There are, lets say, 2 classes of Diabetes
1) Diabetes Mellitus Type 1 & 2: problem with Insulin making/secreting.
2) Diabetes Insipidus: a) Nephrogenic Diabetes Insipidus: In this diabetes, kidneys are unable to conserve water. Leading to polyuria/polydipsia.
b) Neurogenic Diabetes Insipidus: The hormone that is used and act on kidneys to cause less urine output, basically not working. Its a problem in the pituitary gland directly instead of the Kidney.
So, yea, If there is a kidney problem then definitely expect to have Diabetes Insipidus [Nephrogenic] but not Mellitus. Sugar level might be normal but the function of conserving water will be lost.
Good post.
Diabetes mellitus has two types. Type 1 and 2.
Diabetes Insipidus should not be mistaken as same as Diabetes Mellitus type 2. by someone reading this.
In fact diabetes insipidus is whole different disease and nothing to do with diabetes mellitus.
The word "diabetes" is borrowed from the Greek word meaning "a siphon."
The 2nd-century A.D. Greek physician, Aretus the Cappadocian, named the condition "diabetes." He explained that patients with it had polyuria and "passed water like a siphon."
Since both very different diseases diabetes mellitus and diabetes insipidus cause someone to urinate a lot, they both are called "diabetes".
For diabetes mellitus new cutoff for definition is 110mg/dl whole blood glucose and 126 mg/dl plasma glucose on fasting at least 8 hours. Not even smoking.
