High thyroid stimulating hormone (TSH) during pregnancy may be due to physiologic or pathologic factors. When clinical symptoms appear, drug treatment under medical supervision is recommended.
1. Physiological factors: due to the effect of hCG, the upper and lower limits of the serum TSH reference range in early pregnancy will show different degrees of decline, and the lower limit of TSH in a few pregnant women is even lower than the detectable level (<0.01mU/L). Serum TSH gradually rises in mid-pregnancy and may even be higher than in the general population in late pregnancy.
If TSH is high due to physiologic factors, usually no treatment is needed, and daily attention should be paid to monitoring thyroid function.
2. Pathological factors: high TSH accompanied by symptoms such as fatigue and chills may be considered as hypothyroidism. If hypothyroidism is diagnosed, hormone replacement therapy such as oral thyroxine tablets can be prescribed.
It is recommended that patients with high thyroid stimulating hormone during pregnancy should go to regular hospitals for timely consultation, complete relevant examinations, and standardize the treatment under the guidance of doctors to avoid delaying the condition or causing adverse reactions.
