Thyroid is a butterfly shaped gland located on the front of the neck which can be palpated easily especially when it is swollen.

They both are involved in keeping the normal metabolic rate in body which requires energy by protein. Stimulation of these hormone is regulated by thyroid stimulating hormone TSH by pituitary gland.

As iodine is an important component of thyroid hormones and if it not sufficient then it can result in low-level of T3 or T4. This is actually present in iodized salt and some sea plants.
  • Furthermore,Hypothyroidism could also cause by some by birth defects in a baby. It is possible that baby have defective thyroid gland and it was made this way. This thing only results in low thyroid hormone. These kind of baby usually start to show symptoms in quite start like short stature and poor growth or development.
