Understanding Polyphagia: Why is My Pet Always Hungry?

As a pet owner in Hong Kong, noticing that your dog or cat has a sudden, insatiable hunger can be confusing. While we often joke about our pets being “food motivated,” a drastic change in appetite—medically known as Polyphagia—is often a symptom of a physiological condition rather than a behavioral quirk. When searching for “43. pet increased appetite vet HK,” you are likely looking for answers regarding metabolic or digestive disorders.

At LAMCVET (Hong Kong Lai O Animal Medical Center), located conveniently in Yau Ma Tei, we see many cases where increased appetite is the first warning sign of conditions such as Diabetes, Hyperthyroidism, or Cushing’s Disease. Distinguishing between a healthy appetite and a pathological one is crucial for your pet’s longevity.

Common Medical Causes for Increased Appetite

Diabetes Mellitus

Diabetes is one of the most common reasons for increased appetite in both dogs and cats. When a pet lacks insulin or cannot use it effectively, their body’s cells cannot absorb glucose (sugar) from the blood. Consequently, the cells are “starving” for energy, which triggers the brain to demand more food. Despite eating voraciously, these pets often lose weight and drink excessive amounts of water.

Hyperthyroidism (Common in Cats)

If you have an older cat that is eating significantly more but losing muscle mass and acting hyperactive, Hyperthyroidism is a prime suspect. This condition involves an overproduction of thyroid hormones, which sends the metabolism into overdrive. Our clinic in Kowloon is fully equipped to diagnose this through blood panels and treat it effectively.

Cushing’s Disease (Hyperadrenocorticism)

More common in dogs, Cushing’s Disease results from the overproduction of cortisol. One of the classic symptoms is a ravenous appetite. Owners often report their dogs stealing food or rummaging through garbage. Other signs include a pot-bellied appearance, hair loss, and increased panting. Diagnosing Cushing’s often requires specific blood stimulation tests and advanced imaging.

Advanced Diagnostics at LAMCVET Yau Ma Tei

Identifying the cause of increased appetite requires more than a physical exam. As the largest veterinary clinic in Yau Ma Tei, LAMCVET is equipped with state-of-the-art technology to provide accurate diagnoses under one roof.

• Comprehensive Blood Panels: To check for diabetes, liver function, kidney health, and thyroid hormone levels.
• Digital X-Ray & Ultrasound: To examine the abdomen for tumors or organ enlargement.
• CT & MRI Scanners: We are one of the few clinics in Kowloon with in-house CT and MRI capabilities. This is vital for detecting pituitary tumors (which cause Cushing’s) or other internal masses that standard X-rays might miss.
• Urinalysis: Essential for diagnosing diabetes and assessing kidney function.
