What Causes Kidney Failure?
Almost all the kidney diseases attack nephrons and make them lose their ability to filter. Damage to nephrons can happen quickly, often as a result of injury or poisoning. But most kidney diseases destroy nephrons slowly without causing obvious symptoms. Only when they pass a few years or even decades will begin to demonstrate the harm. Most kidney diseases attack both kidneys simultaneously, devastating healthy kidney function.
The two causes of kidney disease are the most common diabetes and high blood pressure. If your family has a history of kidney problems, you may run the risk of kidney disease.
Diabetic Nephropathy
Diabetes is a disease that prevents the body to use glucose (sugar) in an appropriate manner. If glucose stays in the blood instead of down, can act as a poison. The damage caused by the nefronas unused glucose in the blood is called diabetic nephropathy. Controlled by maintaining the levels of blood glucose (blood sugar), you can delay or prevent diabetic nephropathy.
High Blood Pressure
High blood pressure can damage the small blood vessels in the kidneys. The damaged vessels can not filter waste from the blood properly.
It is possible that the doctor prescribes medicines to control blood pressure. It has been discovered that some medications for high blood pressure protect the kidneys even more than other drugs that lower blood pressure to similar levels. These drugs are known as inhibitors of angiotensin converting enzyme, ACE by its initials in Spanish, and angiotensin receptor blocker, ARB by its acronym in English. The National Heart, Lung, and Blood Institute, NHLBI by their initials, which is called in Spanish National Heart, Lung and Blood Institute recommends that people with diabetes or reduced kidney function maintain their blood pressure below 130/80 mm Hg. NHLBI is part of the National Institutes of Health, which are called in Spanish National Institutes of Health.
Glomerular Diseases
In this category are grouped different types of renal diseases, including autoimmune diseases, diseases related to infections and diseases sclerotic. As its name indicates, glomerular diseases attack the tiny blood vessels (glomeruli) that are within the kidney. The most common primary glomerular diseases include membranous nephropathy, IgA nephropathy and focal segmental glomeruloesclerosis. Protein, blood or both substances in the urine are often the first signs of these diseases. They can slowly destroy kidney function. It is important to control blood pressure if you have kidney disease. Depending on the specific disease, treatments for diseases Glomerular are immunosuppressive drugs or steroids to reduce inflammation and proteinuria.
Hereditary Diseases or Congenital Kidney
Some kidney diseases are the result of hereditary factors. For example, polycystic kidney disease (PKD), is a genetic disorder that causes the formation of multiple cysts in the kidneys. The cysts can slowly replace much of the mass of the kidneys, reducing kidney function and leads to kidney failure.
Some kidney problems may occur when a fetus is still in the womb of the mother. Examples include autosomal recessive polycystic kidney, a rare form of polycystic kidney and other problems that hinder development of the normal training nefronas. The signs of kidney disease in children vary. A child may have an abnormally slow growth, which often vomit or have back pain or side. Some kidney diseases may be “silent” for months or even years, or no symptoms in its early stages.
If your child has a kidney disease, the child’s doctor should be detected during a regular medical checkup. Take your child to the doctor regularly. The first sign of a kidney problem may be high blood pressure, a small number of red blood cells (anemia), or blood or protein in the urine of children. If the doctor finds any of these problems, may have to do other tests, even more blood and urine tests or radiology studies. In some cases, may require that the doctor have a biopsy, which is to take a tiny piece of kidney tissue to examine under a microscope.
It is possible that some hereditary kidney disease not be detected until adulthood. The most common form of polycystic kidney was once called “adult polycystic kidney,” because the symptoms of high blood pressure and kidney failure can not occur until patients are between 20 to 30 years. But with advances in imaging technology, doctors have found cysts in children and adolescents before they present symptoms.
Other Causes of Kidney Disease
The Poisons and trauma, for example, a direct hit hard in the kidneys and can cause kidney disease.
Some OTC medicines can be poisonous to the kidneys if taken regularly for a long time. It has been discovered that the products that combine aspirin, acetaminophen and other drugs such as ibuprofen, are most dangerous to the kidneys. If you take regular medication for pain relief, see your doctor to make sure not to risk the kidneys, and ensure proper kidney function.
