An incisional hernia occurs when tissue, often part of the intestine, pushes through a weak spot in the abdominal wall at the site of a previous surgical incision. This type of hernia can develop after surgeries such as appendectomy or cesarean section, where the abdominal muscles may not heal properly. Symptoms of an incisional hernia can include a noticeable bulge near the surgical site, discomfort, or pain, especially when lifting or straining. Treatment typically involves surgery to repair the hernia and strengthen the abdominal wall, preventing further complications.
