The latest research shows a large percentage of MG patients suffer from AChR antibody induced autonomic system disorders. The autonomic system regulates the function of those muscles and processes that are automatic and not under your control. Gastro-intestinal issues, bowel and bladder problems and many other symptoms are commonly reported. Both constipation and diarrhea are common results. Like the MG attack on voluntary muscles, MG associated autonomic disorder is not curable. Immunosuppressants may help. Otherwise, your doctor can prescribe drugs to help control the symptoms.
