The average doctors visit lasts around 20 to 30 minutes but some doctors visits may last as long as 40 to 45 minutes.
It depends on if you need to have more tests done or you just need a simple checkup at the doctors office.
Most times when I go into the doctors office for a doctors visit checkup the doctors visit lasts 30 minutes and then I'm done and out of there.
However when I take my kids to the doctors they usually both see the doctor at the same time so it can take as long as an hour in some cases for the checkup to be done.
But that averages out at 30 minutes per child's doctor visit.
But you can expect at least 30 to 45 minutes for one persons doctors visit.
