Thyroid Disorders

The thyroid gland is located in the neck. It produces hormones that help control temperature, growth, behavior, blood pressure and heart rate.

The thyroid gland can become too active (hyperthyroidism) or not active enough (hypothyroidism). Treatments include medication, surgery, or radiation.

During pregnancy, you may need additional blood tests and ultrasound examinations if you have a thyroid disorder.

Increased risks for thyroid patients

  • Infertility is common with severe thyroid disorders.
  • Some treatments for thyroid disease cannot be used in pregnancy because they may harm the developing fetus.
  • Poorly controlled hypothyroidism may put your baby at risk for mental retardation and learning difficulties
  • Some forms of hyperthyroidism may put your baby at risk of growing slowly, developing hypothyroidism, and stillbirth.

Pregnancy's impact on thyroid disorders

  • Pregnant women and their unborn children tolerate mild and moderate thyroid disorders without significant health problems.
  • You may need to adjust your medication during pregnancy because of metabolism changes.
  • Some thyroid problems can get worse after your baby is born.
