Thanks for query to this forum.

You seem to be having Hypothyroidism and taking Thyronorm 75mcg/day. TSH is .99 and T4 is 10.4 are in normal range.

In Thyroid disorder dose change depends on result of thyroid function and clinical finding like Heart rate and symptoms. If dose is high for the patient then T4 level is more and symptoms of hyperthyroidism like fast heart rate, increased hunger (Appetite), perspiration, anxiety and weight loss can occur. You did not mention that you have such symptoms.
Before all these symptom appear we can detect rising level of T4 (Thyroxine).

Therefore you seen to be taking right medication - that is good; but you must check with your Physician at least twice in a Year.

Hope this information is helps you and if you have anything to ask, I will be available to answer that.

Thanks for your follow up.

If 10.4 reported as Hyperthyroid for that lab, then you may be required to reduce dose of Thyronorm.
We may repeat FT3, FT4 and TSH to be sure before reducing dose.

Please scan and attach the report of Thyroid function, So that I can understand better. You have a feature to upload the reports by yourself on the right side of this query page. Please utilize it.

Thanks for your prompt response.

Your T4 is 10.4 micro gm/dl; normal range is 4.5 to 12.5 micro gm/dl. Hence your T4 is within normal range.

Yes, you are under weight as your BMI is 17.4 it should be >19 minimum.

Please take good diet with high calories 2000 K cal balance of protein, Fats and Carbohydrates along with exercise aerobic and weight training.
You may also be given Vitamin and mineral supplements.

Hope this information is useful and helps to gain weight.

Please consult Physician and get proper prescription, and please keep me informed about progress.
