscle pressure: Various factors, such as obesity, pregnancy, strenuous physical activities, or persistent coughing, can increase pressure on the abdominal wall, leading to a weakening of the muscles and the development of a hernia. 
  • Gastrointestinal ailments: Chronic constipation or frequent episodes of straining during bowel movements can apply unduly pressure on the abdominal wall, increasing the risk of an umbilical hernia.
  • Connective tissue disorders, like Marfan syndrome or Ehlers-Danlos syndrome, can cause weakening of the connective tissue, increasing the possibility of hernias, including an umbilical hernia.

Factors such as a family history of hernias and previous abdominal surgeries can also contribute to the development of an umbilical hernia.

Signs and Symptoms of Umbilical Hernia

While small umbilical hernias may not cause discomfort, larger hernias or those trapped may develop symptoms. Here are some signs and symptoms of umbilical hernia: 

  • The most apparent sign in infants is a visible bulge near the belly button, which becomes more distinguishable when the baby cries or strains. This bulge is usually painless and soft to the touch. 
  • However, an umbilical hernia can cause discomfort and pain for adults, particularly when lifting heavy objects or engaging in strenuous activities. 
  • An inflamed or infected hernia may cause the area around the navel button to be swollen or red.
  • The hernia site may feel tender to the touch.
  • Other umbilical hernia symptoms may include a feeling of fullness, nausea, and increased bulge size.

Risk factors

Certain risk factors can increase an individual's possibility of developing an umbilical hernia. For infants, premature birth and a family history of hernias are common risk factors. In adults, factors such as obesity, multiple pregnancies, and previous abdominal surgeries can weaken the abdominal muscles, making them more susceptible to hernias. Additionally, chronic coughing, connective tissue disorders, and a sedentary lifestyle can also contribute to an umbilical hernia.

Complications

While umbilical hernias are generally considered harmless, complications can sometimes arise. If the hernia becomes incarcerated, the protruding tissue becomes trapped and cannot be pushed back into the abdomen. It can cause intense abdominal pain, nausea, and vomiting. 

In rare instances, the hernia can become strangulated, obstructing the blood supply to the trapped tissue. This situation requires immediate medical intervention, as it can lead to tissue death and infection, necessitating emergency surgery.

Diagnosis of Umbilical Hernia

Diagnosing an umbilical hernia involves a thorough assessment of clinical presentation and physical examination by a doctor. 

  • Physical examination: The doctor will thoroughly inspect the belly button area and gently press on the area around the umbilicus to feel for the presence of a hernia and assess its shape, size, and tenderness.
  • Cough test: The doctor may ask the patient to cough or strain the abdomen, making the hernia more prominent and aiding in diagnosis.
  • Imaging studies: In some cases, doctors may recommend imaging tests, such as an ultrasound or an abdominal CT scan, to confirm the diagnosis and analyse the size and contents of the hernia. These imaging tests can also help identify any complications, such as incarcerated or strangulated hernias.

Treatment for Umbilical Hernia

The treatment approach for umbilical hernia depends on various factors, including the extent of the hernia, the severity of manifestations, and the patient's age. 

Small umbilical hernias in infants often resolve on their own as the abdominal muscles strengthen over time. However, if the hernia persists beyond the age of four or becomes symptomatic, doctors may recommend surgical intervention. 

Doctors typically recommend surgical repair in adults to prevent complications and alleviate discomfort. The procedure involves pushing the herniated tissue back into the abdomen and strengthening the abdominal muscles with sutures or a mesh patch.

When to see a doctor

It is essential to seek medical attention if you suspect that you or your child has an umbilical hernia. While small, painless hernias in infants may not require immediate intervention, monitoring them closely and consulting a healthcare professional for guidance is crucial. In adults, the presence of symptoms such as pain, discomfort, or an enlarging bulge should prompt a visit to the doctor. If you experience sudden, severe pain or notice changes in the colour of the bulge, seek immediate medical guidance, as these may be signs of a strangulated hernia.

Conclusion

An umbilical hernia is a common condition that can affect both infants and adults. Understanding the reasons, symptoms, and umbilical hernia treatment options is essential for early detection and appropriate management. While most umbilical hernias do not cause significant problems, it is necessary to consult a doctor for an accurate diagnosis and to determine the best course of action. Whether it is monitoring an infant's hernia or considering surgical repair for an adult, timely intervention can prevent complications and provide immediate relief from discomfort.

FAQs

1. How serious is an umbilical hernia?

Umbilical hernias are generally not considered serious and often resolve on their own in infants. However, in adults, they can cause discomfort and may lead to complications if left untreated.

2. Can you heal an umbilical hernia without surgery?

While small umbilical hernias in infants may resolve without surgical intervention, larger or symptomatic hernias often require surgical repair in infants and adults.

3. What size hernia needs surgery?

The size of the umbilical hernia alone does not determine the need for surgery. Factors such as symptoms, patient age, and the risk of complications are also considered when deciding on surgical intervention.

4. Is umbilical hernia surgery painful?

During umbilical hernia surgery, patients are typically under anaesthesia and should not experience pain. After the procedure, some discomfort and soreness are common but can be managed with appropriate pain medication.

5. What are the side effects of umbilical hernia surgery?

Side effects of umbilical hernia surgery may include temporary pain, swelling, bruising, or infection at the incision site. In rare cases, hernia recurrence or damage to surrounding structures may occur. Following post-operative instructions and seeking medical attention if any concerning symptoms arise is essential.
