The thyroid is an important organ that plays a role in releasing hormones, shaped like a butterfly in the front of the neck. Although this is a very small gland, it is an important organ and is easily invaded, leading to inflammation, affecting the patient's health. Through many studies, the rate of thyroid disease is about 30% in people aged 18-65, the rate of disease increases with age and is more common in women (ratio of 5 women / 1 man). Thyroid diseases are often overlooked and undiagnosed in 20-60% of all people with the disease. This makes examination and treatment more difficult, many people when discovered the disease has progressed to a more severe stage.
