Monica Seles Announces Myasthenia Gravis Diagnosis

2026-06-23 · Monica Seles · Player Focus

Monica Seles announces her diagnosis with myasthenia gravis, a condition that causes muscle weakness and fatigue.

She first noticed symptoms in 2019 while swinging her tennis racket and seeing double.

Seles told The Associated Press she had been experiencing double vision and arm weakness, which led to a diagnosis three years ago.

The 51-year-old tennis athlete is speaking out now to raise awareness about the disease.

Myasthenia gravis affects 150 to 200 people per million globally, with no cure, but treatment can help ease symptoms.

Seles' diagnosis has forced her to adjust her daily life and tennis routine.

She can still play tennis and pickleball, but some days are more challenging than others.

Seles is living a "new normal" since her diagnosis and is focused on managing her condition.

She walks her dogs and spends time with people who understand what she is coping with.

Seles' history in tennis is notable, with a career record of 684-167 and a No. 1 ranking in 1991.

She was inducted into the Tennis Hall of Fame in 2009.

And despite her diagnosis, Seles remains positive and determined to raise awareness about myasthenia gravis.

But she acknowledges that it's a difficult journey, and she is still adjusting to her new reality.

So Seles is taking things one day at a time, focusing on her health and well-being.

Her story serves as an inspiration to others who may be struggling with similar conditions.

Seles' experience with myasthenia gravis is a testament to her strength and resilience as a person and an athlete.
