EPIDEMIOLOGY OF AUTOIMMUNE THYROID DISEASE

Abstract

Most diseases involve many genes in complex interactions, in addition to physical and cultural environmental factors. If a disease is caused by genetic and environmental factors, its etiological origin can be referred to as having a multifactorial pattern. The common multifactorial diseases encompass environmental inuences on the causal processes. Thyroid is a multifactorial type of origin of disease. The epidemiological studies show that if thyroid disease is caused by the interaction of both genetic and environmental factors, then mostly it is autoimmune thyroid disease. When the antibodies attack the thyroid gland, it is called Auto Immune Thyroid Disease (AITD). The present study attempts to examine whether the occurrence of thyroid disease in a micro area is due to autoimmune conditions. To prove the fact clinically, blood of thyroid patients were collected and tested in a laboratory. The result shows that most of the patients have autoimmune thyroid disease. Moreover, some environmental and genetic factors were also examined since thyroid disease is a multifactorial origin of disease.
