To my understanding, Lyme disease often messes with the endocrine [hormonal] system, including thyroid activity. When I had Lyme, my doc put me on thyroid supplements for a brief while till the Lyme was gone, and my own system recovered. Since then, almost ten years later, I remain fine.
To my understanding, Lyme often affects the endocrine (hormone) system, which includes thyroid function, so yes, thyroid function could be suppressed by Lyme. Have you spoken with your Lyme doc about it? If there is low thyroid function, it can be easily balanced with thyroid meds until the Lyme is gone.
Thanks Jackie, I've got an appointment next week so will speak to him about the link
