Tailored Treatment Plans for Complex Medical Conditions

Internal Medicine

The Internal Medicine team specialises in diagnosing and formulating treatment plans for pets with multiple or complex medical conditions. Led by our Board-certified Internal Medicine Specialist, the team utilises a range of diagnostic techniques to thoroughly investigate and develop treatment plans for acute and chronic conditions.


Some commonly seen conditions include:

  • Gastrointestinal disorgers (e.g. inflammatory bowel disease)

  • Haematological (blood) diseases and bleeding disorders

  • Endocrine conditions (e.g. diabetes, Cushing's disease, Addison's disease) 

  • Urinary disorders

  • Kidney disease

  • Heart conditions (e.g. heart murmur, heart failure)

  • Cancer

  • Neurological disorders (e.g. epilepsy, seizures)

  • Liver disease

  • Respiratory conditions (e.g. Feline asthma, chronic bronchitis)


The team also collaborates closely with our other departments such as Surgery and Emergency and Critical Care to ensure the best patient outcome.





Commonly known as an "echo", the echocardiogram is a cardiac ultrasound that scans the heart and nearby blood vessels to check the structure and function of your pet's heart. The procedure is non-invasive and does not require sedation or general anaesthesia.



Using an endoscope to examine the interior of your pet's organs (e.g. bladder, nose, gastrointestinal tract etc.), the vet can assess your pet or perform tissue biopsies and cell sampling. Endoscopies are minimally invasive and done under general anaesthesia. It also leads the way to interventional procedures such as stent placements.


Joint & Spinal Tap

A joint tap or arthrocentesis is performed by inserting a needle into the joint to retrieve fluid for analysis. Spinal taps involve collecting fluids from the spinal cord for analysis. Both procedures are performed under short general anaesthesia.


Bone Marrow Aspiration / Biopsy

Bone marrow aspiration is a procedure to remove a small amount of liquid bone marrow, while a bone marrow biopsy entails retrieving a solid bone marrow sample. This is generally done the determine the cause of abnormalities (extremely high or low) white and red blood cell counts, or of low platelet counts. The procedure is performed under short general anaesthesia.
