Anuria is a condition that occurs when the body isn’t producing enough urine, but why would this happen? Watch this lesson to learn about anuria and its causes, symptoms, and possible treatment options.
What Is Anuria?
Urine. Everybody’s body produces it, but how many of us know where it actually comes from or what it’s for? Turns out, the kidneys are responsible for filtering waste material out of the blood so that it can be removed from the body through urine.
For the most part, this process runs smoothly. However, when this system is disrupted, the body doesn’t produce enough urine, causing these waste materials to build up in the body.Anuria is the condition where the body produces too little urine, and if left untreated, it can lead to high blood pressure, heart failure, anemia, platelet disorders, gastrointestinal problems, and even death. Typically, anuria is characterized by a daily urine output that’s less than 100 milliliters, and it can be a symptom of kidney failure, which is lethal.
Causes of Anuria
The different types of anuria are categorized based on where the problem is located in the body, which is directly tied to what’s causing it. Prerenal anuria occurs when the structural problem is located before the kidneys, such as if there is limited blood flow supplying the kidneys. This can occur due to heart failure, certain diseases, shock, and illnesses.
Renal anuria occurs when the kidneys themselves aren’t functioning properly and are failing to produce urine. This can be caused by certain drugs and medications, toxins in the body, autoimmune diseases, congenital kidney disease, muscle trauma, injury, or a number of other diseases.Postrenal anuria occurs when the structural problem is located after the kidneys, due to a blockage or obstruction preventing urine from flowing to the bladder. This could be due to a urinary tract infection or blockage, a mass in the bladder, prostate problems, and certain diseases.
Other possible causes of anuria include dehydration, infection, stroke, thrombosis, and high blood calcium concentrations.
Symptoms of Anuria
The primary symptom of anuria is decreased urine output. This can be accompanied by irritation and discomfort, dizziness, rapid pulse, light-headedness, a loss of appetite, weakness, and vomiting.
Remember, anuria is commonly a symptom of something else rather than a condition in and of itself.
Anuria may require a physical exam, blood tests, imaging scans, or renal scans to diagnose. Treating anuria requires identifying and treating the underlying cause. Possible treatment options may include the use of certain medications that enhance the amount of blood flow to the kidneys, such as Mannitol, Dextrose, and Dopamine. In addition, it could require altering medication intake, treating an underlying infection, restricting sodium and fluids from the diet, or even surgery to remove any structural blockages.
Anuria is a condition where the body is not producing enough urine, usually as the result of some other medical condition.
It can be a sign of kidney failure, and if left untreated may lead to heart failure, hypertension, anemia, platelet disorders, gastrointestinal problems, and even death. Anuria may occur when the kidneys aren’t getting enough blood, if the kidneys stop working, if there is a blockage preventing the outflow of urine, because of dehydration, as the side effect of certain medications, or because of another disease or infection. In addition to producing very little urine, a person with anuria might feel dizzy or light-headed, have a rapid pulse, or experience weakness and vomiting.
Treating anuria requires treating the underlying condition causing the problem.
