Introduction
In diabetes insipidus, the 24-hour urine volume generally ranges from 4 to 10 liters. Diabetes insipidus refers to a disorder of tubular reabsorption caused by either varying degrees of deficiency in arginine vasopressin or decreased renal tubular sensitivity to arginine vasopressin due to other reasons. Patients with diabetes insipidus experience excessive urination.
The 24-hour urine output in patients with diabetes insipidus typically ranges from 4 to 10 liters.
Diabetes insipidus refers to a disorder of renal tubular reabsorption function caused by varying degrees of deficiency in arginine vasopressin (AVP), or by reduced renal tubular sensitivity to AVP due to other factors. Patients with diabetes insipidus experience excessive urination, and their 24-hour urine volume can reach 4–10 liters. Without timely replenishment of fluids and electrolytes, symptoms such as dehydration, electrolyte imbalance, dry skin, reduced sweating, dry mouth, constipation, and even mental confusion or coma may occur.
Some cases of diabetes insipidus are caused by trauma or infections, while others result from tumors affecting the hypothalamic nerves or adjacent regions. These conditions impair antidiuretic hormone function, leading to defective water reabsorption in the renal tubules and causing diabetes insipidus. Treating the underlying disease is essential for symptom relief. For central diabetes insipidus caused by pituitary tumors, prompt medical evaluation is necessary, and treatment under a physician's guidance—such as surgery or gamma knife radiosurgery—may be required.
Patients should limit intake of high-fat and high-salt foods, maintain adequate fluid intake, and increase consumption of fresh vegetables.
