Acute kidney injury, previously called acute kidney failure, is a sudden decline in the kidneys’ ability to function properly. It can develop within a few hours or days and may become life-threatening without prompt medical attention.
The kidneys remove waste and excess fluid from the blood while helping the body maintain healthy levels of salts, minerals and other chemicals. When their function suddenly deteriorates, waste products can accumulate in the bloodstream and excess fluid may build up in the body.
Acute kidney injury can result from reduced blood flow to the kidneys. Severe dehydration, major blood loss, heart failure, serious infections and dangerously low blood pressure are among the conditions that can restrict the blood supply required for normal kidney function.
The condition may also arise from direct damage to kidney tissue. Possible triggers include inflammation, severe infections, toxic substances and some medicines. Certain medical imaging dyes may also increase the risk, particularly among people who already have kidney problems or other underlying health conditions.
Another cause is an obstruction in the urinary system that prevents urine from leaving the body. Kidney stones, an enlarged prostate and some tumors can create blockages that place pressure on the kidneys and interfere with their normal operation.
Some patients experience no obvious symptoms during the early stages, with the condition only identified through blood and urine tests. When symptoms develop, they may include passing less urine than usual, swelling of the legs or feet, nausea, fatigue, confusion, weakness and shortness of breath. Severe chemical imbalances can also affect the heart and other vital organs. NHS guidance confirms that reduced urine output, dehydration, confusion and drowsiness may be signs of the condition.
Treatment depends on the underlying cause. A patient with severe dehydration may require intravenous fluids, while an infection may be treated with appropriate medication. Doctors may stop or adjust medicines suspected of harming the kidneys, and urinary blockages may require a catheter or surgery. In serious cases, temporary dialysis may be needed to remove waste and excess fluid while the kidneys recover.
Unlike chronic kidney disease, which usually develops gradually, acute kidney injury may improve when it is detected early and its cause is successfully treated. Recovery is not guaranteed, however, and some patients may be left with lasting kidney damage or an increased risk of chronic kidney disease.
People who experience a significant reduction in urination, persistent vomiting, unexplained swelling, confusion or breathing difficulties should seek urgent medical care. These symptoms can indicate a serious condition that requires immediate assessment.
