What causes body twitching in myasthenia gravis?

Muscle twitching (called fasciculations) can happen with MG for a few different reasons. These are small, involuntary muscle movements that can occur in any muscle in your body.

Here are the main causes:

- Too much acetylcholine – If you're on MG medications like acetylcholinesterase (AChE) inhibitors, too much of this chemical can overstimulate your nerve receptors, causing muscle twitches
- MG itself – The condition can directly cause fasciculations, particularly in people with MuSK antibody-positive MG
- Cholinergic crisis – An overload of acetylcholine in the body can trigger twitching in muscles you control, like arms and legs It's always a good idea to let your MG specialist know if you're noticing new or worsening twitching. While it can be a manageable symptom, it's important to rule out anything more serious, especially if it's accompanied by breathing difficulties or other new symptoms.
