Myasthenia Gravis

Myasthenia gravis is weakness and rapid fatigue of the muscles that are under your voluntary control. This occurs due to a breakdown in communication between the nerves and the muscles. There is no cure for myasthenia gravis and it can affect people of any age. However, it is more common in women who are younger than 40 and men who are older than 60.


Neurotransmitters are responsible for the communication between your nerves and your muscles. Those who have myasthenia gravis have an immune system that produces antibodies to block or destroy your muscles’ receptor sites. Because of fewer receptor sites, your muscles can’t receive as many nerve signals, which results in muscle weakness. The thymus gland is thought to be responsible for maintaining the production of antibodies that block acetylcholine.


The main symptom of myasthenia gravis is muscle weakness as the affected muscle is repeatedly used. Symptoms improve with rest, so muscle weakness may come and go. Over time, myasthenia gravis symptoms may progress and get worse. Symptoms typically reach their worst within a few years after the onset of the disease. Certain muscle groups are affected more than others, including:

  • Eye muscles: more than half of myasthenia gravis sufferers experience drooping of one or both eyelids or double vision.
  • Face and throat muscles: due to affected face and throat muscles, you may experience hoarse voice, difficulty swallowing, problems chewing, and limited facial expressions.
  • Neck and limb muscles: You may experience weakness in your neck, arms and legs, however, this usually happens in conjunction with weakness in other parts of your body such as your eyes, face or throat.

It is also important to note factors that can worsen myasthenia gravis, including fatigue, stress, illness, and some medications, such as beta blockers.

Medical Marijuana and Myasthenia Gravis

Research suggests that cannabinoids can help regulate multiple different levels of neuronal communications, including the formation of new neurons. The use of medical marijuana also helps the patient’s muscles to relax and function in an operational matter. The active ingredients found in medical marijuana can also help improve other side effects of myasthenia gravis, including stress, anxiety and chronic pain.
