Acute kidney failure is a health condition that occurs when the kidneys suddenly become unable to filter waste products from the blood. As a result of inability to filter waste, high levels of wastes may accumulate in the kidneys and the blood’s chemical makeup may get out of balance. This condition develops rapidly, usually in less than a few days. This condition is most common in people who are already hospitalized, particularly in critically ill people who need intensive care. Although this condition can be fatal and requires intensive treatment, it can be reversible. If you’re otherwise in good health, you may recover normal or nearly normal kidney function.

The signs and symptoms of acute kidney failure include decreased urine output, fluid retention, causing swelling in your legs, ankles or feet, Chest pain, Nausea, Fatigue and Shortness of breath. Sometimes it causes no signs or symptoms and is detected through lab tests done for another reason. This type of kidney illness occurs when individuals have condition that slows blood flow to their kidneys, when individuals experience direct damage to their kidneys, when when the kidneys’ urine drainage tubes become blocked and wastes can’t leave your body through your urine.

Some of the conditions that may slow blood flow to the kidneys and lead to kidney injury include heart attack, liver failure, severe dehydration, blood pressure medication, and severe alergic reactions. Acute kidney failure almost always occurs in connection with another medical condition or event. Fluid buildupis one of the possible complications of Acute kidney failure, which can cause shortness of breath. This condition also incraeses the risk of chest pain, muscle weakness, permanent kidney damage, or even death. Preventions include carefully analyzing  over-the-counter (OTC) pain medications, maintaining a healthy diet, and managing the chronic health conditions such as diabetes and high blood pressure.
