My wife had her thyroid out three weeks ago due to cancer.
Although the surgery was curative, its been recommended for her to take a dose of radioactive iodine (I131) to prevent a possible recurrence in the future.
She needed to wait to become very hypothyroid prior to being given the dose.
A TSH is a test that helps to measure thyroid function.
A normal level is up to about 4.5.
The higher the TSH, the greater the level of hypothyroidism.
Her TSH was 64 this past Monday.
It helps to explain her fatigue, feeling like she was walking through a cloud and the difficulty in putting a complete sentence together.
She takes the I131 tomorrow and can then start on thyroid medications.
The clouds should lift quickly.
