Acute kidney injury
NATTHA PRAMONG , M.D.
Acute kidney injury is a group of symptoms characterized by a rapid decline in kidney function within hours or days, typically not exceeding 7 days. The main causes are shock or low blood pressure, leading to the accumulation of waste products in the blood, abnormalities in minerals and fluids in the body, and a reduced immune response. Prompt and appropriate diagnosis and care can help the kidneys return to normal function.
Symptoms of acute kidney injury:
- Decreased urine output: Some individuals may not urinate at all, or urinate less than 400 milliliters per day.
- Swelling of the arms and legs.
- Easy fatigue and weakness, even without exertion.
- Nausea and vomiting.
- Confusion and lethargy.
Causes of acute kidney injury:
- Decreased fluid volume in the body: such as from severe diarrhea, significant blood loss from gastrointestinal bleeding or internal organs, or sudden blood loss from trauma.
- Sudden low or high blood pressure.
- Medications or toxins, including dietary supplements and herbal remedies.
- Acute glomerulonephritis, caused by medications, infections, or autoimmune disorders attacking kidney tissue.
- Obstruction of the urinary tract, such as from kidney stones, enlarged prostate gland, or bilateral kidney swelling.
- Infection in the bloodstream.
Treatment:
- Address the underlying cause, such as discontinuing medications that may be causing the issue and ensuring adequate hydration in cases of fluid deficit or shock.
- Control blood pressure to normal levels.
- Avoid nephrotoxic substances and adjust medication dosages accordingly.
- Manage with renal replacement therapy in cases where the kidneys are unable to function properly, especially if there are severe electrolyte imbalances or pulmonary edema.
