K40: Inguinal hernia

Inguinal hernias are a group of conditions that occur when tissue, such as part of the intestine, protrudes through a weak spot in the abdominal muscles. This often leads to a visible bulge in the groin area that can be painful, particularly when you cough, bend over, or lift a heavy object. The exact cause of inguinal hernias isn't always known, but they most commonly occur as a result of increased pressure in the abdomen, a pre-existing weak spot in the abdominal wall, or a combination of both. Inguinal hernias can also be congenital, meaning they are present at birth. They are more common in men than women. Symptoms of an inguinal hernia can include a bulge in the area on either side of your pubic bone, a burning or aching sensation at the bulge, pain or discomfort, especially when bending over, coughing, or lifting, and weakness or pressure in the groin. The condition can become more serious if the protruding abdominal tissue becomes trapped (incarcerated) or if the blood supply to the section of trapped intestine is cut off (strangulation), both of which are medical emergencies.
