4. Genetic Predisposition
The medical trend that seems to appear with Hashimoto’s Thyroiditis and other autoimmune disease is that they tend to hereditary. Often, a family member who is afflicted with this type of disease can trace it back to through their family tree.
The most severe being goiter. As the symptoms can easily be disguised or overlooked as daily ailments, it can go unnoticed for a long time. Most often people go to the doctors, feeling fatigued and assume that it is due to their heavy work schedule.
It is only through testing that the real problem, such as Hashimoto’s Thyroiditis can be found. Studies of Wick and Hu of ’93 and of Bottaccioli of ’95 on “obese strain of chicken”, a breed of chickens that spontaneously develop autoimmune thyroiditis, have shown both the genetic basis, demonstrating two gene families responsible for the abnormal autoreactivity of the immune system and the inherent predisposition of the thyroid gland in response to stress.
