How to prepare for a doctor's appointment: turn years of notes into one page

By Paul Mederos, founder of Kasane · Updated

To turn years of health notes into something a doctor can use, write one page that leads with your main concern, then gives a short dated timeline, what you've tried and how it went, your medicines and supplements, and your three most important questions. Keep your full notes behind it in case the doctor wants detail.

If you've been writing things down for a long time, you already have the hard part. The problem is that a notebook, a notes app or a folder of lab PDFs is written for you, in the order things happened. A doctor needs the same facts in the order that answers their questions.

A notebook is written in time order, for you. The summary keeps the same facts, in the order a doctor's questions come, and says so plainly when the notes don't tell you something, like how often or whether you still take it.

Why one page

The National Institute on Aging's advice is to "be clear and concise when describing your symptoms" (NIA), and to put your questions in order and ask the most important ones first (NIA). A page you can hand over does both. It also means you won't spend the visit scrolling for the one detail that matters.

Step by step

  1. Gather everything in one place. Your notes, any lab results, past visit summaries, and a list of every medicine and supplement you take. AHRQ suggests bringing "all the medicines you take" to the appointment, because doses are easy to misremember (AHRQ).
  2. Lead with your main concern. Write it in one line, in your own words. If other things are going on too, list them briefly underneath so you and your doctor can decide what to cover.
  3. Build a short timeline for that concern. When it started, what was happening in your life then, and the handful of moments that changed things: a flare, a new medicine, a test, a diagnosis. Dates can be approximate, but write them down.
  4. Describe the pattern the way doctors ask about it. The NIA lists the questions: when it started, what time of day it happens, how long it lasts, how often, whether it's getting better or worse, and whether it stops you doing your usual things (NIA).
  5. List what you've tried. Each change, roughly how long you tried it, and what happened, including "no clear effect." This is often the most useful part of years of notes, and the part that's hardest to remember in the room. If you're still testing something, here's how to tell whether a change is working.
  6. Add what doctors routinely need. Medicines and supplements with doses, allergies and what happened when you reacted, relevant family history, and any previous test results.
  7. Write your top three questions, most important first.
  8. Date it, and keep your originals. The summary points to your notes; it doesn't replace them.

For gut symptoms, the gastroenterologist version adds bowel habits and a warning-signs checklist.

Using an AI assistant to help

An AI assistant can be a good first pass at sorting years of notes into this template, especially if they're long or scattered. Here's a prompt you can paste in with your notes:

Turn my health notes below into a one-page summary for my doctor. Use these sections: last updated, main concern (one line), timeline (three to five dated moments), pattern, better or worse with, impact, tried so far (change, how long, what happened), medicines and supplements, allergies and family history, previous tests, and my top three questions. Next to every line, add the date and a short quote from my notes that it came from. If a date or detail is unclear, mark it as uncertain instead of guessing. Don't add anything that isn't in my notes.

A few checks help you catch mistakes:

  • Check the tool's privacy practices before you upload medical records, and remove identifiers it doesn't need.
  • Ask it to keep the date and a short quote from your notes next to each line, so you can see where every point came from.
  • Verify your current medicines and doses separately, from the bottles or your pharmacy, rather than from old notes.
  • Keep uncertain dates or diagnoses labeled as uncertain.
  • Read the result against your originals before you print it. A summary can drop a detail or state something more firmly than your notes did, and you're the one who'll be asked about it.
Tried so farNo dairy for 3 weeks: no clear effect
From your note, Sep 2024"Off dairy for 3 weeks. No real difference."
Ask an AI assistant to keep the date and a short quote from your notes next to every line it writes. Then each point can be checked against what you actually wrote, before the page goes to your doctor.

After the visit

Add the date, what the doctor said, any tests ordered and the plan to your notes the same day, so your next summary starts from there. In the US, "you have the right to see and get copies of your health information," and if your doctor offers a patient portal, you may be able to view and download it there (HHS).

Don't wait for the appointment if

Some symptoms need help before you finish any summary:

  • Call 911 or go to an emergency room for severe difficulty breathing, severe stomach pain that came on suddenly, vomiting blood or something that looks like coffee grounds (NHS), or bleeding from your bottom that won't stop or is heavy, for example if the toilet water turns red or you see large clots (NHS).
  • Get an urgent, same-day appointment or go to urgent care if your stool is black or dark red, or you have bloody diarrhea (NHS).
  • See a doctor soon, rather than waiting for a routine visit, about other blood in your stool or weight loss you can't explain.

Questions people ask

What should I bring to a doctor's appointment?

A one-page summary of your main concern, a list of all medicines and supplements with doses (or the bottles themselves), any recent test results, and your questions written down with the most important first.

Should I make a list of symptoms for my doctor?

Yes. Writing your symptoms and questions down beforehand is standard advice from AHRQ and the NIA. Note when each symptom started, how often it happens, what makes it better or worse, and how it affects your day, and put the most important first.

How do I explain years of symptoms to a doctor?

Lead with the main concern in one line, then give a short timeline with dates, describe the pattern (how often, when, how long, better or worse), and list what you've already tried and how it went. Keep your detailed notes with you in case they want more.

Can ChatGPT summarize my medical history?

It can help organize long notes into a summary. Check the tool's privacy practices first, ask it to keep dates and short quotes from your notes next to each point, and check every line against your originals before you rely on it.

How long should a summary for my doctor be?

One page is a good target. It's enough to cover the main concern, what you've tried and your questions, and short enough to read at the start of a visit.
