Myasthenia Gravis: Understanding the Silent Muscle Weakness
Myasthenia Gravis (MG) is a rare but serious autoimmune neuromuscular disorder that leads to weakness in the body’s voluntary muscles—the ones we consciously control. Though it may sound intimidating, with the right diagnosis and treatment, most people with MG can lead stable, fulfilling lives. What Is Myasthenia Gravis? Myasthenia Gravis occurs when the immune system produces antibodies that interfere with the communication between nerves and muscles. Normally, nerve endings release a neurotransmitter called acetylcholine , which binds to receptors on muscles to trigger contraction. In MG, these receptors are either blocked or destroyed, causing muscles to tire quickly and recover slowly. What Causes It? The exact cause is unknown, but MG is autoimmune in nature, meaning the body’s own defense system attacks healthy tissue. Some cases are linked to problems with the thymus gland , a part of the immune system that may produce abnormal antibodies. Common Symptoms of Myasthenia G...
