An underactive thyroid occurs with the thyroid doesn't produce enough thyroid hormones. This is most commonly referred to as hypothyroidism. An underactive thyroid also occurs due to Hashimoto's thyroiditis (a thyroid autoimmune condition) as well as postpartum thyrioditis. Thyroid conditions are hereditary in nature, especially among women.
Graves disease.
The disease that is associated with excessive amounts of thyroid hormones is hyperthyroidism. Hyperthyroidism is a thyroid condition that causes the thyroid to become overactive. An overactive thyroid produces too much thyroid stimulating hormones.
Graves disease, hyperthyroidism
No. Graves' disease is an autoimmune disease that causes a overactive thyroid gland.
Hashimoto's causes inflammation of the thyroid gland. It also causes the thyroid gland to become underactive, or hypothyroid
Causes of premature menopause include autoimmune disorders (thyroid disease or diabetes mellitus), cancer treatments (chemotherapy or radiation), surgery to remove ovaries.

Graves' Disease.
Thyromegaly with diffuse parenchymal disease is a disease of the thyroid that causes goiter. Thyromegaly with diffuse parenchymal disease affects the functioning of the thyroid with many abnormalities.
Grave's disease is an autoimmune disease which causes hyperthyroidism.(particularly in the developed countries). normally TSH combines with the surface receptors of thyroid cells and causes the synthesis and secretion of thyroid hormones. in Grave's disease the thyroid stimulating autoantibodies (B-TSAB) produced by B lymphocytes activate the TSH receptors and increase the secretion of thyroid hormones(thyroxine and triiodothyronine). Grave's disease is due to elevated thyroid stimulating IgG also knoen as long acting thyroid stimulator (LATS) which activates TSH and, thereby, increases thyroid hormonal production.
When the immune system attacks the thyroid tissue, Hashimoto's thyroiditis or Graves' disease can develop. While both conditions are classified as thyroid autoimmune diseases, they have different symptoms and treatments.
An under-active thyroid is a condition in which your thyroid gland doesn't produce enough of certain important hormones. It seldom causes symptoms in the early stages, but, over time, untreated hypothyroidism can cause a number of health problems, such as depression, severe fatigue, obesity, joint pain, infertility and heart disease.
