Key Takeaways
The proper functioning of the thyroid gland has a significant impact on the entire human body. The hormones produced by the thyroid gland spread throughout the body, with the level of their activity determining the overall health of the body. Disorders in the proper functioning of the thyroid gland can lead to malfunctions in the nervous system, circulatory system, digestive system, and respiratory system. The most common cause of thyroid disorders is iodine deficiency in the environment, but other factors should also be considered, such as autoimmune thyroiditis or Hashimoto's disease.

Hashimoto's disease what is it?
Hashimoto (named after the Japanese physician Hakaru Hahimoto, who first described the disease in 1912) is a chronic, lymphocytic inflammation of the thyroid, which is one of the many autoimmune diseases associated with immune system disorders. The immune system stops defending the body from infections and begins to produce inflammation in its own tissues. It treats thyroid protein as an enemy and destroys it.
Hashimoto's disease is the cause
Unfortunately, the causes of Hashimoto's disease are not entirely known. The disease primarily affects middle-aged women, but it is increasingly diagnosed in young people, and even children. Genetic predispositions are the leading cause of hashimoto disease. Particularly at risk are people with family history of thyroid disease or patients with type 1 diabetes. The autoimmune triggering factors for thyroiditis can be chronic stress, fatigue, mental problems. There is no evidence that infections (viruses) have influenced the development of this disease in any way.
Hashimoto's disease is a symptom
Hashimoto's can run without any significant symptoms, causing the sick to live unconsciously with the disease. The disease itself, contrary to popular belief, is non-existent. Sometimes the thyroid gland gradually enlarges, forming a will, or it can shrink. It initially releases the correct or even excessive amount of hormones. After many months or years, it turns into an inadequacy, which causes a deterioration in health and well-being.
Hashimoto's disease is a cure
Managing Hashimoto's thyroiditis requires a dual therapeutic approach: standard medical hormone replacement using levothyroxine to normalize circulating fT4 and TSH levels, coupled with comprehensive lifestyle and dietary interventions. The latter focuses on anti-inflammatory nutrition, targeted replenishment of key micronutrients (selenium, zinc, vitamin D3, iron), chronic stress reduction, and gut barrier optimization to achieve lasting symptomatic remission.
