Myasthenia gravis causes muscle weakness and fatigue in rare autoimmune disorder

Myasthenia gravis (MG) is a rare autoimmune disorder that causes muscle weakness and fatigue. It affects communication between nerves and muscles, particularly impacting eye movement, facial expressions, and breathing. Improved awareness and diagnostic techniques have led to more frequent diagnoses. The exact cause of MG is not fully understood, but it involves the immune system attacking the body. Factors like genetics, infections, and certain medications may contribute. The thymus gland may also play a role in the disorder. Diagnosis involves physical exams, blood tests, and imaging scans. While there is no cure, treatments include medications, intravenous therapies, and sometimes surgery to remove the thymus gland. Many patients can manage symptoms and maintain active lives with appropriate care.
