Hernia: A hernia results when the contents of a body cavity bulge out of their normal area. There are many types of hernia, including inguinal, femoral, umbilical, incisional, Spigelian, obturator, and epigastric hernias. Hernias may be caused by coughing, obesity, heavy lifting, straining, fluid in the abdominal cavity, or chronic lung disease. Symptoms and signs include a lump or bulge, pain, and possible fever. Hernias are generally surgically repaired.
Obesity More than two-thirds of Americans are overweight, including at least one in five children. Nearly one-third are obese. Obesity is on the rise in our society because food is abundant and physical activity is optional. The safest way to lose weight is to eat less and exercise more. Treatment may also include medications, surgery, and behavior modification.
