How are you supposed to handle going to the doctor if you have a long back log of Issues

I figure it's probably ridiculous to go be seen for one thing at a time but also probably ridiculous to come to a doctor with a huge list of shit you think is wrong with you (while also potentially framing the doctor's view of you as prone to hypochondriasis), so like, i guess the thing to do is make a list and like, see how many of the more urgent things you can discuss in a reasonable time frame? Or is this what "a physical" is for, you get that instead of or prior to mentioning specific concerns?

I haven't seen a doctor in like 10 years so idk how to be a normal person about it
