Renal tubular acidosis - distal; Renal tubular acidosis type I; Type I RTA; RTA - distal; Classical RTA

• Fatigue
• Weakness
• Confusion or decreased alertness
• Increased rate of breathing

• Many patients develop kidney stones.
• Breathing rate may be rapid as the body attempts to decrease carbon dioxide.
• Symptoms of osteomalacia or rickets, nephrocalcinosis, or electrolyte disturbances may appear.
• Blood pH and the urine pH may show inadequate hydrogen ion excretion. The urine pH is usually > 5.0.
• A urinalysis may show abnormalities including increased levels of calcium and potassium in the urine.
• An ABG (arterial blood gas) and blood chemistries may indicate metabolic acidosis and low blood potassium level.
