Hi everyone. I'm new to the forum. I didn't find a post that got at a question rolling around in the back of my mind. I will reveal the depths and breadth of my ignorance, so be gentle

What causes Myasthenia Gravis? I know it is an autoimmune disease. Do you get MG randomly? Does it just happen?

Is there something that can cause it? I know scarlet fever can cause heart issues. I know strep throat can cause heart issues later in life. Is there some exposure to some chemical early in life that sometimes triggers MG? Does untreated repeated Strep Throat compromise things and trigger MG? See where I'm going?

I'm trying to sort out whether it is truly random or whether there are statistically significant environmental causation factors.

If I had a ten year old child ask me - how did you get this? What do I tell them? If my adult child asks me - how did you get this? What do I tell them?

I really appreciate your compassionate and detailed response. Seriously.

Thanks!
Eric
