Graves Disease refers to an autoimmune disorder leading to the over-activeness of the thyroid gland (or hyperthyroidism), a key organ of the endocrine system, situated at the front of the neck just beneath the voice box. The thyroid gland produces thyroid hormones like thryoxine (T4) and triiodothyronine (T3) that controls the metabolism of the human body. The control of metabolism is important for the regulation of body weight, mood, and physical and mental energy levels. It is mostly found in women above 20 years of age. Common symptoms include anxiety, double vision, breast enlargement, eye irritation, fatigue, goiter, frequent bowel movements, tremor, weight loss, insomnia, muscle weakness, nervousness, and shortness of breath.
