Hashimoto's disease
"If you are taking Synthroid and you are still depressed, overweight or losing hair (all symptoms of hypothyroidism, which this drug treats) then your dose is still not high enough. If your doctor tells you that you are &quot;within the normal range, &quot;switch doctors - if you are still having symptoms then your dose should be higher. I have been on this medication for several years now and as long as I&#039;m on the right dose, I feel fine. I know I need an adjustment when I start to get tired and depressed. Those are the two most obvious symptoms for me (as well as hair loss). I have used low-carb diets effectively (New Atkins for a New You is good - has a section for vegetarians) to lose the weight I had gained when my thyroid became inactive."
