Hi Lovelabs. Lyme disease can affect thyroid and other hormone levels. I think a TSH of 3.86 is high. I believe the high end of the new range is 2.5. Although it may not be typical, some people who have hypothyroidism lose weight.
It is important to get the Free T3, Free T3 (besides the T3 and T4) and thyroid antibodies tested. Have you had these levels tested? Treatment should not depend solely on the TSH. Many doctors do not test these levels and treat only by the TSH result. If antibodies are present, it can indicate Hashimoto's Thyroiditis which is an auto-immune thyroid disorder. Some people who have Lyme have this.
Some thyroid meds such as Synthroid is a T4 only med and meds like are Armour are a T3 and T4 med. Some people do well on one type, some on another. If Synthroid does not seem to work, you may need a dose increase or you may do better on a T3/T4 med. A T3 only med such as Cytomel may also be added.
I know it is confusing, but I think it is important to learn as much as you can so you can get the best treatment. I recommend always getting copies of your test reuslts. Lyme and hypothyroidism have many similar symptoms. Getting optimal thyroid treatment will help.
i think everyone who has Lyme should have their thyroid, adrenal and hormone levels tested. Cortisol testing checks adrenal function. It is my understanding that saliva testing is more reliable than blood testing. If you want further information on saliva testing, let tme know.
