In physiology, body water is the water content of a body, contained in tissuesm the blood, the bones, or elsewhere. Body water is a significant fraction of the human body. Measurement via balance has high fluctuations, depending on the volume of fluid intake and outtake (e.g. sweating).


Body Water is a specific data object to store  body water as percentage of bodymass respectivly bodyweight.


– Documentation of body water percentage
– For evaluations via analytic balance in ambulant settings
– Calculate composition of body weight
– Actual or past measurements
– Exact measurement or Calculation

Not use

– Do not use for estimation
– Do not use for determination of body water due to other methods

Data Model

The Body Water is a measurement object without any specific attributes. See Measurement for more information.


If past measurements should be recorded, the start date must contain the date of measurement.

Parameter Codes

For body water no LOINC code is available, use the CGM LOINC add-on:

Code Code Text
XCG80083-9 Body water percentage


See Measurement Enums for more information.


See Measurement Catalogs for more information.

Update Rhythm

Because various factors can have an effect on Body Water, such as changes in weight or lifestyle, the Body Water object can be updated up to several times a week.

Recommended rules:
– Maximum once a week if body water is constant.
– Maximum once a day if body water varies.


See Measurement Schema for further information.
