Canine and Feline Insulin Excess (Hyperinsulinism)
Insulin excess occurs when the pancreas releases too much insulin, driving blood sugar dangerously low. It causes weakness, wobbliness, and in severe cases seizures or collapse, and is usually managed by correcting the low sugar and treating the underlying cause.
Canine and Feline Insulin Deficiency (Diabetes Mellitus)
Diabetes mellitus develops when the pancreas cannot make enough insulin, so blood sugar stays high. It causes increased thirst and urination, weight loss, and poor appetite, and is managed with insulin therapy plus dietary and weight control.
Hypoparathyroidism in Dogs and Cats
Hypoparathyroidism is low parathyroid hormone from parathyroid injury that causes severe low blood calcium and neuromuscular hyperexcitability: muscle tremors, ataxia, and seizures. Correcting calcium with calcium and vitamin D is the mainstay of treatment.
Hyperparathyroidism in Dogs and Cats
Hyperparathyroidism is excess parathyroid hormone from a tumor or dietary imbalance that disrupts calcium-phosphorus balance, causing poor appetite, vomiting, weakness, and urinary stones or kidney failure. Treatment targets the cause and corrects calcium.
Hypothyroidism in Dogs and Cats
Hypothyroidism is reduced thyroid hormone from thyroiditis or tumor that slows metabolism, causing lethargy, weight gain, hair loss, and cold intolerance, sometimes with nerve signs. Lifelong thyroid-hormone replacement is the treatment.
Hyperthyroidism in Dogs and Cats
Hyperthyroidism is excess thyroid hormone from a thyroid tumor or hyperplasia that raises metabolism and nerve excitability. It causes weight loss with increased appetite, a fast or irregular heartbeat, and hyperactivity, and is managed with antithyroid drugs, radioactive iodine, or surgery.
Hypopituitarism in Dogs and Cats
Hypopituitarism results from tumors, inflammation, or trauma damaging the pituitary or hypothalamus, leading to failure of the target glands. Young animals become dwarfs, while adults show genital atrophy, obesity, and diabetes-insipidus-like signs, and hormone replacement is the main treatment.
Ulnar Nerve Paralysis in Dogs and Cats
Ulnar nerve paralysis follows direct trauma or prolonged ischemia from lying on one side under anesthesia, causing difficulty walking, bent joints, and a dragged limb. Timely nerve care improves the outcome.
Sciatic Nerve Injury in Dogs and Cats
Sciatic nerve injury usually follows a severe traumatic fracture and often involves the tibial and fibular branches, leaving multiple joints unable to flex or extend. Timely care helps avoid muscle wasting or lifelong lameness.
Tibial and Fibular Nerve Paralysis in Dogs and Cats
Tibial and fibular nerve paralysis impair normal hind-limb movement, causing an abnormal high-step or a knuckled, dragging paw, and eventually muscle wasting. Acupuncture and nutritional support aid recovery.
