Young, Healthy—and Hit by a Stroke: Bethany Fonseca’s Wake-Up Call for Gen Z and Millennials

Stroke risk surges among Millennials and Gen Z as hypertension, lifestyle and hormonal factors converge in increasingly younger patients

MBT Desk

At age 27, Jacksonville, Florida resident Bethany Fonseca suffered a stroke on October 2011, that stunned her and highlighted a growing health concern among young adults. She collapsed at home after experiencing dizziness, numbness in one arm and was rushed to Baptist Medical Center South. Doctors initially was going to discharge her after basic tests, but she insisted on more checkups. They finally discovered her stroke, which occurred just millimeters from her brain stem. They linked it to three combined risk factors: use of oral birth control, a heart condition known as patent foramen ovale (PFO), and a history of migraines.

During recovery, Fonseca faced right-side weakness and engaged in intensive physical therapy. Her regimen included exercises adapted to carry the weight of her twins in Brooks rehabilitation. After a week in hospital and eight days of rehabilitation, she regained mobility and returned to driving within a month. She still feels weak on her right side but admits being luckier than most and highlights the importance of increasing awareness about stroke symptoms and prevention.

Fonseca credits her survival in part to her dog, Koda, who repeatedly nudged her as she crawled toward the door to unlock it for paramedics. “Every time I wanted to give up, he nudged me again. If it wasn’t for him, I wouldn’t be here,” she said to USA Today.

Emergency medical technicians initially underestimated her condition and even had her walk down the stairs of her apartment despite her severe symptoms. At the hospital, doctors prepared to discharge her before a neurologist finally performed a stroke assessment and confirmed the diagnosis.

Bethany later joined the American Heart Association and American Stroke Association’s awareness campaigns, stressing that “stroke is not just an older person’s disease—it can happen to anyone, no matter your age or race.” She uses her platform to advocate for knowing the warning signs, such as sudden dizziness, vision changes, weakness or numbness on one side of the body, and severe headaches.

Medical experts point out that while oral contraceptives are generally safe, they can increase clotting risk in women who already have other stroke risk factors such as migraines, smoking, or heart defects. According to her rehabilitation assistant, she was one of at least four women he had treated for strokes linked to birth control in a decade.

Strokes on the Rise Among Younger Adults

Regional and Global Trends

Medical professionals increasingly describe strokes as not just an older adult issue. In the U.S., strokes among adults aged 18–44 increased by 14.6 percent, and by 15.7 percent in those aged 45–64, based on CDC data comparing 2011–13 to 2020–22.[1] Another report notes that between 1993 and 2015, stroke rates in people aged 20–44 nearly doubled. [2]

Contributing Risk Factors

Classic cardiovascular risk factors: high blood pressure, obesity, diabetes, smoking, and sedentary lifestyles are alarmingly prevalent in younger cohorts, contributing significantly to the trend. [3] Migraines, especially with aura, combined with PFO can multiply stroke risk, sometimes more than doubling it.

Hormonal birth control also carries a known risk. Research indicates users have a 1.6 times higher risk of ischemic stroke, with users typically younger and showing different clinical patterns such as fewer traditional factors but more lipid abnormalities and undetermined causes. Importantly, long-term outcomes after stopping contraceptives were more favorable, with fewer recurrent strokes. [4]

Clinical Implications and Symptoms

Strokes in younger adults may not appear as severe initially and often go unrecognized. Neurologists emphasize distinguishing symptoms early using the BE FAST acronym (Balance, Eyes, Face, Arm, Speech, Time) and seeking immediate care, as timely treatment affects outcomes significantly. [5]
