During a physical examination for a hernia, the doctor should always have you stand up. While the he or she gently probes the swollen area, you'll be asked to cough, strain, or perform a movement to the best of your ability.  The doctor will evaluate the flexibility and movement in the area where a hernia is suspected. After assessment, he or she will be able to diagnose whether you have one, and what type of hernia you may have. This is the most common type of hernia, and happens when the intestines or bladder push the lower abdominal wall into the groin and inguinal canal. In men, this canal holds chords that connect to the testicles, and hernias are usually caused by a natural weakness in the canal. In women, the canal holds ligaments that keep the uterus in place. There are two types of inguinal hernia: direct and, more commonly, indirect.  Direct inguinal hernia: Place your finger on the inguinal canal — the crease along the pelvis where it meets the legs. You will feel a bulge that pops out toward the front of the body, and coughing will make the larger. Indirect inguinal hernia: When you touch the inguinal canal, you will feel a bulge going from outside towards the center of your body (lateral to medial).  This bulge may also move down towards the scrotum. Hiatal hernias happen when the upper part of your stomach pushes through the opening of the diaphragm, and into the chest. This type of hernia usually happens in people over 50 years old, though. If a child has a hiatal hernia, it's likely because of a birth defect.  The diaphragm is a thin sheet of muscle that helps you breathe. It's also the muscle responsible for separating the organs in the abdomen and in the chest. This kind of hernia causes burning sensations in the stomach, chest pain, and difficulty swallowing Though they can occur later in life, umbilical hernias commonly occur in newborns or babies less than 6 months old. They happen when intestines push out in the abdominal wall near the belly button or the navel. The bulge is especially noticeable when the child is crying.  With umbilical hernias, you will see a bulge at the "umbilicus," or belly button. Umbilical hernias usually go away on their own. But, if it lasts until the child is 5 to 6 years old, is very large or is causing symptoms, the hernia may need surgery.  Take note of the size; small umbilical hernias, around half an inch (1.25cm), can go away on their own. Large umbilical hernias require surgery. The incisions (cuts) performed during surgery take time to heal and scar over properly. It also takes time for the surrounding muscles to regain their strength. If organ tissue pushes out through the incision scar before it's healed, an incisional hernia occurs. It's most common in elderly and overweight patients. Place gentle but firm pressure near the surgical site with your fingers. You should feel a bulge somewhere in the area. While femoral hernias can happen to both men and women, the vast majority of cases occur in women because of their wider pelvic shape. In the pelvis, there's a canal that carries arteries, veins and nerves into the upper-inner thigh. This canal is normally a tight space, but it often becomes larger if the woman is pregnant or obese. When it stretches out, it becomes weak, and thus vulnerable to potential hernias.

Summary:
Understand how doctors diagnose hernias. Recognize an inguinal hernia. Suspect a hiatal hernia in people over 50. Look for umbilical hernias in babies. Be careful of incisional hernia after surgery. Recognize a femoral hernia in women.
