your T4 Thyroxine meds is not the cure for weight loss.
It takes some time to build up the proper dosage of any medication. I am on 175 MCG of Synthroid (I built up to this level over the course of a year), it took almost 9 months for me to feel normal on the medication and within the last 3 months I started to loose weight as had been initially hoped by my doctor. Best wishes. Steve
This is the patient forum. Dr Lupo is on the expert forum.
25mg daily is a good start, but you should be retested in 6 weeks. It is very important to at least have a free t4 done with your TSH, and preferably best if you also have a free t3 done as well. Thyroxine is not a salt tablet, it is a thyroid hormone. At this point in your treatment, I would try to not focus on weight loss.....just getting your levels optimal. Eventually the weight will come off if you eat responsibly and exercise accordingly, and take your thyroid meds as prescribed by your Dr.
Hope this is helpful. :)
