Nephrogenic diabetes insipidus occurs when the kidneys do not respond normally to vasopressin and continue to remove too much fluid from a person's bloodstream. Nephrogenic diabetes insipidus can result from inherited gene changes, or mutations, that prevent the kidneys from responding to vasopressin. Other causes of nephrogenic diabetes insipidus include
A person's body regulates fluid by balancing liquid intake and removing extra fluid. Thirst usually controls a person’s rate of liquid intake, while urination removes most fluid, although people also lose fluid through sweating, breathing, or diarrhea. The hormone vasopressin, also called antidiuretic hormone, controls the fluid removal rate through urination. The hypothalamus, a small gland located at the base of the brain, produces vasopressin. The nearby pituitary gland stores the vasopressin and releases it into the bloodstream when the body has a low fluid level. Vasopressin signals the kidneys to absorb less fluid from the bloodstream, resulting in less urine. When the body has extra fluid, the pituitary gland releases smaller amounts of vasopressin, and sometimes none, so the kidneys remove more fluid from the bloodstream and produce more urine.
People who are obese -- more than 20% over their ideal body weight for their height -- are at particularly high risk of developing type 2 diabetes and its related medical problems. Obese people have insulin resistance. With insulin resistance, the pancreas has to work overly hard to produce more insulin. But even then, there is not enough insulin to keep sugars normal.
Metformin is generally recommended as a first line treatment for type 2 diabetes, as there is good evidence that it decreases mortality.[7] It works by decreasing the liver's production of glucose.[90] Several other groups of drugs, mostly given by mouth, may also decrease blood sugar in type II DM. These include agents that increase insulin release, agents that decrease absorption of sugar from the intestines, agents that make the body more sensitive to insulin, and agents that increase the excretion of glucose in the urine.[90] When insulin is used in type 2 diabetes, a long-acting formulation is usually added initially, while continuing oral medications.[7] Doses of insulin are then increased to effect.[7][91]
Insulin is a hormone produced by cells in the pancreas called beta cells. Insulin helps the body use blood glucose (a type of sugar) for energy. People with type 2 diabetes do not make enough insulin and/or their bodies do not respond well to it, leading to elevated blood sugar levels. Oral diabetes medications bring blood sugar levels into the normal range through a variety of ways.

Fatigue and muscle weakness occur because the glucose needed for energy simply is not metabolized properly. Weight loss in type 1 diabetes patients occurs partly because of the loss of body fluid and partly because in the absence of sufficient insulin the body begins to metabolize its own proteins and stored fat. The oxidation of fats is incomplete, however, and the fatty acids are converted into ketone bodies. When the kidney is no longer able to handle the excess ketones the patient develops ketosis. The overwhelming presence of the strong organic acids in the blood lowers the pH and leads to severe and potentially fatal ketoacidosis.

High blood sugar (hyperglycemia). Lots of things can cause your blood sugar to rise, including eating too much, being sick or not taking enough glucose-lowering medication. Watch for signs and symptoms of high blood sugar — frequent urination, increased thirst, dry mouth, blurred vision, fatigue and nausea — and check your blood sugar if necessary.
Central diabetes insipidus. A synthetic, or man-made, hormone called desmopressin treats central diabetes insipidus. The medication comes as an injection, a nasal spray, or a pill. The medication works by replacing the vasopressin that a patient’s body normally produces. This treatment helps a patient manage symptoms of central diabetes insipidus; however, it does not cure the disease.
The word "diabetes" (/ˌdaɪ.əˈbiːtiːz/ or /ˌdaɪ.əˈbiːtɪs/) comes from Latin diabētēs, which in turn comes from Ancient Greek διαβήτης (diabētēs) which literally means "a passer through; a siphon".[17] Ancient Greek physician Aretaeus of Cappadocia (fl. in the first century CE) used that word, with the intended meaning "excessive discharge of urine", as the name for the disease.[18][19] Ultimately, the word comes from Greek διαβαίνειν (diabainein), meaning "to pass through",[17] which is composed of δια- (dia-), meaning "through" and βαίνειν (bainein), meaning "to go".[18] The word "diabetes" is first recorded in English, in the form "diabete", in a medical text written around 1425.
People with diabetes can benefit from education about the disease and treatment, good nutrition to achieve a normal body weight, and exercise, with the goal of keeping both short-term and long-term blood glucose levels within acceptable bounds. In addition, given the associated higher risks of cardiovascular disease, lifestyle modifications are recommended to control blood pressure.[83][84]
The three primary types of diabetic medication include oral diabetes medication, insulin, and other types of injectable diabetes medicine. Within these broad groups, diabetic medication can be classified more specifically as belonging to certain classes. The following article provides a list of diabetic medication broken down by type and class of medicine.

Diabetes insipidus and diabetes mellitus—which includes both type 1 and type 2 diabetes—are unrelated, although both conditions cause frequent urination and constant thirst. Diabetes mellitus causes high blood glucose, or blood sugar, resulting from the body's inability to use blood glucose for energy. People with diabetes insipidus have normal blood glucose levels; however, their kidneys cannot balance fluid in the body.

So far, none of the hypotheses accounting for virus-induced beta cell autoimmunity has been supported by stringent evidence in humans, and the involvement of several mechanisms rather than just one is also plausible.

Your urinary system — which includes the kidneys, ureters, bladder and urethra — is responsible for removing waste from your body through urine. Your kidneys, located toward the back in your upper abdomen, produce urine by filtering waste and fluid from your blood. That urine then travels through your ureters to your bladder, where the urine is stored until you can eliminate it at an appropriate time.

Diabetes occurs throughout the world but is more common (especially type 2) in more developed countries. The greatest increase in rates has however been seen in low- and middle-income countries,[104] where more than 80% of diabetic deaths occur.[108] The fastest prevalence increase is expected to occur in Asia and Africa, where most people with diabetes will probably live in 2030.[109] The increase in rates in developing countries follows the trend of urbanization and lifestyle changes, including increasingly sedentary lifestyles, less physically demanding work and the global nutrition transition, marked by increased intake of foods that are high energy-dense but nutrient-poor (often high in sugar and saturated fats, sometimes referred to as the "Western-style" diet).[104][109] The global number of diabetes cases might increase by 48% between 2017 and 2045.[9]
