Overview Symptoms Treatment Prevention

Proximal renal tubular acidosis

• fatigue
• weakness
• confusion or decreased alertness
• increased rate of breathing
• muscle pain

• Your breathing rate may be rapid as your body attempts to decrease carbon dioxide.
• You may have symptoms of osteomalacia and rickets.
• You may be dehydrated from loss of water into the urine (low potassium levels interfere with the kidney's ability to concentrete the urine).
• Measurements of the blood pH and urine pH may show a problem. The urine may be alkaline, although this may change as the body becomes more acidic.
• A urinalysis may show abnormal levels of phosphate, calcium, glucose, and amino acids in the urine.
• Arterial blood gases and blood chemistries may indicate metabolic acidosis and electrolyte abnormalities.

• urine potassium level (high)
• blood potassium level (low)
• urine citric acid
• urine calcium
• acid loading test (pH)
