SYMPTOMS OF HYPOTHYROIDISM

  1. ACTION ON CENTRAL NERVOUS SYSTEM

    central nervous system (Hypothyroidism)

    This hormone stimulate brain and increases flow of blood to brain.It also helps us for normal sleep pattern.It also required for growth and development of brain during fetal life and postnatal life.So,when this hormone level decreases, it causes symptoms like

 If there is any doubt regarding body weight than it will be clear here in fat metabolism.Thyroxine convert fat into free fatty acid and transported to blood.

When thyroid hormone is not sufficient than it can not convert fat into free fatty acids properly.Which increases fat storage and so weight gain in hypothyroidism.
