I should have asked in my first reply, which code or library you use
Do you use this ?
I think the delay is for the conversion time of the INA226.
In that code are three wrong lines, the Wire.requestFrom() should not be encapsulated by Wire.beginTransmission and Wire.endTransmission, and the while(!Wire.available()) is wrong.
Those are common mistakes, but only made by people who don't understand how to use the Wire library.
