What Is Myasthenia Gravis? Myasthenia gravis is a chronic condition that causes muscles to tire and weaken easily. For example, if you have myasthenia gravis, you may notice that during a meal, your jaw muscles become tired and weak, interfering with your ability to chew food.
In people with myasthenia gravis, the body produces antibodies that block the muscle cells from receiving messages (neurotransmitters) from the nerve cells. The exact cause of myasthenia gravis is unknown. In some cases, it is linked to tumors of the thymus (an organ of the immune system).
