Total thyroidectomy 1/15 I lost 18 lbs. Can you have hyperthyroid symptoms if too much Levrothroxine? Want to loose 10 more. Advice or symptoms?

Yes. If the thyroid dose is too high, you can be hyperthyroid even though you have had a thyroidectomy. It's not a good idea to lose weight thru thyroid med. It hurts your heart, bone, muscles...
