hypothyroid causes

There are a bunch of hypothyroid causes that people should know. Hypothyroidism can also be due to the absence of brain hormones. Usually, this happens when the hypothalamus or the pituitary gland fails to secrete hormones due to an infection or trauma. Occasionally it could also be caused by infiltration which is extremely common to cancer patients who need their brain tissues to get replaced by new ones. In special cases, the removal of the thyroid gland as a result of an infection or cancer, may at last increase the likelihood of a person developing hypothyroidism in the future.
