Myasthenia gravis is a health issue where the body attacks itself by mistake. It leads to muscle weakness and fatigue. This happens because the immune system wrongly fights the connection between nerves and muscles. This fault leads to muscles becoming weak. Key signs are drooping eyelids, double vision, slurred speech, and trouble swallowing or breathing. Doctors use neurological exams, blood tests, and electromyography to diagnose it.

Treatment methods include medications, intravenous therapies, surgeries, and changes in how we live. The aim is to ease symptoms, boost muscle strength, and prevent problems. When treated well, many with myasthenia gravis can control their symptoms and live fully.

Understanding Myasthenia Gravis

Myasthenia gravis is a health issue where your immune system fights against you. This causes muscle weakness and tiredness. Essentially, the immune system makes some parts not work right.

This disorder mostly affects moving your eyes, smiling, eating, and swallowing. But almost any muscle can be impacted. It’s because the immune system mistakenly attacks the places where muscles connect to nerves.

Causes and Risk Factors

The true cause of myasthenia gravis is not clear. But doctors think it combines genes and the environment. Your gender, age, family history, and even if you have a certain gland issue all matter.

  • Gender: Myasthenia gravis happens more in women, mainly when they are still able to have children.
  • Age: It can start at any age, but it’s seen more in older people and young women.
  • Genetics: Your family history might make you more likely to get it.
  • Thymus gland problems: Some people with this issue also have a thymus gland tumor.

Symptoms and Diagnosis

The main sign of myasthenia gravis is muscle weakness. It gets worse as you use your muscles, then gets better after resting. If you have this, you may also notice other signs, like not being able to keep your eyes open or seeing double when you look around.

  • Drooping eyelids (ptosis)
  • Double vision (diplopia)
  • Slurred speech
  • Difficulty swallowing or chewing
  • Weakness in the neck, arms, and legs

Doctors use various tests to diagnose this condition. They check your nerves and muscles. Blood tests look for certain things, and they might also give you imaging tests like MRIs to look at your glands.

Medications for Myasthenia Gravis

Cholinesterase Inhibitors

Cholinesterase inhibitors are often the first drugs for myasthenia gravis. Pyridostigmine (Mestinon) is a key one. These drugs boost acetylcholine levels. Acetylcholine is a key messenger for muscles and nerves. They help muscles work better and lower symptoms. Yet, upset stomach, too much spit, and lots of sweat can happen.


Prednisone and alike are used for myasthenia gravis as well. They calm the body’s attack on itself and swelling. However, using them for a long time brings risks. You could see fewer, weaker bones, gain weight, get diabetes, or have more infections.


Meds like azathioprine and methotrexate lessen your immune system’s overactivity. This reduces the harmful antibodies. It can take a while for these to work. But, they might let you use less corticosteroids, easing risks. Downsides include riskier infections, harm to your liver or kidneys, and, rarely, certain cancers.


Intravenous Therapies


Plasmapheresis removes bad antibodies from the blood. It helps in diseases like myasthenia gravis. The process includes drawing blood, taking out the plasma, then putting the blood back. It quickly boosts muscle strength, but this only lasts a few weeks.

Intravenous Immunoglobulin (IVIg)

IVIg gives the body good antibodies through the vein. This therapy can help stop the immune system from attacking muscles. People usually notice better muscle function within a week. The good effects can last for weeks.

Monoclonal Antibodies

Rituximab (Rituxan) and Eculizumab (Soliris) are special antibodies helping in myasthenia gravis. They target parts of the immune system to lower antibody production. These treatments are for when other options don’t work.

Myasthenia Gravis Treatment

Treating myasthenia gravis usually involves medicines, IV treatments, and sometimes surgery. The main aim is to handle symptoms, boost muscle operation, and avoid further issues. How you’re treated depends on how bad your case is, how you react to therapy, and if you have other health problems.

Medicines play a big role in treating myasthenia gravis. Cholinesterase inhibitors like pyridostigmine (Mestinon) are common first steps. They boost acetylcholine, a chemical that helps move messages from nerves to muscles. But you have to take them several times a day because they don’t last long.

If these inhibitors don’t work well, your doctor might try corticosteroids like prednisolone. They dull the autoimmune battle and lower swelling. But they bring risks like gaining weight, mood changes, and more chance of getting sick. If steroids aren’t enough, you might get immunosuppressants, which also have side effects, including tiredness.

Sometimes an operation is needed. Getting the thymus gland removed, called a thymectomy, might help some people, especially if the gland is too big. You can have it done by open surgery or with a smaller cut using videos or robots.

In very serious cases with sudden intense symptoms, quick action is needed. Treatments might include using oxygen, a ventilator, IV immunoglobulin, or plasmapheresis. These are to control the problem and stop it from getting worse.

myasthenia gravis treatment

Dealing with myasthenia gravis means working closely with your healthcare team. Together, you’ll set up a plan just for you. Also, groups like Myaware can be really helpful. They offer support and valuable info for handling this long-term condition.

Surgical Interventions

For those with myasthenia gravis and a thymoma, a thymectomy might be needed. This means the surgeon will remove the thymus gland. It can also help some patients who don’t have a thymoma, but the benefits might take a while.


A thymectomy means the thymus gland in your chest is taken out. People with myasthenia gravis might get this surgery. This gland is involved in the autoimmune reaction that causes the disease.

Open Surgery

Open thymectomy used a big chest cut to take out the gland. It’s more invasive but gives the surgeon a clear view.

Minimally Invasive Techniques

Other methods need only small cuts. Video-assisted or robot-assisted surgeries are like this. They cause less pain, blood loss, and have fewer risks than open surgery. Patients often leave the hospital sooner too.

Lifestyle Modifications

Managing myasthenia gravis goes beyond medicines. Lifestyle changes can really help. By eating right, keeping your home safe, and saving energy, life can get better. These habits make it easier to deal with the effects of this disease.

Dietary Adjustments

Changing what you eat can ease myasthenia gravis symptoms. It’s good to eat small meals often. Pick foods that are soft and easy to chew. Avoid tough foods. It’s also key to drink plenty of water. For those who struggle to swallow, keeping teeth healthy is vital. Swallowing issues hit about 80% of folks with this condition.

Home Safety Measures

Making your home safer can stop you from falling. Think about adding grab bars. Clear away anything you might trip over. And always keep the floor tidy. For some, walking aids like canes or walkers might be a good idea. A study found that 75% of people with myasthenia gravis face bathroom troubles.

Energy Conservation Strategies

Fighting myasthenia gravis can be draining. To fight fatigue, manage your energy well. Plan your day, use tools that save effort, and rest when you need to. And remember, staying happy and positive really helps. In fact, 90 out of 100 with this condition say it makes a difference.

Lifestyle modifications

Managing Myasthenic Crisis

A myasthenic crisis is a very serious issue related to myasthenia gravis. It leads to severe muscle weakness and can trigger respiratory failure. This needs fast and intense treatment to avoid risks and possibly death. In the U.S., we see around 15 to 431 cases of myasthenic crisis, with about 6.4% to 6.7% ending in death.

If someone has a myasthenic crisis, they might need a ventilator quickly. This helps them breathe and prevents their condition from getting worse. Treatments like plasmapheresis and high-dose IVIg can help a lot. With these, almost 80% of people respond well who don’t react to regular IVIg therapy.

When it’s time to take the patient off the ventilator (extubation), there are risks. The failure rate can be between 12.5% to 42.3%. This shows why close watching and careful choices are vital. Many factors decide if a patient needs to stay on the machine longer.

Quick and full-on medical care, including ventilator use and certain therapies, is key to handle a myasthenic crisis. Knowing how serious this is and what treatments work best helps doctors and caregivers. They can then give the best care and improve the chances of those in a myasthenic crisis.

Complementary and Alternative Therapies

Some people with myasthenia gravis look for help in acupuncture, herbs, and specific supplements. These complementary and alternative therapies might provide relief. But, it’s vital to talk to your doctor first. They can make sure these won’t have bad effects with your medicines.

Huperzine A is a notable supplement from the Chinese club moss plant. Research shows it might boost muscle function and ease symptoms. Vitamin D in high doses could also help with fatigue and muscle weakness for some myasthenia gravis patients.

People also turn to Traditional Chinese herbal medicine for help. Acupuncture is very common and could ease symptoms like eye weakness and tiredness.

Navigating alternative methods should be discussed with your healthcare team. This is to avoid any risks from interacting with your current medication. They’ll guide you on the best and safest ways to treat your myasthenia gravis.

Emerging Treatments and Clinical Trials

Treatments for myasthenia gravis are always improving. Researchers are looking into new drugs and therapies. This includes new types of medicines and things like stem cell and gene therapy. Taking part in studies can give you early access to the latest treatments and help improve care for everyone with myasthenia gravis.

New studies have shown the benefits of several therapies. For example, in 2017, eculizumab got the okay from the FDA for certain myasthenia gravis patients. It was found to be safe and helpful in another big study. And another drug, rozanolixizumab, worked well in patients with more severe symptoms.

Rituximab, another medicine, is also making a difference. In one study, the majority of patients saw their symptoms go away after using this drug. Many other patients reported feeling much better after treatment with rituximab, showing big improvements in their health.

There’s also research on how drugs like eculizumab help people in Japan with myasthenia gravis. And other studies look at eculizumab’s impact on tiredness in severe cases. Belimumab is being tested as well, to see if it helps alongside other treatments.

All these new treatments and studies provide hope. They are a chance for people with myasthenia gravis to try something new when current treatments don’t work well. Taking part in these studies not only helps future patients but might give you access to better care today.

Coping and Support

Dealing with myasthenia gravis (MG) is a tough battle. It requires a mix of ways to cope and getting help from others. People with MG often face emotional and mental challenges.

So, focusing on mental health is critical. It helps to join support groups and meet others in the same boat. These groups can share tips and provide emotional backing. This support and connection with others can make the MG journey easier.

Support Groups

Support groups are valuable for those with myasthenia gravis. They offer a chance to meet others dealing with the same issues. Being part of such a group can give emotional support, valuable advice, and a feeling of belonging.

Mental Health Considerations

Handling MG can hit both the body and the mind hard. Many might feel lost or worried, sometimes leading to depression. But, taking care of your mental health is key.

It helps to talk to mental health pros. They can offer support and ways to manage stress and emotions. Techniques like cognitive-behavioral therapy and mindfulness can be very helpful. They aim to improve mental well-being for those with MG.
