What Do My Thyroid Function Test Results Indicate?
Question: Need advice on hypothyroidism.
This is for my wife, aged 37 yrs, height 5ft 3inch, weight 63 kg, who has been on Thyronorm for about 8 years. Last couple of readings and dosage are as below:
24-12-2014: TSH = 0.08, FT4 = 1.15, FT3 = 3.2, she continued thyronorm 100 mcg daily dose
15-04-2015 : TSH 0.45 , continued with Thyronorm 100 mcg
9-Feb-2016: TSH =1.58 , FT4=1.29, FT3 = 2.18
Other complaints - feel tired
All tests done from same lab(Thyrocare)
What will be the treatment plan ?
Is there a change in dosage suggested ?
Also, any risk factors ?
What can we do to reduce dependency on medicine dosage?
Thanks, XXXXXXX

Brief Answer:
Need to continue same dose
Detailed Answer:
Hi,
Welcome to HCM. I have gone through your questions and understand your concerns.
1. Your wife's current thyroid function is normal. So she need to continue with same medications
2. If taken in correct dose this medication is not associated with any side effects.
3. Regarding dependency
The treatment of hypothyroidism is thyroid hormone replacement (Thyronorm). That means her thyroid is not producing enough thyroid hormones and so we are replacing it.
To see if she can be taken off this medicine we should know if thyroid gland damage is permanent or not. You can do additional tests like ultrasound neck ( to see if thyroid gland is damaged) and anti thyroid antibodies. If she is having high anti thyroid antibodies or her thyroid gland is showing damage in ultrasound, she is probably having permanent hypothyroidism and needs to be on life long medications.
If antibodies are negative and ultrasound is normal, you can decrease the dose progressively as 75,50,25 and stop it provided the repeat Tsh every 6 weeks after reducing the dose is normal.
Hope I have answered your questions. If you have any further questions, I will be pleased to help you.
