The umbilical hernia is a particular type of hernia that appears exactly in the area of the navel or around it (in which case it is referred to as a paraumbilical hernia). Its distinctive characteristic is that it is associated with the natural anatomical weakness that exists in the abdominal wall at the point of the umbilical ring. It involves a gap or incomplete closure of the abdominal muscular layer, which allows intra-abdominal tissues, such as the omentum (that is, the peritoneal fat) or even a portion of the intestine, to protrude outward, forming a visible or sometimes subtle bulge. The typical appearance of the navel, with the indentation at the center of the abdomen, is often lost in cases of a larger hernia and replaced by a rounded swelling. This swelling may reduce when the patient lies down and reappear when standing upright or when pressure is applied to the abdomen. However, there are also cases where a small umbilical hernia has formed and may go unnoticed. What happens in this situation, and what treatment options are available?

Factors that contribute to the development of an umbilical hernia

The causes of an umbilical hernia are generally complex. In childhood, particularly in newborns and infants, the main cause is the incomplete closure of the umbilical ring after birth. In most cases, this condition resolves on its own by the end of the first year of life.

In adults, the condition often develops due to a chronic increase in intra-abdominal pressure. Factors that weaken the stability of the abdominal wall include obesity, repeated pregnancies, severe constipation, the presence of ascites, chronic respiratory pressure from persistent coughing, and heavy lifting.

Smoking and genetic predisposition also increase the likelihood of developing an umbilical hernia, as they are associated with impaired tissue healing and abnormalities in the structure of connective tissue.

In pregnant women, a protrusion of the navel is often observed due to the increase in abdominal volume. However, in most cases this appearance resolves on its own after childbirth. If the swelling persists and does not subside, it is not simply a temporary stretching but a true hernia, which requires definitive treatment.

What happens if a small umbilical hernia develops?

Most people associate a hernia with a large, visible bulge in the abdominal area. However, it is very important to understand that umbilical hernias are not always large or obvious in appearance. In many cases, the hernia is small in size, without a noticeable swelling or pain.

These so-called small umbilical hernias are often underestimated, both by patients and by those around them. The absence of visible symptoms can create the impression that a small umbilical hernia is harmless. However, the reality is different.

In fact, the small size of the hernia is what can make it more dangerous in certain cases. The small opening, or narrow defect, increases the likelihood that the tissue protruding through it may become trapped within the hernia opening.

This complication is known as incarceration (strangulation) and can occur suddenly, without warning symptoms. Strangulation leads to a disruption of blood circulation to the trapped intestine or fatty tissue, potentially causing tissue necrosis, inflammation, and a serious risk to the patient’s health and life.

Even a very small umbilical hernia can suddenly develop into a surgical emergency.

Symptoms that are often overlooked

Small umbilical hernias are often accompanied by very mild symptoms, such as a vague feeling of heaviness or pulling around the navel, mild pain during heavy lifting or coughing, or a subtle swelling that appears occasionally and disappears easily when lying down. Many patients assume that these discomforts are not important. It is precisely this misleading picture that often delays diagnosis and treatment.

The diagnosis of a small umbilical hernia is mainly based on a careful clinical examination by a general surgeon. During the examination, palpation can reveal the defect in the abdominal wall even when no visible bulge is present. When the diagnosis is not obvious, ultrasound or CT scanning can confirm the presence of the hernia and allow evaluation of its contents.

The importance of early treatment

In practice, a small umbilical hernia can be considered a “ticking time bomb.” If left untreated, it will gradually increase in size, as the daily forces exerted on the abdominal wall further weaken it. Over time, the defect becomes larger, allowing an increasing portion of intra-abdominal tissue to protrude through the hernia opening, while the risk of complications such as strangulation also increases.

Beyond the risk of strangulation, even a small hernia may gradually start causing symptoms, including chronic pain, discomfort during movement, and limitations in daily activities. As a result, the patient may eventually need to adapt their lifestyle, avoiding physical strain as well as certain athletic or professional activities.

Definitive treatment of an umbilical hernia

Surgical repair is the only method that offers a definitive solution to the problem, even when the hernia is small and asymptomatic. In modern medicine, laparoscopic and robotic surgery have transformed the patient’s experience. With very small incisions, specialized instruments, and three-dimensional visualization, the surgeon can repair the defect with minimal tissue trauma. The placement of a surgical mesh strengthens the abdominal wall and helps prevent possible future recurrences.

When this procedure is performed in a planned and timely manner, it is associated with faster recovery, reduced postoperative pain, and an excellent aesthetic result. On the other hand, delaying treatment until a small umbilical hernia causes complications significantly increases the risk and the likelihood of adverse outcomes.

Why a small umbilical hernia is not harmless

It is important to understand that a small umbilical hernia, no matter how subtle it may seem, is a condition that will never resolve on its own. Its small size does not reduce the likelihood of worsening. On the contrary, the narrow opening of the hernia can actually create a higher risk of acute complications. There is no evidence that simple monitoring without treatment is a safe long-term strategy.

Early surgical repair is the responsible choice that protects the patient from sudden and serious problems. With modern minimally invasive techniques, the repair can be performed safely, allowing a faster return to daily activities and eliminating the anxiety that the hernia could suddenly lead to an emergency hospital visit.

In general, a small umbilical hernia is often considered “silent” because it may not be immediately noticeable. However, this does not mean it is less dangerous. A patient diagnosed with this condition—even if no discomfort is present—should think about their long-term health in a responsible way. A hernia, regardless of its size, is a progressive condition. It is not something harmless or temporary, but rather an anatomical defect that requires definitive correction.

The responsible approach is to treat it early using the most modern surgical techniques, in order to avoid unpleasant consequences that, unfortunately, are very likely to occur sooner or later if the condition remains untreated.
