Treatment of hypothyroidism involves thyroid hormone replacement and the dose depends on the severity of the underproduction.  Your doctor will look at your blood tests and your symptoms to adjust your thyroid replacement treatment dosage.  You are encouraged to have a thyroid blood test done regularly.   Initially, you will need to do the blood test more frequently to monitor the response from your treatment.  Once your condition has stabilised, you will only need to repeat the blood test every 6-12 months.  Always consult and follow your doctor’s instructions.
