Share was really, really sick and vomiting and went to the hospital and was there until 5:30 am and got an IV drip:
She came back that night to get silver.
Also there is an interesting anti-doping angle, that we haven't seen mentioned. IVs aren't allowed by WADA unless you get admitted to a hospital. So if you get sick it is better to get really sick and go to the hospital.
WADA says, "Intravenous infusions and/or injections of more than 50 mL per 6 hour period except for those legitimately received in the course of hospital admissions or clinical investigations."
and "Note that if an intervention is part of a clinical investigation or hospital admission, there is no requirement for either an advance or retroactive TUE. The athlete is
nevertheless strongly advised to obtain and maintain and keep a copy of the medical records."
Love to hear scientists chime in how an IV with non prohibited stuff in it could help not sick athletes.
