So what doesn't make sense is that if she's complaining that the thyroxine isn't enough. No, she's complaining that she was overdoing it and gaining weight because of it, right? No, it's usually the other way around. Oh, the other way around. If you're hypothyroid, you tend to gain weight a little bit.
