The harm of glomerulonephritis is multifaceted, and its damage to the human body is not only in terms of the kidneys, glomerulonephritis is one of a variety of renal diseases, as glomerulonephritis is relatively common, many patients do not take it for granted, not knowing that glomerulonephritis is also not to be underestimated in terms of the harm caused to the patient, and some of them lead to the terminal stage of renal disease — uremia, which seriously jeopardizes the patient’s life and his happy life, causing irreparable damage. -Uremia, which seriously jeopardizes the patient’s life and his happiness, causing irreparable losses, here we come together to understand what are the hazards of glomerulonephritis. Hazard a] proteinuria: due to a variety of inflammatory mediators and vasoactive substances, so that capillary permeability increases, protein filtration, causing proteinuria, seen in various types of glomerulonephritis. Hazard two] urinary abnormalities: glomerulonephritis will cause the patient’s urine volume most of the less, most of the less than 1,000 ml per day, a few can be oliguria, often accompanied by swelling; tubular function damage is more obvious, the urine volume increases, and accompanied by nocturia, edema is not obvious, and even the signs of dehydration. Hazard three] hematuria hematuria: due to glomerular capillary wall permeability increased significantly or capillary wall fracture caused. See capillary proliferative glomerulonephritis, crescentic glomerulonephritis, thylakoid proliferative glomerulonephritis and focal glomerulonephritis. Hazard four] central nervous system symptoms: headache, dizziness, loss of appetite, fatigue, insomnia, etc., which is related to hypertension, anemia, certain metabolic and endocrine dysfunction. Anemia: the decrease of erythropoietin secreted by the kidneys is related to the decrease of differentiation, maturation and release of red blood cells. [Hazard VI] Other: often due to hypertension, atherosclerosis, anemia and cardiac insufficiency, long-term protein loss in the urine, causing hypoproteinemia.
