I was diagnosed with hypothyroid about 10 yrs ago and even after starting synthroid I struggled with with severe weight gain. To make a long story short.... I finally found an enternist who would actually take the time to listen to me. She explained to me that thyroid medication is one of those medications where there can be a huge difference between name brand and generic. After 9 yrs of taking levothyroxine, she put me on synthroid (take exactly as instructed) and my levels have been in normal range every since. It's a little more pricy for name brand, but definitely worth it!
I'm 3.5 weeks post op and have lost 15 pounds. Im 35 yrs old and I haven't felt this good since I was in high school.
