Hashimoto’s Disease: When Your Immune System Slows You Down

6. Treatment: Medication

Hashimoto’s disease is typically diagnosed with a blood test that checks levels of thyroid-stimulating hormone (TSH). When TSH is high, it usually means the thyroid isn’t making enough hormones. The standard treatment is a daily dose of synthetic thyroid hormone (levothyroxine), which replaces what the body isn’t producing. Most people respond well to this medication, but it often needs to be taken long term. Regular blood tests help doctors adjust the dose as needed. Some medications and supplements—like calcium, iron, estrogen, and certain acid reflux or cholesterol drugs—can interfere with absorption, so timing matters. With the right treatment plan, symptoms usually improve or go away.
