Electrolyte Disorders Q&A

What are Electrolyte Disorders?

Electrolytes are natural elements or compounds normally found in your body that control important body functions. Calcium, chloride, potassium, sodium, phosphate, and magnesium are common electrolytes. They're present in your urine, blood, and other bodily fluids, as well as foods, dietary supplements, and some drinks.

Electrolyte disorders happen when electrolyte levels in your body are too low or too high. Electrolytes must stay balanced for your body to function the way it should. Electrolyte imbalances are harmful and dangerous in many cases.

What are the Symptoms of Electrolyte Disorders?

Common symptoms include:

  • Fast and irregular heartbeats
  • Nausea and vomiting
  • Fatigue
  • Seizures and convulsions
  • Diarrhea or constipation
  • Muscle cramping and weakness
  • Confusion and irritability
  • Abdominal cramping
  • Headaches
  • Tingling and numbness

Imbalanced electrolytes can cause serious medical problems like coma and heart attack. It's essential to see your doctor at the first sign of electrolyte abnormalities.

What Causes Electrolyte Disorders?

Many conditions can lead to electrolyte disorders when left untreated, including:

  • Prolonged vomiting, sweating, and diarrhea
  • Severe burns or broken bones
  • Medications
  • Acute or chronic kidney disease
  • Alcohol use disorder
  • Cirrhosis of the liver
  • Congestive heart failure
  • Thyroid disorders
  • Eating disorders
  • Adrenal gland disorders

How is it Diagnosed?

To find out if you have an electrolyte disorder, your specialist uses a simple blood test to assess your kidney function and the electrolyte levels in your body. They also test your reflexes and complete a physical exam. Your provider might order additional blood tests, urine tests, or an electrocardiogram (EKG) to evaluate your heart's function.

Treatment Options

Depending on severity and cause, treatment may include:

  • Intravenous (IV) fluids
  • IV medications
  • Oral medications
  • Dietary supplements
  • Diet changes
  • Dialysis

When to see a specialist

Should you see a specialist?

See a nephrologist for recurrent or unexplained electrolyte abnormalities, complex cases involving CKD or heart failure, electrolyte disorders that have not responded to primary care management, or any severe abnormality requiring nuanced fluid and electrolyte replacement.
