Ex-Chelsea star Oscar diagnosed after collapsing

Former Chelsea midfielder Oscar is receiving hospital care after a dramatic collapse during pre-season medical assessments.

Diagnosis and Incident Details

The Brazilian football star has been diagnosed with vasovagal syncope, a common condition causing sudden drops in heart rate and blood pressure leading to fainting.

The incident occurred on Friday 14 November 2025 during an interval test on an exercise bike. Medical reports confirm Oscar was unconscious for approximately two minutes after experiencing heart complications.

Medical History and Current Condition

This is not the first heart-related issue for the player. Oscar has been monitoring a cardiac abnormality since it was initially detected in August.

His current club, Sao Paulo, has confirmed the athlete is now stable but remains hospitalised in a cardiology unit. He awaits further electrophysiological testing to determine the next steps in his treatment and recovery.

What is Vasovagal Syncope?

Vasovagal syncope represents one of the most frequent causes of fainting episodes. The condition occurs when the body overreacts to certain triggers, causing a sudden drop in heart rate and blood pressure that reduces blood flow to the brain.

Common triggers include: emotional stress, pain, overheating, dehydration, or prolonged standing. In Oscar's case, the intense physical exertion during testing appears to have triggered the episode.

The football community worldwide has expressed support for the former Chelsea favourite, wishing him a full and speedy recovery.
