Myopathy is a neuromuscular disorder in which the muscle fibers do not function properly. The common myopathy symptoms are muscle weakness, muscle pain and tenderness, muscle cramps, fatigue, lack of energy. There are numerous myopathy causes and each has its own specific name, cause, diagnostic tests and treatment. However, there are no effective myopathy treatment that can cure myopathy. The myasthenia gravis symptoms can be improved or can be prevented from worsening.
Myasthenia gravis is a autoimmune disease which occurs due to the weakening of skeletal muscles. The neuromuscular disorder occurs due to the impaired communication between nerve and muscle cells. It prevents the muscle contraction and thus causes muscle weakness.
What are the symptoms of myasthenia gravis?
The major myasthenia gravis symptoms is voluntary skeletal muscle weakness. Without the proper response to nerve impulses, muscle contraction fails and thus muscle weakens. Some of the common symptoms of MG are:

What causes myasthenia gravis?
The myopathy causes is still unclear. According to some researchers, when immune system attack healthy tissue autoimmune disorders occur. Antibodies mistakenly attack the neuromuscular junction instead of attacking foreign, harmful substances in the body. The damaged neuromuscular membrane reduces the effect of neurotransmitter substance acetylcholine which causes the muscle weakness.
How is myasthenia gravis diagnosed?
Treatment options for myasthenia gravis
Myasthenia gravis treatment involves managing the symptoms and controlling the activity of immune system.
There are corticosteroids and immunosuppressants that can be used to suppress the immune system. These can help to reduce the abnormal immune response which occurs in MG.
In addition, cholinesterase inhibitors such as pyridostigmine (Mestinon) can enhance the communication between nerves and muscles.
Thymus gland removal
Thymus gland removal in patients with MG reduces muscle weakness. According to the Myasthenia Gravis Foundation of America, about 10 -15 percent of people with MG develop a tumor in their thymus. The removal is the appropriate solution as it may become cancerous.
The process involves the removal of harmful antibodies from the blood which causes muscle weakness. Removing the harmful antibodies result in an improvement in muscle strength.Plasma exchange is beneficial before surgery or during extreme muscle weakness.
Intravenous immune globulin
The blood product Intravenous immune globulin (IVIG) is used to treat autoimmune MG.
Following few lifestyle changes can help reduce Myasthenia gravis symptoms :
Taking adequate rest helps to minimize muscle weakness.
Avoid stress and heat exposure as they can worsen symptoms.
Though these myasthenia gravis treatment cannot cure MG. However, they can simply improve the symptoms. Make sure to check with your doctor before taking any type of medication.
