Obese. supposed to take metformin for pcos & synthroid (thyroxine) for hypothyroid. had severe diarrhea, so stopped taking. now can't lose any significant weight?

See your doctor: Metformin can cause diarrhea, and some people cannot take it, but most can if they work their way up slowly. Begin at just 500 mg/day, and then after a few days increase to 500 2x/day. The body usually gets used to it. All this requires careful management, and i recommend discussing this with your doctor. Are you on the right dose of synthroid (thyroxine)?
