Hyperthyroidism and pregnancy identification
hyperthyroidism of hyperemesis gravidarum distinguished. 8 to 14 weeks of pregnancy, hCG stimulates the thyroid gland as FT4, FT3 increased, TSH can be showed moderate inhibition, but TSH is not less than 0.1mU / L, TSAb-negative, then the tips hyperthyroidism of hyperemesis gravidarum.
hyperthyroidism in pregnancy secondary inspection
1. pregnant women suspected of having hyperthyroidism, thyroid function tests should be promptly checked. the vast majority of patients with hyperthyroidism FT4, FT4I increased and TSH decreased in patients with subclinical hyperthyroidism individual FT4 in the normal range or normal range, the need to measure TSH,
TSH can certainly reduce the determination of diagnostic
2.TSHRAb (refer to TSI), for Graves’ disease patients have important reference value, such as:
(1) over the last pregnancy, childbirth and fetal or neonatal hyperthyroidism;
(2) active hyperthyroidism, is using the ATD treatment;
(3) hyperthyroidism been or are being eased, now has normal thyroid function, but fetal tachycardia;
(4) fetal growth restriction;
(5) ultrasound to determine fetal goiter if TSHRAb increase indicates that the fetus or newborn hyperthyroidism.
3. caused by a variety of different causes of hyperthyroidism, in laboratory tests and clinical characteristics of the various tools, such as Graves disease, clinically exophthalmos, checks can be found in the serum Pok TSI.
subacute thyroiditis patients, in addition to the common features of hyperthyroidism, there are fever, fatigue, sweating, chills and other symptoms normal complete blood count, erythrocyte sedimentation rate was accelerated. The disease mostly occurs in spring and autumn, often accompanied by pharyngitis thyroiditis , mumps and respiratory tract infections, mild thyroid enlargement, local tenderness subacute thyroiditis with transient hyperthyroidism, and more without anti-thyroid drug treatment.
4. Chronic lymphocytic thyroiditis caused by hyperthyroidism, seen in the early stages of the disease, late into the disease hypothyroidism, thyroid texture and tough. Pok examination revealed serum anti-thyroid antibody levels, including cones antibody and peroxidase antibody.
5. trophoblastic disease There are primary disease characteristics, elevated serum b HCG is an important symbol, hyperthyroidism is associated with symptoms.
6. Serum calcium and alkaline phosphorus acid enzymes, about 10% to 27% increase in serum calcium in patients with hyperthyroidism, the source in bone loss, even thou there is hyperthyroidism caused by hyperparathyroidism.
pregnancy do not check the Thyroid 131 Ⅰ past application of basal metabolic rate (BMR), BMR increased in patients with hyperthyroidism, but the quasi- correct rate of only 50%.
