Hernias are conditions where part of an organ or tissue protrudes through a weak spot in the surrounding muscle or connective tissue into another area of the body. The most common types are inguinal hernias, which occur in the groin area, and umbilical hernias, which develop around the belly button. Hernias can be painful and lead to other complications if left untreated. They are often aggravated by physical exertion, obesity, or a genetic predisposition. Diagnosis is typically made through a physical examination, and imaging techniques such as ultrasound or MRI can help determine the size and exact location of the hernia. In many cases, surgical treatment is necessary to repair the protruding tissue and reduce the risk of complications.
