Water (100 Ml) and Water (100 Ml)

Verify the reading: plain water should not raise glucose, so recheck with a clean, dry finger or confirm with a second measurement.

Review possible non-food contributors around the time of the spike, such as stress, illness, poor sleep, dehydration, exercise, or medication timing.

Avoid drinking water immediately after handling fruit, sweets, lotions, or glucose products until hands are washed and fully dried, as residue can distort finger-stick results.

Stay hydrated consistently throughout the day rather than waiting until you are very thirsty; dehydration can concentrate blood glucose readings.

If you use continuous monitoring, confirm unexpected spikes with a finger-stick test and note whether pressure on the sensor or sensor lag may be involved.

Discuss repeated unexplained medium spikes with your clinician, especially if they occur with symptoms or persist over several days.
