Some symptoms of hernias include obvious swelling in the abdomen or groin area, constipation, and discomfort in the abdomen or groin while lifting or bending, explains WebMD. A ruptured hernia is not listed as a hernia complication, according to Mayo Clinic.
Different types of hernias have varying symptoms. The four most-common types of hernias are inguinal, hiatial, umbilical and incisional, according to WebMD. Many people with hiatial hernias do not experience any symptoms. However, some report heartburn or chest pains. Symptoms of umbilical hernias include a bulge when the baby cries or coughs and mild discomfort.
Inguinal hernias are known to grow over time if not treated, says Mayo Clinic. This can cause pressure on the surrounding tissue and in some cases with men, large inguinal hernias extend into the scrotum causing further pain and swelling. Two other complications possible with inguinal hernias include incarceration and strangulation. An incarcerated hernia happens when a loop of intestine becomes trapped in the abdominal wall. This obstructs the bowel and causes severe pain, nausea, vomiting and constipation.
Sometimes incarcerated hernias cut off blood flow to the intestine resulting in strangulation. This is a life-threatening situation that requires immediate medical attention, warns Mayo Clinic.
