Umbilical hernias in infants do not always require surgery; only a small portion necessitates it. Surgery is needed mainly if the child is over two years old and still has a noticeable umbilical hernia, or if the hernia's ring diameter exceeds 2 cm. In these cases, the chances of natural healing are slim, and surgical intervention to remove the hernia sac and repair the abdominal wall defect may be necessary. In other cases, 80% of umbilical hernias can heal by the age of two as the abdominal muscles strengthen and develop with age, often causing the hernia ring to narrow and close on its own, achieving healing without any additional treatment. The previously used method of compressing the hernia with a hernia belt has been proven ineffective and is no longer employed.

How does an umbilical hernia gradually improve?

Umbilical hernia refers to a protrusion formed by abdominal contents through the weak area of the umbilicus. After the umbilical cord falls off in the neonatal period, the umbilical scar area, due to the phase when the umbilical cord passes through the abdominal wall during fetal life, creates a congenital separation in the abdominal wall. In infancy, the abdominal muscles on either side do not completely close at the midline, leaving a defect and forming the umbilical ring. When crying, coughing, or struggling increases intra-abdominal pressure, the abdominal contents gradually push outwards through the umbilicus, forming an umbilical hernia. Most umbilical hernias can heal on their own within one year through the contraction of the umbilical fascial ring. Therefore, unless incarceration occurs, observation and waiting with non-surgical treatment can be adopted to promote healing before the age of two.

Is umbilical hernia hereditary?

Umbilical hernia is not a hereditary disease and generally does not occur genetically. Umbilical hernia is due to the incomplete healing of the umbilical ring, causing the abdominal organs to protrude through the umbilical ring, and is a congenital disease. Developmental inadequacies of the navel, or the presence of scar tissue, thinness, and lack of toughness in the navel area can lead to this condition when abdominal pressure increases. In general, children with an umbilical hernia may show discomfort, which can manifest as frequent crying or constipation. For most cases of umbilical hernia, conservative treatment is an option. In children under two years old, surgery can be avoided by using adhesive tape treatment, which can achieve very good therapeutic effects. If the diameter of the umbilical ring is still greater than 1.5 cm after the age of two, timely surgery is necessary. For adults with umbilical hernia, incarceration and strangulation are common, and surgery is recommended as soon as a clear diagnosis is made.

Is it normal for there to be moving gas inside an umbilical hernia?

It is abnormal for there to be movement of gas within an umbilical hernia. This could potentially indicate that the contents of the hernia include a part of the intestine. When excessive intestine is present within the hernial sac of an umbilical hernia, it can easily lead to the movement of gas as it moves through the intestine. This condition is relatively common in clinical settings, and it is also used as a symptom to diagnose the possibility of an umbilical hernia. Therefore, when there is movement of gas observed in an umbilical hernia, it is crucial to reposition the hernia back into place using massage and other standard techniques to avoid prolonged entrapment of the intestine, which can lead to ischemic necrosis and the possible formation of an incarcerated hernia. This condition should be actively treated to prevent complications.

Can an umbilical hernia cause abdominal bloating?

Umbilical hernias can potentially cause abdominal distention because they may become incarcerated or even strangulated. The contents entering the umbilical hernia can include the omentum or intestines. If the small intestine or colon becomes incarcerated in the hernia, it can cause partial intestinal obstruction, with symptoms potentially including abdominal pain, distension, and nausea and vomiting. In cases where an umbilical hernia becomes incarcerated or ruptured, timely surgical treatment is necessary. Generally, umbilical hernias in children before the age of two do not require surgical intervention unless incarceration occurs. Most can be treated with adhesive strapping to allow for natural healing. If the umbilical ring still has a diameter greater than 1.5cm after the age of two, surgery should be considered promptly. For children over five with an umbilical hernia, surgery is recommended regardless of the specifics. Adults diagnosed with an umbilical hernia are also advised to undergo surgical treatment as soon as possible.

Can you take a bath with an umbilical hernia?

Umbilical hernia is primarily due to the weak abdominal wall at the navel, allowing abdominal contents to pass through and protrude at the surface, forming a lump. In children under two years old, if the umbilical hernia does not cause incarceration or significant redness and swelling on the skin's surface, bathing is generally not affected. In adults, umbilical hernias usually do not heal on their own and often require surgical treatment, otherwise, the hernia tends to enlarge. As long as the umbilical hernia does not cause significant incarceration requiring emergency surgery, or local inflammatory skin reactions, it does not affect the patient's ability to bathe. Even if surgery is necessary for an umbilical hernia, it is considered an elective procedure.
