Overview

Diarrhea records reported symptom severity in Apple Health. Its category value is not a stool count, fluid-loss estimate or laboratory result.

What do the severity labels mean?

CodeLabelInterpretation
0unspecifiedSeverity was not specified
1notPresentExplicitly reported absent
2mildSubjectively mild
3moderateSubjectively moderate
4severeSubjectively severe

Apple uses HKCategoryValueSeverity for this type. Unspecified and notPresent mean different things. The codes identify labels; an average such as 2.5 is not a symptom measurement or a validated clinical score. Missing entries are unknown, not automatically notPresent.

Can these entries show how often diarrhea occurred?

Several records may be updates to the same period of illness, while one record may summarize a whole day. Without an explicit diary, record count cannot establish stool frequency. The type also does not encode stool consistency, blood, urgency or infection status. Keep these distinctions visible when summarizing a history.

Nausea, Vomiting and Abdominal Cramps can be recorded separately. Their presence on the same day describes co-reported symptoms, not a confirmed stomach infection. A Dietary Water history can show what was logged as intake but cannot calculate fluid lost through diarrhea or demonstrate adequate hydration.

How should repeated entries be read?

This is a logged observation, with no guaranteed recording frequency. Gaps between start times describe the saved logging history, not symptom-free intervals. Source changes, retrospective entry and overlapping records can change the apparent pattern. A sample's start and end describe the interval the source saved; they do not establish a distinct clinical episode or continuous symptom duration.

When summarizing a history, keep the category labels, reporting dates and source visible. Count explicitly absent observations separately from missing days. Review unexpected labels or repeated overlapping records before treating them as changes in health.

When does this need medical attention?

Seek prompt medical advice for bloody stools, severe abdominal pain, dehydration or persistent diarrhea. Children and people at higher risk may need earlier assessment. A mild entry or an empty timeline does not establish that illness is safe to manage without help.

What can the available example establish?

No records of this type were found in the database research window, so severity frequencies, source differences and logging patterns could not be measured. This HealthKit type is not listed in the current PulsHealth sync catalog. Database coverage therefore cannot establish whether corresponding records exist in Apple Health, and an empty timeline does not establish symptom absence.
