Pseudohypothyroidism. Differentiation from true hypothyroidism.
Pseudohypothyroidism is a prevalent "non-disease" that represents an erroneous diagnosis of hypothyroidism. The error in diagnosis can be readily recognized, and unnecessary therapy with thyroid hormones--which are ineffective and potentially can induce harmful side effects--can be terminated. By recognizing that hypothyroidism is not the cause of the patient's complaints, the physician can pursue further investigation to elucidate the true cause.
