If you live with autoimmune thyroid disease (AITD), you might have also experienced symptoms of depression. You're not alone—and now, science is uncovering why these two conditions often go hand in hand.
A new study looked at the genetic link between AITD and major depressive disorder (MDD), and the results are eye-opening.
What Did the Study Find?
Researchers used large-scale genetic data to explore whether thyroid disease and depression are connected at the DNA level. Here's what they discovered:
There is a genetic link between thyroid disease and depression. People with certain genes may be more likely to develop both conditions.
Some genetic markers are shared between the two diseases. These markers weren’t linked to thyroid disease or depression on their own—but they were when both conditions were present together.
Depression may increase the risk of thyroid disease. The study found evidence suggesting that depression could play a causal role in triggering autoimmune thyroid disease.
Key Takeaways for Patients
Mental health matters. If you have thyroid disease and struggle with depression, it's not just in your head—your genes may be playing a role.
Treating depression may help your thyroid. While more research is needed, managing your mental health could support your overall well-being, including your thyroid.
Talk to your doctor. If you're experiencing symptoms of depression—like low mood, fatigue, or trouble concentrating—bring it up during your thyroid check-ups.
Final Thoughts
This research is a reminder that our bodies and minds are deeply connected. If you’re living with thyroid disease, paying attention to your emotional health is just as important as managing your hormone levels. And if you’re feeling overwhelmed, know that help is available—and you deserve it.
