N25: Disorders resulting from impaired renal tubular function

Disorders resulting from impaired renal tubular function are a range of conditions that involve the malfunctioning of the tubules in the kidneys. These tubules play a crucial role in the process of filtering blood and creating urine. When they aren't functioning properly, various issues can arise, such as difficulty in maintaining balance of electrolytes, acid-base balance, and regulate blood pressure. Common manifestations may include abnormalities in urine output and composition, increased or decreased levels of various electrolytes in the blood, tiredness, nausea, muscle weakness, and in severe cases, irregular heartbeat and seizures. These disorders may result from hereditary factors, damage from use of certain medications, or systemic diseases like diabetes. Disease progression varies, but it often involves deteriorating kidney function over time, which can lead to chronic kidney disease or kidney failure.
