These muscles usually include: Eyelids and muscles around the eyes \u2013 If MG only affects these muscles, doctors call it \u201cocular MG\u201d. About half of all MG patients fall into this category. Jaw and pharyngeal muscles. Arm and neck muscles. Muscles for breathing. The cause of MG is due to problems in the body\u2019s immune system. The immune system usually produces a protein called \u201cantibody\u201d that helps to prevent and fight against infections. However, the immune system of MG patients produces antibodies that mistakenly attack the junction between nerves and muscles, affecting normal muscle function."}
