Josh Allen says he throws up before almost every game because of nerves, adrenaline, and as part of a quirky pregame ritual he now leans into rather than something caused by illness.

The Basic Reason

  • Allen has explained that vomiting is just part of his routine on game days and “basically happens every game,” especially if he doesn’t “get it out” before kickoff.
  • He has not linked it to being sick; instead, it’s framed as a mix of pregame anxiety and how his body reacts to the intensity and emotion of NFL games.

His Own Explanation

  • In interviews and features, Allen has said his three must‑do gameday habits are to “throw up, listen to my playlist and drink water,” making the vomiting a deliberate, expected step rather than an accident.
  • He has also described it in motivational terms, likening it to a “primal” prep and playing on the idea that “a hungry warrior fights harder,” suggesting he’s turned an anxious reaction into a psychological edge.

Not A Medical Disclosure

  • Allen has not given a detailed medical reason, like a diagnosed condition; public comments stay general, focusing on nerves, adrenaline, and ritual.
  • Media coverage and sideline clips show it as a long‑running habit that teammates and coaches simply accept as part of how he gets ready to play at a high level.

TL;DR: Josh Allen throws up before games because his body reacts to pregame nerves and adrenaline, and he’s turned that into a regular ritual— not because of a known illness.
