What is azotemia?
Azotemia concerns the unusually high amounts of nitrogen waste products in the bloodstream. Normally the kidneys filter blood and secrete waste in the form of urine. In the case of azotemia, the kidneys are not able to sufficiently remove urea, creatinine and other compounds containing nitrogen from the blood. An individual with a condition may have fatigue, confusion, high blood pressure and possible renal failure without treatment. Emergency care is often required to identify and remedy the basic cause to prevent serious health complications. Prerestal azotemia refers to a complication that reduces blood flow to the kidneys such as atherosclerosis. Intrarenal azotemia is essentially kidney failure; The problem is the kidneys themselves. Postrenal azotemia is the result of an obstacle to the urine flow after the waste leaves the kidneys. All three types can lead a dangerous increase in urea nitrogen (Bun) and other compounds that are usually excluded by the urine.
A person with one of three types of azotemia may suffer from rapid heart rate and increased blood pressure. He or she could become confused, tired and lightened and experienced reduced urine production. In addition, the skin can pale and the joints can become inflamed and swollen. Some people experience significant pain and tenderness in the abdomen and lower back. The beginning of the condition is often acute, which means that symptoms suddenly appear, although some cases gradually deteriorate within a few weeks or months.
An individual who believes that he has symptoms of azotemia should see a doctor or go to the emergency room as soon as possible. The physician may perform a thorough physical examination, ask the patient for symptoms and rails of blood and urine for laboratory analysis. Laboratory specialists can confirm the diagnosis by identifying high levels of Bun in the blood and low nitrogen levels in the urine. Other diagnostic imaging tests such as sonograms can help doctors to determine the basic cause of kidney problemsus.
patients are often placed in the hospital and administer intravenous fluids to reduce the risk of dehydration. If the problem is found as intrarenal, the dialysis machine can be used to temporarily take over the blood filtration process, while kidney problems are evaluated. Many patients with re -henal and post -seal problems are able to recover by taking medication to control blood pressure, open narrow blood vessels and decrease inflammation. Surgery may be necessary if the kidneys are completely closed or blocking is not resolved.
