oral contraception has been known to make headaches better or worse, so it is important to speak to your doctor about any migraines you have experienced before starting a new medication.
on top of the medication issue, bieber said her doctors believe contacting covid-19 and a long flight led to the formation of a blood clot. a previously undiagnosed heart condition, pfo, allowed the clot to travel to her brain.

bieber also said that an opening in her heart, a patent foramen ovale (pfo), is why the clot travelled to her brain.
a pfo is a small opening between the upper chambers of the heart, allowing a small amount of blood to flow between the right and left atrium, according to
johns hopkins university. pfos are seen after birth, however, two flaps soon develop to create a wall between these chambers. scientists don’t know what causes the wall to form, however, if it doesn’t the pfo can remain into adulthood.
pfos raises the risk of stroke because it creates an avenue through which blood clots can escape the heart into the body’s blood vessels, where it can block blood flow to the brain or other critical organs.
bieber said she had a grade 5 pfo, an opening roughly 12 to 13 millimetres large, and underwent a closure procedure to repair the hole. in this procedure, a small flexible tube called a catheter is inserted into the femoral artery in the groin area and threaded through the artery to the heart. once there, the catheter deploys a small button-like device onto the hole, sealing it shut.
