Can lowering thyroid medication affect myasthenia gravis symptoms, and is it connected to low blood pressure, dry skin, hair, and nails?

Yes, there is a real connection worth paying attention to here. Thyroid disease is a known comorbidity of myasthenia gravis, meaning the two conditions are linked. Both stem from immune system dysfunction, so when one is not well-managed, it can influence how you feel overall — including your MG symptoms. The symptoms you're describing — dry skin, dry hair, brittle nails, and low blood pressure — can all be signs that your thyroid hormone levels are too low. These are classic signs that your thyroid isn't being adequately supported.

A blood pressure of 90/58 is notably low and should be discussed with your doctor promptly, especially alongside your other symptoms. Here's what's worth bringing up with your healthcare provider:

- Whether your current thyroid medication dose is still appropriate
- Whether your thyroid hormone levels need to be retested
- How your thyroid levels may be interacting with your MG management
- Whether a referral to an endocrinologist (a hormone specialist) might be helpful

Getting these levels balanced is important — not just for your thyroid, but for your overall wellbeing with MG. Don't wait too long on this one, especially with that blood pressure reading.
