Small Animal Internal Medicine Services

Small Animal Internists offer a wide array of minimally invasive or non-invasive testing, which includes endoscopy.  Endoscopy is passing a camera into a body cavity.  This could include the GI tract, urinary bladder, nose, etc.  A variety of things can be accomplished with endoscopy including removing foreign material from the esophagus and stomach to collecting biopsy samples for patients that have disease in these locations. 

Frequently, advanced imaging is needed to help examine a body cavity or organ.  Some examples would include ultrasound, CT (computed tomography) and MRI (magnetic resonance imaging) among others. 

Examples of diseases that are frequently treated by internists:

  • Endocrine diseases (diabetes, thyroid disease, pituitary disease, adrenal disease, etc.)
  • Gastrointestinal disease (chronic vomiting, chronic diarrhea, chronic parasite infections, inflammatory bowel disease, etc.)
  • Immune-mediated diseases (hemolytic anemia, thrombocytopenia, lupus, polyarthritis, etc.)
  • Lower urinary tract disease (chronic or recurring bladder infections, prostate disease, incontinence, bladder stones, etc.)
  • Infectious diseases (including bacterial, fungal and viral diseases as well as parasites like Giardia and intestinal worms)
  • Liver disease (portosystemic shunts (liver shunt), hepatitis, yellowing of the skin/eyes (jaundice), gallbladder disease, etc.)
  • Renal (Kidney) diseases (acute and chronic kidney disease, kidney infections, protein-losing kidney diseases, etc.)
