Welcome to the forum, Suzzanne,

It could be that you are overmedicated ie your metabolism has increased too much. If you post your thyroid results with the lab ref ranges it will help members to advise.

Some people do have unwanted weight loss on Levothyroxine. myself included, and need to eat more to maintain weight. There's something perverse about hypothyroidism, if you've always been underweight it can be hard to maintain your weight but if you had to diet to control weight it will increase despite calorie restrictions and increased exercise.

Lola, that is my theory, it isn't necessarily correct

I have to disagree here. I was thin my whole life, never looked at a scale and ate what i wanted. In 2010 after feeling ill for 2 months with no appetite, i suddenly gained 11lbs in one week and a total of 30lbs in three months, all Myxedema and fluid and have never loss much while on treatment. I have Hashimoto's and have treatment resistance, which i think is due to inflammation. I'm now doing t3 only and praying it helps. I'm so terribly swollen and tired.

Faith, when you're optimally medicated the mucin and fluid should start to improve. I hope it won't be much longer.

Thank you for being so kind.

Have u been tested recently i would to make sure the dose is correct. I was on that dose some years ago it didn't help me lose weight has ur diet changed or r u getting more exercise or I have u recently been diagnosed with thyroid deficiency. If not i would visit gp as may be something else going on
