Metabolic complication in CRF include all of the following except –
**Core Concept**
In chronic renal failure (CRF), the kidneys' inability to filter waste and excess fluids leads to electrolyte imbalances, acid-base disturbances, and altered glucose and lipid metabolism. Metabolic complications in CRF are a result of the kidneys' decreased ability to regulate these processes.
**Why the Correct Answer is Right**
Metabolic complications in CRF include hyperkalemia (elevated potassium levels), hyperphosphatemia (elevated phosphate levels), and secondary hyperparathyroidism. These conditions arise due to the kidneys' decreased ability to excrete potassium and phosphate, leading to their accumulation in the blood. Additionally, the kidneys' decreased ability to activate vitamin D results in impaired calcium absorption, contributing to secondary hyperparathyroidism.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not a metabolic complication of CRF. However, the specific choice is not provided, so we cannot evaluate its correctness.
* **Option B:** This could be a metabolic complication of CRF, but without the specific choice, we cannot confirm its correctness.
* **Option C:** This could be a metabolic complication of CRF, but without the specific choice, we cannot confirm its correctness.
* **Option D:** This could be a metabolic complication of CRF, but without the specific choice, we cannot confirm its correctness.
**Clinical Pearl / High-Yield Fact**
One important aspect to remember is that the metabolic complications of CRF can be influenced by the underlying cause of the kidney disease, such as diabetes or hypertension. Additionally, the management of these complications often involves phosphate binders, vitamin D analogs, and potassium-lowering agents.
**Correct Answer:** D.
