Subclinical hyperthyroidism in pregnancy is associated with an increased risk of pre-eclampsia, low birth weight, miscarriage and preterm birth. [50] Propylthiouracil is the preferred treatment of hyperthyroidism (both overt and subclinical) in the first trimester of pregnancy as it is associated with less birth defects than methimazole. [50]
Graves' ophthalmopathy, also known as thyroid eye disease (TED), is an autoimmune inflammatory disorder of the orbit and periorbital tissues, characterized by upper eyelid retraction, lid lag, swelling, redness (), conjunctivitis, and bulging eyes (exophthalmos). [1]
Normal thyroid levels are also seen, and occasionally also hypothyroidism, which may assist in causing goiter (though it is not the cause of the Graves' disease). Hyperthyroidism in Graves' disease is confirmed, as with any other cause of hyperthyroidism, by measuring elevated blood levels of free (unbound) T3 and T4. [citation needed]
Thyroid diseases are highly prevalent worldwide, [10] [11] [12] and treatment varies based on the disorder. Levothyroxine is the mainstay of treatment for people with hypothyroidism, [13] while people with hyperthyroidism caused by Graves' disease can be managed with iodine therapy, antithyroid medication, or surgical removal of the thyroid ...
Exophthalmos (also called exophthalmus, exophthalmia, proptosis, or exorbitism) is a bulging of the eye anteriorly out of the orbit. Exophthalmos can be either bilateral (as is often seen in Graves' disease) or unilateral (as is often seen in an orbital tumor). Complete or partial dislocation from the orbit is also possible from trauma or ...
Infiltrative ophthalmopathy is found in 5-10% of patients with Graves disease and resembles exophthalmos, except that the blurry or double vision is acquired because of weakness in the ocular muscles of the eye. [1] [2] In addition, there is no known correlation with the patient's thyroid levels.
Hyperthyroidism may be asymptomatic or present with significant symptoms. [2] Some of the symptoms of hyperthyroidism include nervousness, irritability, increased perspiration, heart racing, hand tremors, anxiety, trouble sleeping, thinning of the skin, fine brittle hair, and muscular weakness—especially in the upper arms and thighs.
