Bartter Syndrome

Disease database

Bartter Syndrome is a rare genetic disorder that affects the kidneys and causes a variety of symptoms. It is named after the American pediatrician Frederic Bartter, who first described the condition in 1962. This article will explore the different aspects of Bartter Syndrome, including its symptoms, causes, and potential treatment options.

Polyuria: Excessive Urination

One of the hallmark symptoms of Bartter Syndrome is polyuria, which refers to excessive urination. Individuals with this condition produce large amounts of urine, leading to increased frequency of urination. This can result in dehydration if not properly managed.

Polydipsia: Excessive Thirst

Alongside polyuria, individuals with Bartter Syndrome often experience polydipsia, which is excessive thirst. The body tries to compensate for the increased urine production by triggering a strong desire to drink fluids. This can lead to a constant need for hydration.

Dehydration: A Common Consequence

Due to the excessive urination and increased thirst, dehydration is a common consequence of Bartter Syndrome. It is essential for individuals with this condition to maintain proper fluid intake to prevent dehydration and its associated complications.

Hypokalemia: Low Potassium Levels

Bartter Syndrome also causes hypokalemia, which is characterized by low levels of potassium in the blood. Potassium is an essential mineral that plays a crucial role in various bodily functions, including muscle contraction and maintaining proper heart rhythm. The low potassium levels can lead to muscle weakness and irregular heartbeats.

Metabolic Alkalosis: Acid-Base Imbalance

Another characteristic feature of Bartter Syndrome is metabolic alkalosis, which refers to an imbalance in the body’s acid-base levels. This occurs due to excessive loss of chloride and potassium in the urine, leading to an increase in blood pH. Metabolic alkalosis can cause symptoms such as weakness, fatigue, and nausea.

Muscle Weakness: A Debilitating Symptom

Individuals with Bartter Syndrome often experience muscle weakness as a result of the electrolyte imbalances caused by the condition. The low potassium levels can affect the proper functioning of muscles, leading to weakness and fatigue. This can significantly impact an individual’s quality of life.

Growth Retardation: Impaired Development

Bartter Syndrome can also affect growth and development in children. The electrolyte imbalances and associated complications can interfere with normal growth patterns, leading to growth retardation. It is crucial for children with Bartter Syndrome to receive appropriate medical care and nutritional support to promote healthy growth.

Renal Salt Wasting: Impaired Salt Reabsorption

One of the underlying causes of Bartter Syndrome is renal salt wasting, which refers to the impaired reabsorption of salt in the kidneys. This leads to excessive salt excretion in the urine, resulting in electrolyte imbalances and the associated symptoms. The impaired salt reabsorption can also affect the body’s ability to regulate blood pressure.

Treatment Options for Bartter Syndrome

While there is no cure for Bartter Syndrome, there are treatment options available to manage the symptoms and improve quality of life. The primary goal of treatment is to restore electrolyte balance and prevent complications such as dehydration and muscle weakness.

Fluid and Electrolyte Replacement

Individuals with Bartter Syndrome may require fluid and electrolyte replacement therapy to maintain proper hydration and balance electrolyte levels. This may involve oral or intravenous administration of fluids and supplements to replenish the lost electrolytes.


Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) and potassium-sparing diuretics may be prescribed to help manage the symptoms of Bartter Syndrome. NSAIDs can help reduce excessive urine production, while potassium-sparing diuretics can help maintain potassium levels in the body.

Dietary Modifications

A well-balanced diet is essential for individuals with Bartter Syndrome to ensure adequate intake of essential nutrients. This may involve increasing the consumption of foods rich in potassium and other electrolytes. It is important to work with a healthcare professional or registered dietitian to develop a personalized dietary plan.

Regular Monitoring and Follow-up

Regular monitoring of electrolyte levels and kidney function is crucial for individuals with Bartter Syndrome. This helps healthcare professionals assess the effectiveness of treatment and make any necessary adjustments. It is important for individuals with this condition to maintain regular follow-up appointments with their healthcare team.

In conclusion, Bartter Syndrome is a rare genetic disorder that affects the kidneys and causes a range of symptoms, including polyuria, polydipsia, dehydration, hypokalemia, metabolic alkalosis, muscle weakness, growth retardation, and renal salt wasting. While there is no cure for Bartter Syndrome, treatment options are available to manage the symptoms and improve quality of life. It is important for individuals with this condition to work closely with their healthcare team to develop a personalized treatment plan and receive regular monitoring and follow-up care.
