One of the most common signs of glomerulonephritis is blood in the urine, which may appear pink, red, or cola-colored due to damaged glomeruli allowing red blood cells to pass through.

Excess protein in the urine causes it to appear foamy or bubbly. This happens when inflamed glomeruli cannot properly filter protein, leading to its leakage into the urine.

Fluid retention due to protein loss causes swelling in the face, around the eyes, in the hands, feet, and abdomen. This is a classic symptom of glomerulonephritis.

Damaged glomeruli cannot regulate blood pressure effectively, leading to hypertension. High blood pressure can further worsen kidney damage, creating a vicious cycle.

As kidney function declines and waste products accumulate in the blood, patients may experience nausea, vomiting, and a general feeling of being unwell.

Reduced kidney function can lead to metabolic changes and toxin buildup, resulting in decreased appetite, unintentional weight loss, and nutritional deficiencies.

Anemia often accompanies glomerulonephritis due to reduced production of erythropoietin, leading to persistent tiredness, weakness, and difficulty concentrating.

In acute glomerulonephritis, patients may notice a significant decrease in the amount of urine produced, sometimes accompanied by dark-colored urine.

Some patients experience dull, aching pain in the back or sides (flank area) where the kidneys are located, due to inflammation and swelling of kidney tissues.

Waste buildup in the bloodstream due to impaired kidney function can cause persistent itching and skin irritation, which is common in advanced kidney conditions including glomerulonephritis.
