3. Kidney disease
Blood in the urine could be a sign of kidney disease, which could be a cause for concern. With kidney disease, glomerulonephritis can occur, which causes the filtration system in the kidneys to become inflamed, which is the cause for the blood found in the urine. Kidney disease could be diabetes or other systematic diseases.
It could also be associated with a strep infection, an immune system deficiency, or a disease of the blood vessels. Kidney disease can be a grave condition and requires immediate medical attention. With prompt treatment, kidney disease can be eased.
