Tennis Legend Monica Seles Reveals Myasthenia Gravis Diagnosis

Tennis legend Monica Seles, a nine-time Grand Slam champion and International Tennis Hall of Famer, revealed she has been living with myasthenia gravis (MG), a chronic neuromuscular autoimmune disease, since 2022. Seles first noticed symptoms such as double vision and muscle weakness while playing casually, which made everyday tasks like blowing her hair difficult. The disease causes voluntary muscle weakness and primarily affects young women under 40 and older men over 60 but can occur at any age. After her diagnosis, Seles described the experience as a significant life adjustment, comparing it to previous personal challenges including moving to the U.S. and recovering from a 1993 stabbing incident. She is now partnering with the immunology company Argenx to raise awareness through their Go for Greater campaign, speaking publicly about her condition for the first time ahead of the 2025 U.S. Open. Seles emphasized the importance of public figures sharing their experiences to provide support and visibility for those with MG.
