Thanks for using Healthcaremagic,
I have gone through all the information provided by you, your thyroid function report was TSH 0.02 in september last year and now it is 10.72 it is high and suggestive of Hypothyroidism
or underactive Thyroid.
Your symptoms of hair fall
,malaise may be due thyroid condition but weight loss
is not usually seen with hypothyroid state.
Please wait for FT3 and FT4 report if they are low then in consultation with your Physician treatment with low dose of Thyroxine
will be required.
In case of Hypothyroidism supplementation is exactly same hormone which is produced by our body hence it safe to take this medication.
Hypothyroid state may cause menstrual irregularity and pregnancy difficult sometimes it's correction is highly desirable and in most case treatment is for long duration may be lifelong.
Hope this information helps.
