Women with these factors should have their thyroid checked before pregnancy, or within the first weeks of pregnancy, and should be retested during each trimester.
Screening in Infants. In the U.S., most newborns are routinely screened for hypothyroidism using a thyroid blood test.
Ruling out Other Disorders
Hypothyroidism can mimic other medical conditions.
Age-Related Disorders. Some symptoms of hypothyroidism and aging are very similar. Menopausal symptoms often resemble hypothyroidism. Many other problems related to aging -- such as vitamin deficiencies, Parkinson's and Alzheimer's diseases, and arthritis -- also have characteristics that can mimic hypothyroidism.
Depression. Drowsiness, fatigue, and difficulty concentrating are signs of clinical depression as well as hypothyroidism. The two disorders often coexist, particularly in older women, so diagnosing one does not rule out the presence of the other.
Diseases of Muscles and Joints. Joint and muscle aches may be initial symptoms of hypothyroidism. Most likely, however, such pain is not caused by hypothyroidism if other thyroid symptoms remain absent. Numerous conditions can cause muscle and joint pain, and if thyroid levels are normal the doctor should look for other causes.
