Umbilical Hernia: Symptoms, Causes, Diagnosis and Treatment
Table of Contents
Key takeaways
- An umbilical hernia is a belly-button bulge caused by bowel or fat pushing through a weakness in the abdominal muscles.
- Many childhood umbilical hernias close by themselves, but adult umbilical hernias are less likely to resolve without surgery.
- Adults, pregnancy, obesity and ascites can increase strain around the navel and make a hernia more likely.
- Severe tummy pain, vomiting, colour change over the hernia or inability to pass wind or stool can signal strangulation and needs 999.

Overview
An umbilical hernia appears as a swelling at or near the belly button. In babies it is often noticed when crying or straining and is usually painless. In adults it may appear after gradual weakening of the abdominal wall, pregnancy, weight gain, heavy strain or abdominal fluid. The lump may feel soft and reduce when lying down, or it may become firmer and more uncomfortable. For women, umbilical and paraumbilical hernias may appear during or after pregnancy, and they can be confused with diastasis recti, scar tissue or general abdominal bloating. A clinical assessment helps confirm whether the bulge is a true hernia and whether monitoring or repair is appropriate.
Symptoms and concerns
Umbilical hernia can present differently from person to person. The pattern, duration, severity and associated symptoms matter because they help separate mild or expected symptoms from problems that need urgent assessment.
- a soft lump or swelling at the belly button that may enlarge when coughing, crying or straining
- discomfort, pressure or aching around the navel, especially in adults
- a bulge that may be pushed back gently when painless and reducible
- skin stretching, tenderness or difficulty with clothing if the hernia enlarges
- severe pain, vomiting, colour change or bowel blockage symptoms if the hernia becomes trapped
Causes and mechanism
The umbilicus is a natural weak point where the umbilical cord passed through the abdominal wall before birth. In babies, the ring of muscle may not close fully straight away, allowing bowel or fat to bulge through when pressure rises. In adults, the weakness may develop or widen because of repeated pressure on the abdominal wall. The hernia sac can contain fat or bowel. If the contents slide back easily, the hernia is reducible; if they become stuck, blood supply and bowel passage may be threatened.
Risk factors
Risk factors do not mean someone will definitely develop the condition, and absence of risk factors does not rule it out. They help guide assessment and prevention conversations.
- infancy, especially when the umbilical ring has not fully closed
- multiple pregnancies, abdominal wall stretching or previous abdominal surgery
- living with obesity or rapid changes in abdominal pressure
- ascites from liver disease or another cause of abdominal fluid
- chronic cough, constipation or repeated heavy lifting that increases strain
Possible complications
Umbilical hernia complications are uncommon in children but can happen, especially in adults. Incarceration means the contents become stuck. Strangulation means blood supply is cut off, which can lead to bowel damage, sepsis or gangrene and needs emergency surgery. A hernia can also enlarge, become painful or recur after repair. Surgery carries risks such as infection, bleeding, blood clots, long-lasting pain and recurrence, so adult repair decisions should consider hernia size, symptoms, surgical fitness and personal priorities.
Diagnosis and assessment
A clinician usually diagnoses an umbilical hernia by examining the abdomen while the person is lying and standing, and sometimes while coughing or straining. They assess size, tenderness, whether the lump reduces and whether symptoms suggest bowel obstruction. Ultrasound or other imaging may be used if the diagnosis is uncertain, if there are multiple abdominal wall defects, or if symptoms do not match the examination. Babies and children should be reviewed by a GP or paediatric clinician rather than treated with taping or pressure devices.
Treatment and management
Children often do not need treatment because many umbilical hernias close as the child grows. Surgery may be considered if a child has a very large hernia, persistent hernia or complications. Adults are more often offered surgical repair because spontaneous closure is unlikely. Repair usually involves pushing the hernia back and closing the muscle gap; larger defects may need mesh reinforcement. People with serious liver disease, ascites or other health risks need careful specialist planning before surgery.
Assessment details that change care
For Umbilical hernia, the details that most often change care are not just whether a symptom is present, but how quickly it started, whether it is worsening, whether it is recurrent, and whether it appears with other warning signs. A clinician will usually want to know about features such as a soft lump or swelling at the belly button that may enlarge when coughing, crying or straining; discomfort, pressure or aching around the navel, especially in adults; a bulge that may be pushed back gently when painless and reducible. They will also ask about context, including infancy, especially when the umbilical ring has not fully closed; multiple pregnancies, abdominal wall stretching or previous abdominal surgery; living with obesity or rapid changes in abdominal pressure. This is why a concise symptom diary can be useful: note the date symptoms started, what makes them better or worse, medicines already tried, pregnancy or menopause context where relevant, immune suppression, recent surgery or travel, and whether the problem is affecting sleep, eating, urination, sex, movement or work.
Severity is judged by combining symptoms, examination findings, risk factors and test results. A mild-looking symptom can matter more if it is new, escalating, associated with fever or systemic illness, or happening in a baby, pregnancy, older age or immune suppression. Equally, a visible lump, rash, blister or blood-test result may be less urgent when it is stable and the person is otherwise well. The safest approach is to avoid forcing the condition into a home diagnosis. Assessment-first language is especially important for Umbilical hernia because treatment choices may differ according to anatomy, infection risk, recurrence pattern, underlying disease and personal circumstances.
Before an appointment, useful questions include: What diagnosis is most likely and what else needs to be ruled out? Which symptoms should trigger same-day help? Are tests needed now or only if symptoms persist? What treatment options are reasonable, what benefits are expected, and what limitations or side effects should be discussed? Are there activities, sex, contact lenses, exercise, lifting, pregnancy plans, baby contact or medicines that should be paused until review? This kind of practical planning helps turn a general article into safer, more useful health information.
Self-care and prevention
Do not bind, tape or coin a baby’s hernia, as this can irritate skin and does not repair the muscle. Adults can reduce strain by treating constipation, avoiding heavy lifting that worsens symptoms, getting support for chronic cough and discussing weight or ascites management where relevant. During pregnancy or after birth, assessment can distinguish hernia from diastasis recti and guide safe activity. Support garments may help comfort for some people but do not close the defect.
When to seek medical advice
Call 999 if an umbilical hernia is associated with very bad tummy pain that does not go away, vomiting, inability to keep food down, increased swelling with skin colour change, or inability to pass wind or poo. Use NHS 111 for urgent advice if pain is increasing, the lump becomes hard or tender, or there is fever. See a GP for any suspected umbilical hernia in a child or adult.
