Understanding the disease

This section has not yet been reviewed by a physician. It summarises patient information from sources such as MedlinePlus, Orphanet and the NHS in plain language. The disease can differ from person to person; talk to your doctor about diagnosis and treatment.

What happens in this disease?

The channels in the kidney that take back salt do not work well. Salt is lost in the urine; potassium and calcium are lost along with it. One type begins before birth and is more severe. The classic type begins in early childhood and is milder.

Which symptoms can occur?

Symptoms vary by type.

  • Too much amniotic fluid during pregnancy and a risk of early birth
  • Not gaining enough weight in infancy
  • Passing a lot of urine, dehydration and constipation
  • Low potassium in the blood; muscle weakness, cramps and tiredness
  • Loss of calcium in the urine and weak bones
  • Calcium deposits in the kidneys
  • Hearing loss (rare, in one type)

How is it diagnosed?

The levels of potassium, chloride and bicarbonate in the blood are checked. Salt and calcium are measured in the urine. A genetic test identifies the type. The type that begins before birth can be noticed by too much amniotic fluid during pregnancy.

Treatment and care

There is no treatment that cures the disease completely, but it can be controlled with lifelong treatment. Salt and potassium supplements are the main treatment. Medicines that reduce the loss in the kidneys are also used. Taking plenty of salt and water is recommended. For hearing loss, a cochlear implant can be done. Control usually becomes easier with age. The doctor who follows the disease decides which treatment is suitable.

For the family: inheritance and genetic counselling

It is passed on through recessive inheritance. The mother and father are usually healthy carriers. For a carrier couple, the chance of an affected child in each pregnancy is 1 in 4. In marriages between relatives, this chance may be higher. Genetic counselling is recommended.

News about Bartter

Clinical trials (ClinicalTrials.gov)

A clinical trial is a regulated study that tests whether a new treatment is safe and whether it works, in patients who volunteer. Most trials look for a certain age, genetic change and health condition. Taking part is voluntary.

This list is not a treatment recommendation. Treatments tested in phase 1–3 trials are investigational (experimental): their efficacy and safety have not yet been proven and they are not approved treatments. Taking part depends on each trial’s criteria and a physician’s assessment; the first step is to talk to the doctor who manages your care.

ClinicalTrials.gov currently lists no active interventional studies for this disease. Last checked: October 7, 2026.
