Distal renal tubular acidosis (dRTA) is a medical condition characterized by the kidneys' inability to effectively excrete acid in the urine. This can result in a buildup of acid in the blood, leading to a range of symptoms including fatigue, dehydration, and altered mental states. There are a number of synonyms for dRTA, including renal acidosis, hyperchloremic acidosis, and tubular acidosis type 1. These terms all refer to the same underlying condition, which can be caused by a variety of factors including genetic abnormalities, autoimmune disorders, or the use of certain medications. Treatment typically involves addressing the underlying cause and may involve medication or dietary interventions.
