1. Electrolyte imbalances: Acute renal failure can lead to imbalances in electrolytes such as sodium, potassium, and calcium, which can affect various bodily functions and lead to complications such as muscle weakness, irregular heart rhythms, and seizures.
2. Fluid overload: The kidneys play a crucial role in regulating fluid balance in the body. When they are not functioning properly, fluid can accumulate in the body, leading to swelling, shortness of breath, and high blood pressure.
3. Metabolic acidosis: Acute renal failure can result in the accumulation of acidic waste products in the blood, leading to a condition known as metabolic acidosis. This can cause symptoms such as confusion, rapid breathing, and fatigue.
4. Uremia: Uremia is a condition in which waste products normally excreted by the kidneys build up in the blood. This can lead to symptoms such as nausea, vomiting, itching, and confusion.
5. Hypertension: Acute renal failure can cause an increase in blood pressure, which can further damage the kidneys and lead to complications such as heart disease and stroke.
6. Infections: Acute renal failure can weaken the immune system, making individuals more susceptible to infections. Infections can further complicate the condition and lead to sepsis, a life-threatening condition.
