Im sorry. I must have mistyped. i'm not experiencing a weight gain but a severe weight loss. I've lost 100lbs so far. I lost 12 just last week. The dr won't even entertain retesting. I had to quit taking the synthroid because it was making me lose faster. I know I'm dehydrated because my lips and mouth are very dry and you can pinch the skin on top of my hand and it stays. For some reason I've cut my fluid intake in half. This naseau thing started 3 weeks ago and I can't seem to tolerate it. I even told the dr my sister has grave's disease. She dismissed me with a your levels are low the end. I don't understand how I can be hypo when im wasting away to nothing.
Hi, I am no expert whatsoever, but you could ask the Dr. to run another blood test to confirm the first one's results if you need reassurance. Craving the salty stuff can be a sign that you are not taking in enough water/fluids. The weight gain you have experienced is likely to be a combo of that med and your hypo, so by getting your thyroid corrected, you will be very fortunate to get to your ideal weight and be much better able to maintain that with continued thyroid med. I have been hypo for years, but still struggle with easily putting on weight. Good luck.
