Houston, I would get a second opinion, there are a lot of different treatments for MG, Soloris, Ultimoris, Rituxan, IVIG just to name a few

Myasthenia gravis (MG) is linked to type 2 diabetes (T2DM), with studies showing a higher risk of diabetes in people with MG, potentially due to corticosteroid treatment, reduced physical activity, and underlying inflammatory or metabolic dysregulation. T2DM may also be a risk factor for developing MG, and some research suggests that diabetic MG could be a distinct clinical subtype. The association is complex, with factors like age, sex, and even the specific MG subtype potentially influencing the risk and manifestations of both conditions. Corticosteroid Treatment: A common treatment for MG is corticosteroids, which are known to increase blood sugar levels and can cause high blood sugar or even type 2 diabetes.
Reduced Physical Activity: MG can cause muscle weakness and fatigue, leading to reduced physical activity levels. This sedentary lifestyle can contribute to insulin resistance and an increased risk of T2DM.
Underlying Inflammation: MG is an autoimmune disease, and diabetes, particularly T2DM, is associated with chronic inflammation. These overlapping inflammatory pathways may contribute to the increased prevalence of diabetes in MG patients.
Metabolic Imbalance: Inactivity and other factors in MG can disrupt glucose and lipid metabolism, potentially leading to insulin resistance even in MG patients not on corticosteroids.

How Type 2 Diabetes Can Relate to Myasthenia Gravis
Increased Risk Factor: Research indicates that T2DM can be a significant risk factor for developing MG, particularly in women over 50.
Distinct Subtype: Some studies suggest that MG in patients with diabetes might be a unique or distinct subtype, differing from typical MG classifications.
Immune System Dysregulation: Diabetes can aggravate the immune response, which is central to the autoimmune attack in MG, potentially increasing the risk of developing the condition.
Management Considerations
Physical Activity: For MG patients, engaging in individualized physical activity programs can help manage blood sugar levels and reduce the risk of T2DM.
Corticosteroid Management: Because corticosteroids can induce diabetes, managing their use is crucial to control blood sugar levels.
Monitoring: Regular monitoring of blood sugar and other metabolic indicators is important for people with MG, even those not taking corticosteroid

I have been on Prednisone 10mg for about 8 years and am concerned about developing diabetes but my Neurologist doesn’t feel other treatments would work as well for me. I also see eye doctor every 4 months to control eye pressure as side effect of Prednisone . I am prescribed Brimododin drops
