Best Hyperthyroidism Overactive Thyroid Doctors in Kolkata

Types of Hyperthyroidism

Hyperthyroidism can be classified into different types based on its underlying cause:

• Graves' disease: This autoimmune disorder is the most common cause where the body's immune system attacks the thyroid, causing it to overproduce hormones.

• Toxic adenoma: These are noncancerous lumps in the thyroid gland that secrete excess hormones.

• Toxic multinodular goitre: This condition is characterised by the presence of multiple overactive thyroid nodules in the thyroid, which collectively produce an excess of thyroid hormones.

• Thyroiditis: This refers to inflammation of the thyroid gland that can lead to a temporary state of hyperthyroidism due to the release of stored hormones into the bloodstream.

Symptoms of Hyperthyroidism

The symptoms associated with hyperthyroidism can differ among individuals but typically include:

• Weight loss despite an increased appetite

• Rapid or irregular heartbeat

• Nervousness, irritability, and trouble sleeping

• Tremors in the hands

• Excessive sweating

• Frequent bowel movements

• Enlarged thyroid gland (goitre)

• Fatigue and muscle weakness

Tests to Diagnose Hyperthyroidism

Doctors specialising in the treatment of thyroid overactivity or hyperfunctioning thyroid may recommend a series of tests to confirm a diagnosis of hyperthyroidism:

• Blood test: This test measures levels of thyroid hormones. Elevated T4 and T3 levels with suppressed TSH indicate hyperthyroidism.

• Ultrasound Scan: This imaging technique enables visualisation of the thyroid gland to detect abnormalities such as nodules, enlargement, or inflammation.

• Radioactive Iodine Uptake: In this test, a small oral dose of radioactive iodine measures the thyroid's iodine absorption. High uptake levels suggest hyperthyroidism.

• Thyroid Scan: Using a radioactive tracer, this scan provides detailed images of the thyroid gland's structure and function.

Treatment or Surgery Options for Hyperthyroidism at Apollo Hospitals, Kolkata

Apollo Hospitals houses some of the best doctors adept at treating excessive thyroid hormone and thyroid overactivity, offering several comprehensive treatment options:

• Antithyroid medications: Methimazole or propylthiouracil are commonly prescribed to inhibit the production of thyroid hormones by the thyroid gland.

• Radioactive iodine therapy: Involves consuming radioactive iodine orally, which selectively targets and destroys part of the thyroid gland, thus reducing hormone levels.

• Beta Blockers: These medications, such as propranolol or atenolol, are used to alleviate symptoms like rapid heart rate, palpitations, and tremors

• Surgery: In severe cases or when other treatments are ineffective, surgical removal of part (subtotal thyroidectomy) or all (total thyroidectomy) of the thyroid gland may be recommended.
