# Nutrition Diagnosis

## Content and Modeling

* **Main hierarchies**
  * Terminology for **nutrition diagnosis** is predominantly but not exclusively from the **Clini cal Finding** hierarchy within SNOMED CT. This hierarchy includes concepts related to nutrition-related health issues, conditions, and diagnoses, such as malnutrition, nutrient deficiencies and imbalances.
* **Key Attributes and Value Ranges**
  * A range of attributes is available to represent the properties for concepts within this hierarchy ([Clinical Finding Defining Attributes](/snomed-ct-specifications/snomed-ct-editorial-guide/readme/authoring/domain-specific-modeling/clinical-finding-and-disorder/clinical-finding-attributes-summary.md)); however, the key attributes relevant for nutrition assessment and diagnosis include:
    * **Interprets** : This attribute links the diagnosis to an observable entity being assessed or measured. For example, a diagnosis of '**difficulty swallowing** ' interprets the observation related to a patient's 'ability to swallow', see the example below. This attribute specifies what aspect of nutrition or health is being interpreted within the context of the diagnosis.
    * **Has Interpretation** : This attribute represents the outcome or evaluation of the observation, specifying how the observation is interpreted in relation to the diagnosis. For example, it may link to a **Qualifier Value** such as **Deficient** , **Excessive** , or **Normal** intake, providing a clear description of the interpretation relevant to the nutrition diagnosis.
    * These attributes, **Interprets** and **Has Interpretation** , ensure that each diagnosis is directly linked to the observed data and its interpretation, allowing for precise and standardized representation of nutrition-related diagnoses within SNOMED CT.
* **Templates**
  * As part of the content development process, authoring templates were created to support future content additions and quality assurance of existing and new content in this area. [Nutrition intake (finding) - v1.0](https://conf.spaces.snomed.org/wiki/spaces/SCTEMPLATES/pages/133996630/Nutrition+intake+finding+-+v1.0)

This template ensures that nutrition diagnosis concepts are modeled in a clear, consistent, and clinically relevant manner, supporting effective documentation and interoperability in healthcare settings.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.snomed.org/implementation-guides/ncpt-implementation-guide/4-snomed-ct-content/4.2-nutrition-diagnosis.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
