MG vs MG Recently a campaign has been launched titled MG, which is to raise awareness of the sexually transmitted disease. However, we need to be clear about that this MG is not myasthenia gravis but mycoplasma genitalium, which is a bacterium that can cause inflammation of the urethra in men. Whereas myasthenia gravis (MG) is an autoimmune condition. When you have myasthenia gravis (MG) the antibodies that normally fight infections go wrong and end up attacking the communications system between your brain and your muscle movements. This results in muscle weakness, muscle fatigue and generally making you feel weak. Myasthenia gravis (MG) does not have any link with sexually transmitted infection (STI). Read more about myasthenia gravis's (MG) symptoms, diagnosis and treatments. Myasthenia gravis (MG) and mycoplasma genitalium (MG) are two medical conditions which are completely different and they do not have any link to each other. ‘My Health Passport for Myasthenia' Myaware realises that these two different MG & MG can cause some confusion if members were to go to A&E and mention they have MG. Therefore, we highly advocate to all, who have myasthenia gravis (MG), to keep 'My Health Passport for Myasthenia' with you all the time.
