What is inguinal hernia ?
An inguinal hernia is a condition in which intra-abdominal fat or part of the small intestine, also called the small bowel, bulges through a weak area in the lower abdominal muscles. An inguinal hernia occurs in the groin-the area between the abdomen and thigh. This type of hernia is called inguinal because fat or part of the intestine slides through a weak area at the inguinal ring, the opening to the inguinal canal. An inguinal hernia appears as a bulge on one or both sides of the groin. An inguinal hernia can occur any time from infancy to adulthood and is much more common in males than females. Inguinal hernias tend to become larger with time.
What are the types and causes of inguinal hernia ?
The two types of inguinal hernia have different causes.
Indirect inguinal hernia : – Indirect inguinal hernias are congenital hernias and are much more common in males than females because of the way males develop in the womb. In a male fetus, the spermatic cord and both testicles-starting from an intra-abdominal location-normally descend through the inguinal canal into the scrotum, the sac that holds the testicles. Sometimes the entrance of the inguinal canal at the inguinal ring does not close as it should just after birth, leaving a weakness in the abdominal wall. Fat or part of the small intestine slides through the weakness into the inguinal canal, causing a hernia. In females, an indirect inguinal hernia is caused by the female organs or the small intestine sliding into the groin through a weakness in the abdominal wall.
Indirect hernias are the most common type of inguinal hernia. Premature infants are especially at risk for indirect inguinal hernias because there is less time for the inguinal canal to close.
Direct Inguinal Hernia : – Direct inguinal hernias are caused by connective tissue degeneration of the abdominal muscles, which causes weakening of the muscles during the adult years. Direct inguinal hernias occur only in males. The hernia involves fat or the small intestine sliding through the weak muscles into the groin. A direct hernia develops gradually because of continuous stress on the muscles. One or more of the following factors can cause pressure on the abdominal muscles and may worsen the hernia:
o sudden twists, pulls, or muscle strains
o lifting heavy objects
o straining on the toilet because of constipation
o weight gain
o chronic coughing
Indirect and direct inguinal hernias usually slide back and forth spontaneously through the inguinal canal and can often be moved back into the abdomen with gentle massage.
What are the symptoms of inguinal hernia ?
Symptoms of inguinal hernia include : –
* a small bulge in one or both sides of the groin that may increase in size and disappear when lying down; in males, it can present as a swollen or enlarged scrotum
* discomfort or sharp pain-especially when straining, lifting, or exercising-that improves when resting
* a feeling of weakness or pressure in the groin
* a burning, gurgling, or aching feeling at the bulge
What are “incarcerated” and “strangulated” inguinal hernias ?
An incarcerated inguinal hernia is a hernia that becomes stuck in the groin or scrotum and cannot be massaged back into the abdomen. An incarcerated hernia is caused by swelling and can lead to a strangulated hernia, in which the blood supply to the incarcerated small intestine is jeopardized. A strangulated hernia is a serious condition and requires immediate medical attention.
Symptoms of a strangulated hernia include : –
* extreme tenderness and redness in the area of the bulge
* sudden pain that worsens in a short period of time
* rapid heart rate
Left untreated, nausea, vomiting, and severe infection can occur. If surgery is not performed right away, the condition can become life threatening, and the affected intestine may die. Then that portion of the intestine must be removed.
