Hypothyroidism and pregnancy loss: comparison with hyperthyroidism and diabetes in a Danish population‐based study

Abstract

Hypothyroidism increased the risk of both early and late pregnancy loss as did hyperthyroidism and in particular diabetes. We hypothesize that undetected or insufficiently treated maternal disease in the pregnancy may be of causal importance.

A hypothyroid mother after subtotal thyroidectomy delivered a newborn with hyperthyroidism from fetal stage: a case report

“…Previous studies have shown that untreated or even partially treated overt hyperthyroidism during pregnancy could increase the risk of pregnancy loss and fetal mortality [ 3 , 4 ]. Women diagnosed with hyperthyroidism should counsel the endocrinologist regarding plans for pregnancy and the adverse effects of both antithyroid drugs and LT4 during pregnancy [ 5 ].…”

Maternal hypothyroidism in the perinatal period and childhood asthma in the offspring

“…The ICD-8 codes were used to encode the diseases until 1994 when the ICD-10 codes were introduced. The following ICD codes were used to identify the main or auxiliary diagnosis of hypothyroidism (243.99-244.09 in ICD-8 codes; or E03 and E89.0 in ICD-10 codes) (25).…”

The influence of thyroid function disorders on pregnant women on the Apgar scale and psychomotor development of the child in the first 18 months of life

“…The main causes of hypothyroidism in pregnant women pertain to iodine deficiency and chronic lymphocytic Hashimoto's thyroiditis. Underlying hypothyroidism is also thyroidectomy, subtotal thyroidectomy, congenital hypothyroidism [2,5]. In the prenatal period, the function of thyroid is essentially modified.…”
