Iodine Therapy in Chennai
What is this study?
Iodine therapy, also known as radioactive iodine therapy or I-131 therapy, is a treatment procedure used in nuclear medicine to manage various thyroid conditions, including thyroid cancer and hyperthyroidism. It involves administering a radioactive form of iodine, known as iodine-131 (I-131), which selectively targets and destroys thyroid cells, including cancerous or overactive thyroid cells.
What is the need for the study?
The primary purpose of iodine therapy is to:
- Treat thyroid cancer by destroying any remaining thyroid tissue, including cancerous cells, following surgery or other treatments.
- Manage hyperthyroidism by reducing the production of thyroid hormones and restoring normal thyroid function.
Iodine therapy is often recommended when other treatment options, such as surgery or medication, are ineffective or not feasible.
How do I prepare?
Preparation for iodine therapy may include:
- Thyroid Hormone Withdrawal: For thyroid cancer treatment, patients may need to temporarily discontinue thyroid hormone medication to allow thyroid-stimulating hormone (TSH) levels to rise, which enhances the uptake of radioactive iodine by thyroid cells.
- Low-Iodine Diet: Following a low-iodine diet for a specific period before therapy can reduce iodine intake and enhance the effectiveness of treatment.
- Baseline Tests: Your healthcare provider may conduct baseline tests, such as thyroid function tests and imaging studies, to assess your condition before therapy.
Your healthcare provider will provide detailed instructions on how to prepare for iodine therapy based on your specific medical history and treatment plan.
How is this scan performed?
The iodine therapy procedure typically involves the following steps:
- Administration of Radioactive Iodine: You will be given a dose of radioactive iodine (I-131) orally, usually in the form of a capsule or liquid. The radioactive iodine is absorbed by the thyroid gland, where it emits radiation, targeting and destroying thyroid cells.
- Radiation Safety Measures: Due to the radioactive nature of iodine therapy, strict radiation safety measures are implemented to protect both you and others from radiation exposure. This may include isolation precautions and specific hygiene practices.
- Monitoring: After receiving iodine therapy, you will be closely monitored by healthcare professionals to assess the treatment’s effectiveness and manage any potential side effects.
What should I do after the scan?
After iodine therapy, follow any post-procedure instructions provided by your healthcare provider, which may include:
- Isolation: You may need to stay in isolation for a specific period to minimize radiation exposure to others.
- Hydration: Drink plenty of fluids to help flush out the radioactive iodine from your system.
- Follow-Up Appointments: Attend all scheduled follow-up appointments for monitoring and assessment of your response to treatment.
Are there any risks in the study?
While iodine therapy is generally safe and well-tolerated, there are some risks and potential side effects to consider, including:
- Thyroiditis: Temporary inflammation of the thyroid gland, which may cause neck tenderness, swelling, and discomfort.
- Hypothyroidism: In some cases, iodine therapy may lead to an underactive thyroid gland (hypothyroidism), requiring thyroid hormone replacement therapy.
- Radiation Effects: Rarely, iodine therapy may result in radiation-related complications, such as damage to salivary glands, changes in taste, or dry mouth.
Your healthcare provider will discuss the potential risks and benefits of iodine therapy with you and address any concerns you may have before proceeding with treatment.
It’s essential to follow all instructions provided by your healthcare provider and communicate any symptoms or concerns you experience during or after iodine therapy. Your healthcare team is here to support you throughout your treatment journey and ensure the best possible outcomes for your health.
