In the human body, we have a butterfly-shaped gland in the neck, called as the Thyroid gland. This gland makes the hormones, T3 and T4 which are necessary for the proper functioning of every organ in the body. Any disturbances in the functioning of this gland are reflected in the change in the level of another extremely sensitive hormone called TSH which comes from the pituitary gland. Hypothyroidism In hypothyroidism, T3, T4 hormones are low and TSH is high. A person might get symptoms of Fatigue Weight gain Drowsiness, lethargy Constipation Muscle weakness Goitre Memory disturbances Irregular periods/Infertility Hairloss etc When this hypothyroidism is a result of an autoimmune disease, it is called Hashimoto’s thyroiditis. This is often associated with Anti microsomal antibodies (or Anti TPO antibodies) or anti-thyroglobulin antibodies. Other varieties of thyroiditis include Subacute thyroiditis, postpartum thyroiditis, and Riedl’s thyroiditis. For the treatment of hypothyroidism, thyroxine sodium is given which is the T4 which our thyroid gland produces normally. So the treatment is simple and pure hormonal. There are no restrictions for food in hypothyroidism as is often misunderstood.
