Difference Between Diabetes Mellitus And Diabetes Insipidus: Diabetes Mellitus is caused by either insufficient insulin or hyposecretion of insulin. Type 1 diabetes mellitus (formerly known as insulin-dependent diabetes mellitus) and type 2 diabetes mellitus (also known as non-insulin-dependent diabetes mellitus) are the two most common types.
Type 1 diabetes is caused by the loss of beta cells in the pancreas, which results in insufficient insulin production. Type 2 diabetes, on the other hand, is caused by insulin resistance, which occurs when cells do not respond effectively to insulin, resulting in elevated blood glucose levels. Diabetes insipidus is a distinct condition caused by a lack of vasopressin or antidiuretic hormone (ADH) released by the posterior pituitary gland. This disorder is distinguished by polyuria, characterized by the excretion of large volumes of diluted urine due to insufficient water reabsorption by kidney tubules. The table below comprehensively compares the key difference between diabetes mellitus and diabetes insipidus.NEET Biology Syllabus | NEET Biology Diagrams |

Diabetes mellitus and diabetes insipidus share a common prefix, but they are distinct illnesses with different causes, symptoms, and treatments. Diabetes mellitus, commonly known as diabetes, is caused by the pancreas's inability to produce enough insulin. Insulin is a hormone that helps glucose, or sugar, enter cells for energy. Without enough insulin, blood sugar levels can become too high. Diabetes insipidus is a rare disorder not caused by the pancreas or blood sugar regulation. It occurs when the kidneys produce too much urine. The kidneys normally filter about a quart or two of urine daily from the bloodstream. However, in people with diabetes insipidus, urine output can range from 3 to 20 quarts, primarily consisting of water. This excessive loss of fluids leads to intense thirst. The following table concisely overviews the key differences between diabetes mellitus and diabetes insipidus.
Diabetes Mellitus and Diabetes Insipidus share a few overlapping symptoms but are completely distinct. The only similarity between the two diseases is the initial word of their names. Diabetes Mellitus and Diabetes Insipidus cause different health problems and require distinct treatment approaches. The table below summarizes the key difference between Diabetes Mellitus and Diabetes Insipidus.
Difference Between Diabetes Mellitus And Diabetes Insipidus | ||
---|---|---|
Characteristic | Diabetes Mellitus | Diabetes Insipidus |
Symptoms | Increased blood sugar level, glucose in urine, excessive urine, thirst, and appetite | Large quantity of diluted, glucose-free urine, excessive thirst, dehydration |
Cause | Insulin deficiency | Failure of Antidiuretic hormone or vasopressin secretion |
Glycosuria | Sugar excreted in urine | No sugar excreted in urine |
Blood Sugar Level | Elevated blood glucose level | Normal blood glucose level |
Increase in Urine Volume | Volume increase due to osmotic effect of glucose | Volume increase due to decreased water absorption in renal tubules |
Urine Concentration | Normal urine concentration | Very dilute urine concentration |
Cholesterol | Urine concentration of cholesterol rises | Urine concentration of cholesterol remains normal |
Hunger | Excessive hunger | Normal hunger |
Ketone Bodies | Present in blood and urine | Absent in blood and urine |
Volume of Urine | Excessive volume of urine | Enormous volume of urine |
