Acute renal failure is now mostly known as acute kidney injury, some patients have no obvious symptoms in the early stage, and some patients will have nausea and vomiting, diarrhea, anorexia, decreased urine output, swelling and other symptoms.
Acute kidney injury refers to the clinical syndrome caused by a variety of reasons leading to a sharp, progressive decline in renal function in a short period of time (hours to weeks). The clinical course of a typical acute kidney injury can be divided into three phases, namely, the onset, progression and maintenance, and recovery.
Early stage is generally referred to as the onset stage, patients often suffer from some known or unknown etiological factors, but may not yet occur obvious renal parenchymal injury, so there are no obvious symptoms. Some patients may experience digestive symptoms, such as nausea, vomiting, diarrhea, and eructation (commonly known as hiccups). Some patients may also have decreased appetite, leading to anorexia.
If the kidney function has been damaged in the early stage, patients may have symptoms such as decreased urine output, deepened urine color, and edema in body parts.
When uncomfortable symptoms occur, it is recommended to go to regular hospitals in time for diagnosis and treatment by professional doctors to avoid delaying the condition.
