Myasthenia gravis (MG) affects skeletal muscles β the ones you consciously control. The rectum and anus involve smooth muscle (which MG does not directly target), but the external anal sphincter is a skeletal muscle, meaning MG could potentially affect it.

Myasthenia gravis (MG) affects skeletal muscles β the ones you consciously control. The rectum and anus involve smooth muscle (which MG does not directly target), but the external anal sphincter is a skeletal muscle, meaning MG could potentially affect it.
That said, direct research on MG's impact on the rectum and anus is very limited. What is more commonly discussed is that MG can affect muscles involved in swallowing and the digestive process more broadly.
If you're experiencing issues in that area, it's worth raising with your neurologist or gastroenterologist, as it could be related to:
- MG muscle weakness affecting nearby skeletal muscles
- Side effects from MG medications
- A comorbidity worth investigating
Don't hesitate to bring this up with your care team β no symptom is too awkward to mention, and they've truly heard it all!
