Introduction
Side effects of I-131 therapy may include thyroid enlargement, thyroid discomfort, dry mouth, risk of radiation exposure, and hypothyroidism. After radiation-induced damage to thyroid tissue, inflammation or autoimmune reactions may occur. Thyroid enlargement may present as neck swelling, shortness of breath, and difficulty swallowing. It is recommended to seek medical attention promptly.
Possible side effects of I-131 therapy include thyroid enlargement, thyroid discomfort, dry mouth, radiation exposure risk, and hypothyroidism. The specific analysis is as follows:
1. Thyroid enlargement: After radiation-induced damage to thyroid tissue, inflammation or autoimmune reactions may occur. Thyroid enlargement can manifest as neck swelling, shortness of breath, and difficulty swallowing.
2. Thyroid discomfort: During the destruction of thyroid tissue, the release of thyroid hormones and other substances triggered by iodine-131 may cause patients to experience thyroid pain, swelling, or sore throat shortly after treatment.
3. Dry mouth: Damage to the salivary glands may lead to glandular swelling and inflammation, resulting in symptoms such as dry mouth and difficulty swallowing.
4. Radiation exposure risk: Iodine-131 is a radioactive isotope. During treatment, the patient temporarily becomes a source of radiation, potentially posing a certain radiation risk to people nearby.
5. Hypothyroidism: Following I-131 therapy, destruction of thyroid tissue may lead to decreased thyroid hormone levels, resulting in hypothyroidism.
It is recommended to seek timely medical attention and receive standardized treatment under a physician's guidance to avoid delays in managing the condition.
