Hyperchloremia is a disorder in which a person has too much chloride in their blood. Chloride is an electrolyte, and changes in electrolyte levels can cause dehydration.
Electrolytes such as chloride, sodium, and bicarbonate are minerals that dissolve in the fluids of the body.
With careful management of fluids and food, and with prompt treatment for any underlying conditions, most people can regain normal electrolyte levels.
People with hyperchloremia have too much chloride in their bloodstream, often due to changes in the body's fluid levels. People undergoing chemotherapy have many risk factors for hyperchloremia. Treatment for hyperchloremia depends on the cause. It is not always possible to prevent hyperchloremia.
When the body is stressed, electrolyte levels may become imbalanced. The kidneys help regulate electrolyte levels, so electrolyte problems can signal a problem with the kidneys.
Hyperchloremia often points to another problem. People discover they have hyperchloremia as part of a collection of tests to measure electrolyte levels.
A doctor may order these tests if a person appears to have nutritional or fluid imbalances, kidney problems, or is undergoing chemotherapy.
