Depending on the amount and frequency of diarrhea and emesis and the general physical state of the patient , rehydration and electrolyte imbalances can become a serious issue where sips of water aren ' t cutting it anymore . I ' ve also seen cases where admittedly the rehydration would have been possible by mouth judging from the net amount needed , only that even small sips were thrown up again . That usually affected younger patients , though . VD has a wide scope of presentation , and while not every case is an emergency , some justify external hydration plus antiemetics . <| sep |> Damn I forgot to reply , but definitely my friend Trevor <| sep |> TTK . That ' s the phrase I was looking for . And yeah , not looking for another CoD shooter . The TTK during beta completely turned me off the game .
