No hernia of the abdominal wall is more common than the inguinal hernia, also known as a groin hernia. In the area of the inguinal canal, the abdominal wall gives way and the peritoneum pushes outwards through the gap – the hernial orifice – often followed by fatty tissue, sometimes by a loop of bowel. Men are affected much more often than women: in men, the spermatic cord runs through the inguinal canal, which therefore forms a natural weak point.
A typical sign is a soft swelling that becomes more noticeable when standing, coughing or straining and often recedes when lying down. Many people feel a pulling or pressing sensation that increases with exertion, and a feeling of heaviness towards the evening; in men, the discomfort can radiate into the scrotum. Some hernias go unnoticed for a long time and are only discovered during an examination.
An inguinal hernia cannot regress; if anything, it gets bigger over time. Even so, not every hernia has to be operated on straight away: the international HerniaSurge guideline, endorsed by the German Hernia Society, explicitly names watchful waiting as an option when symptoms are absent or mild. If the hernia limits you at work, during sport or in everyday life, that speaks in favour of surgery – at an early stage, the procedure is usually smaller.
Women have a femoral hernia more often than men; it emerges just below the inguinal ligament. Its hernial orifice is narrow, and tissue becomes trapped there more easily. In women, a swelling in the groin region should therefore be checked promptly.
