What happens to urine output in acute glomerulonephritis?

In acute glomerulonephritis, urine output is typically decreased. This is because the damaged glomeruli are unable to filter waste products from the blood as effectively, leading to a buildup of fluid and waste products in the body. This can cause the urine to become concentrated and dark in color, and may also lead to the development of edema (swelling) in the face, hands, and feet.

The decrease in urine output can also lead to an increase in blood pressure, as the body is unable to eliminate excess fluid and waste products. This can further damage the glomeruli and worsen the condition.

In severe cases of acute glomerulonephritis, the urine output may decrease to the point of anuria, which is the complete absence of urine output. This is a medical emergency and requires immediate treatment.
