Hernia

Also known as: Inguinal Hernia, Hiatal Hernia, Umbilical Hernia

A hernia occurs when an organ or tissue pushes through a weak spot in the surrounding muscle or connective tissue. Common types include inguinal (groin), hiatal (upper stomach), umbilical (belly button), and incisional hernias. Surgical repair is often needed to prevent serious complications like strangulation.

Symptoms

Visible bulge in the groin, abdomen, or belly button area
Pain or discomfort when bending, coughing, or lifting
Aching or burning sensation at the hernia site
Feeling of heaviness in the groin
Heartburn or difficulty swallowing (hiatal hernia)
Nausea, vomiting, and inability to pass gas (signs of incarceration)

Causes

  • Weakness in the abdominal wall (congenital or acquired)
  • Increased abdominal pressure from lifting, coughing, or straining
  • Previous surgical incision weakening the wall
  • Connective tissue disorders

Risk Factors

  • Male sex (inguinal hernias much more common in men)
  • Older age
  • Chronic cough or constipation
  • Pregnancy
  • Obesity
  • Previous hernia or hernia repair

Diagnosis

  • Physical examination
  • Ultrasound of the abdominal wall
  • CT scan to assess size, contents, and complications
  • Upper endoscopy or barium swallow for hiatal hernias

Treatment

  • Watchful waiting for small, asymptomatic hernias
  • Open surgical repair with mesh reinforcement
  • Laparoscopic or robotic hernia repair
  • Emergency surgery for incarcerated or strangulated hernias
  • Lifestyle modifications and weight management

Prevention

  • Maintain a healthy weight
  • Use proper lifting techniques
  • Treat chronic cough and constipation
  • Strengthen abdominal muscles with appropriate exercise

When to See a Doctor

  • A hernia becomes painful, grows larger, or cannot be pushed back in
  • You experience nausea, vomiting, or inability to pass gas with a known hernia
  • The skin over the hernia becomes red or discolored
  • You notice a new bulge in the groin or abdomen
