Diabetes warning signs: thirst, urination, and weight loss

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

Care & observations

  • Record water intake, urination frequency, appetite, body weight, and energy in a simple daily log.
  • Keep meals and activity reasonably consistent until the appointment so changes are easier to interpret.
  • Bring the current medicine list and any home glucose readings; do not change treatment based on a single reading.
  • Make fresh water easy to reach and keep the litter or toilet area clean so urine output can be observed.
  • Ask the veterinarian how diet, monitoring, and follow-up testing should be tailored to this pet.
  • 毎日の記録は、食事や薬の時刻、症状が出た時刻も同じ形式で書くと、受診時に比較しやすくなります。

Seek veterinary care now

  • Collapse, inability to stand, seizures, repeated vomiting, or marked confusion.
  • Severe weakness with refusal to eat or drink needs urgent guidance rather than home treatment.

Contact your veterinarian soon

  • Persistent increased thirst or urination, weight loss despite eating, or recurrent urinary accidents.
  • New cataract-like cloudiness, reduced energy, or repeated infections should be discussed promptly.

What to avoid

  • Do not change insulin, supplements, or food abruptly and do not give a human diabetes medicine.
  • Do not skip professional follow-up because appetite appears normal.

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.
