MG stands for Myasthenia Gravis, a chronic autoimmune disorder that affects communication between nerves and muscles. It occurs when the immune system mistakenly attacks the receptors for acetylcholine, a neurotransmitter essential for muscle contraction. This leads to muscle weakness and fatigue, particularly in the eyes, face, and throat. Symptoms of MG can vary widely among individuals and may include drooping eyelids, double vision, and difficulty swallowing or speaking. While there is no cure, treatments such as medications and therapies can help manage symptoms and improve quality of life for those affected by the condition.
