What Are Hernias?
A hernia occurs when an internal organ or tissue pushes through a weakened spot in the surrounding muscle or connective tissue. The most common site for hernias is the abdominal wall, although they can develop in other areas of the body as well.
Hernias typically appear as a visible lump, which may become more pronounced when straining, coughing, or lifting heavy objects. Left untreated, hernias can lead to serious complications, including strangulation of the protruding organ.
Common Types of Hernias
Hernias are categorised based on their location in the body. The most common types of hernias include:
- Inguinal Hernia: This occurs in the groin when tissue pushes through a weak spot in the lower abdominal wall.
- Femoral Hernia: This is found just below the groin and is more common in women.
- Umbilical Hernia: Seen around the belly button, this is usually found in infants but can also affect adults.
- Incisional Hernia: This develops at the site of a previous surgical incision.
- Hiatal Hernia: This involves the upper part of the stomach pushing into the chest cavity through the diaphragm.
- Epigastric Hernia: This develops in the upper abdominal wall, between the belly button and the lower part of the ribcage.
Risk Factors of Hernias
Factors that contribute to the development of hernias include:
- Physical Strain: Repeated heavy lifting, persistent coughing, or intense physical activity.
- Obesity: Extra abdominal pressure increases the risk of hernia development.
- Pregnancy: Increased pressure on the abdominal wall during pregnancy.
- Age: As muscles weaken with age, the risk of hernias increases.
- Family History: A genetic predisposition of having weak connective tissue can increase one’s risk.
- Previous Surgeries: Surgical incisions can leave weakened areas prone to hernias.
Signs and Symptoms of Hernias
Hernias may present with a variety of symptoms, including:
- A visible lump or bulge in the affected area, which may disappear when lying down
- Pain or discomfort, especially when bending, lifting, or coughing
- A feeling of heaviness or pressure in the abdomen or groin
- Nausea and vomiting in cases of strangulated hernias
- A burning or aching sensation at the site of the hernia
If a hernia becomes painful or the lump cannot be pushed back in, it may indicate strangulation which is a medical emergency that requires immediate attention.
