An umbilical hernia is a bulge at or just above the belly button caused by a weakness in the abdominal wall around the umbilical scar — the same point where, before birth, the umbilical cord passed through. In babies, small umbilical hernias are extremely common and most close spontaneously by age 3–4. In adults, umbilical hernias do not heal on their own and tend to enlarge slowly over years. They are particularly common after pregnancy, with weight gain, in patients with chronic cough or constipation, and in those with previous abdominal surgery. Dr. Vanesha Varik is a female specialist general surgeon at Medcare Hospital Al Safa, Dubai, who treats adult umbilical and paraumbilical hernias using both open suture, open mesh and laparoscopic techniques. This guide explains everything you need to know about umbilical hernia in Dubai — from causes to recovery.
What is an umbilical hernia?
An umbilical hernia occurs when fatty tissue, omentum or a portion of bowel pushes through a defect in the linea alba (the central tendon of the abdominal wall) at or just above the umbilicus. The classic sign is a soft bulge at the belly button that becomes more visible with standing, coughing or straining.
A paraumbilical hernia is essentially the same condition but the defect is just above (or occasionally just below) the umbilicus rather than directly through it. They are managed identically.
Causes and risk factors
Adult umbilical hernias develop where the abdominal wall is intrinsically weak. Common contributing factors include:
- •Pregnancy (especially multiple pregnancies)
- •Significant weight gain or obesity
- •Chronic cough or asthma
- •Chronic constipation or straining
- •Heavy lifting at work or in the gym
- •Previous open abdominal surgery (laparotomy, caesarean)
- •Ascites (fluid in the abdomen) from liver disease
Symptoms in adults
- •Soft bulge at or just above the belly button
- •Bulge becomes more obvious with standing, coughing, lifting or straining
- •Dull ache or burning sensation, worse at the end of the day
- •Bulge may disappear when lying down
- •Skin over the hernia may stretch and become discoloured if the hernia is large
Sudden severe pain, a hard tender lump, vomiting or skin redness are emergency signs of strangulation — go to A&E immediately.
Umbilical hernia in babies and children
Up to 1 in 5 babies have a small umbilical hernia at birth. In most cases the defect closes spontaneously by age 3–4 with no treatment.
Surgical referral is recommended if: the defect is greater than 1.5 cm, the hernia persists beyond age 4, the hernia is symptomatic (very rare), or the child develops any signs of strangulation.
Dr. Vanesha Varik treats adult patients only — paediatric umbilical hernias are managed by paediatric surgeons.
Why adult umbilical hernias should usually be repaired
Adult umbilical hernias do not heal spontaneously. They tend to enlarge slowly over years and the neck of the defect can be tight, giving them a higher per-year strangulation risk than larger inguinal hernias.
Elective repair is straightforward, day-care surgery in most cases. Emergency repair after strangulation is significantly more complex and may require bowel resection.
How umbilical hernia is repaired
Repair technique depends on the size of the defect:
- •Defects under 1 cm: open suture repair under local or general anaesthesia. Quick, simple, low recurrence.
- •Defects 1–4 cm: open mesh repair (Ventralex or similar) — small incision, mesh placed behind the muscle wall. Standard approach.
- •Defects over 4 cm or recurrent: laparoscopic IPOM (Intra-Peritoneal Onlay Mesh) repair — three small incisions, dual-sided mesh placed inside the abdominal cavity.
Cosmetic restoration of the belly button is part of all modern umbilical hernia repairs at Medcare Hospital.
Recovery after umbilical hernia repair
Most patients are discharged the same day. Mild bruising and swelling around the belly button is normal for 1–2 weeks.
Typical milestones: walking the same day, desk work in 5–7 days, driving at 7–10 days, gym at 2–3 weeks (light) and full activity at 4–6 weeks.
Special considerations after pregnancy
Many women develop umbilical hernias during pregnancy. We generally advise: complete your family before elective repair, ideally repair 6–12 months after the last delivery, and address any associated diastasis recti at the same operation if appropriate.
A female surgeon may be preferred for examination and discussion of postpartum body changes.
