Other than levothyroxine, what are other alternatives for hyperthyroidism? It has been 3 years i still have no energy, and insomnia!

Some thots: You could consider that thyroid is still not fully regulated, but would doubt that is cause at this point. Anemia might be a consideration, but you could also, suffer a sleep disorder such as sleep apnea. You do emphasize fatigue and this does need to be evaluated fully, as several causes. Discuss with your doctor and plan the next step. ...Read more

I am hypothyroid and on 150mcg/day levothyroxine. Tsh was .53 two weeks ago. I am still cold, have low bp, high heart rate, depressed, and insomnia.

I am hypothyroid and on 150mcg/day levothyroxine. Tsh was .53 two weeks ago. I am still cold, have low bp, high heart rate, depressed, and insomnia.

Need more lab tests: Tsh does not tell the whole story. Have your doctor check free T4 and free t3 (liothyronine). Those are your actual thyroid hormone levels and might more accurately reveal whether you are on enough medication or even the right medication. Levothyroxine is T4 and needs to be converted to t3 (liothyronine), so a low free T3 (liothyronine) means that you are not converting. Low T3 (liothyronine) can cause many of the symptoms you describe. ...Read more

Thyroid labs: Hi. You need to have your TSH and free T4 checked. Your symptoms could be related to thyroid hormone over-replacement. Of course, it may be completely unrelated (which is probably more likely), but you won't know without testing your thyroid function. Good luck! ...Read more

Maybe hyperthyroid: Hyperthyroidism (too much circulating thyroid hormone) will often produce rapid heart rate and insomnia - along with other symptoms like diarrhea, weight loss, and jitteriness. Low thyroid may cause weight gain, sluggishness, coarse/dry skin, and constipation. Ask your care provider about your symptoms. Please do not "freelance" with Cytomel or synthroid, (thyroxine) as this may harm you! lgromko md. ...Read more

Not for hyper: Adding thyroid hormone replacement to a hyperthyroid gland will exacerbate the problem. If there is underlying adrenal insufficiency, adrenal crisis is more likely to occur in someone with hyperthyroidism. Highly recommend endocrine evaluation if you have these issues. ...Read more
