Birth Defects

A birth defect is a problem that happens while a baby is developing in the mother's body. Most birth defects happen during the first 3 months of pregnancy. One out of every 33 babies in the United States is born with a birth defect.

A birth defect may affect how the body looks, works or both. Some birth defects like cleft lip or neural tube defects are structural problems that can be easy to see. To find others, like heart defects, doctors use special tests. Birth defects can range from mild to severe. Causes can include

  • Genetics
  • Exposures to medicines or chemicals. For example, alcohol abuse can cause fetal alcohol syndrome.
  • Infections during pregnancy
  • Certain medicines. Before you get pregnant, talk to your health care provider about any medicines you take.
  • Not getting enough of certain nutrients. For example, not getting enough folic acid before and during pregnancy is a key factor in causing neural tube defects.

For most birth defects, the cause is unknown.

Health care providers can diagnose certain birth defects during pregnancy, with prenatal tests. That's why it important to get regular prenatal care. Other birth defects may not be found until after the baby is born. Sometimes the defect is obvious right away. Other times, the health care provider may not discover it until later in life.

Babies with birth defects often need special care and treatments. The treatments may include surgery, medicines, assistive devices, and therapies.

Salivary Gland Disorders

Your salivary glands are in your mouth. You have three pairs of major salivary glands and hundreds of small (minor) glands. They make saliva (spit) and empty it into your mouth through openings called ducts. Saliva makes your food moist, which helps you chew and swallow. It helps you digest your food. It also cleans your mouth and contains antibodies that can kill germs.

Problems with salivary glands can cause them to become irritated and swollen. You may have symptoms such as

  • A bad taste in your mouth
  • Difficulty opening your mouth
  • Dry mouth
  • Pain in your face or mouth
  • Swelling of your face or neck

Causes of salivary gland problems include infections, obstruction, or cancer. Problems can also be due to other disorders, such as mumps or Sjogren's syndrome.
