TSH (Thyroid-stimulating hormone) levels affect the function of many of the body's organs including the heart, brain, liver, kidneys and skin. Untreated low thyroid function can contribute to high cholesterol levels, heart disease, infertility, muscle weakness and osteoporosis. Low thyroid function is relatively common in pregnancy affecting as many as five percent of pregnant women. If you are pregnant and have a low thyroid level, discuss this with your doctor and see what course of treatment (s)he would recommend. Good luck, Susu
