Step-by-step explanation:
The medical term for reduced urination is oliguria. This condition is characterized by an abnormally small amount of urine, which can be less than 400-500 mL/day and may occur in various situations, including conditions like fever, shock, vomiting, and diarrhoea. Oliguria is often due to decreased kidney function or acute conditions that affect fluid and electrolyte balance in the body. Other urinary conditions include hematuria, which is the presence of red blood cells in the urine, often caused by an infection or injury; polyuria, where there is an abnormally large amount of urine output, commonly associated with diabetes; and dysuria, which involves painful or uncomfortable urination that can result from urinary tract infections.
