Why increased thirst is worth watching
A noticeable rise in water intake can point to a number of things worth investigating, kidney function, diabetes, thyroid changes among them. None of that means panic over one thirstier afternoon, but a sustained increase over days or weeks is a genuine, specific signal, not a vague one.
Why it's so hard to judge by memory
Nobody measures a water bowl daily under normal circumstances, and a gradual increase is exactly the kind of change that's nearly invisible day to day. By the time it's obvious enough to notice unprompted, it's often been building for a while.
What else to note alongside it
- Whether appetite has changed at the same time
- Any change in urination frequency or amount
- Weight, since several of the same underlying causes affect both
Why it belongs in the same record as everything else
A single odd observation is easy to dismiss. The same observation sitting next to a weight trend and a few daily log notes stops being easy to dismiss, which is exactly the point of keeping them together rather than scattered across memory. Halo's daily log is built to hold exactly this kind of easy-to-forget detail.
