The tourists are up against it in the five-match series after losing back-to-back games in convincing fashion. The feelgood factor of Giles' first game in charge of the limited-overs side - a nine-run win in Rajkot - has long since gone after defeats by 127 runs and seven wickets.
"Changes are something that myself, Alastair Cook and the coaches will talk about," he said, after the team arrived in Chandigarh ahead of Wednesday's fourth ODI.
"We've got options and part of this trip is to look at those options, because we're missing some senior players.
"This group has been very refreshing and what we want to avoid is them just feeling beaten up.
"We have to pick the best team to win the next game of cricket. That will be a hot topic over the next day or two."
But while he accepts the need to run the rule over squad players, which could spell good news for Jos Buttler and Stuart Meaker, he feels a calm head will serve England better than a dressing room tirade.
"Honesty is the important thing. I never, or probably only a couple of times, stamped my feet when I was at Warwickshire," Giles said. "If the coach is on an emotional rollercoaster you end up with a team that is second guessing what your reaction will be if you win or lose - that's not how I want to be.
"You have to analyse where you've gone wrong, look at your personnel, pull those things together and ask "are we getting it right? Is this the right mix? Are they the right people? That's the unemotional way of looking at it.
"The hairdryer treatment works occasionally but not very often, not if you're in it for the long term. If I did that after my third game, there would be a lot of worry."
