Hyperthyroidism: causes, symptoms, and treatment methods
Understanding Thyrotoxicosis
Thyrotoxicosis is a condition caused by the excess release of thyroid hormones, such as thyroxine (T4) and triiodothyronine (T3). This hormonal imbalance often leads to an increased metabolic rate in the body, which can manifest through various clinical symptoms, including nervousness, increased heart rate, weight loss, tremors, and weakness.
The diagnosis of thyrotoxicosis includes tests for the levels of thyroid hormones in the blood, ultrasound examination of the thyroid gland, as well as other methods. Treatment aims to normalize thyroid function and reduce hormone levels. Depending on the cause and severity of the condition, treatment options may include medication therapy, radioactive iodine, and sometimes surgical intervention.
Etiology of Thyrotoxicosis
Thyrotoxicosis is a pathological condition caused by excessive secretion of thyroid hormones, such as thyroxine (T4) and triiodothyronine (T3). The manifestations of this syndrome may be related to various pathological processes in the thyroid gland, including goiter, toxic adenoma, as well as different forms of thyroiditis. Other causes of thyrotoxicosis may include the intake of excessive amounts of thyroid hormones in the form of medications, such as iodine-containing supplements or drugs used to treat hypothyroidism.
It is important to consider that the pathogenesis of thyrotoxicosis can be multifactorial and requires a comprehensive approach to diagnosis and treatment. Understanding the main causes of this condition allows for the effective selection of a strategy for medical or surgical treatment depending on the specific case.
- Chronic thyroiditis (Hashimoto): an autoimmune disease characterized by an enlargement of the thyroid gland and impaired function.
- Goiter: enlargement of the thyroid gland, often caused by iodine deficiency in the diet.
- De Quervain’s thyroiditis: acute inflammation of the thyroid gland, most commonly following a viral infection.
- Thyrotoxicosis of solid thyroid formations: hormonally active tumors, such as toxic adenoma or multiple nodules.
- Intake of excessive iodine: symptomatic thyrotoxicosis may occur with the intake of large doses of iodine-containing drugs.
Clinical picture of Thyrotoxicosis
The clinical picture of thyrotoxicosis is usually characterized by a variety of symptoms reflecting the excessive action of thyroid hormones on various systems of the body. Patients with thyrotoxicosis may experience significant exuberance, increased heart rate, tremors of the extremities, excessive sweating, irritability, anxiety, insomnia, exhaustion, as well as changes in appearance, such as tachycardia and exophthalmos. Some patients may also experience increased sensitivity to heat, diarrhea, muscle weakness, hair and nails may become brittle and fragile, and there may be an enlargement of the thyroid gland.
As uniquely diverse symptoms of thyrotoxicosis are, their similarity to other pathologies creates the necessity for a comprehensive differential diagnosis and detailed medical examination to correctly identify and effectively manage this condition.
- Tachycardia: an increase in heart rate is one of the characteristic signs of thyrotoxicosis, which can lead to cardiac arrhythmia.
- Exophthalmos: protrusion of the eyes (exophthalmos) is a typical sign of thyrotoxicosis, caused by swelling of the eye muscles and increased volume of fat tissue behind the eyeball.
- Tremor of the extremities: involuntary shaking of the hands or feet often accompanies thyrotoxicosis, especially when performing movements.
- Increased sweating: excessive perspiration can be a noticeable symptom of thyrotoxicosis due to increased metabolism and elevated heat dissipation.
- Anxiety and insomnia: psycho-emotional disorders, including anxiety, irritability, and insomnia, may be observed in patients with thyrotoxicosis due to the impact of thyroid hormones on the central nervous system.
Expert opinion on the treatment of Thyrotoxicosis
Expert opinion on the treatment of hyperthyroidism emphasizes the importance of an individual approach to each patient, taking into account the causes of the disease’s development and its clinical manifestations. The effectiveness of therapy depends on the accurate diagnosis of the type of hyperthyroidism, as well as any accompanying conditions and the overall health of the patient. Experts recommend a comprehensive treatment plan that includes medical correction, radioactive therapy, or surgical intervention depending on the specific case.
One important aspect of treating hyperthyroidism is the monitoring of thyroid function after the completion of active therapy to avoid relapses and complications. Experts also note the necessity for regular monitoring of the patient’s condition, adjusting the therapy as needed, and maintaining optimal thyroid gland function to achieve stable remission of the disease.
Methods for diagnosing Thyrotoxicosis
The diagnosis of thyrotoxicosis is based on a comprehensive analysis of clinical symptoms, laboratory data, and instrumental studies. This includes analyzing the levels of thyroid hormones in the blood – free thyroxine (FT4), free triiodothyronine (FT3), and thyroid-stimulating hormone (TSH). Additional diagnostic methods are ultrasound examination of the thyroid gland to assess its size and structure, thyroid scintigraphy to identify functional pathologies, as well as biopsy of thyroid tissue to rule out malignant processes.
It is important to note that the correct diagnosis of thyrotoxicosis requires a comprehensive approach and strict adherence by the attending physician to all necessary laboratory and instrumental studies. Only an extensive and thorough examination of the patient will accurately determine the cause and form of thyrotoxicosis, which is key to effective treatment of this condition.
- Clinical symptoms and history: The doctor conducts a thorough examination of the patient, identifying characteristic signs of thyrotoxicosis, such as tachycardia, tremor, exhilaration, exophthalmos, etc.
- Laboratory tests: Examination of the levels of thyroid hormones (FT4, FT3) and thyroid-stimulating hormone (TSH) in the blood to assess thyroid function.
- Ultrasound examination of the thyroid gland: Allows for evaluation of the size, structure, and pathologies of the thyroid gland.
- Thyroid scintigraphy: Is important for assessing the functional activity of the thyroid gland and detecting anomalies in the functioning of this organ.
- Thyroid biopsy: Conducted for differential diagnosis and exclusion of malignant tumors.
Methods for treating thyrotoxicosis
The treatment of thyrotoxicosis depends on its cause and the severity of clinical manifestations. The main treatment methods include pharmacological correction, radiotherapy, surgical intervention, and radioiodine therapy. Pharmacological treatment may include the use of antithyroid drugs, beta-blockers to control heart rate and symptoms of hyperthyroidism, as well as medications to suppress the synthesis of thyroid hormones.
Surgical treatment is applied in the presence of certain thyroid pathologies, such as nodular goiter with a high risk of malignancy or toxic adenoma. In cases unsuitable for surgical intervention or ineffective medical treatment, radioiodine therapy may be used. A successful strategy for treating thyrotoxicosis requires an individualized approach considering the patient’s characteristics and the underlying causes.
-
– Antithyroid medications: such as thiamazole and propylthiouracil are used to suppress the synthesis of thyroid hormones and control hyperthyroidism.
– Beta-blockers: are used to reduce heart rate, control tremors, and other symptoms associated with excess triiodothyronine.
– Surgical intervention: excision of part or all of the thyroid gland may be necessary in cases of hyperfunction caused by goiter or toxic adenoma.
– Radioactive iodine therapy: a treatment method in which the patient is given radioactive iodine to destroy hyperfunctioning thyroid cells.
– Symptomatic treatment: includes the prescription of medications to improve the patient’s overall condition, reduce anxiety and depression, as well as restore the body’s nutritional status.
