MedicalCondition

MedicalCondition is a MedicalEntity subtype for diseases, injuries, disabilities, disorders, and syndromes. With 17 properties of its own, it is the most detailed medical type in schema.org. The properties cover symptoms (signOrSymptom), treatments (possibleTreatment, drug), anatomy (associatedAnatomy), risk factors (riskFactor), prognosis (expectedPrognosis), and staging (stage).

The type hierarchy is Thing → MedicalEntity → MedicalCondition. Google reads MedicalCondition for health knowledge panels. Important: Google applies strict health content policies. MedicalCondition markup does not bypass medical content review, and Google may require your site to meet YMYL (Your Money or Your Life) quality standards before displaying health-related rich results. The structured data must match peer-reviewed medical information.

signOrSymptom

signOrSymptom takes a MedicalSignOrSymptom object describing observable signs and patient-reported symptoms. Use an array for multiple symptoms. Each entry should have a name and optionally a possibleTreatment. Google displays symptoms in the health knowledge panel's "Symptoms" section.

possibleTreatment and drug

possibleTreatment takes a MedicalTherapy or Drug object. drug takes a Drug object specifically for pharmaceutical treatments. Use possibleTreatment for non-drug therapies (physical therapy, surgery, lifestyle changes) and drug for medications. Google shows treatments in the "Treatment" section of the health panel.

associatedAnatomy

associatedAnatomy takes an AnatomicalStructure or AnatomicalSystem. This connects the condition to the body part it affects. A broken femur references the femur AnatomicalStructure. Asthma references the respiratory AnatomicalSystem.

riskFactor and primaryPrevention

riskFactor takes a MedicalRiskFactor listing what increases the chance of developing the condition. primaryPrevention takes a MedicalTherapy describing how to prevent the condition before it occurs. secondaryPrevention covers preventing recurrence.

stage

stage takes a MedicalConditionStage with stageAsNumber and subStageSuffix. This is for conditions with formal staging systems (cancer stages, kidney disease stages). Do not use it for conditions without established staging.

Common MedicalCondition mistakes

Mistakes that pass validation but silently fail to earn rich results or mislead consumers walking the graph. Avoid these and your markup will be ahead of most sites in the wild.

  1. 01

    signOrSymptom as plain text strings

    Wrong
    "signOrSymptom": ["Stunted growth", "Weight loss"]
    Right
    "signOrSymptom": [{ "@type": "MedicalSignOrSymptom", "name": "Stunted growth" }]

    signOrSymptom expects MedicalSignOrSymptom objects, not plain strings. Structured objects let Google match symptoms to its health knowledge graph and display them correctly in the health panel.

  2. 02

    Inaccurate medical information

    Wrong
    MedicalCondition with incorrect symptoms, treatments, or prognosis
    Right
    Use peer-reviewed medical sources for all medical claims

    MedicalCondition markup may surface in Google health panels. Inaccurate medical information can cause real harm. Source all claims from peer-reviewed literature, WHO guidelines, or established medical references. Google's YMYL policies apply.

  3. 03

    Missing possibleTreatment

    Wrong
    MedicalCondition with symptoms but no treatment information
    Right
    "possibleTreatment": [{ "@type": "MedicalTherapy", "name": "..." }]

    A condition without treatment information is incomplete. Users searching for medical conditions usually want to know about treatments. Google's health panel shows a Treatment section that reads from this property.

About the example data

Post-war childhood malnutrition, the condition that Jane Xoo studied and treated throughout her career. Her 1945 paper described the clinical framework for identifying and treating malnourished children in post-war Copenhagen. The drug references XooPed as a supportive treatment.
