Had my RNY surgery March 9th and have lost 49 lbs but only lost two all last month. I was in hospital 3 days start of July with liver enzyme issues and my TSH (thyroid) numbers had went from hypo to hyperthyroid. Dr took me off synthroid for 3 days and then went back on 1/2 dose (50 mcg). Did that for a week and a half and the mental fog and sluggishness came back. Dr took me off synthroid completely. I go back Aug 20th to have TSH checked again. Could my going on and off and on and off synthroid be causing this drastic slow down in weight loss? I am still 30 lbs from my goal of 160 and was losing 2 lbs a week before this all happened. I have really enjoyed reading everyone's posts and getting some great advice on here!

that could very well be - but in addition, when you get fairly close to goal, your weight loss does slow down a lot. The last 20 lbs were a BEAR for me to lose...

Yeah I was just hoping to get to the low 180's before the slow down hit. ??. Am trying to stay positive and hope it kicks back in a bit faster.
