Glomerulonephritis is a kidney condition that involves damage to the glomeruli. Glomeruli are the tiny structures within the kidney that filter blood.
The kidneys are bean-shaped organs located in the back just below the rib cage. Each kidney is about the size of a fist. The two kidneys filter blood, catch needed substances and return them to the circulation, and dispose of wastes in the urine. If the kidneys don’t filter properly, wastes build up in the blood.
There are two types of glomerulonephritis: Acute glomerulonephritis begins suddenly.Chronic glomerulonephritis develops gradually over several years.
In some cases, glomerulonephritis leads to kidney failure.

The symptoms of acute glomerulonephritis may include: Blood in urineFoamy appearance of urineLess frequent urinationSwelling in the morning, especially in the face, feet, hands, and abdomen

Images may be taken of your bodily structures. This can be done with: UltrasoundAbdominal CT scan
Treatment will depend on the cause of glomerulonephritis. The following steps may be taken to help kidney function or reduce further damage: Diuretics to reduce fluid retentionMedications to suppress the immune system such as steroidsACE inhibitors to control blood pressure and protein excretion Restrict salt and water intake.Restrict intake of potassium, phosphorous, and magnesium.Cut down on protein
in the diet.Maintain a healthy weight
through diet and exercise.Take calcium supplements.
If the kidneys are unable to remove sufficient waste from the blood,
may be required. Temporary dialysis may be sufficient for acute glomerulonephritis. If it leads to permanent kidney failure, chronic glomerulonephritis will require long-term dialysis or
