Disorder - Diabetes MellitusOrgan Systems Involved
The hormone insulin is produced in the pancreas to break down sugar, thus regulating blood sugar levels. Due to a functional failure of the pancreas, blood sugar concentrations increase to levels that are too high.
In affected dogs the pancreas is unable to produce sufficient amounts of insulin, resulting in an increase in blood sugar. The surplus sugar is then excreted into the urine, causing larger volumes than normal to be produced. Excessive water consumption and increased urination (often inside the home) are symptoms of this, and as a result the dog may become significantly dehydrated. Diabetic animals also tend to have an increased appetite while showing signs of weight loss. This is due to the body's breakdown of fat stores as an alternative energy source. If the classic signs of diabetes mellitus have escaped detection, the dog is at risk of developing further symptoms such as vomiting, loss of appetite and weakness as blood sugar levels increase. Cataracts (cloudiness) in the eyes are also a common clinical sign. In general diabetes can be managed in the long term, with success in maintaining a stable condition often being dependent on the dedication of the owner. Affected animals will require constant administration of medication, and regular monitoring of blood sugar levels for life.
