Women with symptoms or a very high TSH level, or both, are usually prescribed a course of levothyroxine. [3] Asymptomatic women with slightly elevated TSH levels who are planning subsequent pregnancies, should consider a course of treatment until completion of the family to avoid possible developmental complications in future children.

Thyroid hormone concentrations in blood are increased in pregnancy, partly due to the high levels of estrogen and due to the weak thyroid stimulating effects of human chorionic gonadotropin (hCG) that acts like TSH. Thyroxine (T4) levels rise from about 6–12 weeks, and peak by mid-gestation; reverse changes are seen with TSH.
Autoimmune hypophysitis can lead to deficiencies in one or more pituitary hormones, causing central diabetes insipidus if the posterior pituitary gland is affected as well as central adrenal insufficiency and central hypothyroidism if the anterior pituitary gland is affected. [1] The symptoms depend on what part of the pituitary is affected.
Both NTIS and primary hypothyroidism may have reduced fT3 and fT4, and elevated TSH (which is common in the hospital, during the recovery phase of NTIS). [2] Prescribing thyroxine to treat this may lead to lifelong thyroid overtreatment. [2] Hyperthyroidism may be assumed due to decreased TSH and a transient fT4 increase.
Gestational diabetes is when a woman, without a previous diagnosis of diabetes, develops high blood sugar levels during pregnancy. [13] [14] There are many non-modifiable and modifiable risk factors that lead to the devopment of this complication. Non-modifiable risk factors include a family history of diabetes, advanced maternal age, and ...
Subclinical hypothyroidism, a milder form of hypothyroidism characterized by normal thyroxine levels and an elevated TSH level, is thought to occur in 4.3–8.5% of people in the United States. [8] Subclinical hypothyroidism has been associated with an increased risk of atrial fibrillation (AF) and is the most frequent thyroid abnormality in ...
The negative effects of pregestational diabetes are due to high blood sugar and insulin levels primarily during the first trimester of pregnancy (in contrast to gestational diabetes, which can lead to fetal complications during the second and third trimester). Since this period is when many of the major internal structures and organs of the ...
Central diabetes insipidus, recently renamed arginine vasopressin deficiency (AVP-D), [1] is a form of diabetes insipidus that is due to a lack of vasopressin (ADH) production in the brain. Vasopressin acts to increase the volume of blood (intravascularly), and decrease the volume of urine produced.
