Bartter syndrome is a group of rare, inherited kidney tubule disorders. The problem happens in a part of the kidney called the thick ascending limb of the loop of Henle. In this segment, healthy kidneys normally pull back (reabsorb) salt into the body. In Bartter syndrome, that “salt pump” does not work well. As a result, the body loses too much salt and water in the urine. This causes dehydration, a drop in the amount of fluid in the blood, and normal or low blood pressure. Because salt handling is broken, other minerals and acids also shift. People often have low potassium, low chloride, and metabolic alkalosis (the blood is too alkaline). Some patients also have high prostaglandin E2, and a few have low magnesium. These chemical changes can start before birth (antenatal form) or in early childhood (classic form). Common day-to-day problems include frequent urination, thirst, muscle cramps, and poor growth in children. NCBI+2Genetic Diseases Center+2
Bartter syndrome is a rare, inherited kidney salt-wasting disorder. A defect in salt transport in the thick ascending limb of the loop of Henle causes the kidneys to lose too much sodium, chloride, potassium (and sometimes magnesium) in urine. This salt loss leads to dehydration, thirst, muscle cramps, low or normal blood pressure, high renin and aldosterone (secondary hyperaldosteronism), and a typical blood picture called metabolic alkalosis; many people also have high prostaglandin E2 levels and nephrocalcinosis (calcium deposits in the kidney). There are several genetic types; some present before birth with polyhydramnios and prematurity, others later with poor growth, frequent urination, and weakness. Treatment focuses on replacing the lost electrolytes, reducing prostaglandin overproduction, protecting kidney function, and supporting growth and development across childhood and adulthood. Early diagnosis and steady treatment improve growth and long-term kidney outcomes. NCBI+2PMC+2
Other names
Doctors and websites may use several names for the same condition. You might see: “salt-wasting nephropathy,” “salt-losing tubulopathy,” “hyperreninemic hypokalemic alkalosis,” “antenatal Bartter syndrome,” “classic Bartter syndrome,” and simply “Bartter’s”. All point to the same core problem: kidney tubules cannot reabsorb salt properly, leading to salt loss, low potassium, and alkalosis. National Organization for Rare Disorders+1
Types
Scientists have found several gene changes (mutations) that cause slightly different forms of Bartter syndrome. Each type affects a protein that moves salt across the kidney tubule.
Type I (SLC12A1/NKCC2): Severe salt loss from birth; often presents before delivery with too much amniotic fluid (polyhydramnios) and preterm birth. PMC
Type II (KCNJ1/ROMK): Also begins very early; similar chemistry changes with heavy salt loss and low potassium. PMC
Type III (CLCNKB/classic Bartter): Tends to appear after the first year of life. Children have failure to thrive, low potassium, alkalosis, and high renin and aldosterone, with low-to-normal blood pressure. Orpha.net+1
Type IV (BSND, or digenic CLCNKA + CLCNKB “IVb”): Antenatal salt loss plus sensorineural deafness. Families may hear this called “Bartter with deafness.” Orpha.net
Type V (MAGED2-related, X-linked transient antenatal Bartter): Marked salt loss and polyhydramnios in pregnancy; symptoms can improve after infancy. Orpha.net
Big picture: all types share salt-wasting, low potassium, and alkalosis; the exact gene explains when symptoms start and whether special features (like deafness) appear. Orpha.net
Causes
“Cause” here means the underlying reasons the kidney’s salt pumps fail, plus a few “Bartter-like” situations doctors consider in practice:
Autosomal recessive mutations in SLC12A1 (Type I). The NKCC2 cotransporter is broken, so salt cannot move into tubule cells. PMC
Autosomal recessive mutations in KCNJ1 (Type II). The ROMK potassium channel fails; the loop’s salt transport stalls. PMC
Autosomal recessive mutations in CLCNKB (Type III). The chloride channel for salt handling in the loop underperforms. Orpha.net
Mutations in BSND (Type IVa). The barttin subunit is defective; kidneys and inner ear are both affected. Orpha.net
Digenic CLCNKA + CLCNKB defects (Type IVb). Two chloride channels together cause a similar picture with deafness. Orpha.net
X-linked MAGED2 mutations (Type V). Antenatal, transient form with severe prenatal salt loss. Orpha.net

Large genetic deletions/duplications in the same genes. Not just point mutations—copy-number changes also disrupt transport. kidney-international.org
Common symptoms
Frequent urination (polyuria). The kidneys cannot concentrate urine, so people pass large volumes. This drives thirst and night-time bathroom trips. NCBI
Excessive thirst (polydipsia). The body drinks more to replace water lost in urine and to keep blood pressure stable. NCBI
Salt craving. The brain senses sodium loss and pushes you to seek salty foods. National Organization for Rare Disorders
Fatigue and low energy. Low potassium and low body salt make muscles and nerves work less efficiently. NCBI
Muscle cramps and weakness. Potassium is vital for muscle function; when it is low, cramps and weakness are common. NCBI
Constipation or abdominal discomfort. Electrolyte shifts affect gut muscle movement and can cause belly pain. National Organization for Rare Disorders
Vomiting in infancy. Babies with antenatal or early forms may vomit, lose weight, and struggle to grow. Genetic Diseases Center
Poor growth/failure to thrive (children). Chronic salt and potassium loss hinder weight and height gain unless treated. Genetic Diseases Center
Dehydration episodes. Hot weather, fever, or diarrhea can tip the balance and cause rapid fluid loss. NCBI
Normal or low blood pressure. Despite high aldosterone, the body stays salt-depleted; this keeps pressure from rising. NCBI
Premature birth history (antenatal form). Many cases start with polyhydramnios during pregnancy and delivery before term. Genetic Diseases Center
Kidney calcium deposits (nephrocalcinosis). High urine calcium may leave tiny crystals in the kidney over time. PMC

Dietary molecular supplements
Use only with your clinician. Evidence below is general to the nutrient; dosing is individualized in BS to avoid stone risks or electrolyte swings.
Magnesium (e.g., magnesium oxide or citrate)
Why: Supports muscle/nerve function and potassium homeostasis when low. Mechanism: Co-factor in Na⁺/K⁺ ATPase and renal K⁺ handling. Typical ranges: Often 200–400 mg elemental Mg/day in adults (titrate to labs/tolerance). Note: Diarrhea is dose-limiting; monitor in CKD. Office of Dietary SupplementsVitamin D₃ (cholecalciferol)
Why: Bone mineralization support when deficient. Mechanism: Increases intestinal Ca/P absorption; supports bone remodeling. Dose: Based on 25(OH)D level and age; avoid oversupplementation due to hypercalciuria risk in BS. Office of Dietary SupplementsCalcium (if dietary intake is low and as advised)
Why: Adequate calcium intake is essential for bone; paradoxically, dietary calcium does not necessarily worsen stone risk if balanced with fluids. Mechanism: Supports bone matrix; binds oxalate in gut. Dose: Age-specific RDAs (e.g., 1000–1300 mg/day in many ages). Caution: Avoid excess; coordinate with nephrology. Office of Dietary Supplements+1Omega-3 fatty acids (EPA/DHA)
Why: General anti-inflammatory and cardiometabolic support in chronic illness; may help with overall well-being. Mechanism: Membrane lipid effects and eicosanoid balance. Dose: Common supplemental amounts 1 g/day EPA+DHA for general heart health; higher doses only under medical advice. Office of Dietary SupplementsOral rehydration solutions (ORS) packets
Why: Balanced sodium–glucose solutions improve fluid and electrolyte uptake during minor illnesses. Mechanism: SGLT1-mediated sodium-glucose co-transport enhances water absorption. Use: As directed during dehydration risk days. NCBICitrate (as potassium citrate only when indicated)
Why: For patients with hypocitraturia and calcium stones. Mechanism: Citrate binds calcium, reducing crystallization. Dose: Specialist-directed to urine chemistries. NCBIZinc (if deficient)
Why: Supports growth and immune function in children with poor intake. Mechanism: Enzymatic and growth factor functions. Dose: As per age and labs; avoid excess. NCBIMultivitamin (age-appropriate, low-dose)
Why: Fills minor dietary gaps without megadoses that could affect kidneys. Mechanism: Broad micronutrient coverage; avoid high fat-soluble vitamin loads. NCBIProbiotics (adjunct for GI tolerance of electrolytes)
Why: May improve GI tolerance where KCl causes upset; evidence general. Mechanism: Microbiome modulation; not disease-modifying. Dose: Per product; stop if intolerance. NCBIFolate/B12 (if labs show deficiency)
Why: Support hematologic health during chronic illness. Mechanism: DNA synthesis for red cell production. Dose: Clinician-directed based on labs. NCBI
Immunity booster / regenerative / stem-cell drugs
There are no FDA-approved “immunity boosters,” regenerative medicines, or stem-cell drugs for treating Bartter syndrome itself. Using such products outside of a regulated clinical trial can be unsafe or fraudulent. The evidence-based focus is on electrolytes, NSAID therapy in selected patients, RAAS modulation when appropriate, growth/nutrition support, vaccination, and kidney protection. If you’re interested in research, ask your nephrologist about IRB-approved clinical trials only. Safer alternatives include routine vaccines, nutrition correction, and targeted endocrine therapies (e.g., growth hormone only when GH deficiency is proven). NCBI+1
Surgeries / procedures
Most people with Bartter syndrome do not need surgery. Procedures are supportive for complications:
Gastrostomy tube (G-tube) for severe feeding/growth failure
Why: Ensures reliable calories/electrolytes in infants/children with poor oral intake. How: Endoscopic or surgical placement; supports catch-up growth with dietitian plans. PMCKidney stone procedures (e.g., ureteroscopy, shock-wave lithotripsy)
Why: For symptomatic stones or obstruction from nephrocalcinosis complications. How: Minimally invasive stone fragmentation/removal to protect renal function. kidney-international.orgCorrective orthopedic surgery for rickets deformities (selected cases)
Why: When genu varum/valgum persists despite medical correction. How: Osteotomy/guided growth to improve alignment and mobility. NCBI+1Central venous access (temporary)
Why: For difficult IV electrolyte therapy during severe illness. How: Short-term lines under sterile technique; removed once stable. NCBIKidney transplantation (rare, only for end-stage kidney disease)
Why: If long-standing complications progress to ESRD (uncommon with modern care). How: Standard transplant evaluation and surgery; underlying tubular defect is in native kidneys. PMC

Avoid: Unsupervised high-dose calcium or vitamin D (can worsen hypercalciuria). Office of Dietary Supplements
Avoid: Licorice products that can mimic aldosterone and worsen potassium loss. NCBI
Avoid: OTC NSAIDs beyond the plan; duplication increases GI/renal risk. FDA Access Data
Avoid: Very low-salt diets unless your nephrologist changes the plan. PMC
Frequently asked questions
Is Bartter syndrome curable?
No cure yet. Consistent electrolyte replacement, selected NSAIDs, and RAAS-modulating drugs help most people live full lives. NCBIWhy are prostaglandins high, and why do NSAIDs help?
Salt loss at the macula densa drives COX-mediated PGE2 overproduction; NSAIDs reduce PGE2, lowering urine salt loss and improving growth in many children. PubMed+1Will I always need potassium?
Most patients require long-term KCl plus potassium-sparing measures; doses change with age, diet, and other meds. PubMedCan Bartter lead to kidney failure?
With modern care most do well, but a minority develop CKD in adulthood; regular follow-up reduces risk. PMCIs hearing loss part of Bartter?
Some genetic forms (type 4) involve sensorineural deafness; routine hearing checks catch problems early. PMCWhat happens during illness (vomiting/fever)?
Losses jump; follow your sick-day plan (ORS, earlier labs) to prevent dangerous dips in potassium and volume. NCBIAre ACE inhibitors/ARBs safe?
Used selectively to lower RAAS drive; monitor K⁺/creatinine and stop in pregnancy due to fetal toxicity. FDA Access Data+1Is ibuprofen the same as indomethacin in BS?
Both are NSAIDs; indomethacin often has stronger effect on PGE2-driven salt wasting, but choice depends on tolerance and specialist judgment. StatPearls+1Do supplements cure Bartter?
No. Magnesium, vitamin D, calcium, and omega-3s can support health but don’t fix the tubular defect. Office of Dietary Supplements+1Can low magnesium block potassium correction?
Yes—hypomagnesemia makes hypokalemia harder to correct; fixing magnesium first often helps. Office of Dietary SupplementsWhy monitor kidneys with ultrasound?
To track nephrocalcinosis and stones and adjust care early. kidney-international.orgIs there a special diet?
Measured salt replacement, adequate fluids, potassium/magnesium sources, and careful vitamin D/calcium use—individualized to labs. PMC+1Are there stem-cell or regenerative drugs for BS?
No approved therapies—avoid unregulated products. Ask about clinical trials with proper oversight. NCBIWhat about pregnancy?
Management changes (e.g., avoid ACEi/ARB). Close obstetric–nephrology teamwork is essential. FDA Access DataHow often do we check labs?
Frequently in infancy/childhood; intervals lengthen when stable. Your team sets a schedule based on growth, symptoms, and meds. turkarchpediatr.org
