The first, diabetes insipidus, is a problem that develops in the pituitary gland of the brain. This gland produces a hormone called ADH which tells kidneys to save water. In the absence of this hormone, the kidneys do not save water and the patient develops increased urination, and increased thirst. The second diabetes, the one called mellitus is the usual diabetes we think about. It is also called sugar diabetes.
Pets can get sugar diabetes just like people.
The big problem with sugar diabetes is caused by a lack of control of sugar levels in the blood. When the sugar levels go too high, lots of problems occur. First, the kidneys who are suppose to save sugar, begin to spill sugar out in the urine. Kidneys are suppose to conserve water but the sugar in the urine causes the kidneys to lose water. This makes the patient urinate more and drink more.
