Chronic Conditions
40 Conditions in this category.
Cushing's Syndrome
Cushing's Syndrome, or hyperadrenocorticism, is a chronic endocrine condition resulting from the excessive production of cortisol by the adrenal glands.
Addison's Disease
Addison's Disease, or hypoadrenocorticism, is a chronic endocrine disorder in dogs caused by an insufficient production of glucocorticoids and mineralocorticoids by the adrenal glands.

Chronic Kidney Disease is a progressive, irreversible decline in renal function characterized by the kidneys' inability to effectively filter waste products from the bloodstream and maintain electrolyte balance.
Inflammatory Bowel Disease
Inflammatory Bowel Disease (IBD) is a chronic gastrointestinal disorder characterized by the persistent infiltration of inflammatory cells into the mucosal walls of the stomach, small intestine, or large intestine.
Hyperthyroidism
Feline hyperthyroidism is a common endocrine disorder caused by the excessive production of thyroid hormones due to a functional tumor of the thyroid gland.
Chronic Kidney Disease
Chronic Kidney Disease is a progressive, irreversible loss of renal function characterized by the kidneys' inability to adequately filter toxins or regulate fluid and electrolyte balance.
Hypothyroidism
Hypothyroidism is a common endocrine disorder in dogs resulting from the insufficient production of thyroid hormones, which regulate essential metabolic processes.
Feline Lower Urinary Tract Disease (FLUTD)
Feline Lower Urinary Tract Disease (FLUTD) is a complex collection of conditions affecting the bladder and urethra of cats, characterized by frequent, painful, or difficult urination.
Diabetes Mellitus
Diabetes Mellitus is a chronic endocrine disorder in cats and dogs characterized by the body's inability to regulate blood glucose levels due to insulin deficiency or resistance.
Avian Goiter
Avian goiter is a chronic enlargement of the thyroid gland in birds, typically resulting from dietary iodine deficiency, which leads to airway compression and respiratory distress.
Equine Osteoarthritis
Equine osteoarthritis is a chronic, progressive degenerative joint disease characterized by the breakdown of cartilage, inflammation, and bone remodeling, leading to pain and lameness in horses.
Cognitive Dysfunction Syndrome
Cognitive Dysfunction Syndrome (CDS) in cats is a progressive neurodegenerative condition impacting older cats, akin to Alzheimer's disease in humans, leading to behavioral changes and a decline in cognitive function.
Cholangiohepatitis
Cholangiohepatitis is a chronic inflammatory liver disease in cats, often part of a triad involving the pancreas and small intestine, leading to progressive liver damage.
Fatty Liver Syndrome
Feline Hepatic Lipidosis, commonly known as fatty liver syndrome, is a life-threatening metabolic condition occurring when a cat stops eating, leading to a massive accumulation of triglycerides in liver cells.
Acromegaly
Acromegaly, or hypersomatotropism, is a chronic endocrine condition in cats caused by excessive secretion of growth hormone, typically from a pituitary tumor.
Hyperaldosteronism
Feline hyperaldosteronism, or Conn’s syndrome, is an endocrine disorder caused by excessive production of the hormone aldosterone by the adrenal glands, leading to severe potassium depletion and hypertension.
Hypocalcemia
Hypocalcemia is a critical medical condition characterized by abnormally low levels of calcium in the blood, impacting various bodily functions and requiring prompt veterinary attention.
Portal Hypertension
Portal hypertension is a pathological increase in blood pressure within the portal venous system, typically secondary to structural liver disease, vascular anomalies, or obstruction of venous outflow.
Hypercalcemia
Hypercalcemia is a condition characterized by abnormally elevated levels of calcium in the bloodstream, which can lead to systemic organ damage if left untreated.
Hypoadrenocorticism
Hypoadrenocorticism, commonly known as Addison's disease, is a life-threatening endocrine disorder in dogs caused by the insufficient production of glucocorticoid and mineralocorticoid hormones by the adrenal glands.
Glomerulonephritis
Glomerulonephritis is an immune-mediated inflammation of the kidney's filtering units, the glomeruli, leading to protein leakage and potential progressive renal dysfunction.
Exocrine Pancreatic Insufficiency
Exocrine Pancreatic Insufficiency (EPI) is a chronic digestive condition where the pancreas fails to produce sufficient enzymes, preventing the body from properly breaking down and absorbing nutrients from food.
Renal Amyloidosis
Renal amyloidosis is a progressive, irreversible condition characterized by the extracellular deposition of insoluble fibrillar proteins within the kidney, leading to nephrotic syndrome and chronic renal failure.
Hyperadrenocorticism
Hyperadrenocorticism, commonly known as Cushing's disease, is a chronic endocrine condition characterized by the overproduction of cortisol by the adrenal glands.
Pheochromocytoma
Pheochromocytoma is a rare tumor of the adrenal gland in dogs that produces excess adrenaline, leading to a variety of serious health issues.
Fanconi Syndrome
Fanconi Syndrome is a chronic, often progressive disorder of the canine proximal renal tubules that leads to the excessive loss of essential electrolytes, glucose, and amino acids in the urine.
Hepatic Encephalopathy
Hepatic encephalopathy is a complex neurological syndrome resulting from severe liver dysfunction or portosystemic shunting, which causes toxic metabolites to reach the brain.
Diabetes Insipidus
Diabetes insipidus is a rare hormonal disorder characterized by the body's inability to concentrate urine, leading to extreme thirst and excessive urination.
Gallbladder Mucocele
Gallbladder mucocele is a life-threatening condition in dogs characterized by the accumulation of excessive, thick, inspissated mucus within the gallbladder, leading to bile duct obstruction or rupture.
Canine Cognitive Dysfunction
Canine Cognitive Dysfunction (CCD) is a progressive neurodegenerative condition in senior dogs similar to Alzheimer's disease in humans, characterized by behavioral and cognitive decline.
Fibrosing Liver Disease
Fibrosing liver disease in dogs is a chronic, progressive condition characterized by the excessive accumulation of fibrous connective tissue within the liver parenchyma, leading to impaired hepatic function and potential organ failure.
Chronic Pancreatitis
Chronic pancreatitis is a persistent, progressive inflammatory condition of the pancreas that leads to irreversible structural damage and loss of endocrine and exocrine function.
Chronic Hepatitis
Chronic hepatitis in dogs is a progressive inflammatory liver disease characterized by the long-term destruction of hepatocytes, which can eventually lead to hepatic fibrosis and irreversible cirrhosis.
Pyelonephritis
Pyelonephritis is a bacterial infection of the kidney and renal pelvis, often developing from a urinary tract infection that ascends from the bladder.
Immune-Mediated Hemolytic Anemia
Immune-Mediated Hemolytic Anemia (IMHA) is a chronic condition in dogs where the immune system mistakenly attacks and destroys red blood cells.
Lymphocytic Cholangitis
Lymphocytic Cholangitis is a progressive, immune-mediated inflammatory liver condition in cats characterized by the infiltration of lymphocytes into the bile ducts.
Equine Cushing’s Disease (PPID)
Pituitary Pars Intermedia Dysfunction (PPID), commonly known as Equine Cushing’s Disease, is a progressive neurodegenerative endocrine disorder caused by the loss of dopaminergic inhibition of the pituitary gland.
Equine Recurrent Airway Obstruction (Heaves)
Recurrent Airway Obstruction (RAO), often called heaves, is a chronic, non-infectious inflammatory airway disease in horses triggered by inhaled allergens that leads to reversible bronchoconstriction and excessive mucus production.
Equine Gastric Ulcer Syndrome
Equine Gastric Ulcer Syndrome (EGUS) is a common condition characterized by the development of erosions or ulcers in the lining of a horse's stomach, often leading to discomfort, poor performance, and behavioral changes.
Equine Metabolic Syndrome
Equine Metabolic Syndrome is a complex endocrine disorder characterized by obesity, insulin resistance, and a high risk of laminitis in horses and ponies.
