Nephron Acidosis, commonly known as Renal Tubular Acidosis (RTA), is a medical condition where the kidneys fail to properly acidify the urine. This leads to an imbalance of acids and bases in the body, causing various health issues. This guide provides detailed information about nephron acidosis, including its definitions, causes, symptoms, treatments, and more, all explained in simple terms to help you understand this condition better.
Nephron Acidosis, or Renal Tubular Acidosis (RTA), is a condition where the kidneys’ tubules fail to remove acids from the blood efficiently. The nephrons are the functional units of the kidneys responsible for filtering blood, balancing electrolytes, and maintaining overall fluid balance. When nephrons malfunction, it leads to an accumulation of acid in the body, causing various health problems.
Pathophysiology
Structure
Nephrons consist of several parts, including the glomerulus, proximal tubule, loop of Henle, distal tubule, and collecting duct. Each part plays a crucial role in filtering blood, reabsorbing necessary substances, and excreting waste products.
Blood Supply
The kidneys receive blood through the renal arteries, which branch into smaller arterioles and capillaries within the nephrons. Proper blood flow is essential for filtering blood and removing waste products.
Nerve Supply
The kidneys are innervated by the autonomic nervous system, which regulates blood flow and filtration rates. Nerve signals help adjust kidney function based on the body’s needs.
Types of Nephron Acidosis
There are three main types of RTA:
- Type 1 (Distal RTA): Impaired acid secretion in the distal tubule.
- Type 2 (Proximal RTA): Impaired bicarbonate reabsorption in the proximal tubule.
- Type 4 (Hyperkalemic RTA): Associated with high potassium levels due to aldosterone deficiency or resistance.
Causes of Nephron Acidosis
Here are 20 possible causes of nephron acidosis:
- Genetic disorders
- Autoimmune diseases
- Kidney infections

Frequently Asked Questions (FAQs)
