Will I continue to lose weight with my thyroid condition?

About a year ago I started gaining weight rapidly despite a healthy diet and exercise. I also had extreme fatigue, constipation, stiff joints, muscle weakness, brittle fingernails and hair. A few months ago I was diagnosed with hypothyroidism. My doctor prescribed Synthroid and within 6 weeks, I’d dropped 15 lbs.

Does this mean I will continue to lose weight? He says my thyroid levels are normal, does that mean my metabolism is working correctly? I’ve tried to find information on this, but I just can’t find exactly what I’m looking for. I still need to lose about 50 lbs, but I’m still having issues with fatigue and it makes it extremely difficult to exercise.


  • I was diagnosed with hypothyroidism 15 years ago and experienced the same thing as you when I started Synthroid. I didn’t continue to lose weight once my thyroid hormone level was stabilized. I am pleased to add that over the years my body has responded as a normal body would to my eating habits. A book that I found helpful in the beginning and return to occasionally is "Living Well With Hypothyroidism" by Mary J Shomon

    No, my weight evened out and stayed there about 1.5-2 months after being steady on the Synthroid. If it doesn’t then something else is probably wrong. Same with the fatigue.
