Endocrine and metabolic disease: obesity, diabetes, thyroid, Cushing, and adrenal concerns

Educational pet-health and visit-preparation reference. Not a diagnosis, prescription, dosage recommendation or substitute for a veterinarian.

Care & observations

  • Weigh the pet regularly, measure food portions, and track water bowl refill frequency without suddenly restricting water.
  • Bring diet, treats, supplements, medications, and weight history to the appointment.
  • For overweight pets, ask for a gradual veterinary weight plan rather than crash dieting.

Seek veterinary care now

  • Collapse, severe weakness, repeated vomiting, severe dehydration, tremors, seizure, trouble breathing, or a diabetic pet not eating.
  • Sudden profound weakness with vomiting or diarrhea in a pet with known adrenal disease risk.

Contact your veterinarian soon

  • Increased drinking or urination, unexplained weight loss or gain, persistent hunger, lethargy, hair loss, recurrent skin or urinary infections, or senior cat behavior change.
  • Before starting supplements, obesity diets, thyroid support products, or home glucose decisions without veterinary instruction.

What to avoid

  • Do not restrict water to reduce urination; increased thirst can signal important disease.
  • Do not adjust insulin, thyroid medication, steroids, or hormone-related medication without veterinary guidance.

MAKE YOUR OBSERVATIONS USEFUL

Bring a clear timeline to your vet

For the changes covered in this guide, note when they started, how often they happen, whether they are worsening and how they differ from your pet’s usual routine. List recent diet changes, medicines, travel or possible ingestion in time order. Add photos or a short video only when it is safe and will not delay care.
