Dogs typically develop type I diabetes. The clinical signs include polyuria and polydipsia, polyphagia, weight change, hepatomegaly, cataracts, and … Diabetes mellitus is frequently diagnosed in dogs five years of age or older. The amyloid or IAPP (or both) lead to physical disruption of the β cell and insulin resistance, resulting in diabetes. Glucose is a vital substance that provides much of the energy needed by cells, but it must first be absorbed by the cells. Diabetes mellitus can be a threat to the health of the dog since it may cause urinary tract infections. A redistribution of fat into the abdominal cavity may occur with Cushing's disease. About Diabetes Mellitus. In dogs, multiple underlying pathological processes result in diabetes and the most common are type 1, other specific types of diabetes, and diestrual. The selective degeneration and necrosis of β cells is accompanied by infiltration of the islets by lymphocytes and macrophages. Cataracts develop frequently in dogs (not cats) with poorly controlled diabetes mellitus. Normally, the cells of the body use insulin to take in the glucose and use it for energy. Determining the amount of these factors in the blood can provide evidence of dysfunction or disease in certain organs or metabolic pathways indicative of certain diseases. These include dehydration, hypovolemia, elevated anion gap, metabolic acidosis, electrolyte disturbances, azotemia, elevated liver enzymes, hyperlactatemia, and clinical signs of vomiting and anorexia. There is a congenital form that occurs in puppies called Type I or ju venile diabetes, but this is rare in dogs. A case-control study of spontaneous diabetes mellitus in dogs was undertaken, using 2 veterinary data bases. Usually increased production of dilute urine results in a compensatory increase in water consumption, but occasionally the condition is one of increased water intake resulting in the production of large volumes of dilute urine. Certain conditions predispose a dog or cat to developing diabetes. Type I diabetes mellitus (sometimes also called insulin-dependent diabetes mellitus) results from total or near-complete destruction of the insulin-producing beta cells. The link you have selected will take you to a third-party website. Without an adequate amount of insulin to 'open the door,' glucose is unable to get into the cells and accumulates in the blood, causing hyperglycemia. Most dogs with controlled diabetes live a good quality of life with few symptoms of disease. In cats, hepatic lipidosis may occur in conjunction with diabetes mellitus. Complete expression of the complex metabolic disturbances in diabetes mellitus appears to be the result of a bihormonal abnormality. Later in the course of disease, a thin, fibrous band of tissue near the duodenum and stomach may be all that remains of the pancreas. diagnosed with the more common type of diabetes, diabetes mellitus. Diabetic animals have decreased resistance to bacterial and fungal infections and often develop chronic or recurrent infections such as cystitis, prostatitis, bronchopneumonia, and dermatitis. In cases of stress-induced hyperglycemia, the fructosamine concentrations are normal. In simple terms, diabetes mellitus is caused by the failure of the pancreas to regulate blood sugar. In dogs, diabetes mellitus is usually insulin dependent diabetes mellitus (also called Type 1 diabetes). These clinical signs are non-specific and can be caused by many different diseases or conditions. Cats with diabetes have a greater percentage of their islets affected, with larger amounts of amyloid than age-matched cats without diabetes. See pet owner information about diabetes mellitus in dogs, cats, horses, or birds. Diabetes insipidus and diabetes mellitus are two different types of diabetes in dogs, and both can be serious if left untreated. Diabetes Mellitus in dogs and cats results from a decrease in insulin secretion from the beta cells of the pancreas and/or a decrease in insulin action. The Veterinary Manual was first published in 1955 as a service to the community. In newly diagnosed cats, insulin glargine is the insulin of choice. This is also known as Ty pe II or adult-onset diabetes. Type I diabetes mellitus (sometimes also called insulin-dependent diabetes mellitus) results from total or near-complete destruction of the insulin-producing beta cells. Type III diabetes results from insulin resistance caused by other hormones and can be due to pregnancy or hormone-secreting tumors. Animals that are overweight or those with inflammation of the pancreas are predisposed to developing diabetes. Therapy includes correcting dehydration by administration of IV fluids, such as 0.9% NaCl or lactated Ringer’s solution; reducing hyperglycemia and ketosis by administration of crystalline zinc (regular) insulin; maintaining serum electrolyte levels, especially potassium, through supplemental administration of appropriate electrolyte solutions; and identifying and treating underlying and complicating diseases, such as acute pancreatitis or infections. It may take a month or more to achieve good insulin regulation. Individual liver cells are greatly enlarged by the accumulation of multiple droplets of neutral lipid. Insulin regulates the level of glucose (sugar) in the bloodstream and controls the delivery of glucose to the tissues of the body. Clinical Findings. IDDM probably depends upon the combination of genetic susceptibility, environmental (pollutants, infection-pancreatitis), followed by persistent immune destruction of the beta islet cells, resulting in severe insulin deficiency, … Treatment involves rehydration and the use of short- and long-acting insulins to reduce ketone production and establish euglycemia. To conserve glucose within the body, the kidneys do not filter glucose out of the blood stream into the urine until an excessive level is reached. Stress, obesity, and administration of corticosteroids or progestogens may increase the severity of clinical signs. Basal insulins are the preferred treatment in cats, with lente the insulin of choice in dogs. In all cases, a search should be made for drugs or diseases that predispose to diabetes. Diabetes mellitus is a chronic disorder of carbohydrate metabolism due to relative or absolute insulin deficiency. This means that you, as the dog's owner, must make both a financial and personal commitment to treat your dog. As the name implies, dogs with this type of diabetes require insulin injections to stabilize blood sugar. Type II diabetes may occur in older obese dogs. Just like people, our pups can become diabetic too. Recent studies advocate the use of glargine rather than regular insulin in the management of ketoacidotic diabetes mellitus, with encouraging results. Although the symptoms of diabetes mellitus such as frequent urination, thirstiness, greater appetites and inactiveness are easily visible, frequent checking of the dog for the disease is required. From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world. Once the animal is on maintenance therapy and its condition is stable, therapy should be reassessed every 4–6 months. Ketoacidosis is a serious complication of diabetes mellitus and should be regarded as a medical emergency. A diagnosis of diabetes mellitus is based on persistent fasting hyperglycemia and glycosuria. Obese male cats seem to be more commonly affected than female cats, and breeds such as Burmese, Russian Blue, Norwegian Forest Cat, Abyssinian, and Tonkinese appear predisposed. With twice daily injections, two meals of equal calories are given at the time of insulin administration. Although the same sorbitol pathway seems to be present in cats, the development of cataracts is rare. Cotton RB, Cornelius LM, Theran P. PMID: 5106546 [PubMed - indexed for MEDLINE] MeSH Terms. Cats with diabetes mellitus usually have specific degenerative lesions localized selectively in the islets of Langerhans, whereas the remainder of the pancreas appears to be normal. Short-term success is seen in 50% of treated cats, with longterm success rates (>1 yr) of ~15%. One example of an ’immediate crisis’ is a dog that is so sick he has stopped eating and drinking for several days. The normal fasting value for blood glucose in dogs and cats is 75–120 mg/dL. Diabetes is a common endocrine disorder seen in clinical practice. Other extrapancreatic lesions associated with diabetes mellitus in people, such as nephropathy, retinopathy, and micro- and macrovascular angiopathy, are rare in dogs and cats. Insulin resistance and secondary diabetes mellitus are also seen in many dogs with spontaneous hyperadrenocorticism and after chronic administration of glucocorticoids or progestins. Diabetes mellitus is a chronic condition that affects your dog’s ability to use the carbohydrates in food for energy. When insulin therapy has been instituted, the blood glucose should be checked frequently until an adequate maintenance dose has been determined.
