What is causing my spikes?

39 times in 14 days — about 3 a day. 14 started in the morning (5 AM–11 AM), 10 in the afternoon, 14 in the evening (5 PM–11 PM), and 1 overnight.

14 days of FreeStyle Libre 3 readings, Sep 1 – Sep 14, 2026. A spike here is a climb of at least 30 mg/dL from where your glucose had been sitting. A new sensor tends to read low for its first 24 hours, so those are shaded.

How high, and for how long?

What is causing them?

You wrote 5 notes, and 4 of the 39 spikes have a food note beside them. Those are the only spikes a cause can be read from so far. In 2 of them, glucose was already climbing before the note was written, so the food came first, by an amount nobody recorded.

1

A food tap, with no words

Tue Sep 1 · 10:57 AM. Glucose began climbing at 10:58 AM, as you wrote the note, from 239 to 275 mg/dL. That was the sensor’s very first reading, so it may have begun earlier.

2

“Lunch : almond and sunflower butters on raisin bread”

Tue Sep 1 · 2:57 PM. Glucose began climbing at 3:03 PM, 5 min after the note, from 139 to 270 mg/dL. This was in the new sensor’s first 24 hours.

3

“Made 2 chicken hotdogs with lavash, made herb salad with lime juice , peach, qoulcom, pistachio, pumpkin seeds”

Tue Sep 1 · 8:12 PM. Glucose began climbing at 7:48 PM, 25 min before the note, from 234 to 303 mg/dL. This was in the new sensor’s first 24 hours.

4

“Going to sleep @11:50”

Tue Sep 1 · 11:50 PM. Glucose was 188 mg/dL then. Only food and drink are matched to spikes; this one is marked on the chart at its time.

5

“Took a cup of whole yogurt with a slice of bread”

Sat Sep 5 · 3:03 PM. Glucose began climbing at 1:38 PM, 1 hr 25 min before the note, from 227 to 304 mg/dL.

The other 35 spikes have nothing written beside them. A note written when you start eating, rather than after, puts the meal exactly against the climb that follows.
