What Is an Inguinal Hernia?
An inguinal hernia occurs when internal tissue—such as intra-abdominal fat or a portion of the intestine—pushes through a localized area of weakness in the lower abdominal muscles into the inguinal canal. The inguinal canal is a natural passage in the groin area.
Inguinal hernias generally fall into two anatomical categories:
- Indirect Inguinal Hernia: Often related to a congenital opening at the internal inguinal ring that did not fully close before birth, allowing abdominal contents to follow the path of the spermatic cord.
- Direct Inguinal Hernia: Typically develops over time as abdominal wall muscles weaken through age, persistent physical strain, chronic coughing, or heavy lifting, creating a bulge directly through the floor of the inguinal canal.
Patients typically notice a soft bulge in the groin that may become more noticeable when standing, coughing, or exercising. A clinical physical examination by a surgeon is the primary method for diagnosing an inguinal hernia. Imaging, such as an ultrasound, is used when clinically indicated to evaluate ambiguous cases or confirm anatomical details.
