Electrolyte Imbalance: Symptoms, Causes, Treatment
اختلال توازن الكهارل
Electrolyte imbalance means levels of minerals such as sodium, potassium, calcium or magnesium are too high or low. Effects and treatment depend on the mineral, cause and speed of change.
What is Electrolyte Imbalance?
Electrolytes support fluid regulation and heart, muscle and nerve function. Imbalance does not always mean dehydration; excessive water intake can also cause problems.

Symptoms
Mild changes may be silent. Weakness, cramps, tingling or nausea can occur; severe disturbances may cause confusion, seizures or abnormal heart rhythms.
Causes
Vomiting, diarrhea, heavy sweating, kidney, heart or liver disease, hormonal disorders and medicines such as diuretics or laxatives can contribute.
Risk factors
Young children, older adults, people with kidney disease and those taking diuretics are more vulnerable. Fatigue or cramps alone do not determine a need for supplements.
Diagnosis
Blood testing is interpreted alongside fluid balance, kidney function and medicines. Urine tests, hormone tests or an ECG may be needed according to the abnormality.
Treatment
Treatment addresses the cause and determines replacement or removal of excess minerals at a safe rate. Some cases need intravenous treatment, dialysis or repeated monitoring.
Complications
Serious disturbances can damage heart, brain or muscle function. Inappropriate rapid correction, particularly of sodium disorders, can injure the nervous system and requires clinical supervision.
Prevention
Follow a fluid plan suited to your health and attend medicine monitoring. Oral rehydration suits selected problems; sports drinks or large amounts of water are not universal treatment.
When to see a doctor
New confusion, a seizure, fainting, severe weakness or palpitations requires urgent care. Persistent vomiting, reduced urination or inability to drink also needs assessment.
