Autoimmune thyroiditis, most commonly known as Hashimoto's thyroiditis, is a chronic inflammatory disease of the thyroid gland. In this condition, the body's protective system—the immune system—mistakenly perceives the hormone-producing cells of its own thyroid gland as "foreign" and attacks them. This continuous attack by the immune system leads to the gradual destruction of thyroid tissue over the years. As a result, the gland's ability to produce hormones is limited, and over time, thyroid underactivity—hypothyroidism—develops. Hashimoto's thyroiditis is considered one of the most common causes of hypothyroidism.
Causes
The main factors for the onset of the disease are diverse and often interconnected:
1.
Family predisposition
– if there are cases of thyroid or other autoimmune diseases in the family, the risk increases significantly.
2.
Iodine-rich diet
– especially in cases where a genetic predisposition exists.
3.
Certain viral and bacterial infections
– which can activate the autoimmune process.
Initial Symptoms
In the early stages of the disease, symptoms resembling increased thyroid function are often observed, which can be temporarily misleading:
1. Increased sweating
2. Weight loss
3. Nervousness and irritability
4. Palpitations
This phase can be transient and gradually change into thyroid underactivity.
Symptoms of Hypothyroidism
As the disease develops, signs characteristic of hypothyroidism manifest, which can significantly affect the quality of life:
1. Fatigue, general weakness
2. Dry skin
3. Hair loss
4. Weight gain
5. Constipation
6. Difficulty concentrating
7. Memory impairment
8. Edema (swelling) in the upper and lower extremities
Diagnosis
A combination of several research methods is used for accurate diagnosis:
1. Palpation of the thyroid gland
2. Checking thyroid hormones and specific antibodies in the blood
3. Ultrasound examination of the thyroid gland
4. Scintigraphy (if necessary)
Treatment
The main approach to treating Hashimoto's thyroiditis is hormone replacement therapy:
1. Thyroid hormone replacement medications are prescribed.
2. It is necessary to periodically monitor thyroid hormone levels to determine and adjust the correct dosage of the pill.
Thyroid function usually deteriorates gradually over the course of life; therefore, the dosage of the hormonal medication may change over time. Treatment, as a rule, continues throughout life because the damaged tissue of the thyroid gland does not recover, and the underactivity remains permanent.
