The
thyroid makes hormones that help your body work. If it makes too little or too much of these hormones, you may have problems during pregnancy.
Untreated thyroid conditions during pregnancy are linked to serious problems, including premature birth, miscarriage and stillbirth.
If your thyroid condition is treated during pregnancy, you can have a healthy pregnancy and a healthy baby.
Severe and prolonged hypothyroidism and hyperthyroidism can cause loss of hair. The loss is diffuse and involves the entire scalp rather than discrete areas. The hair appears uniformly sparse. Regrowth is usual with successful treatment of the thyroid disorder, though it will take several months and may be incomplete.
