Myasthenia gravis is a disorder that causes weakness in the muscles that are used for movement.

Communication between nerve cells and muscles is impaired. This impairment causes muscle weakness.

According to the Myasthenia Gravis Foundation of America, MG is the most common primary disorder of neuromuscular transmission.

About 20 out of every 100,000 people in the United States have a rare condition called MG. It could be higher because it is underdiagnosed.

There are symptoms and causes of the neuromuscular disorder, and what treatment options are available.

Weakness in voluntary skeletal muscles is the main symptom of MG.

The failure of muscles to contract is usually caused by nerve impulses. The communication between nerve and muscle is blocked if the impulse is not transmitted.

Weakness associated with MG usually gets worse with more activity and improves with rest. Symptoms of MG may present via the following body parts.


Dropping of the eyelid can be caused by the presence of MG. Weakness in your eye muscles is what you may experience.


In addition to facial paralysis, MG may lead to changes in your facial expressions.


You may experience a change in the muscles of the throat.

  • “It’s hard talking.”
  • Difficult breathing
  • swallowing difficulties
  • The voice is hoarse.
  • It is difficult to hold your head up because of your neck weakness.


If you experience symptoms of the chest area being affected by MG, you may be in serious danger.

  • respiratory failure, caused by weakness in the diaphragm and chest muscles that may lead to myasthenic crisis and is considered an emergency

Arms and legs

The muscles in your arms and legs can be affected by the disease.

  • fatigue
  • weakness in your hands and fingers
  • Weakness in your legs.
  • People have problems walking up stairs.

The degree of muscle weakness can change from day to day, and not everyone will have every symptom. If left unaddressed, the symptoms can increase over time.

While the exact cause of autoimmune diseases like MG is unknown, MG may be triggered by a combination of irregular antibodies or problems with the thymus gland, according to the Muscular Dystrophy Association (MDA).

The risks for developing MG may increase with age.

Antibodies and MG

Autoimmune disorders occur when your immune system mistakenly attacks healthy tissue. In MG, antibodies, which are proteins that usually attack foreign, harmful substances in the body, attack nerve cells.

Damage to the neuromuscular membrane reduces the effect of the neurotransmitter substance acetylcholine, which is a crucial substance for communication between nerve cells and muscles. This results in muscle weakness.

The exact cause of this autoimmune reaction is unclear to scientists. The MDA suggests that certain viral or bacterial proteins may prompt the body to attack acetylcholine.

It is possible that having a family history of autoimmune diseases increases your risk of developing an autoimmune disorder.

Thymus gland irregularities

Your immune functions are controlled by your thymus gland, which grows until puberty. The size of the gland shrinks after puberty.

In people with MG, the thymus gland stays large, according to the National Institute of Neurological Disorders and Stroke (NINDS).

It is possible to develop benign or cancer tumors of the thymus, which may interfere with important immune cell production. The enlarged thymus is able to produce antibodies that block acetylcholine.

According to the MDA, about 75 percent of people with MG have thymus gland irregularities (thymic hyperplasia )and another 15 percent have tumors.

Researchers believe that the immune system may be given incorrect instructions by the thymus gland, which may lead to immune cell destruction.

Age plays a role

While MG may develop at any age, it’s most common in people over the age of 40. Women are more likely to be diagnosed as younger adults, whereas men are more likely to be diagnosed at 60 or older.

About 10 to 15 percent of MG cases develop in childhood, but most children achieve remission.

It’s also possible for newborn babies to have a temporary condition called neonatal myasthenia. This occurs when the mother has MG and passes on the antibodies to a fetus. However, neonatal myasthenia is temporary, lasting about 2 to 3 months post-delivery.

Your doctor will perform a physical exam and take a history of your symptoms. They will also do a neurological exam.

This may include:

  • checking your reflexes.
  • Looking for weakness in the muscles.
  • Check for muscle tone.
  • Making sure your eyes are moving.
  • It is necessary to test sensation in different areas of your body.
  • Motor functions can be tested by touching your finger to your nose.

Other tests can help your doctor diagnose the condition.

  • The nerve stimulation test is repetitive.
  • Blood testing for the antibodies.
  • an edrophonium (Tensilon) test
  • imaging of the chest using CT scans or MRI to rule out a tumor

Contact your doctor if you have any unusual symptoms affecting your eyes, face, throat, or overall body movements. You should be especially aware of possible MG symptoms if you’re an older adult with a personal or family history of autoimmune disorders.

If you’ve already been diagnosed and treated for MG, you may go into remission at some point. However, since remission may only be temporary, it’s important to keep track of your symptoms and talk with your doctor if they return.

There is currently no cure for MG. The goal of treatment is to manage symptoms and control the activity of your immune system. Talk with your doctor about the following options.


Corticosteroids and immunosuppressants can be used to suppress the immune system. These medications help minimize the irregular immune response that occurs in MG.

pyridostigmine can be used to increase communication between nerves and muscles.

Thymus gland removal

The removal of the thymus gland is part of the immune system and may be appropriate for some patients. Even benign tumors are removed if they become cancer.

Once the thymus is removed, patients typically show less muscle weakness. Research from 2017 also shows that thymectomy results may be more effective in those who also take prednisone.

Plasma exchange

A plasma exchange is also called apheresis. The process removes harmful antibodies from the blood, which may result in an improvement in muscle strength.

Plasmapheresis is a short-term treatment. The body continues to produce harmful antibodies, and weakness may recur. Plasma exchange is helpful before surgery or during times of extreme MG weakness.

Intravenous immune globulin

IVIG is a blood product that comes from donors. It is used to treat the autoimmune disease. IVIG affects the creation and function of antibodies.

Lifestyle changes

There are some things you can do at home to help.

  • Get plenty of rest to recover.
  • If you’re bothered by double vision, talk with your doctor about whether you should wear an eye patch.
  • Stress and heat exposure can make symptoms worse.

“Treatments can’t cure the disease. You will typically see improvements in your symptoms. It is possible to go into remission, which means treatment is not necessary.”

Tell your doctor about any drugs or supplements you take. Some drugs can make symptoms worse. Before taking any new medication, make sure it is safe.

Left unattended, it may lead to problems. Discuss your risk with your doctor.

Myasthenic crisis

One of the most dangerous potential complications of MG is a myasthenic crisis. It’s estimated that 15 to 20 percent of people with MG will experience at least one episode of this life threatening complication.

During a myasthenic crisis, you may experience severe muscle weakness that leads to respiratory failure, according to the NINDS.

Discuss your risks with your doctor. If you start to have trouble breathing or swallowing, you should go to the emergency room.

Additional autoimmune disorders

Having MG may place you at a higher risk of developing other autoimmune disorders, such as lupus and rheumatoid arthritis. Your doctor will likely recommend regular blood testing to help detect these conditions so you can seek early treatment.

There are a lot of factors that affect the long-term outlook for MG. Some people have mild symptoms while others have more severe symptoms.

Talk to your doctor about what you can do to reduce the severity of your disease. Proper treatment can help limit disease progression and improve your quality of life.
