Final answer:
Impaired kidney function can lead to abnormal fluid levels, electrolyte imbalances, elevated creatinine levels, and an increased risk of hypernatremia, significantly affecting overall health.
Step-by-step explanation:
An individual whose kidneys cannot adequately filter the blood supply may suffer from various health issues due to the critical functions the kidneys perform. Abnormal fluid levels can lead to dehydration and affect electrolyte balance, increasing the risk of conditions like hypernatremia (excessive sodium in the blood). Additionally, renal insufficiency is often indicated by elevated creatinine levels in the blood because when kidney function declines, their filtration capacity reduces, leading to the accumulation of waste products such as creatinine. Kidney dysfunction can also result in complications such as anemia, cardiovascular disease, and disturbed levels of potassium, calcium, and phosphate due to the interrelated nature of these elements in maintaining homeostasis. Thus, compromised kidney function can severely impact overall health.
