What to actually write in a daily health log

At nearly every diagnosis, someone hands you a log sheet. Columns for date, time, reading, notes. Most people fill it in faithfully for two weeks and then stop, because a table of numbers with no story attached to them starts to feel pointless. The log was supposed to help, and instead it feels like homework.

A reading without context is half a story

A blood glucose of 178 after lunch tells your doctor something. But 178 after lunch, felt dizzy, had a big pasta meal while visiting family, had been stressed about the drive up tells a different story and opens a different conversation. The number is the same. The usefulness is not.

You do not need to write much

Three to five sentences is enough. Woke up tired even though I slept eight hours. Took metformin with breakfast at 7:30. Reading was 142 before the meal. Walked twenty minutes in the afternoon and felt much better by dinner. That is a useful log entry. It took maybe ninety seconds.

• What time you took any medications, and whether you missed one.
• A reading or two, with a sentence about what you were doing before it.
• Anything that felt different from a normal day, even if it seemed minor.
• How your energy was, in a word or two.
• What you ate or drank if something about that day felt unusual.

Small and regular beats thorough and occasional

A note every day, even a short one, is worth more than a detailed account written from memory the night before an appointment. Memory softens the edges. The 2am headache that turned out to matter gets remembered the next morning as slept okay. The day your reading was unusually low blurs into a week that felt pretty normal.

The best logs are boring most of the time. A flat, unremarkable week is itself useful information for your doctor.

Let plain words do the work

You do not need medical vocabulary. Felt puffy around the ankles is as useful to a clinician as bilateral edema. Chest felt tight when I climbed stairs is better than nothing, even if you are not sure it means anything. Your care team knows how to read plain language. What they cannot do is read nothing.

Cadence accepts notes exactly the way you write them. You can tap in a reading, type a sentence, or say what happened out loud. It connects the pieces over time, so when you do see your doctor, the picture is already there, and the conversation can start somewhere worth starting.
