  • Learning Outcomes

    • On successful completion of this module, candidates will be able to:

      Vomiting Vs regurgitation

      • Differentiate vomiting from regurgitation in dogs and cats using targeted history-taking and observation of episode characteristics.
      • Select key physical examination priorities that help localise disease to the oesophagus, stomach, or extra-gastrointestinal systems.
      • Justify an initial diagnostic direction based on timing (post-prandial vs fasting), contents, frequency, and associated clinical signs.
      • Recognise red flags (e.g., projectile vomiting, haematemesis, collapse) that warrant urgent stabilisation and escalation of care.

      Diagnostic tools

      • Formulate a rational diagnostic plan for vomiting patients, selecting appropriate baseline and advanced tests.
      • Interpret haematological and biochemical abnormalities in the context of vomiting and use them to refine diagnostic hypotheses.
      • Evaluate the role of abdominal point-of-care ultrasound (POCUS) in vomiting cases, including indications, limitations, and common decision points.
      • Select appropriate diagnostics when toxicological exposure is suspected, and explain how test results influence clinical decision-making.

      Approach to the vomiting patient

      • Generate a prioritised differential diagnosis list for acute vomiting that integrates signalment, history, and clinical presentation.
      • Plan a structured triage and stabilisation approach for vomiting patients, including analgesia, antiemetic use, and fluid therapy principles.
      • Formulate a coherent outpatient vs hospital-based management plan, with clear criteria for admission, monitoring, and reassessment.
      • Identify when vomiting may represent systemic disease and adjust diagnostic priorities accordingly.
      • Communicate a stepwise plan to owners, including safety-netting, expected response to therapy, and escalation triggers.

      Gastric and intestinal foreign bodies

      • Recognise clinical patterns and risk factors that increase suspicion for gastric or intestinal foreign bodies in dogs and cats.
      • Integrate history, examination findings, and imaging results to prioritise mechanical obstruction within the differential diagnosis list.
      • Plan an evidence-informed management pathway, including criteria for conservative management versus endoscopic or surgical intervention.
      • Outline practical monitoring parameters and decision points for reassessment to prevent deterioration and delayed intervention.

      Gastric ulcerations in dogs and cats

      • Identify common causes of gastric ulceration in small animals and link them to case presentation and risk assessment.
      • Recognise clinical and laboratory features consistent with gastrointestinal bleeding and explain their implications for case severity.
      • Design an appropriate treatment protocol for suspected or confirmed gastric ulceration, including gastroprotectants and supportive care.
      • Plan monitoring strategies to evaluate response, identify complications, and guide safe step-down or discharge planning.

      Addison’s disease

      • Recognise when vomiting may be a manifestation of hypoadrenocorticism and prioritise it appropriately within differentials.
      • Interpret key clinicopathological abnormalities suggestive of Addisonian crisis and explain their relevance to immediate management.
      • Plan an urgent diagnostic and stabilisation approach for suspected Addisonian patients, including appropriate test selection.
      • Formulate an initial management and monitoring plan that supports clinical stabilisation and guides onward care.

  • Diagnostic Tools

    • This section builds a structured approach to diagnostics in vomiting patients, integrating laboratory testing, imaging, and point-of-care ultrasound. Learners practise interpreting haematology and biochemistry in context, and explore how results refine differentials. The section also addresses when to consider toxicity and how diagnostic choices influence safe, timely management.

      • Virtual Journal Club

        This Virtual Journal Club examines a cross-sectional study comparing abdominal radiography and ultrasonography for diagnosing small-intestinal mechanical obstruction in acutely vomiting dogs. The aim is not to memorise performance figures, but to practise critical reading: what the test results really mean in clinic, when uncertainty is acceptable, and when it should trigger escalation.
