AI Overview.....
Yes, myasthenia gravis (MG) can be associated with lower levels of iron, though the relationship is complex. Studies have found that patients with MG, particularly non-anemic and premenopausal female patients, may have lower serum iron and transferrin saturation levels compared to healthy individuals. This can be due to several factors, including dietary issues from swallowing difficulties, chronic infections, inflammation, and the use of immunosuppressive treatments.
Reasons for lower iron levels in MG
Dietary intake: Difficulty swallowing (dysphagia) or chewing can lead to reduced food and iron intake.
Chronic inflammation: Autoimmune diseases like MG involve chronic inflammation, which can lead to reduced iron levels through mechanisms involving inflammatory cytokines like IL-6, say ResearchGate.
Medication side effects: Long-term immunosuppressive treatments, which are common in MG management, can contribute to anemia or iron deficiency.
Chronic infections: MG patients may be more susceptible to chronic infections, such as pneumonia or intra-abdominal abscesses, which can cause anemia.
Associated conditions: Some patients may have other conditions that contribute to iron deficiency, such as atrophic gastritis or other autoimmune diseases.
Important considerations
Not all MG patients will have low iron levels.
The link appears to be stronger in certain groups, such as premenopausal females.
The relationship between MG and iron levels is an active area of research, and the impact of immunotherapy on iron metabolism is still being studied, with some evidence suggesting that immunotherapy may not significantly improve iron levels in some patients, note Oxford University Research Archive.

I was diagnosed as anemic a couple years before my MG diagnosis. I believe I had MG a couple years before I finally got diagnosed.

I hope that helps!

Thanks for that,it was very helpful
