![]() Taking anticholinesterase medicines 30 to 45 minutes before meals to reduce the risk of aspiration (food entering the lung passages) Precautions, which may help to prevent or minimize the occurrence of myasthenia crisis include: In severe crisis, a person may have to be placed on a ventilator to help with breathing until muscle strength returns with treatment. Myasthenia crisis may be caused by a lack of medicine or by other factors, such as a respiratory infection, emotional stress, surgery, or some other type of stress. The airway may become blocked because of weakened throat muscles and build up of secretions. Breathing may become shallow or ineffective. This is a condition of extreme muscle weakness, particularly of the diaphragm and chest muscles that support breathing. The most serious complications of myasthenia gravis is a myasthenia crisis. What are the complications of myasthenia gravis? A blood product that helps decrease the immune system’s attack on the nervous system. A procedure that removes abnormal antibodies from the blood and replaces the blood with normal antibodies from donated blood. However, it reduces symptoms in more than 70% of people who do not have cancer of the thymus, possibly by altering the immune system response. The role of the thymus gland in myasthenia gravis is not fully understood, and the thymectomy may or may not improve symptoms. This is surgical removal of the thymus gland. Anticholinesterase medicines, steroids, or medicines that suppress the immune system’s response (immunosuppressive) medicines may be used. In more severe cases, help may be needed for breathing and eating. Most people with this condition can improve their muscle strength and lead normal or near normal lives. The goal of treatment is to increase muscle function and prevent swallowing and breathing problems. Early detection is the key to managing the condition.

These tests are done to check for conditions that run in families. These tests look for antibodies that may be present in people with myasthenia gravis.

This blocks a chemical needed to stimulate muscle contraction.Ī temporary form of myasthenia gravis may develop in the fetus when a woman with myasthenia gravis passes the antibodies to the fetus.
